How to work it out

  1. Difference: 49 − 54 = -5
  2. Divide by the starting value: -5 ÷ 54 = -0.092593
  3. Multiply by 100: -9.2593%
  4. Check: Work forwards from the start: 54 × (1 − 0.092593) = 54 × 0.907407 = 49.

In a spreadsheet: =(49-54)/54*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 90.7407% of the old one: for every 100 at the start there are now 90.7407, so 9.2593 out of every 100 have gone.

Sales: a price cut from $54 to $49 is a 9.2593% discount.

Why the change back is different

A 9.2593% fall followed by a 9.2593% rise does not bring you back to 54: it gives 53.537. The second percentage is taken of 49, not of 54, so to undo this change you need 10.2041% instead.
