How to Calculate Percent Increase

  1. Subtract the original value from the new value.
  2. Divide the increase by the original value.
  3. Multiply the result by 100.

Example: a price increases from $80 to $100. The increase is 100 − 80 = 20. The percentage increase is 20 ÷ 80 × 100 = 25%.

Percent Increase Formula

Percentage Increase = ((New Value − Original Value) ÷ Original Value) × 100

Percent Increase Between Two Numbers

When comparing two numbers, the first number is treated as the original (or reference) value, and the second is the new value. The percentage increase tells you how much larger the second number is, expressed as a percentage of the first.

Percent Increase vs Percentage Change

Percent increase specifically describes a positive change — the new value is higher than the original. Percentage change is a broader term that can describe either an increase or a decrease, depending on whether the result is positive or negative.
