How to work it out

  1. Difference: 83 − 43 = 40
  2. Divide by the starting value: 40 ÷ 43 = 0.930233
  3. Multiply by 100: 93.0233%
  4. Check: Work forwards from the start: 43 × (1 + 0.930233) = 43 × 1.930233 = 83.

In a spreadsheet: =(83-43)/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 1.9302 times the old one: for every 100 at the start there are now 193.0233.

Prices: an item whose price rises from $43 to $83 has gone up by 93.0233%.

Why the change back is different

A 93.0233% rise followed by a 93.0233% fall does not bring you back to 43: it gives 5.7907. The second percentage is taken of 83, not of 43, so to undo this change you need 48.1928% instead.
