Key takeaways
- Most US agency projects land in three bands: roughly $25k–$60k for a simple app, $60k–$150k for mid-complexity, and $150k–$400k+ for complex products.
- Scope drives cost more than anything else: the number of user roles, integrations, offline behavior and compliance needs move the price faster than screen count.
- Building one shared codebase for iOS and Android usually costs less than two native apps, but not half as much.
- Plan for ongoing costs of roughly 15–20% of the initial build per year for maintenance, OS updates, hosting and third-party services.
- The most reliable estimates come after a short discovery phase that turns ideas into prioritized user stories.
The short answer: typical app cost ranges
There is no single price for an app, but there are reliable patterns. When we scope projects for US founders and product teams, the cost to develop an app tends to fall into one of three bands based on how much the product has to do, how many systems it talks to and how much risk it carries.
The ranges below are typical market estimates for work done by a US-based or US-managed agency. They vary with scope, team location and quality expectations, so treat them as planning anchors rather than quotes.
| Complexity | What it usually includes | Typical cost range | Typical timeline |
|---|---|---|---|
| Simple | One user role, 8–15 screens, email or social login, basic content, no complex backend logic | $25k–$60k | 2–4 months |
| Mid-complexity | Two or three roles, payments, push notifications, admin panel, a few third-party integrations | $60k–$150k | 4–7 months |
| Complex | Real-time features, marketplace or multi-tenant logic, heavy integrations, offline sync, regulated data | $150k–$400k+ | 7–12+ months |
| MVP | Narrow first release that tests one core workflow with real users | $30k–$90k | 2–4 months |
If you want a deeper breakdown by platform and feature, our mobile app development cost guide goes line by line through the components that make up these numbers.
What actually drives the price
Clients often ask how many screens they can get for a given budget. Screen count matters, but it is a weak predictor. Two apps with 20 screens each can differ in cost by a factor of three because of what happens behind those screens.
- User roles and permissions. A customer app plus a provider app plus an admin console is effectively three products sharing one backend.
- Integrations. Payment processors, EHR systems, ERPs, shipping carriers and identity providers each add design, development and testing time, and some come with their own certification steps.
- Real-time and offline behavior. Live chat, location tracking and offline-first data sync require extra architecture work and much more testing.
- Backend and data model. A thin backend on a managed platform costs far less than a custom API with complex business rules, reporting and audit trails.
- Design depth. A clean, system-based UI is cheaper than custom illustration, motion design and branded components on every screen.
- Security and compliance. Handling health, payment or student data adds encryption, access logging, vendor agreements and review cycles.
Compliance is the factor most often underestimated. A telehealth product built with HIPAA requirements in mind needs audit logging, careful choice of hosting and messaging vendors that will sign a BAA, and stricter session handling. That work is necessary, and it belongs in the budget from day one.
How your platform choice changes the budget
Building separate native apps in Swift and Kotlin means two codebases, two sets of UI work and two test suites. A shared codebase in Flutter or React Native lets one team ship to both stores with most of the code in common.
In our experience, cross-platform app development typically saves around 25–40% compared with two fully native apps of the same scope. It is rarely a 50% saving, because design, backend, QA on real devices and platform-specific polish still have to happen for each store.
| Approach | Relative cost | When it fits |
|---|---|---|
| Single native platform (iOS or Android) | Lowest initial cost | Your audience is concentrated on one platform |
| Cross-platform (Flutter or React Native) | About 1.2–1.5x a single native app | You need both stores with a shared roadmap |
| Two native apps | About 1.7–2x a single native app | Heavy platform-specific features or strict performance needs |
| Progressive web app | Often lower than a mobile app | Browser access is enough and app store presence is optional |
What common features typically cost
Estimating by feature is a useful sanity check on any proposal. The figures below are typical ranges for implementing each feature on a cross-platform app with its backend support, at US agency rates. They overlap and are not additive in a simple way, because shared infrastructure such as authentication and the API layer is built once.
| Feature | What drives the range | Typical cost range |
|---|---|---|
| Sign-up and login | Email only vs social login, SSO, multi-factor authentication | $3k–$10k |
| User profiles and settings | Number of fields, media uploads, privacy controls | $2k–$6k |
| Push notifications | Simple broadcasts vs segmented, event-driven messages | $2k–$8k |
| In-app payments | One-time checkout vs subscriptions, refunds, payouts to providers | $5k–$20k |
| Chat and messaging | One-to-one text vs group chat, media, read receipts, moderation | $8k–$30k |
| Maps and location | Static maps vs live tracking, geofencing, route calculation | $4k–$25k |
| Admin dashboard | Basic content management vs reporting, roles and audit logs | $8k–$35k |
| Offline mode and sync | Read-only caching vs two-way sync with conflict resolution | $8k–$40k |
Notice how wide some ranges are. Chat that sends text between two users is a modest task. Chat with attachments, moderation tools, typing indicators and message history across devices is a product in itself. When a feature carries a wide range in an estimate, ask which end your version sits at and why.
Where the money goes, phase by phase
Knowing how a budget splits across phases helps you spot estimates that skip something. If a proposal shows almost nothing for QA or discovery, the cost has not disappeared. It will show up later as rework.
| Phase | Typical share | What you get |
|---|---|---|
| Discovery and planning | 5–10% | Prioritized backlog, architecture outline, risk list, refined estimate |
| UX/UI design | 10–15% | User flows, wireframes, clickable prototype, design system |
| Development (mobile, backend, admin) | 45–55% | Working app builds, APIs, integrations, admin tools |
| QA and testing | 15–20% | Test plans, automated tests, device testing, bug fixing |
| Project management and release | 8–12% | Sprint planning, demos, store submission, launch support |
These percentages shift with the project. A data-heavy enterprise tool spends more on backend work, while a consumer app competing on experience spends more on design and usability testing.
Hourly rates and team location
Most estimates are built from hours multiplied by a blended rate. Typical US agency blended rates run roughly $100–$200 per hour, depending on seniority mix and specialization. Nearshore and offshore teams quote lower rates, often in the $35–$100 range.
Lower rates do not automatically mean a lower total. Time zone gaps, more review cycles and rework on unclear requirements can erase the difference. What matters is the cost of shipping a working, maintainable product, not the cost of an hour.
Ongoing costs most first estimates leave out
Launch is not the end of spending. Every app needs updates for new iOS and Android releases, security patches for dependencies, monitoring and occasional fixes for edge cases real users find.
- Maintenance and updates: commonly 15–20% of the initial build cost per year.
- Hosting and infrastructure: from under $100 a month for a small app to several thousand for high-traffic or data-intensive products.
- Third-party services: maps, SMS, email, analytics, video, search and crash reporting often charge by usage.
- Store accounts: Apple's developer program is $99 per year and Google Play charges a one-time $25 registration fee.
- Payment and store commissions: platform fees on in-app purchases and processor fees on card payments.
Budgeting for a maintenance and support plan up front avoids the common situation where a launched app slowly falls behind OS changes until it needs an expensive rescue.
An illustrative estimate, step by step
To make the math concrete, consider a hypothetical appointment booking app for a regional chain of physical therapy clinics. This is an illustration of how we build an estimate, not a quote.
- Patient app on iOS and Android built with one cross-platform codebase.
- Booking, reminders, secure messaging and card payments.
- Web admin panel for clinic staff to manage schedules.
- Integration with an existing practice management system.
A scope like this commonly lands between 700 and 1,000 hours across design, mobile, backend, QA and project management. At a blended rate of $130 per hour, that works out to roughly $91k–$130k, which sits in the mid-complexity band. Because it touches health information, we would add time for audit logging and vendor review, and the client would need a BAA with their hosting and messaging providers.
How to lower cost without cutting corners
- Start with an MVP that proves one core workflow. Our MVP development cost breakdown shows what a focused first release typically includes.
- Use managed services for authentication, push notifications and file storage instead of building them from scratch.
- Choose a design system early so screens are assembled from tested components.
- Cut features, not quality. Removing QA or code review saves money for a month and costs more for years.
- Keep one decision-maker on your side who can answer product questions within a day.
The cheapest feature is the one you never build. Discovery workshops often remove 20–30% of the initial wish list simply by asking which features users need on day one.
Budgeting mistakes we see most often
Overruns rarely come from a single bad decision. They build up from small assumptions that nobody wrote down. These are the patterns we see most often when reviewing budgets that went off track.
- Spending the whole budget on version one. Keep 20–30% in reserve for changes driven by real user feedback after launch.
- Forgetting the admin side. Staff need tools to manage users, content, refunds and support requests, and those tools take real effort to build.
- Treating integrations as plug and play. Vendor APIs have rate limits, sandbox quirks and approval processes that add weeks.
- Ignoring content and data preparation. Product catalogs, onboarding copy and help content have to come from somewhere.
- No budget line for post-launch marketing. A finished app with no acquisition plan rarely reaches enough users to learn from.
A realistic plan accounts for each of these explicitly, even if the amount is small. It is easier to release unused contingency than to find new money mid-project.
How to get an estimate you can plan around
A trustworthy estimate shows its assumptions. It lists features, platforms, integrations, what is out of scope and the rate or team composition behind the number. If a vendor gives you a single figure after a 20-minute call, ask how they got there.
When comparing vendors, our guide on how to evaluate an app development partner covers the questions that reveal whether an estimate is realistic. If you are ready to put numbers against your own idea, you can request a scoped project estimate and we will outline ranges by phase along with the assumptions behind them.
Frequently asked questions
Can I build an app for under $25,000?
It is possible for a very narrow app, such as a single-purpose utility, a prototype or a content app built on templates. Below that level, teams usually cut design, testing or backend work, which tends to cost more later. For a product you plan to grow, a focused MVP in the $30k–$90k range is a more realistic starting point.
Why do quotes for the same app vary so much?
Vendors make different assumptions about scope, quality and who handles backend, design and QA. One quote may include an admin panel and automated tests while another leaves them out. Ask each vendor to list features, exclusions and team composition so you can compare like for like.
Is it cheaper to hire freelancers than an agency?
Freelancers often have lower hourly rates, but you take on the work of coordinating design, development, QA and releases yourself. For small, well-defined tasks that can work well. For a full product, the coordination overhead and gaps in testing often narrow or erase the savings.
How much should I budget after launch?
A common planning figure is 15–20% of the initial build cost per year for maintenance, plus hosting and third-party service fees. Active products that ship new features regularly spend more, because ongoing development is effectively a continuation of the build.
