Frequently asked questions
How do I calculate a percentage of a number?
Divide the percentage by 100 and multiply by the number. For example, 15% of 640 = 0.15 × 640 = 96.
How do I find what percent one number is of another?
Divide the part by the whole and multiply by 100. For example, 45 is 45 ÷ 60 × 100 = 75% of 60.
How do I calculate percentage increase?
Subtract the old value from the new value, divide by the old value and multiply by 100. From 40 to 50 is (50 − 40) ÷ 40 × 100 = 25% increase.
How do I remove a percentage from a price?
Multiply by (1 − percentage ÷ 100). A 30% discount on ₹1,000 is 1,000 × 0.7 = ₹700.
