How to work it out

  1. Difference: 60 − 90 = -30
  2. Divide by the starting value: -30 ÷ 90 = -0.333333
  3. Multiply by 100: -33.3333%
  4. Check: Work forwards from the start: 90 × (1 − 0.333333) = 90 × 0.666667 = 60.

In a spreadsheet: =(60-90)/90*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 66.6667% of the old one: for every 100 at the start there are now 66.6667, so 33.3333 out of every 100 have gone.

Sales: a price cut from $90 to $60 is a 33.3333% discount.

Why the change back is different

A 33.3333% fall followed by a 33.3333% rise does not bring you back to 90: it gives 80. The second percentage is taken of 60, not of 90, so to undo this change you need 50% instead.
