How to work it out

  1. Difference: 66 − 57 = 9
  2. Divide by the starting value: 9 ÷ 57 = 0.157895
  3. Multiply by 100: 15.7895%
  4. Check: Work forwards from the start: 57 × (1 + 0.157895) = 57 × 1.157895 = 66.

In a spreadsheet: =(66-57)/57*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 1.1579 times the old one: for every 100 at the start there are now 115.7895.

Prices: an item whose price rises from $57 to $66 has gone up by 15.7895%.

Why the change back is different

A 15.7895% rise followed by a 15.7895% fall does not bring you back to 57: it gives 55.5789. The second percentage is taken of 66, not of 57, so to undo this change you need 13.6364% instead.
