Cost by development method
| Method | Upfront cost | Timeline | Best for |
|---|---|---|---|
| US/UK agency | $50,000–$375,000+ | 4–9 months | Funded companies, compliance-heavy apps |
| Offshore agency | $25,000–$150,000 | 3–6 months | Clear specs, budget-conscious |
| Freelancers | $5,000–$50,000 | 2–6 months | Well-scoped small projects |
| DIY (learn to code) | ~$0 + 6–18 months | Very long | Career changers, not founders |
| AI app builder | $0–$500/month | Days–weeks | MVPs, indie apps, validation |
Cost by complexity (traditional development)
- Simple (MVP): $10,000–$40,000 — single-purpose, no complex backend.
- Medium: $40,000–$150,000 — auth, payments, database, integrations. Most consumer apps live here.
- Complex: $150,000–$300,000+ — realtime at scale, compliance, custom infrastructure.
Where it goes: design 10–20%, development 60–70%, QA and management 10–15%. That distribution matters because AI generation collapses the middle chunk — the 60–70% — which is why the two columns in the method table differ by two orders of magnitude.
The costs nobody puts in the quote
- Maintenance: 15–25% of build cost per year (OS updates break things annually on schedule).
- Backend hosting: $0–25/month at MVP scale (Supabase/Firebase free→Pro tiers); $50–$2,000+/month at real scale.
- Store fees: Apple $99/year, Google Play $25 once; 15–30% commission on in-app revenue.
- Third-party APIs: maps, SMS auth, analytics — typically $0–100/month early on.
- The rebuild. The least-discussed cost: v1s get rewritten. Agencies charge again; with an AI builder a rewrite is a re-prompt.
What an app actually costs with AI in 2026
Concrete indie-founder budget, taking a subscription app from idea to App Store the AI-builder way:
| Item | Cost |
|---|---|
| AI builder subscription (2 months of building) | $0–100 |
| Apple Developer Program | $99/yr |
| Google Play | $25 once |
| Backend (managed, MVP scale) | $0–25/mo |
| Subscriptions infra (RevenueCat free tier) | $0 |
| Total to launch | ~$150–350 |
That’s not a hypothetical — it’s the standard path for apps generated as React Native + Expo projects, where auth, database, and screens come out of the generation step instead of a $40,000 development contract. The trade: you do the directing, iterating, and testing yourself. For validation-stage products that’s not a compromise — it’s the correct allocation of a founder’s money.
When paying $50k+ still makes sense
Honesty clause: agencies aren’t obsolete. Pay professionals when you have hardware integrations, regulated data (health, finance) needing compliance sign-off, novel technical cores (custom ML, realtime video), or funding plus deadline pressure where money is cheaper than your time. The 2026 pattern even for these teams: prototype with AI first, hand the working prototype to the agency as the spec. It cuts scoping cost and prevents the classic “$80k for the wrong thing.”
How to cut your app cost regardless of path
- Scope to one core loop. Every screen beyond the essential 4–5 adds cost on every path.
- Write a one-page PRD. Ambiguity is billed hourly. (PRD-to-app template prompts.)
- Use cross-platform output. One React Native codebase ≈ 60–70% of the cost of separate iOS + Android builds.
- Validate before you invest. Build the AI version for ~$150 first; spend the $50k only on what survives contact with users.
