How to work it out

  1. Difference: 23 − 70 = -47
  2. Divide by the starting value: -47 ÷ 70 = -0.671429
  3. Multiply by 100: -67.1429%
  4. Check: Work forwards from the start: 70 × (1 − 0.671429) = 70 × 0.328571 = 23.

In a spreadsheet: =(23-70)/70*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 32.8571% of the old one: for every 100 at the start there are now 32.8571, so 67.1429 out of every 100 have gone.

Sales: a price cut from $70 to $23 is a 67.1429% discount.

Why the change back is different

A 67.1429% fall followed by a 67.1429% rise does not bring you back to 70: it gives 38.4429. The second percentage is taken of 23, not of 70, so to undo this change you need 204.3478% instead.
