How Much Does It Cost to Build a Mobile App? A Practical Guide
What drives mobile app development cost: scope, design, backend, store fees and maintenance, plus a step-by-step method to estimate your own app's budget.
Mobile app development cost depends on three things: how many screens and features you need, how complex the backend is, and who builds it at what hourly rate. A clickable prototype can take a few weeks; a multi-role app with payments, real-time features and an admin panel can take many months. Instead of quoting made-up averages, this guide shows you what drives the cost and gives you a method to estimate your own app.
Why “average app cost” numbers are misleading
You will find many articles quoting average app prices. They usually mix very different things: a two-screen utility and a marketplace with three user roles, or a freelancer’s rate and a large agency’s rate. The spread is so wide that an average tells you almost nothing about your app.
A better approach is to break the app into parts you can estimate, then multiply by the rate of the team you are talking to. That is how we estimate projects, and it is the method we describe below.
The main mobile app development cost drivers
1. Features and screens
Every feature needs UI, logic, error handling, empty and loading states, and tests. Some features are much more expensive than they look:
- Cheap-ish: static content screens, simple forms, settings, onboarding slides.
- Medium: login and registration, profiles, lists with search and filters, push notifications, image upload.
- Expensive: payments and subscriptions, real-time chat, maps and location tracking, offline mode with sync, video, bookings with availability rules, anything with several user roles.
- Very expensive: custom AI features, complex integrations with legacy systems, hardware/Bluetooth devices, heavy regulatory requirements (health, finance).
2. Platforms and framework
Building separate native apps for iOS and Android means two codebases. Cross-platform frameworks such as React Native and Flutter let one team ship both from a single codebase, which usually lowers the build and maintenance cost. Platform-specific work (widgets, some permissions, store setup) still exists. See React Native vs Flutter if you are still choosing.
3. Design
Design ranges from “use a well-built component library with your colours” to fully custom illustration, motion and branding. Budget for:
- User flows and wireframes
- Visual design for each screen and state
- A small design system (colours, type, components)
- Usability testing with a few real users
Skipping design rarely saves money. It moves the cost into rework after launch.
4. Backend and admin tools
Most apps are only the front end of a system. The backend often costs as much as the app itself:
- API and database
- Authentication, roles and permissions
- File storage, email and push notification services
- An admin panel so your staff can manage users, content and orders
- Integrations (payment provider, CRM, ERP, analytics)
Backend-as-a-service platforms can reduce this for simple apps. Custom backends make sense when you have complex business rules or data you must control. Our REST API design guide covers what a good API needs.
5. Quality, security and compliance
Testing on real devices, automated tests, crash reporting, security reviews and privacy compliance (GDPR, data deletion requests) all take time. If your app handles health, financial or children’s data, plan for extra work.
6. Store publishing
Getting through App Store and Google Play review takes some work: screenshots, descriptions, privacy labels, test accounts for reviewers, and sometimes a rejection and resubmission. Our post on app store rejection reasons lists the common ones.
Store and platform fees (as of September 2026)
These are the fixed costs of being in the stores. Always check the official pages, because they change.
| Fee | Amount | Source |
|---|---|---|
| Apple Developer Program | US$99 per membership year (local prices vary; fee waivers exist for eligible nonprofits, accredited educational institutions and government entities) | Apple |
| Google Play Console | US$25 one-time registration fee | Google Play Help |
| Apple commission on digital sales | 15% under the App Store Small Business Program for developers with up to US$1M in proceeds; standard rate above that | Apple |
| Google Play service fees | Tiered by revenue, product type and region; Google updated the structure for the EEA, UK and US in 2026 | Google Play Help |
Commissions only apply to digital goods and subscriptions sold through the stores’ billing. Physical goods and services (for example food delivery or taxi rides) use your own payment provider, which charges its own fees.
Two other practical points:
- New personal Google Play accounts must run a closed test with at least 12 testers opted in for 14 continuous days before they can publish to production (Google Play Help). Plan the time for it, or register as an organisation if that fits.
- Google Play requires new apps and updates to target a recent Android API level. From August 31, 2026 that is Android 16 (API level 36) for most apps (Android Developers). Apple has similar rules for minimum Xcode and SDK versions. These rules are one reason maintenance is never optional.
Rough scope tiers
Instead of prices, here are scope tiers you can map your idea to. Place your app in a tier, then use the estimation method below to size it.
| Tier | Typical scope | What usually makes it this size |
|---|---|---|
| Prototype / MVP | 5–10 screens, one user role, basic login, simple backend or BaaS | Proving demand, investor demos |
| Standard business app | 15–30 screens, notifications, payments or bookings, admin panel, integrations | Serving real customers daily |
| Complex platform | Multiple roles (e.g. customer, provider, admin), real-time features, offline sync, heavy integrations | Marketplaces, logistics, fintech, health |
A worked estimation method
This is a simple method you can use with a spreadsheet. The numbers below are illustrative only, not a quote. Replace them with your team’s estimates and rates.
Step 1: List features and rate complexity
Write down every feature and give it a size in days of development effort (small = 1–2, medium = 3–5, large = 8–15).
Feature Size Days (dev)
Email + social login M 4
User profile and settings S 2
Product list, search, filters M 5
Product detail S 2
Cart and checkout (payments) L 10
Order history S 2
Push notifications M 3
Admin panel (orders, products) L 10
Backend API and database L 12
------
Subtotal 50Step 2: Add the work that isn’t features
Features are only part of the job. Add percentages on top of the subtotal:
Design (UX + UI) +20% 10
QA and device testing +20% 10
Project management / meetings +10% 5
Store setup and release fixed 3
------
Total 78 daysStep 3: Add a contingency
Requirements change, and integrations surprise everyone. Add 15–25% contingency. At 20%, 78 days becomes about 94 days.
Step 4: Multiply by the rate
Multiply total days by your team’s daily rate. Rates vary a lot by region, seniority and engagement model. Ask vendors for their rate and their breakdown, and compare breakdowns, not only totals.
Step 5: Add yearly running costs
Hosting and backend services monthly, scales with users
Third-party APIs (maps, SMS...) usage-based
Apple Developer Program yearly
Maintenance and updates ongoing (see below)Maintenance: the cost people forget
An app is never “done”. Every year you can expect:
- OS updates. New iOS and Android versions change permissions, UI behaviour and APIs.
- Store requirement updates. Target API levels, SDK minimums and privacy rules move forward on a schedule.
- Framework and library upgrades. Security fixes and deprecations in React Native, Flutter and your dependencies.
- Bug fixes and small improvements based on user feedback and crash reports.
- Infrastructure costs that grow with your user base.
A common planning approach is to reserve a yearly maintenance budget as a share of the original build cost. The right share depends on how actively you plan to develop the app after launch. Ask your vendor what they include.
How to reduce cost without hurting quality
- Cut scope, not quality. Launch with the smallest set of features that solves the core problem. Keep a written “later” list.
- Use cross-platform unless you have a clear reason for native.
- Use proven services for auth, payments, push notifications and analytics instead of building them.
- Design first. A clickable prototype tested with five users catches expensive mistakes before code is written.
- Automate releases with CI/CD so every build and store upload does not cost developer time.
- Plan the admin panel early. Adding it late often means reworking the backend.
Checklist before you ask for quotes
- One-paragraph description of the problem and target users
- List of user roles
- Feature list, marked must-have / nice-to-have
- Platforms (iOS, Android, web, tablet)
- Existing systems to integrate with
- Data sensitivity and compliance needs
- Design expectations (brand guidelines? existing designs?)
- Who will own maintenance after launch
- Target launch date and budget range
A vendor who receives this list can give you a much more accurate estimate, and you can compare quotes fairly.
Key takeaways
- There is no meaningful average price. Estimate from your feature list.
- The backend and admin panel often cost as much as the app screens.
- Store fees are small (US$99/year for Apple, US$25 once for Google Play as of September 2026). Commissions and maintenance matter more.
- Add design, QA, project management and 15–25% contingency on top of feature estimates.
- Budget for maintenance every year: OS updates and store rules make it mandatory.
