How to work it out

  1. Difference: 97 − 31 = 66
  2. Divide by the starting value: 66 ÷ 31 = 2.129032
  3. Multiply by 100: 212.9032%
  4. Check: Work forwards from the start: 31 × (1 + 2.129032) = 31 × 3.129032 = 97.

In a spreadsheet: =(97-31)/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 3.129 times the old one: for every 100 at the start there are now 312.9032. The value has more than doubled.

Prices: an item whose price rises from $31 to $97 has gone up by 212.9032%.

Why the change back is different

A 212.9032% rise followed by a 212.9032% fall does not bring you back to 31: it gives -109.5161. The second percentage is taken of 97, not of 31, so to undo this change you need 68.0412% instead.
