About
Reverse Percentage Calculator
This calculator determines the original whole number when you know what a specific percentage of it equals. It performs the inverse operation of percentage calculation to find the base value.
The calculation uses the formula: Number ÷ (Percentage ÷ 100) = Original Value. For example, if 40 represents 20% of an unknown number: 40 ÷ (20 ÷ 100) = 40 ÷ 0.20 = 200.
