How to work it out

  1. Difference: 17 − 46 = -29
  2. Divide by the starting value: -29 ÷ 46 = -0.630435
  3. Multiply by 100: -63.0435%
  4. Check: Work forwards from the start: 46 × (1 − 0.630435) = 46 × 0.369565 = 17.

In a spreadsheet: =(17-46)/46*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 36.9565% of the old one: for every 100 at the start there are now 36.9565, so 63.0435 out of every 100 have gone.

Sales: a price cut from $46 to $17 is a 63.0435% discount.

Why the change back is different

A 63.0435% fall followed by a 63.0435% rise does not bring you back to 46: it gives 27.7174. The second percentage is taken of 17, not of 46, so to undo this change you need 170.5882% instead.
