Percentage Calculator

A percentage is a number expressed as a fraction of 100, represented with the “%” symbol. It is used to show proportions, comparisons and ratios in daily life and mathematics. For example, if you score 80 out of 100 marks, you have achieved 80%. Percentages are widely used in fields like finance, statistics, health, education and business to measure change, distribution, or performance.

Our online percentage calculator is simple and convenient. Just enter any two known values (percentage, base value, or result) and the tool will calculate the missing one instantly. For example, you can calculate how much 20% of 500 is, or find what percentage one number is of another. No registration or downloads are required — it works directly in your browser on any device.

The calculator uses the standard percentage formula:

P × V1 = V2

Where:

• P = Percentage
• V1 = Base Value
• V2 = Result

For example, if Anna earns $2500 and pays $250 in tax, the calculator finds that $250 is 10% of $2500. Instead of solving formulas manually, you simply enter the values and the tool does the math instantly.
