This is your next percentage calculator app.

## Small steps and big leaps

What Percent Mate separates from most percentage calculators are the ± stepper buttons. Useful to adjust the solution.

Indispensable for What-if Scenario Analysis (WISA).

## Small in size. Great with numbers.

Percent Mate is designed for calculations of (sales) growth rates, climb rate s(RoC), response rates (returns, complaints), weight loss/gain, volume discounts, savings goals, ROI, profit vs. costs, tolerances, fees, discounts, rebates, interest, debt, taxes, VAT (Value Added Tax: in both directions) and restaurant tipping.
