How to work it out

  1. Difference: 81 − 32 = 49
  2. Divide by the starting value: 49 ÷ 32 = 1.53125
  3. Multiply by 100: 153.125%
  4. Check: Work forwards from the start: 32 × (1 + 1.53125) = 32 × 2.53125 = 81.

In a spreadsheet: =(81-32)/32*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 2.5313 times the old one: for every 100 at the start there are now 253.125. The value has more than doubled.

Prices: an item whose price rises from $32 to $81 has gone up by 153.125%.

Why the change back is different

A 153.125% rise followed by a 153.125% fall does not bring you back to 32: it gives -43.0313. The second percentage is taken of 81, not of 32, so to undo this change you need 60.4938% instead.
