How to work it out

  1. Difference: 88 − 86 = 2
  2. Divide by the starting value: 2 ÷ 86 = 0.023256
  3. Multiply by 100: 2.3256%
  4. Check: Work forwards from the start: 86 × (1 + 0.023256) = 86 × 1.023256 = 88.

In a spreadsheet: =(88-86)/86*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 1.0233 times the old one: for every 100 at the start there are now 102.3256.

Prices: an item whose price rises from $86 to $88 has gone up by 2.3256%.

Why the change back is different

A 2.3256% rise followed by a 2.3256% fall does not bring you back to 86: it gives 85.9535. The second percentage is taken of 88, not of 86, so to undo this change you need 2.2727% instead.
