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.

Frequently asked questions

How does this app development cost calculator work?
It multiplies your development hours by your hourly rate to get the development cost, then adds design and QA as a percentage on top. For example, 800 hours Γ— $60 = $48,000, plus 20% design/QA = $57,600 total. Everything updates instantly as you change the inputs.
How much does it cost to build an app?
It depends almost entirely on scope. A simple app can take a few hundred hours, while a complex, multi-platform product runs into the thousands. Multiply your realistic hours by your rate, add design and QA, and you have a workable ballpark to plan around.
What is a typical hourly rate for app development?
Rates vary widely by region and seniority β€” from around $25–50/hour for some freelancers to $100–200+/hour for senior developers and agencies in high-cost markets. Use the rate you actually expect to pay rather than a global average for a more accurate estimate.
Why add design and QA as a percentage?
Design and quality assurance scale roughly with the size of the build, so expressing them as a percentage of development cost is a simple, reliable way to estimate them. 15–30% is a common range; increase it for design-heavy apps and lower it for simpler internal tools.
