App Development Cost Breakdown: Where the Money Actually Goes

An app development cost breakdown is supposed to show the arithmetic under a headline number, and almost every page offering one splits the money by the stage of work instead. Discovery, design, development, testing, deployment. That split describes how a seller organises a project. It says nothing about what a login costs, and nothing about whether the half-working thing already on your laptop covers any of it.

This page takes the other axis. Every row below is a piece of an application you can point at, and against each one sits a figure a named seller publishes for building it, copied from that seller’s own cost guide with the guide’s own date attached. Two of the four sellers read here itemise features individually, which is rare on this search, and it is the reason a mobile app development cost breakdown can be written as a shopping list rather than as a project plan.

The last column is the part nobody publishes. If an AI builder wrote your first version, some of these rows already exist in the generated code, and one of them almost never does.

An app build’s money goes into a list of things that get built. Orbix Studio’s 2026 cost guide prices an email and password login at $2,000 to $4,000 and live in-app chat at $10,000 to $25,000. An AI builder usually produced several of those rows already, and almost never the one that proves they work.

Four sellers who publish a cost guide were opened on 30 August 2026 and read only for the rows they itemise: one of them prices sixteen individual features, one prices feature groups and single integrations, and two price whole platforms, and every figure below is copied from those pages with the seller and that page’s own date against it. Two further pages that rank on this search, one belonging to a database company and one to an app-industry publisher, refused an automated read with an HTTP 403, and nothing here is described from either. No seller was contacted and nothing was bought. The last column of the first table is not a price at all: it is what AxonBuild’s own study of 26 audited applications repeatedly found in code an AI tool had already written.

Where the money goes on an app build, line by line

Orbix Studio, whose guide sits at orbix.studio/blogs/mobile-app-development-cost-guide and carries the date 3 August 2026, is the only page met on this search that puts a dollar figure against individual features. MTechZilla, at mtechzilla.com/blogs/mobile-app-development-cost-guide-2026, dated 3 February 2026 and credited on the page to Muskan Kataria, does the same job one level coarser, pricing groups of features and, usefully, one outside integration on its own. Both addresses are printed rather than linked, and so is every other seller’s below, since all four of them make their money selling exactly the work being priced here.

Prices checked 30 August 2026, each one against the seller’s own guide. Both guides revise themselves without notice.

Read the first row again, because it is the whole point of the page. A named seller has put a price on signing in, as a thing on its own, rather than on a discovery stage or a design stage that happens to contain it. Once one seller has done that, a quote you have been given stops being a single number and becomes a list you can argue with.

Signing in is also the row that shows how much the phrase “one feature” is hiding. Orbix Studio prices email and password at $2,000 to $4,000, social login through Google or Apple at $3,000 to $6,000, fingerprint or face unlock at $5,000 to $8,000, a second factor at $6,000 to $10,000, and single sign on at $8,000 to $20,000. That is one line on a cost structure for app development spanning ten times over, and the difference is entirely which of those five things somebody meant when they wrote “authentication” on your quote.

Money behaves the same way. A standard checkout flow through Stripe is $6,000 to $12,000 on the same Orbix Studio page, dated 3 August 2026. Billing the same customer every month is $10,000 to $18,000, because a subscription needs a record of who is currently paying, what happens when a card fails, and what the application does on the day somebody cancels. Splitting a payment between two parties, which is what a marketplace needs, is $8,000 to $20,000. Three prices, one word.

The live rows are where the number climbs fastest. Orbix Studio puts live in-app chat at $10,000 to $25,000 and watching somebody move on a map in real time at $15,000 to $30,000. Its two AI rows sit at opposite ends of the same subject: calling a model somebody else trained is $5,000 to $15,000, training your own is $80,000 to $150,000, and a recommendation engine is priced from $25,000 and up. Calling a model is cheap to build and then charges you forever, so what the model calls themselves cost once people are using it is counted separately from the work of wiring one in.

The admin view is the row most people forget they are buying. Somewhere a human has to refund an order, unlock an account or delete a post. Orbix Studio, on 3 August 2026, prices a basic one at $8,000 to $15,000 and one with analytics, bulk actions and moderation at $20,000 to $40,000. Nobody demonstrates the admin view in a pitch, and everybody needs it by week three.

MTechZilla, on 3 February 2026, groups the same territory more coarsely, and the groups are worth reading because a lot of quotes arrive at exactly this resolution. Core features are $5,000 to $15,000. Payment and subscription features together are $8,000 to $25,000. Real-time features are $10,000 to $30,000. Advanced search and recommendations are $6,000 to $20,000. AI and machine learning are $15,000 to $50,000 and up. Security and compliance work is $8,000 to $30,000. The most useful figure on that page is the last one: each third-party integration is $3,000 to $15,000, per integration. That is the only published price found anywhere on this search for the row a founder thinks of as connecting the application to the mail tool the business already pays for, and it is the row that multiplies while nobody is counting, because an application with a payment provider, a mail sender, a maps key and an analytics account has four of them.

What one person charges for an hour, or for a single named piece of work, is a different set of numbers from the rows on a build quote, and it has its own sources: what one person charges to work on an app sets those out. The same money sorted by the stage of work a seller passes through, with the hour rate that multiplies it, is set out where those quotes are taken apart. What the builder subscription and the credits add before any human is paid is counted separately again.

The lines no published cost table has a row for

As of 30 August 2026, none of the four cost guides read for this page prices file upload and storage as a line of its own, and none of them prices getting the finished build through store review.

Both are things you will pay for. File handling is five jobs wearing one name: where the file physically goes, who is allowed to fetch it back, what happens when somebody uploads a 400 MB video, what the application does with a file type it did not expect, and what the bill looks like when a thousand customers have each uploaded ten photographs. An application that accepts a profile picture has already opened all five questions. None of the guides read here has a row for any of them, so on a phase-shaped quote it disappears inside “development” and on a feature-shaped quote it disappears entirely.

Store submission is the same story with a harder edge, because it has a deadline attached. The build has to be signed, described, screenshotted, given a privacy answer for every permission it asks for, and then survive a review it can fail for reasons nobody warned you about. Two of the four guides read do name store fees as a category of hidden cost in prose, and neither of them puts a figure against the work of getting through the review itself. What the two stores charge to publish is a separate and well-documented number, which covers none of the days somebody spends on a rejected submission.

There is a reason these two rows keep falling off. A published cost guide is a sales document. It is written to make a large number feel organised, and the rows that make a buyer feel organised are the ones they can picture: a login screen, a payment button, a chat window. Nobody pictures a storage bucket policy. So the guides itemise the rows that photograph well and leave the rest inside a phase.

The meters that keep charging every month after launch are a different sum from the one-off work of wiring them in, and that sum has its own inputs. Storage is the clearest case: the work of accepting a file is paid once, and the bill for holding it arrives every month for as long as the application exists.

Simple, medium and complex, as three sellers actually price them

Almost every page on this search sorts applications into three tiers with a band against each. Two of the four guides read here publish that ladder in full, and they are more useful side by side than either is alone.

Prices checked 30 August 2026. Monterail’s page, at monterail.com/blog/software-development-cost-breakdown-by-project-type, is marked updated 28 August 2026 and its rows are the mobile-app rows of a wider software development cost breakdown. Orbix Studio’s ladder carries timelines with it: 6 to 12 weeks at the simple tier, 3 to 6 months in the middle and 6 to 18 months at the top. MTechZilla puts no band against each of three tiers, and instead prices an MVP stage at $15,000 to $40,000 over 2 to 4 months, which is the same reader asking the same question with a different word.

Now read the two columns against each other. The simple-app floor is $8,000 on Monterail’s ladder and $10,000 on Orbix Studio’s, and MTechZilla’s MVP figure begins at $15,000, all three read on 30 August 2026. Those are close enough to read as a floor for the three scopes those sellers describe, and no more than that, because each seller means something different by simple. The ceilings are not close at all: Monterail stops climbing at $30,000 and up, and Orbix Studio keeps going to $500,000 and up. The gap between the cheapest published simple figure and the top of the most expensive complex one is more than fifty times over, from three sellers all publishing in 2026 about the same product category.

That gap is a disagreement about vocabulary rather than about money. Monterail’s simple tier means a single platform, read-only content and a minimal backend. Orbix Studio’s simple tier means 8 to 15 screens with basic authentication. Monterail’s complex tier means two native codebases with real-time chat or tracking and a dedicated backend. Orbix Studio’s complex tier means 40 or more screens with real-time features and machine learning in them. Each of those words measures a feature list, and the feature list is the thing in the first table.

So a tier band is only useful backwards: find the tier whose description matches what you are actually asking for, then check that the rows in the first table add up somewhere near the band. If they do not, one of the two is wrong, and it is worth knowing which before you sign anything. One number for the whole build, rather than the rows it is made of, is the question next door. A figure worked out for your own project, taken from a table rather than from a form that wants your email address first, is a separate job to this one. And whether a delivery application or a booking application costs more than a plain one turns on which of these rows that kind of application happens to need.

Does Flutter, React Native or a hybrid build change the number?

One shared codebase is priced below two native builds by both sellers who publish both numbers. Orbix Studio, on 3 August 2026, puts a medium Flutter application at $35,000 to $85,000 against $70,000 to $150,000 for both platforms built natively. The framework moves the number less than the feature list does.

Prices checked 30 August 2026. Orbix Studio’s platform figures are all stated for a medium application. MTechZilla prices one shared codebase as a single band covering React Native and Flutter together and does not separate the two, so its figure repeats on both of those rows.

Seasia Infotech publishes a third set on the same axis, at seasiainfotech.com/blog/app-development-cost, dated 27 February 2026: iOS at $30,000 to $150,000, Android at $20,000 to $100,000 and cross-platform at $40,000 to $200,000.

Two things are worth pulling out of those three sets. The first is that the saving from one shared codebase is real and roughly halves the platform bill on the page that prices both approaches, which matches the shared-code figures Orbix Studio publishes alongside them on 3 August 2026: about 85 percent shared for Flutter, about 80 percent for React Native, and nothing shared when both are built natively. On price, Flutter is the cheaper of the two at both ends of that page’s band, by a margin small enough to be a rounding difference on a number this size.

The second is that iOS and Android do not price the same way across sellers. Two of the three publish iOS above Android: $40,000 to $80,000 against $35,000 to $70,000 on Orbix Studio, 3 August 2026, and $30,000 to $150,000 against $20,000 to $100,000 on Seasia Infotech, 27 February 2026. MTechZilla, on 3 February 2026, prices them identically at $30,000 to $150,000 each. Anyone telling you confidently that one platform costs more is describing their own shop, not the market.

Hybrid, Ionic and Xamarin are the same trade under older names: one codebase, shared across both platforms, at some cost in how native the result feels. None of the four guides read on 30 August 2026 gives Ionic, Xamarin or Cordova a cost row of its own. Only one names Xamarin at all, inside a list of cross-platform frameworks with no figure against it. Read that as the market having collapsed the choice down to two names rather than as an absence of data.

The web-side versions of this question, including what a progressive web app or a Python web application costs, are not answered by any of the mobile bands above and should not be estimated from them. A site that only describes a business is priced from a much shorter list than any of this. The same rows priced for something that runs in a browser and holds customer accounts come out at different numbers, and that comparison is made separately. And one system built for one business, rather than an application aimed at a store or a public audience, is priced on its own terms.

Where the money can honestly come out

Four levers move the number, and all four are visible in the figures above rather than in anybody’s negotiating position.

Cut screens. Orbix Studio’s tier boundaries, on its page dated 3 August 2026, are counted in screens: 8 to 15, then 20 to 40, then 40 or more. The jump from its simple band to its medium band is $10,000 to $50,000 becoming $50,000 to $150,000, and the thing that moves you across that boundary is a screen count you control. Half the screens in a first version exist because somebody sketched them, not because a customer asked.

Cut one platform. On that same Orbix Studio page, one shared codebase at $35,000 to $85,000 against both platforms built natively at $70,000 to $150,000 is the single largest structural saving published anywhere in this set. Launching on one platform first can save as much or more, depending on scope: on the same page one native platform is $35,000 to $70,000 or $40,000 to $80,000, which overlaps the shared-codebase band rather than sitting below it.

Cut the admin view down to what a human genuinely has to do by hand. The distance on Orbix Studio’s page between a basic panel at $8,000 to $15,000 and an advanced one at $20,000 to $40,000 is bulk actions, analytics and moderation tooling, most of which is a database query and a person for the first six months.

Buy the rows one at a time. Nothing in the first table has to be bought in the same month as everything else, and the rows that make money are not the rows that make demos. Buying one of these rows on its own, months later, when the rest of the application is already running, is a narrower purchase than any line on a build quote.

One row should not be cut, and only one row above is cheaper. Orbix Studio, the only page here that prices testing at all, puts it at $3,000 to $8,000 for a medium app, against $6,000 to $12,000 on the same page for the payment flow it exists to protect. Cutting it moves the work rather than removing it, onto whoever finds the failure, which is usually a customer whose card got charged twice.

Nobody can put a figure against any of these rows for your application until they have seen a short, specific set of things, and that set is spelled out on its own. Whether these rows are bought by the hour or as one named price changes who carries the risk when a row takes longer than anybody thought. And starting the whole thing again, rather than paying for the rows that are missing, is a decision with its own arithmetic.

What changes when an AI builder wrote the first version

Every figure above assumes a build starting from nothing. If a builder has already produced a working first version, the arithmetic changes in a specific and lopsided way: the rows that photograph well are usually there, and the row that proves any of them work usually is not.

That pattern is the third column of the first table, and it is worth being precise about where it comes from. Of the 21 third-party applications in the findings ledger of AxonBuild’s fixed 26-application study, audited across June and July 2026 in three groups, where each finding was confirmed against the code and not by pattern, at least 18 had no automated test that ran anywhere. How the 26 audited applications scored sets out the rest of that study, including the pillars and the cohort rules. The ledger keeps notable findings, so that count is a floor rather than a ceiling.

Set that against the cost table honestly. Only signing in is priced lower, and testing is the row an AI builder reliably skips, which is a bad combination: it is the row that gets dropped from a build quote to save money and the row that was already missing before anybody was hired.

The visible rows do genuinely arrive, and that is real value rather than a consolation. A generated application usually has a login screen that works, a payment flow that reaches a card form, an admin page and screens that hold together in a demo. What it does not have is the second half of each of those: the reset path, the webhook, the check that stops a customer opening the admin page, the storage rule. Every one of those is a missing part of a feature already on the screen, and a seller pricing a from-scratch build has no row for a part, so the whole row gets quoted instead.

This is where finishing a part costs less than a build and a build gets quoted anyway. AxonBuild works on the missing parts of apps that AI tools already built. Show Bilal which screens exist and what does not happen behind them on a free 20-minute video call. If you want him to build the missing pieces, he checks the code and gives you a fixed quote for those pieces rather than for the whole row, and you pay after you see them working.

Tidying an application that already exists is a different market with its own published prices, and what tidying up an already-written app is quoted at collects them. What it costs to get an application that mostly works over the line and in front of paying users is a shorter and more specific list than this one. What it costs to pay a human to keep the application working, once it is built, is counted apart from the build.

What to do with this before you pay anybody

Take the quote you have and read it against the first table, row by row, out loud. Most quotes arrive with three or four line items and a total, and the useful question to put to them is which of the eight rows above sit inside those line items and which ones do not. Whether the total is fair follows from that answer and cannot be settled before it.

People often arrive at this search having already been given a total, wanting to know which parts of it they are still paying for. Ask which rows are in the number. Ask what happens to the rows that are not: whether they are a later invoice, a change request, or something the seller assumes you will never need.

Then ask the two questions the guides do not cover. What does this quote assume about files and uploads, and who does the store submission if the first attempt is rejected. Both of those are real work, neither has a published price, and a seller who has thought about them will answer quickly.

There is no spreadsheet at the end of this page and no file to download. The table is the breakdown, and a figure with a seller’s name and a date against it is worth more than a template with your own guesses in it. Why the same list of rows comes back at one price from one seller and many times that from another, and what the cheapest quote leaves out, is answered on its own.

Common questions about app development cost breakdowns

What is actually included in an app development cost breakdown?

Most published breakdowns include the stages a seller works through: discovery, design, development, testing and release, with a share of the total against each. A smaller number, including two of the four read for this page on 30 August 2026, break it down by feature instead, giving a price to a login, a checkout, a chat window or an admin panel. The feature version is the more useful one for checking a quote, because a feature is a thing you can say yes or no to.

How much does a simple app cost to build?

The two guides read here that publish a simple tier put it at $8,000 to $15,000 (Monterail, 28 August 2026) and $10,000 to $50,000 (Orbix Studio, 3 August 2026), and a third prices an MVP stage at $15,000 to $40,000 over 2 to 4 months (MTechZilla, 3 February 2026). The floors are close and the ceilings are not, because each seller means something different by “simple”: one means a single platform with read-only content, the other means 8 to 15 screens with basic authentication.

Is there a template or a spreadsheet for an app development cost breakdown?

Plenty of sellers offer one, usually behind an email form, and the number it produces is generated from assumptions you cannot see. The table earlier on this page is the same information without the form: named rows, published figures, and the seller and date against each. Copy the rows into whatever you already use. A breakdown is only worth anything if you can trace every figure in it back to a page that published it.

Does Flutter cost less than building for iOS and Android separately?

Yes on both pages that publish both numbers. Orbix Studio, on 3 August 2026, puts a medium Flutter application at $35,000 to $85,000 against $70,000 to $150,000 for both platforms built natively, and MTechZilla, on 3 February 2026, puts one shared codebase at $40,000 to $180,000 against $60,000 to $300,000 and up for two separate native applications. The saving comes from shared code, which the first page puts at about 85 percent for Flutter and about 80 percent for React Native.

How much of an app build is testing?

The only one of the four guides read that prices testing as its own line puts professional quality assurance testing during development at $3,000 to $8,000 for a medium app (Orbix Studio, 3 August 2026), less than the same page charges for a standard checkout flow at $6,000 to $12,000. It is also the row most likely to be missing from an application a builder generated, which is why it is worth confirming out loud whether a quote includes it.

What does it cost to add one feature to an app that already works?

No guide read here prices that, because all four price building from nothing. What they do publish is the from-scratch price of individual features, which is a scoped comparison point rather than an estimate: adding a second factor to a login that already works is usually less work than the $6,000 to $10,000 Orbix Studio charges, on its page dated 3 August 2026, to build that factor from nothing, though an existing app whose login has to be reworked to accept it can cost more than the from-scratch figure. Buying one row on its own, later, is a narrower purchase and it gets quoted differently.

How do I reduce software development costs without ending up with less app?

Cut screens before you cut features, launch on one platform instead of two, keep the admin view minimal for the first six months, and buy the rows in the order that the application actually needs them rather than all at once. Every one of those is visible in the published figures: the tier bands are counted in screens, and one shared codebase is priced at roughly half of two native builds. Cutting the testing row saves the least and costs the most later.

Does an AI builder actually remove any of these lines?

It removes part of several and all of none. The visible rows, meaning login screens, checkout flows and admin pages, usually arrive in some working form, while the row that proves any of them behave is usually absent: a fixed study of 26 applications audited across June and July 2026 counted at least 18 of its 21 third-party applications with no automated test that ran. What is left to buy is the second half of each row, meaning the reset path, the payment confirmation, the permission check and the tests, which is a different purchase from a build.
