Frequently Asked Questions

15% of 200 = (15/100) × 200 = 30. Use the '% of' mode and enter 15 and 200 to confirm.
What percentage is 45 out of 180?↓
45 ÷ 180 × 100 = 25%. Use the 'X is what % of Y' mode with 45 and 180.
How do I calculate a 20% increase?↓
New value = original × 1.20. Or use the '% change' mode: enter the original value and new value to find the percentage change.
How do I calculate a percentage decrease?↓
% decrease = ((Old − New) / Old) × 100. If sales went from 500 to 400: ((500−400)/500) × 100 = 20% decrease.
