App Development Cost Calculator

Work out app development cost instantly with clear inputs, formula shown and shareable results.

About App Development Cost Calculator

The first platform costs full price and each additional native platform adds roughly 60% more, since business logic and design are reused but UI code is not. That 60% figure is the real argument for cross-platform frameworks: a second native platform never costs the full amount again, but it is far from free.

Formula

Total hours

hours = screens x hours per screen x (1 + 0.6 x (platforms - 1))

Worked example

With the default values below, App Development Cost Calculator returns Total development cost of $26,880.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the App Development Cost figure worked out?

hours = screens x hours per screen x (1 + 0.6 x (platforms - 1)). The first platform costs full price and each additional native platform adds roughly 60% more, since business logic and design are reused but UI code is not.

Why does this matter?

That 60% figure is the real argument for cross-platform frameworks: a second native platform never costs the full amount again, but it is far from free.

What do I need to enter?

Enter screens in the app, hours per screen, blended hourly rate, native platforms to build. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
