Your CEO comes back from an industry event convinced that customers want an app. They would like a budget figure by the end of the week so it can go into next year’s plan. You search for an answer and find numbers ranging from a few thousand dollars to over a million, often on the same page.
So, how much does it cost to build an app? For a custom app built by a professional team, broad market estimates usually place a focused first version somewhere in the tens of thousands of dollars, a mid-complexity product in the low to mid six figures, and complex enterprise or regulated apps well beyond that. The spread is wide because “an app” can mean a single booking flow or a full platform with payments, integrations and strict security requirements. What you need is the specific set of decisions that moves your app from one end of that range to the other.
This guide explains those ranges, the cost drivers behind every quote, what you pay for in each phase, the costs that continue after launch, and how to build an estimate your finance team will accept.
How Much Does It Cost to Build an App at Each Level of Complexity?
The figures below are broad, typical market estimates for custom apps built by experienced teams. They are not quotes, and real projects vary with team location, rates, scope and how well requirements are defined. Use them to check whether a figure is in the right territory, not to set a final budget.
| App type | What it usually includes | Broad typical range |
| Focused MVP | One core user flow, one or two user roles, simple sign-in, basic backend, one platform or a shared cross-platform codebase | Roughly $40,000 to $100,000 |
| Mid-complexity app | Several roles and permissions, payments, notifications, admin dashboard, a few third-party integrations | Roughly $100,000 to $250,000 |
| Complex, enterprise or regulated app | Single sign-on, audit logs, deep integrations with internal systems, strict security and compliance work, high availability | Often $250,000 and up |
Timelines follow the same pattern. A focused first version often takes a few months from discovery to launch. Larger products take longer, and the extra time usually goes on integration, testing and review rather than screens.
Two caveats matter. First, these ranges cover the build only, and running costs start the day you launch. Second, the number of decisions still open when work begins often matters more than the category. A well-defined mid-complexity app can cost less than a vague MVP that changes direction three times.
The Cost Drivers That Move Your Number
Every app quote is a sum of effort, and effort comes from a short list of drivers. When two quotes differ wildly, one of these is usually the reason.
User roles and permissions
Each role, such as customer, staff member, manager or administrator, needs its own screens, rules and test cases. An app with one type of user is much simpler than one where five roles see different data and can take different actions. Permissions also multiply testing, because every action has to be checked for every role.
Features with hidden depth
Some features look small on a list and carry a lot of work underneath. Payments need error handling, refunds, receipts and reconciliation. Chat and real-time updates need infrastructure that keeps connections open and messages in order. Offline mode needs data syncing and conflict rules for when two people edit the same record. Search, notifications and file uploads each bring their own edge cases. When you review a feature list, ask which items involve money, real-time data or offline use, because those tend to dominate the estimate.
Integrations
Connecting to a CRM, ERP, payment provider, identity service or clinical system is often where estimates fall short. Every external system has its own rules, rate limits, test environments and quirks, and older internal systems may have little documentation. Ask any vendor to list each integration and estimate it separately. If an integration involves a system nobody on your side fully understands, budget extra time for discovery.
Platforms and build approach
Building separate native apps for iOS and Android means two codebases. A cross-platform framework such as React Native lets most of the code serve both platforms, which usually lowers the cost of a typical business app. Native development still makes sense when you need heavy graphics, advanced device features or the highest possible performance. If you need a web app as well, include it in the scope from the start, since shared design and backend work can serve all three.
Design depth
A product built from an existing design system costs less to design than one that needs a new visual language, custom illustrations and detailed animation. Research and usability testing add cost up front and usually save more by preventing rework later.
Security, accessibility and compliance
Apps that handle health, financial or personal data need careful access control, encryption, audit trails, security testing and documentation. Accessibility, such as screen reader support, sufficient contrast and tap targets that meet the WCAG guidance, costs far less when it is designed in from the start than when it is retrofitted. If your app touches regulated data, involve your compliance and legal advisers early. Requirements they add late can reshape flows that are already built.
Team model and location
Rates vary widely by country, seniority and engagement model. A lower hourly rate does not always mean a lower total, because less experienced teams may need more hours and more rework. Compare proposals on total cost for the same defined scope, not on hourly rate.
What You Pay For in Each Phase
A professional app build moves through a few phases. Knowing what each one produces helps you spot where a low quote is cutting corners.
Discovery and UX design. The team works out who the users are, which flows matter most and what the first release must prove. Output includes user flows, wireframes and a tested prototype. This phase is usually a modest share of the budget, and it is the cheapest place to change your mind. Moving a screen in a prototype takes an hour. Moving it after it is connected to live data can take days.
Engineering. Usually the largest share of the budget. Frontend work covers the screens people use. Backend work covers the database, APIs, business rules, user accounts and the admin tools your team will rely on every day. The backend is often larger than people expect, because most of what makes an app trustworthy happens there. Your choice of cloud platform also shapes long-term cost and scalability; this guide on why AWS is a good fit for enterprise apps covers the trade-offs for larger products.
Quality assurance. Manual and automated testing across devices, operating system versions and network conditions, plus performance and security checks. Quotes that are vague about testing tend to produce launches full of bug reports.
Release. App store submission, analytics, crash reporting, monitoring and a plan for urgent fixes in the first weeks. App store review can also take time, so plan launch dates with a buffer.
If you want a first release scoped this way from the start, M7’s MVP development team builds focused first versions using a build, measure, learn cycle, so you spend on the features that prove demand and keep time and cost to a minimum.
Running Costs After Launch
The build is only the first bill. Plan running costs into the first budget so the app does not stall a year after launch.
Maintenance. Bug fixes, security patches, library updates and changes needed for new iOS and Android releases. A common rule of thumb is to set aside a meaningful share of the original build cost every year, often quoted around 15 to 20 percent, more if the app changes frequently or depends on many integrations.
Hosting and services. Cloud hosting for a small app can be modest. Costs grow with users, data, media storage and traffic, because most cloud services charge by usage. Add third-party services such as email and text message delivery, maps, search, analytics and monitoring.
AI features. If your app includes AI features such as smart search or an assistant, model usage is billed per request or by volume of text processed, so costs rise with use. Set spending alerts and limits before launch, and plan for human review of outputs where accuracy matters.
App store fees. Apple’s Developer Program costs $99 a year and Google Play charges a one-time $25 registration fee. Both stores also take a commission on digital goods and subscriptions sold inside the app, generally 15 or 30 percent depending on the program and your revenue. Physical goods and services usually go through a payment processor instead, which charges its own transaction fees.
Ongoing improvement. Very few apps are finished at launch. Budget for regular releases based on what users do, rather than treating the first version as the final product.
A three-year view gives leadership a far more honest figure than build cost alone. Add up the build, three years of maintenance, hosting and services, store fees and a realistic budget for improvements. That total is the number to compare against the value the app is expected to bring.
How to Build an Estimate You Can Defend
A defensible estimate shows its working, so anyone can see where the money goes and what would change it.
- Define the first release around one core flow. Write down the single task the app must do well for launch, the users who do it and how you will measure success.
- List roles, features and integrations. Mark each feature as must-have or later, and flag anything involving payments, real-time data, offline use or regulated information.
- Estimate hours by role. Break the work into product, design, frontend, backend, QA and project management, then multiply by each role’s rate.
- Add external costs. Include licenses, hosting, third-party services, security testing and store accounts.
- State a contingency and its purpose. Name the unknowns it covers, such as an undocumented integration. A visible contingency is more honest than padded line items.
- Validate with a prototype before full funding. A clickable prototype tested with real users shows which features matter before engineering money is committed.
When comparing vendors, send everyone the same scope, flows, platforms, integrations and acceptance criteria, and ask for costs by phase and role. Then check what each includes: discovery, testing, accessibility, security work, launch support and a warranty period. A low quote that leaves these out often costs more by the end.
For simple internal tools or early tests of demand, no-code platforms can be a reasonable starting point. They become limiting when you need complex logic, custom integrations or full control of your data. Our comparison of no-code vs custom code explains where each approach fits.
Ways to Reduce App Development Cost Without Hurting the Product
- Phase the roadmap. Launch the core flow, measure how people use it, then fund the next phase based on evidence.
- Choose cross-platform where it fits. For most business apps, one shared codebase serves iOS and Android well.
- Reuse proven components. A design system and shared component library make every release after the first faster.
- Settle decisions before engineering starts. Many budget overruns come from changes made after code exists.
- Cut features, not testing. Removing QA saves money for a few weeks and costs much more after launch.
Get a Number You Can Plan Around
The honest answer to app cost is a range that narrows as your decisions get clearer. Define the first release, understand which cost drivers apply to you, include running costs in the plan, and insist that every quote covers the same work.

Frequently Asked Questions
Why do app development quotes vary so much?
Quotes differ because vendors make different assumptions about scope, integrations, testing and team seniority. One quote may include discovery, QA and launch support while another leaves them out. Send every vendor the same written scope and ask for a breakdown by phase so you can compare like with like.
How much does it cost to run an app each month?
It depends mainly on users, data and third-party services. A small app with modest traffic can be inexpensive to host, while a busy app with media, real-time features or AI can cost far more. Maintenance and store fees come on top of hosting.
Is it cheaper to build a web app or a mobile app?
A web app is often cheaper for a first version because it runs on one platform with no store submission. A mobile app makes more sense when users need device features such as the camera, push notifications or offline access. Many products start on the web and add mobile once usage proves demand.
Can AI tools make app development cheaper?
AI coding assistants can speed up routine engineering work, which may trim some hours. Design decisions, architecture, security review and testing still need experienced people. Treat AI-assisted development as a modest efficiency, not a reason to halve a budget.
