Handle the common percentage questions without mental math

This page covers the basic percentage cases people hit constantly: finding a percentage of a number, figuring out what percent one number is of another, and seeing what is left after that percentage is removed.

If you want to find a percentage of a number

PercentThe percentage rate you want to apply, such as 15 for 15%.

ValueThe full number you want to take the percentage from.

If the percent is unknown

Use these two fields to answer: part is what percent of the whole?

PartThe smaller amount you are comparing.

Base numberThe whole amount that the part should be compared against.

Useful examples

A strong first math page because the use case is constant

Percentage math shows up in discounts, tips, grades, budgets, reporting, and sales copy. It is one of the most common calculator intents that is still worth serving with a clean, no-nonsense page.
