How to work it out

  1. Difference: 66 − 56 = 10
  2. Divide by the starting value: 10 ÷ 56 = 0.178571
  3. Multiply by 100: 17.8571%
  4. Check: Work forwards from the start: 56 × (1 + 0.178571) = 56 × 1.178571 = 66.

In a spreadsheet: =(66-56)/56*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 1.1786 times the old one: for every 100 at the start there are now 117.8571.

Prices: an item whose price rises from $56 to $66 has gone up by 17.8571%.

Why the change back is different

A 17.8571% rise followed by a 17.8571% fall does not bring you back to 56: it gives 54.2143. The second percentage is taken of 66, not of 56, so to undo this change you need 15.1515% instead.
