How to work it out

  1. Difference: 26 − 18 = 8
  2. Divide by the starting value: 8 ÷ 18 = 0.444444
  3. Multiply by 100: 44.4444%
  4. Check: Work forwards from the start: 18 × (1 + 0.444444) = 18 × 1.444444 = 26.

In a spreadsheet: =(26-18)/18*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 1.4444 times the old one: for every 100 at the start there are now 144.4444.

Prices: an item whose price rises from $18 to $26 has gone up by 44.4444%.

Why the change back is different

A 44.4444% rise followed by a 44.4444% fall does not bring you back to 18: it gives 14.4444. The second percentage is taken of 26, not of 18, so to undo this change you need 30.7692% instead.
