How to work it out

  1. Difference: 51 − 97 = -46
  2. Divide by the starting value: -46 ÷ 97 = -0.474227
  3. Multiply by 100: -47.4227%
  4. Check: Work forwards from the start: 97 × (1 − 0.474227) = 97 × 0.525773 = 51.

In a spreadsheet: =(51-97)/97*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 52.5773% of the old one: for every 100 at the start there are now 52.5773, so 47.4227 out of every 100 have gone.

Sales: a price cut from $97 to $51 is a 47.4227% discount.

Why the change back is different

A 47.4227% fall followed by a 47.4227% rise does not bring you back to 97: it gives 75.1856. The second percentage is taken of 51, not of 97, so to undo this change you need 90.1961% instead.
