How to work it out

  1. Difference: 56 − 31 = 25
  2. Divide by the starting value: 25 ÷ 31 = 0.806452
  3. Multiply by 100: 80.6452%
  4. Check: Work forwards from the start: 31 × (1 + 0.806452) = 31 × 1.806452 = 56.

In a spreadsheet: =(56-31)/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 1.8065 times the old one: for every 100 at the start there are now 180.6452.

Prices: an item whose price rises from $31 to $56 has gone up by 80.6452%.

Why the change back is different

A 80.6452% rise followed by a 80.6452% fall does not bring you back to 31: it gives 10.8387. The second percentage is taken of 56, not of 31, so to undo this change you need 44.6429% instead.
