How much does it cost to build an app?
This app development cost calculator turns three numbers β development hours, hourly rate and a design/QA percentage β into a fast estimate of what building your app will cost. Cost is driven mostly by scope: the more screens, features and integrations an app has, the more hours it takes, and hours multiplied by your rate are the bulk of any app budget. Design and QA then add a meaningful slice on top, which is why we let you layer them in as a percentage rather than guess a flat figure.
Treat the result as a planning ballpark, not a fixed quote. Real projects shift with platform (iOS, Android or both), backend complexity, third-party services and how much changes mid-build. A simple app might land in a few hundred hours, while a complex, multi-platform product runs into the thousands. Use this calculator to sanity-check a quote or set an early budget, then refine the hours and rate as your scope firms up.
