Small steps and big leaps

What Percent Mate separates from most percentage calculators are the ± stepper buttons. Useful to play around with 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 rates (RoC), response rates (returns, complaints), weight loss/gain, volume discounts, savings goals, ROI, profit vs. cost, tolerances, fees, discounts, rebates, interest, debt, taxes, VAT (Value Added Tax: in both directions) and restaurant tipping.
