How to work it out

  1. Difference: 81 − 24 = 57
  2. Divide by the starting value: 57 ÷ 24 = 2.375
  3. Multiply by 100: 237.5%
  4. Check: Work forwards from the start: 24 × (1 + 2.375) = 24 × 3.375 = 81.

In a spreadsheet: =(81-24)/24*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 3.375 times the old one: for every 100 at the start there are now 337.5. The value has more than doubled.

Prices: an item whose price rises from $24 to $81 has gone up by 237.5%.

Why the change back is different

A 237.5% rise followed by a 237.5% fall does not bring you back to 24: it gives -111.375. The second percentage is taken of 81, not of 24, so to undo this change you need 70.3704% instead.
