How to work it out

  1. Difference: 51 − 60 = -9
  2. Divide by the starting value: -9 ÷ 60 = -0.15
  3. Multiply by 100: -15%
  4. Check: Work forwards from the start: 60 × (1 − 0.15) = 60 × 0.85 = 51.

In a spreadsheet: =(51-60)/60*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 85% of the old one: for every 100 at the start there are now 85, so 15 out of every 100 have gone.

Sales: a price cut from $60 to $51 is a 15% discount.

Why the change back is different

A 15% fall followed by a 15% rise does not bring you back to 60: it gives 58.65. The second percentage is taken of 51, not of 60, so to undo this change you need 17.6471% instead.
