Percentage Change Formula

Transparent mathematical methodology explained in plain English.

Percentage Change (%) = [(New Value - Initial Value) / |Initial Value|] × 100

Finds relative growth or reduction by dividing absolute difference by initial baseline magnitude and multiplying by 100.

Variables Explained:

  • Initial Value (V1): Starting baseline number.
  • New Value (V2): Final comparison number.
Real Project Example

Change from 120 to 150

Calculating percentage growth.

Sample Project Inputs:
Initial Value (V1):120
New Value (V2):150
Step-by-Step Calculation:
  1. Absolute difference: 150 - 120 = +30.
  2. Relative ratio: 30 / 120 = 0.25.
  3. Percentage change: 0.25 × 100 = +25.00%.
  4. Multiplier: 150 / 120 = 1.25x (125% of baseline).
Calculated Answer:+25.00% increase (+30 absolute difference).

What is the difference between percentage change and percentage difference?

Percentage change compares a final value against an initial starting point (directional growth or drop). Percentage difference compares two values where neither is considered a starting baseline (using their average as the denominator).
