Free tools / App Development Cost Calculator
App Development Cost Calculator
Pick the kind of app, the features it needs and an hourly rate. You get a rough range of hours and cost to hire developers, with the formula shown, next to what building it with Mythex costs.
How the cost calculator works
- Choose the kind of app. Each has a base range of hours for its core screens and logic.
- Tick the features it needs, such as login, payments, an admin panel or phone apps. Each adds its own range of hours.
- Choose a design level and an hourly rate, or type your own rate from quotes you have received.
- The estimate is (base hours + feature hours) × design factor × 1.25 for testing and project management, giving a low and a high number of hours. Cost is low hours × low rate to high hours × high rate.
Read the estimate as a range, not a quote
The hour ranges are our own rough planning figures for a first version built by a competent developer or team, not survey data. Real projects vary with how clear the requirements are, how many rounds of changes you ask for, and what already exists. The rates are examples to edit, not market averages.
Use the result to sanity-check quotes: if a quote is far below the low end, ask what is left out; if it is far above the high end, ask what is included that you did not list.
What the estimate leaves out
Ongoing costs are not included: hosting, the database, email and payment fees, app store accounts, and the developer time to fix bugs and add features after launch. For many apps, the first year of upkeep is a real share of the build cost.
Building with an AI app builder changes the maths: you describe the app and change it yourself, so the cost is your time plus a subscription. It suits first versions and business tools well; very large or regulated systems still benefit from experienced developers.
Questions
How much does it cost to build an app?
It depends mostly on the number of features and who builds it. Use the calculator to see a range for your list of features at the rates you have been quoted. Simple apps built with an AI app builder can cost only a subscription.
Are these estimates accurate?
They are rough planning ranges, deliberately wide, with the formula shown so you can adjust it. Only a developer who has read your requirements can give you a real quote.
What does Mythex cost?
Mythex has a Free plan to start, and Pro is $25 a month, which adds features such as custom domains and turning your app into Android and iPhone apps.
