- Percentage increase calculator:
Several calculation methods exist, here is one of them:
Marc has a salary of 1000€ and wants to know his new salary with a 12.5% increase. We therefore take 12.5/100 or 0.125 which we multiply by the 1000x0.125 salary. We find an increase of 125€, his new salary will be 1125€.

- Percentage decrease calculator:
Kevin spends 40€ a week on gas and wants to reduce his expenses by 15%. We therefore take the opposite of 15% or 85% and therefore 0.85 (85/100) which we multiply by 40€.
This gives 40 x 0.85 = 34€ (6€ less savings).
