Frequently Asked Questions

Have a question? We’ve got answers to the most common questions about using our tools.

What is a percentage?+

A percentage is a fraction out of 100. For example, 25% means 25 out of 100, or 0.25 as a decimal. Percentages help compare quantities of different sizes.

How do I calculate a percentage of a value?+

Multiply the value by the percentage and divide by 100. For example, 25% of 80 = (80 × 25) ÷ 100 = 20. This tool does this automatically.

What does percentage increase mean?+

Percentage increase shows how much a value has grown as a percentage of the original value. For example, if a price went from 100 to 120, that is a 20% increase.

Is percentage increase the same as percentage decrease?+

No. A 20% increase followed by a 20% decrease does not return you to the original value. 100 -> 120 (20% increase) -> 96 (20% decrease from 120) = net 4% decrease.

How can I use this tool in real life?+

Calculate discounts on shopping, find what percentage a score represents, determine salary increases, calculate tip percentages, measure growth rates, and much more.
