Frequently Asked Questions

How do I calculate a percentage of a number?+
Multiply the number by the percentage divided by 100. For example, 25% of 200 = 200 * (25/100) = 50.
How do I calculate percentage change?+
Percentage change = ((new value - old value) / old value) * 100. A change from 80 to 100 is ((100-80)/80) * 100 = a 25% increase.
What's the difference between percentage and percentage points?+
A change from 10% to 15% is a 5 percentage point increase, but a 50% percentage increase. Percentage points measure absolute differences; percentages measure relative change.
