How to work it out

  1. Difference: 1 − 23 = -22
  2. Divide by the starting value: -22 ÷ 23 = -0.956522
  3. Multiply by 100: -95.6522%
  4. Check: Work forwards from the start: 23 × (1 − 0.956522) = 23 × 0.043478 = 1.

In a spreadsheet: =(1-23)/23*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 4.3478% of the old one: for every 100 at the start there are now 4.3478, so 95.6522 out of every 100 have gone.

Sales: a price cut from $23 to $1 is a 95.6522% discount.

Why the change back is different

A 95.6522% fall followed by a 95.6522% rise does not bring you back to 23: it gives 1.9565. The second percentage is taken of 1, not of 23, so to undo this change you need 2,200% instead.
