Percent increase
Step-by-step
Difference = New − Original = 150 − 100 = 50
Percent increase = (Difference ÷ Original) × 100
= (50 ÷ 100) × 100
= 50%

Arithmetic
A percent increase calculator computes the percentage by which a value has risen. Enter the original and new values to see the percent increase, absolute difference, and step-by-step work.
Percent increase is calculated as ((new − original) ÷ original) × 100. For example, going from 100 to 150 is ((150 − 100) ÷ 100) × 100 = 50%.
If the new value is smaller than the original, the result is negative, indicating a decrease rather than an increase.
% increase = ((new − original) ÷ original) × 100
Standard percent increase formula.
