How to work it out

  1. Difference: 6 − 64 = -58
  2. Divide by the starting value: -58 ÷ 64 = -0.90625
  3. Multiply by 100: -90.625%
  4. Check: Work forwards from the start: 64 × (1 − 0.90625) = 64 × 0.09375 = 6.

In a spreadsheet: =(6-64)/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 9.375% of the old one: for every 100 at the start there are now 9.375, so 90.625 out of every 100 have gone.

Sales: a price cut from $64 to $6 is a 90.625% discount.

Why the change back is different

A 90.625% fall followed by a 90.625% rise does not bring you back to 64: it gives 11.4375. The second percentage is taken of 6, not of 64, so to undo this change you need 966.6667% instead.
