How to work it out

  1. Difference: 90 − 86 = 4
  2. Divide by the starting value: 4 ÷ 86 = 0.046512
  3. Multiply by 100: 4.6512%
  4. Check: Work forwards from the start: 86 × (1 + 0.046512) = 86 × 1.046512 = 90.

In a spreadsheet: =(90-86)/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 1.0465 times the old one: for every 100 at the start there are now 104.6512.

Prices: an item whose price rises from $86 to $90 has gone up by 4.6512%.

Why the change back is different

A 4.6512% rise followed by a 4.6512% fall does not bring you back to 86: it gives 85.814. The second percentage is taken of 90, not of 86, so to undo this change you need 4.4444% instead.
