How to work it out

  1. Difference: 73 − 43 = 30
  2. Divide by the starting value: 30 ÷ 43 = 0.697674
  3. Multiply by 100: 69.7674%
  4. Check: Work forwards from the start: 43 × (1 + 0.697674) = 43 × 1.697674 = 73.

In a spreadsheet: =(73-43)/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 1.6977 times the old one: for every 100 at the start there are now 169.7674.

Prices: an item whose price rises from $43 to $73 has gone up by 69.7674%.

Why the change back is different

A 69.7674% rise followed by a 69.7674% fall does not bring you back to 43: it gives 22.0698. The second percentage is taken of 73, not of 43, so to undo this change you need 41.0959% instead.
