Frequently asked questions
How do I calculate percentage of marks?
Divide the marks you obtained by the maximum marks, then multiply by 100. For example, 435 out of 500 is (435 ÷ 500) × 100 = 87%. Use the "Marks → %" tab above to do it instantly.
How do I find what percent one number is of another?
Divide the first number by the second and multiply by 100. The "X is what % of Y" tab does this for you.
How is percentage increase or decrease calculated?
Subtract the old value from the new value, divide by the old value, and multiply by 100. A positive result is an increase; a negative result is a decrease.
