How to work it out

  1. Difference: 51 − 93 = -42
  2. Divide by the starting value: -42 ÷ 93 = -0.451613
  3. Multiply by 100: -45.1613%
  4. Check: Work forwards from the start: 93 × (1 − 0.451613) = 93 × 0.548387 = 51.

In a spreadsheet: =(51-93)/93*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 54.8387% of the old one: for every 100 at the start there are now 54.8387, so 45.1613 out of every 100 have gone.

Sales: a price cut from $93 to $51 is a 45.1613% discount.

Why the change back is different

A 45.1613% fall followed by a 45.1613% rise does not bring you back to 93: it gives 74.0323. The second percentage is taken of 51, not of 93, so to undo this change you need 82.3529% instead.
