About this percentage calculator
A simple percentage calculator for discounts, tax checks, margins, growth, school marks and everyday calculations.
Three common percentage calculations
Use the calculation selector for “A% of B”, “A is what % of B?”, or percentage change from one value to another. These cover common discount, markup, score, growth and comparison calculations without changing the formula manually.
For financial decisions, keep the original values and units consistent—mixing monthly and yearly figures is a common source of incorrect percentage comparisons.
