How This Calculator Works

This calculator handles four types of percentage calculations: 1. X% of Y = (X / 100) × Y 2. X is what % of Y = (X / Y) × 100 3. % change from X to Y = ((Y - X) / X) × 100 4. X increased by Y% = X × (1 + Y/100) X decreased by Y% = X × (1 - Y/100) Remember: To convert a percentage to a decimal, divide by 100. To convert a decimal to a percentage, multiply by 100.
