How to work it out

  1. Difference: 61 − 28 = 33
  2. Divide by the starting value: 33 ÷ 28 = 1.178571
  3. Multiply by 100: 117.8571%
  4. Check: Work forwards from the start: 28 × (1 + 1.178571) = 28 × 2.178571 = 61.

In a spreadsheet: =(61-28)/28*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 2.1786 times the old one: for every 100 at the start there are now 217.8571. The value has more than doubled.

Prices: an item whose price rises from $28 to $61 has gone up by 117.8571%.

Why the change back is different

A 117.8571% rise followed by a 117.8571% fall does not bring you back to 28: it gives -10.8929. The second percentage is taken of 61, not of 28, so to undo this change you need 54.0984% instead.
