How to work it out

  1. Difference: 44 − 40 = 4
  2. Divide by the starting value: 4 ÷ 40 = 0.1
  3. Multiply by 100: 10%
  4. Check: Work forwards from the start: 40 × (1 + 0.1) = 40 × 1.1 = 44.

In a spreadsheet: =(44-40)/40*100. Always divide by the starting value, not the new one. A rise from 40 to 50 is +25%, but the fall from 50 back to 40 is −20%.

What the result means

The new value is 1.1 times the old one: for every 100 at the start there are now 110.

Prices: an item whose price rises from $40 to $44 has gone up by 10%.

Why the change back is different

A 10% rise followed by a 10% fall does not bring you back to 40: it gives 39.6. The second percentage is taken of 44, not of 40, so to undo this change you need 9.0909% instead.
