How Much Does It Cost to Build an App in 2025?
App development costs range from $8,000 for a simple MVP to $150,000+ for a full-featured enterprise app. Here's what actually drives the number — and how to scope your project to get an accurate estimate.
TL;DR
Cost ranges at a glance
Simple MVP
$8,000 – $25,000
4–8 weeks
Core user flow (1–3 screens of real value)
Authentication and user accounts
Basic backend API and database
One platform (iOS or Android, not both)
Full-Featured Product
$25,000 – $80,000
8–16 weeks
Multiple user flows and feature sets
Payment integration (Stripe or equivalent)
Push notifications and in-app messaging
Admin dashboard for operations
Enterprise / Complex
$80,000 – $200,000+
16–40 weeks
Complex business logic and workflows
Enterprise SSO (SAML, OIDC)
Compliance features (audit logs, HIPAA, SOC2-readiness)
Multiple platform targets

Variables
What drives the cost
| Factor | Lower cost | Higher cost | Impact |
|---|---|---|---|
| Number of platforms | Web only or iOS only | Web + iOS + Android | high |
| Complexity of backend | Simple CRUD with basic auth | Real-time sync, complex business logic, multi-tenant | high |
| Third-party integrations | 0–2 integrations (auth + payment) | 10+ integrations with unreliable APIs | medium |
| Custom design | Standard UI components with light customization | Fully custom design system from scratch | medium |
| Compliance requirements | None (consumer app) | HIPAA, SOC2, PCI DSS | high |
| Offline support | Online-only app | Offline-first with sync and conflict resolution | medium |
Increases cost
What adds to the budget
- Adding Android to an iOS-only scope (doubles mobile cost)
- Real-time features — WebSockets and live sync are expensive to build correctly
- Compliance requirements (HIPAA, SOC2) add weeks to architecture and testing
- Redesigning scope mid-project — scope changes after build starts are costly
- Rushed timelines — compressed schedules require more parallel work and higher rates
Reduces cost
How to manage the budget
- Start with one platform and add the second after validation
- Use existing infrastructure (Supabase, Stripe, Clerk) instead of building from scratch
- Fix the scope before development starts — scope creep is the #1 cost driver
- Begin with a focused MVP — 5 features done well beats 15 features done poorly
- Provide clear wireframes or references — ambiguous design requirements cost rework time
Plan ahead
Hidden costs to budget for
- App Store developer accounts ($99/year for Apple, $25 one-time for Google)
- Cloud infrastructure — expect $50–$500/month depending on traffic
- Third-party service subscriptions (Twilio, Stripe, SendGrid, etc.)
- Bug fixes and maintenance — budget 15–20% of development cost annually
- App Store updates required when iOS or Android releases new OS versions
Perspective
The real cost of going cheap
Offshore agencies quoting $5,000 for a full-featured app aren't lying — they're just optimizing for a different outcome. The delivery is technically a working app, but the architecture is fragile, the code is unmaintainable by any engineer who didn't write it, and you'll spend the same or more fixing it in 12 months. Good engineering costs more upfront because it's solving the problem correctly, not just satisfying the brief.
FAQ
Common questions
Why do app estimates vary so much?+
Because 'build me an app' means different things. A simple to-do list MVP is not the same project as a real-time collaborative app with payments and push notifications. The estimates you see online are for different scopes — always compare like for like.
Can I get a fixed price for my app?+
Yes, for well-scoped projects. Fixed prices require a detailed specification upfront. If the scope changes during development, the price adjusts. Time-and-materials engagements give more flexibility but less budget certainty.
Is it cheaper to build a web app or a mobile app?+
Web apps are generally cheaper because there's one codebase and no App Store review process. Mobile apps add platform complexity, device testing, and App Store submission overhead.
