Not so simple to calculate a percentage direct and reverse especially with his iPhone! SpeedPercent is THE solution!
% Direct:
- I give you x% off
- Your rent will be revalued by x%
- What will be my net salary (payroll deducted).
% Reverse:
- I withdrew € 28 on your purchase:% match?
- What% of charges, which to me is taken from my gross salary?
