How much does it cost to build a mobile app?

Written by Bill Beltz, Founder of QUANT LAB USA INC·Published ·Updated

Direct answer

Building a mobile app in 2026 typically costs $20,000 to $400,000+, and the spread is real, not padding. A simple MVP on one platform runs $20,000 to $60,000; a mid-complexity app with a custom backend and user accounts runs $60,000 to $150,000; and a complex, consumer-scale app with real-time features and payments runs $150,000 to $400,000 or more. The single biggest cost lever is whether you build two native apps or one cross-platform codebase, followed by how much custom backend you need. These are vendor-neutral market ranges; QUANT LAB USA INC scopes mobile work case by case rather than quoting a fixed number sight unseen.

Quick facts

  • Simple MVP app, single platform: $20,000 to $60,000.
  • Mid-complexity app with a backend and accounts: $60,000 to $150,000.
  • Complex app with real-time, payments, and integrations: $150,000 to $400,000+.
  • Cross-platform (React Native, Flutter) is usually cheaper than two native builds.
  • Backend APIs and infrastructure are often 30 to 50 percent of total cost.
  • Budget 15 to 25 percent of build cost per year for maintenance.

2026 mobile app cost ranges by type

Simple MVP (single platform)

$20,000 to $60,000

8 to 14 weeks. A focused feature set, one or two screens of real logic, third-party login, and a lightweight backend. Built to validate an idea, not to scale to millions.

Mid-complexity app with backend

$60,000 to $150,000

4 to 7 months. User accounts, a custom API, push notifications, offline support, an admin panel, and either cross-platform or a single polished native target.

Complex / consumer-scale app

$150,000 to $400,000+

7 to 14 months. Real-time features, payments, chat, maps, third-party integrations, both iOS and Android native, plus the infrastructure to scale and observe it.

Cross-platform build (React Native / Flutter)

$40,000 to $180,000

One codebase ships to both stores. Typically 25 to 40 percent cheaper than two separate native apps, with a small tradeoff on the most hardware-specific features.

Backend and API layer

$15,000 to $90,000

Often quoted separately. Auth, data model, business logic, webhooks, and the deployment pipeline. This is frequently 30 to 50 percent of the all-in number.

Annual maintenance and updates

15 to 25 percent of build / year

OS updates, store policy changes, dependency patches, bug fixes, and small features. Skipping this is the most common reason apps quietly break.

Variables that move the quote

  • Native iOS + Android vs a single cross-platform codebase.
  • Whether a custom backend is needed or a managed service (Firebase, Supabase) fits.
  • Number of third-party integrations and the maturity of their APIs.
  • Real-time features (chat, live location, collaborative editing) and payments.
  • Design fidelity: a template-based UI vs a bespoke, animated brand experience.
  • Compliance scope (HIPAA, PCI DSS) and any required security review.

How to scope a build without overpaying

Start with the smallest version that proves the core idea, ship it, and let real usage decide what to build next. Most over-budget apps fail because they paid to build features nobody used. Insist on a fixed scope for the first release, owned source code and accounts, and a written estimate broken out by frontend, backend, and design so you can see where the money goes. A cross-platform codebase is the right default unless you genuinely need bleeding-edge native hardware features.
