Percentage variance formula

The formula for calculating percentage variance is:

PV = ((NV – OV) / OV) *100


  • PV = Percentage variance
  • NV = New value
  • OV = Old value

How to calculate percentage variance?

Percentage variance is a measure of the relative change between two values.

Here’s a step-by-step guide on how to calculate percentage variance

  1. Determine the old value and new value
  2. Subtract an old value from the new value, difference = new value – old value
  3. Divide the difference by the old value
  4. Last, multiply by 100 to get the percentage variance

Solved Example

Example – The old value is 50 and the new value is 75 then find the percentage variance.


Given, old value = 50, new value = 75

Percentage variance = (75 – 50)/50 = 25/50 *100 = 50%

Therefore, 50% increase from old values to new values.
