How to work it out

  1. Difference: 98 − 31 = 67
  2. Divide by the starting value: 67 ÷ 31 = 2.16129
  3. Multiply by 100: 216.129%
  4. Check: Work forwards from the start: 31 × (1 + 2.16129) = 31 × 3.16129 = 98.

In a spreadsheet: =(98-31)/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 3.1613 times the old one: for every 100 at the start there are now 316.129. The value has more than doubled.

Prices: an item whose price rises from $31 to $98 has gone up by 216.129%.

Why the change back is different

A 216.129% rise followed by a 216.129% fall does not bring you back to 31: it gives -113.8065. The second percentage is taken of 98, not of 31, so to undo this change you need 68.3673% instead.
