How to work it out

  1. Difference: 55 − 64 = -9
  2. Divide by the starting value: -9 ÷ 64 = -0.140625
  3. Multiply by 100: -14.0625%
  4. Check: Work forwards from the start: 64 × (1 − 0.140625) = 64 × 0.859375 = 55.

In a spreadsheet: =(55-64)/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 85.9375% of the old one: for every 100 at the start there are now 85.9375, so 14.0625 out of every 100 have gone.

Sales: a price cut from $64 to $55 is a 14.0625% discount.

Why the change back is different

A 14.0625% fall followed by a 14.0625% rise does not bring you back to 64: it gives 62.7344. The second percentage is taken of 55, not of 64, so to undo this change you need 16.3636% instead.
