How to work it out

  1. Difference: 43 − 51 = -8
  2. Divide by the starting value: -8 ÷ 51 = -0.156863
  3. Multiply by 100: -15.6863%
  4. Check: Work forwards from the start: 51 × (1 − 0.156863) = 51 × 0.843137 = 43.

In a spreadsheet: =(43-51)/51*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 84.3137% of the old one: for every 100 at the start there are now 84.3137, so 15.6863 out of every 100 have gone.

Sales: a price cut from $51 to $43 is a 15.6863% discount.

Why the change back is different

A 15.6863% fall followed by a 15.6863% rise does not bring you back to 51: it gives 49.7451. The second percentage is taken of 43, not of 51, so to undo this change you need 18.6047% instead.
