How to Calculate Percentages
What is X% of Y?
Divide the percentage by 100, then multiply by the number. For example, 15% of 200 = (15 ÷ 100) × 200 = 30.
How to calculate percentage increase
Subtract the old value from the new value, divide by the old value, then multiply by 100. For example, from 50 to 75: ((75-50) ÷ 50) × 100 = 50% increase.
How to calculate percentage difference
Find the absolute difference between two values, divide by their average, then multiply by 100. This gives you a symmetrical comparison.
