Frequently asked questions
How do I calculate percentage increase?
Percentage increase = ((New Value - Old Value) / Old Value) × 100. If something went from 100 to 120, the increase is ((120-100)/100) × 100 = 20%. Use Percentage Change mode in the calculator.
How do I find what percentage X is of Y?
Divide X by Y and multiply by 100. 25 is what percentage of 80? (25/80) × 100 = 31.25%. Select 'What percent is X of Y' mode.
How do I calculate a discount?
If an item costs 500 with a 15% discount: 15% of 500 = 75 discount. Final price = 500 - 75 = 425. Use 'Percentage of a number' mode and subtract the result.
