How to work it out

  1. Difference: 81 − 62 = 19
  2. Divide by the starting value: 19 ÷ 62 = 0.306452
  3. Multiply by 100: 30.6452%
  4. Check: Work forwards from the start: 62 × (1 + 0.306452) = 62 × 1.306452 = 81.

In a spreadsheet: =(81-62)/62*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 1.3065 times the old one: for every 100 at the start there are now 130.6452.

Prices: an item whose price rises from $62 to $81 has gone up by 30.6452%.

Why the change back is different

A 30.6452% rise followed by a 30.6452% fall does not bring you back to 62: it gives 56.1774. The second percentage is taken of 81, not of 62, so to undo this change you need 23.4568% instead.
