How to work it out

  1. Difference: 3 − 100 = -97
  2. Divide by the starting value: -97 ÷ 100 = -0.97
  3. Multiply by 100: -97%
  4. Check: Work forwards from the start: 100 × (1 − 0.97) = 100 × 0.03 = 3.

In a spreadsheet: =(3-100)/100*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 3% of the old one: for every 100 at the start there are now 3, so 97 out of every 100 have gone.

Sales: a price cut from $100 to $3 is a 97% discount.

Why the change back is different

A 97% fall followed by a 97% rise does not bring you back to 100: it gives 5.91. The second percentage is taken of 3, not of 100, so to undo this change you need 3,233.3333% instead.
