How to work it out

  1. Difference: 43 − 18 = 25
  2. Divide by the starting value: 25 ÷ 18 = 1.388889
  3. Multiply by 100: 138.8889%
  4. Check: Work forwards from the start: 18 × (1 + 1.388889) = 18 × 2.388889 = 43.

In a spreadsheet: =(43-18)/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 2.3889 times the old one: for every 100 at the start there are now 238.8889. The value has more than doubled.

Prices: an item whose price rises from $18 to $43 has gone up by 138.8889%.

Why the change back is different

A 138.8889% rise followed by a 138.8889% fall does not bring you back to 18: it gives -16.7222. The second percentage is taken of 43, not of 18, so to undo this change you need 58.1395% instead.
