How to work it out

  1. Difference: 86 − 61 = 25
  2. Divide by the starting value: 25 ÷ 61 = 0.409836
  3. Multiply by 100: 40.9836%
  4. Check: Work forwards from the start: 61 × (1 + 0.409836) = 61 × 1.409836 = 86.

In a spreadsheet: =(86-61)/61*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 1.4098 times the old one: for every 100 at the start there are now 140.9836.

Prices: an item whose price rises from $61 to $86 has gone up by 40.9836%.

Why the change back is different

A 40.9836% rise followed by a 40.9836% fall does not bring you back to 61: it gives 50.7541. The second percentage is taken of 86, not of 61, so to undo this change you need 29.0698% instead.
