How much does it cost to build an app?
There is no honest single price for "an app". The cost is the number of hours your app needs times the rate of the person or team who builds it. Both numbers depend on decisions you can influence, which is why this calculator shows hours first.
What decides the hours
- Features: accounts, payments, chat or an admin panel each add real work. Chat, offline use and AI features are usually among the larger ones.
- Platform: a web app is one app. A phone app for iOS and Android adds store submission. Phone and browser together means two apps on one backend.
- Connections to other tools: every external service has its own interface, limits and edge cases.
- Design depth: a clean standard design is quicker than custom animations and illustrations.
- Clarity up front: unclear requirements turn into rework. A clear brief is the cheapest way to save hours.
What decides the rate
Rates differ by country, experience and how the work is organised: a freelancer, a small studio or an agency. A higher rate can still be cheaper overall if the developer has shipped the same kind of app before and needs fewer hours. That's why we don't show a default rate: use one from a real offer.
Costs after launch
Plan for hosting, the database, payment fees, app store accounts and ongoing fixes. Our comparisons list the official prices of common services, for example Supabase vs. Firebase and RevenueCat vs. Stripe.
How to get from estimate to quote
Use the range to check whether your idea fits your budget, cut features that can wait, then turn your selection into a brief and ask verified builders for real quotes. Compare offers on the same brief, not on headline prices.
Frequently asked questions
How much does it cost to build an app?
There is no honest single number. The cost is the hours your app needs times the rate of whoever builds it, and both vary a lot. This calculator gives you an hours range for your features and turns it into a cost range at a rate you choose. A quote from a developer replaces it.
Why does the calculator show hours instead of prices?
Hourly rates differ by country, experience and type of developer, so any default price would be a guess. Hours depend on what you build, which is something you know. You enter the rate yourself, for example from an offer you already have.
Are the hour ranges accurate?
They are planning assumptions for one developer working with AI-assisted tools, not measured averages. Every project has its own details, so treat the result as a starting point for a conversation, not as a budget.
What costs come after launch?
Hosting, the database, payment fees, app store accounts and ongoing fixes and updates. Our comparisons list the official prices of common services, for example Supabase, Vercel, Stripe and RevenueCat.
Is a no-code tool cheaper?
If you build it yourself, you mostly pay with your own time instead of a developer's. If you want it built for you, a developer using AI-assisted tools is usually the faster route to a product you own.
