How to work it out

  1. Difference: 61 − 31 = 30
  2. Divide by the starting value: 30 ÷ 31 = 0.967742
  3. Multiply by 100: 96.7742%
  4. Check: Work forwards from the start: 31 × (1 + 0.967742) = 31 × 1.967742 = 61.

In a spreadsheet: =(61-31)/31*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 1.9677 times the old one: for every 100 at the start there are now 196.7742.

Prices: an item whose price rises from $31 to $61 has gone up by 96.7742%.

Why the change back is different

A 96.7742% rise followed by a 96.7742% fall does not bring you back to 31: it gives 1.9677. The second percentage is taken of 61, not of 31, so to undo this change you need 49.1803% instead.
