How to work it out

  1. Difference: 26 − 45 = -19
  2. Divide by the starting value: -19 ÷ 45 = -0.422222
  3. Multiply by 100: -42.2222%
  4. Check: Work forwards from the start: 45 × (1 − 0.422222) = 45 × 0.577778 = 26.

In a spreadsheet: =(26-45)/45*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 57.7778% of the old one: for every 100 at the start there are now 57.7778, so 42.2222 out of every 100 have gone.

Sales: a price cut from $45 to $26 is a 42.2222% discount.

Why the change back is different

A 42.2222% fall followed by a 42.2222% rise does not bring you back to 45: it gives 36.9778. The second percentage is taken of 26, not of 45, so to undo this change you need 73.0769% instead.
