Frequently Asked Questions
How do I calculate a percentage of a number?
Multiply the number by the percentage and divide by 100. For example, 15% of 200 is (200 × 15) ÷ 100 = 30.
How do I find the percentage change?
Subtract the old value from the new value, divide by the old value, and multiply by 100. For example, from 50 to 75: ((75-50)/50) × 100 = 50% increase.
