How to work it out

  1. Difference: 24 − 51 = -27
  2. Divide by the starting value: -27 ÷ 51 = -0.529412
  3. Multiply by 100: -52.9412%
  4. Check: Work forwards from the start: 51 × (1 − 0.529412) = 51 × 0.470588 = 24.

In a spreadsheet: =(24-51)/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 47.0588% of the old one: for every 100 at the start there are now 47.0588, so 52.9412 out of every 100 have gone.

Sales: a price cut from $51 to $24 is a 52.9412% discount.

Why the change back is different

A 52.9412% fall followed by a 52.9412% rise does not bring you back to 51: it gives 36.7059. The second percentage is taken of 24, not of 51, so to undo this change you need 112.5% instead.
