Frequently asked questions

How do I calculate a percentage of a number?

Divide the percentage by 100 and multiply by the number. 20% of 250 is 0.20 × 250 = 50.

What is the percentage change formula?

Subtract the original value from the new value, divide by the original value, then multiply by 100.

What is the difference between percent and percentage points?

A rise from 4% to 6% is 2 percentage points, but a 50% increase. Percentage points compare rates directly; percentages compare relative size.
