Result = (X ÷ 100) × YResult = (X ÷ Y) × 100((New − Old) ÷ |Old|) × 100Result = (X × Y) ÷ 100Each tab helps you figure out a percentage differently — from finding percent of two numbers to computing percentage increase online. Here's how each one works and when to use it.
Enter the percentage and the total amount. The calculator multiplies the number by the percentage rate to give you the exact value. Use this to find a discount amount, tax value, or any portion of a number.
Result = (X ÷ 100) × YEnter the partial value (X) and the total (Y) to work out the percentage of two numbers. Divides X by Y and multiplies by 100. Perfect for test score percentages, market share, or how much of a goal you've hit.
Result = (X ÷ Y) × 100Enter the original value and the new value to compute the percentage change. A positive result means an increase; negative means a decrease. The equation for percentage change is shown with every result. Useful for price changes, salary growth, or comparing any two stats.
((New − Old) ÷ |Old|) × 100Enter two percentage values to figure out a percentage of a percentage. The tool multiplies them and divides by 100. Useful for compound discounts — for example, 20% of a 50% discount equals 10%.
(X × Y) ÷ 100Enter the base number and the percentage, then choose to add or take out the percentage. Use "Add %" for price after tax or tip. Use "Take Out %" to find the pre-discount price or work out a percentage of a number in reverse.
