How to work it out

  1. Difference: 91 − 43 = 48
  2. Divide by the starting value: 48 ÷ 43 = 1.116279
  3. Multiply by 100: 111.6279%
  4. Check: Work forwards from the start: 43 × (1 + 1.116279) = 43 × 2.116279 = 91.

In a spreadsheet: =(91-43)/43*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 2.1163 times the old one: for every 100 at the start there are now 211.6279. The value has more than doubled.

Prices: an item whose price rises from $43 to $91 has gone up by 111.6279%.

Why the change back is different

A 111.6279% rise followed by a 111.6279% fall does not bring you back to 43: it gives -10.5814. The second percentage is taken of 91, not of 43, so to undo this change you need 52.7473% instead.
