How Much Does It Cost to Build an App? A Real Breakdown for 2026
Ask five app development shops to quote the same project and you will get five numbers that do not resemble each other. One says $12,000. One says $140,000. Both are describing “your app.” Neither is necessarily lying.
The spread is real, and it comes from a handful of concrete decisions about scope, platform, and who is doing the work. Once you can name those decisions, quotes stop being mysterious and start being comparable. This guide walks through each cost driver, gives ranges we actually see in the market, and explains what you pay after launch, which is the part most people forget to budget for.
If you want a number before you finish reading, run your idea through the free app cost calculator. It asks about the same drivers described below and gives you a range in about two minutes.
The seven things that actually set the price
1. How many platforms you ship
Building for iOS only is the cheapest starting point. Adding Android does not double the cost anymore, because most agencies build with a cross-platform framework like React Native or Flutter and share 80 to 90 percent of the code between the two.
Expect the second platform to add roughly 15 to 30 percent, not 100 percent. If someone quotes you double for Android, ask whether they are writing two fully native codebases and why your app needs that. Sometimes the answer is legitimate: heavy camera work, Bluetooth peripherals, background audio, and platform-specific hardware integrations do push toward native. Most business apps do not.
A web dashboard alongside the mobile apps is a separate build. Do not assume it is bundled.
2. Whether you need a backend
This is the single biggest fork in the road.
An app with no backend stores everything on the device. Think a workout timer, a unit converter, a habit tracker without sync. These are genuinely cheap to build, often in the $6,000 to $15,000 range, because there is no server to design, deploy, secure, or maintain.
The moment users need accounts, sync across devices, shared data, admin tooling, or anything that outlives a phone reset, you need a backend. That means a database, an API, hosting, and a way for you to see and manage the data. Backend work commonly adds $8,000 to $40,000 depending on how much logic lives there.
Managed platforms like Firebase or Supabase cut this substantially for standard patterns. Custom infrastructure costs more and is worth it less often than people expect.
3. Authentication and user accounts
“Just let people log in” is never just anything. A production auth system includes signup, login, password reset, email verification, session handling, account deletion (Apple requires an in-app path to delete an account if you offer account creation), and usually social login via Apple and Google. Apple specifically requires Sign in with Apple if you offer other third-party login options.
Budget $2,000 to $6,000 for standard auth on a managed platform. Multi-tenant permissions, team accounts, or role-based access push it higher because every screen then needs to know who is allowed to see what.
4. Payments and subscriptions
If you sell digital content or features inside the app, Apple and Google require you to use their in-app purchase systems and take a cut, 15 percent for most small developers under the reduced-rate programs, 30 percent above that. Implementing in-app purchase properly means receipt validation, restore purchases, subscription state handling, and testing across sandbox accounts. That is typically $3,000 to $8,000 of work.
Selling physical goods or services delivered outside the app is different. There you can use Stripe directly and keep the standard card processing rate.
Getting this wrong is one of the more common App Store rejection causes.
5. Design
There are three tiers, and they cost very differently.
- Template-driven. Standard iOS and Android components, your colors and logo, sensible layouts. Fast, cheap, and honestly fine for internal tools and MVPs. Often folded into the build price.
- Custom UI. Bespoke screens, a real design system, illustration or motion work, prototyped and reviewed before code starts. Usually $5,000 to $20,000 as a line item.
- Brand-led product design. Research, user testing, multiple concept directions. $20,000 and up, and appropriate mostly for funded companies where the app is the product.
Design is also where scope creep hides. Every extra screen is design plus build plus test.
6. Store submission and launch
Submission itself is not expensive, but it is fiddly and it is real work: developer accounts, signing certificates and provisioning profiles, app icons in every required size, screenshots for multiple device sizes, store listing copy, a privacy policy URL, and Apple’s App Privacy questionnaire declaring exactly what data you collect and how it is used.
Reasonable range is $1,000 to $3,000 if an agency handles it end to end. You can reduce this yourself using free tools, for example a privacy policy generator and a screenshot generator that produces correctly sized store images.
7. Ongoing costs after launch
This is the line item that surprises people, so here are the real numbers.
- Apple Developer Program: $99 per year, mandatory to keep an app on the App Store.
- Google Play Developer: $25, one time.
- Backend hosting: $0 to $50 per month for small apps on a managed platform’s free or entry tier. Costs scale with usage, not with time.
- Push notifications, email, SMS: usually $0 to $40 per month at small scale. SMS is the expensive one.
- Domain and marketing site: $15 to $200 per year.
- Maintenance: iOS and Android ship major releases annually and break things. Dependencies get deprecated. Budget 10 to 20 percent of the original build cost per year to keep the app working, more if the app is core to your business.
An app you build and then completely ignore for two years will usually stop working or get pulled from the stores. Plan for maintenance the way you plan for insurance.
Honest ranges by project type
These are market ranges for competent work delivered by a US-based team or a good boutique shop, not the cheapest possible number.
| Project | Typical range |
|---|---|
| Single-platform utility, no backend | $6,000 – $15,000 |
| Two platforms, accounts, simple data sync | $15,000 – $35,000 |
| Marketplace or booking app with payments | $35,000 – $90,000 |
| Social app with feeds, media, moderation | $60,000 – $150,000 |
| Regulated (health, finance) with compliance work | $100,000+ |
Offshore teams quote well below these. Large US agencies quote well above. Both can be the right answer depending on your situation and how much of the project management you want to own yourself.
Why quotes vary 10x for the same brief
Four reasons, in rough order of impact.
The brief was ambiguous. “A booking app” can mean a form that emails you, or a two-sided marketplace with calendars, payouts, and dispute handling. Vague briefs get priced defensively, which means high. Writing a tight spec is the cheapest cost reduction available to you. Our free app brief wizard walks you through the questions agencies need answered.
Hourly versus fixed price. Hourly quotes are estimates that can move. Fixed-price quotes include a risk buffer but the number is the number. Compare them knowing that.
Who is doing the work. A $150/hour US senior engineer and a $25/hour offshore junior produce very different quotes and very different codebases. Speed of delivery and quality of handoff differ too.
What is included. Some quotes cover design, QA, store submission, and 30 days of post-launch fixes. Some cover code only. Always ask for the exclusions list, not just the inclusions.
How to actually get a number you can trust
Write down the specific screens your app needs. List every place data has to persist beyond the device. Decide, on paper, what version one does not do. Then get three quotes against that same written document.
We publish fixed pricing rather than quoting per project, because the estimating process itself is where most of the confusion comes from. You can see how the process works and what we have shipped in the portfolio.
If you would rather talk it through than fill out a form, book a call and bring your list of screens.
Your app. In the stores. Done for you. US APP Team designs, builds, and launches your iOS and Android app for a fixed price. Start your app brief or book a free intro call — both are free.
