How to work it out

  1. Difference: 34 − 43 = -9
  2. Divide by the starting value: -9 ÷ 43 = -0.209302
  3. Multiply by 100: -20.9302%
  4. Check: Work forwards from the start: 43 × (1 − 0.209302) = 43 × 0.790698 = 34.

In a spreadsheet: =(34-43)/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 79.0698% of the old one: for every 100 at the start there are now 79.0698, so 20.9302 out of every 100 have gone.

Sales: a price cut from $43 to $34 is a 20.9302% discount.

Why the change back is different

A 20.9302% fall followed by a 20.9302% rise does not bring you back to 43: it gives 41.1163. The second percentage is taken of 34, not of 43, so to undo this change you need 26.4706% instead.
