How to work it out

  1. Difference: 54 − 64 = -10
  2. Divide by the starting value: -10 ÷ 64 = -0.15625
  3. Multiply by 100: -15.625%
  4. Check: Work forwards from the start: 64 × (1 − 0.15625) = 64 × 0.84375 = 54.

In a spreadsheet: =(54-64)/64*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 84.375% of the old one: for every 100 at the start there are now 84.375, so 15.625 out of every 100 have gone.

Sales: a price cut from $64 to $54 is a 15.625% discount.

Why the change back is different

A 15.625% fall followed by a 15.625% rise does not bring you back to 64: it gives 62.4375. The second percentage is taken of 54, not of 64, so to undo this change you need 18.5185% instead.
