How to work it out

  1. Gap between the values: |40 − 60| = 20
  2. Average of the values: (40 + 60) ÷ 2 = 50
  3. Divide the gap by the average and multiply by 100: 20 ÷ 50 × 100 = 40%
  4. Check: Work backwards: 0.4 × 50 = 20, the gap between the values.

In a spreadsheet: =ABS(40-60)/((40+60)/2)*100. Dividing by one of the values instead of their average turns it into a percentage change, which depends on which value you start from.

What the result means

60 is 20 more than 40. Measured against their average, 50, that gap is 40%. The result is the same whichever value you name first.

Prices: if one shop charges $40 and another $60 for the same item, the prices differ by 40%.

Why the average is the base

Dividing the gap of 20 by 40 gives 50%, and dividing it by 60 gives 33.3333%. The average, 50, sits between them, so the result does not depend on which value is listed first.

Questions

Percentage Difference between 40 and 60

The percentage difference between 40 and 60 is 40%: the gap divided by the average. Formula and steps.

What is the percentage change from 40 to 60?

+50%. Percentage change uses the starting value (40) as the base, so it is larger than the percentage difference of 40%.

What is the difference between percentage difference and percentage change?

Percentage change compares a new value with an old one and divides by the old value. Percentage difference compares two values on an equal footing and divides by their average, so the order does not matter.
