Calculate percentages, increase, decrease, and difference.
The Multi-Mode Percentage Calculator is a versatile math and business tool designed to solve everyday percentage problems with precision. Supporting five calculation modes: finding the percentage of a value (e.g., what is 15% of 240?), determining what percentage one number is of another (e.g., 45 is what percent of 180?), calculating percentage increase (e.g., salary raises, inflation), calculating percentage decrease (e.g., markdowns, depreciation), and computing relative percentage difference between two values.
Percentage increase is calculated with the formula: Increase (%) = ((New Value - Original Value) / Original Value) × 100.
Percentage change compares a new value to an original baseline (directional), whereas percentage difference compares two numbers relative to their average (non-directional).
