How much does it cost to develop a mobile game app?
The honest answer is a range, because scope drives everything: art style, multiplayer, backend depth and platform count each move the number more than the genre label does. Based on the quotes our readers shared over the past year, these are realistic brackets for working with an established studio.
| Complexity | Typical cost | Timeline | What you get |
|---|---|---|---|
| Simple | £20,000 – £60,000 | 2–4 months | Hyper-casual or puzzle game, 2D art, single platform, ad monetisation |
| Mid-level | £60,000 – £200,000 | 4–8 months | Casual or arcade title, cross-platform, backend, IAP economy, analytics |
| Complex | £200,000+ | 9–18 months | 3D or multiplayer game, LiveOps tooling, seasons, custom server infrastructure |
Budget a further 15–25% of the build cost per year for post-launch support and content — every studio in our top 5 offers it as a separate retainer.
