Introduction to Percentage Calculations

Percentages represent fractions out of 100, symbolized by '%'. In retail shopping, tax calculations, business reports, statistics, and interest calculations, percentages are used to compare rates and values. While basic percentages are simple, calculating percentage increases, decreases, and ratios can be confusing. Our online Percentage Calculator does this math instantly.

The Core Math Formulas for Percentages

There are three primary types of percentage calculations: 1. Finding a percentage of a number: Value = (Percentage / 100) * Total. 2. Finding the percentage ratio of a number: Percentage = (Part / Total) * 100. 3. Finding a percentage change (increase or decrease): Change % = [(New Value - Old Value) / Old Value] * 100.
