How to work it out

  1. Difference: 66 − 92 = -26
  2. Divide by the starting value: -26 ÷ 92 = -0.282609
  3. Multiply by 100: -28.2609%
  4. Check: Work forwards from the start: 92 × (1 − 0.282609) = 92 × 0.717391 = 66.

In a spreadsheet: =(66-92)/92*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 71.7391% of the old one: for every 100 at the start there are now 71.7391, so 28.2609 out of every 100 have gone.

Sales: a price cut from $92 to $66 is a 28.2609% discount.

Why the change back is different

A 28.2609% fall followed by a 28.2609% rise does not bring you back to 92: it gives 84.6522. The second percentage is taken of 66, not of 92, so to undo this change you need 39.3939% instead.
