How to work it out

  1. Difference: 88 − 84 = 4
  2. Divide by the starting value: 4 ÷ 84 = 0.047619
  3. Multiply by 100: 4.7619%
  4. Check: Work forwards from the start: 84 × (1 + 0.047619) = 84 × 1.047619 = 88.

In a spreadsheet: =(88-84)/84*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 1.0476 times the old one: for every 100 at the start there are now 104.7619.

Prices: an item whose price rises from $84 to $88 has gone up by 4.7619%.

Why the change back is different

A 4.7619% rise followed by a 4.7619% fall does not bring you back to 84: it gives 83.8095. The second percentage is taken of 88, not of 84, so to undo this change you need 4.5455% instead.
