How to work it out

  1. Difference: 47 − 70 = -23
  2. Divide by the starting value: -23 ÷ 70 = -0.328571
  3. Multiply by 100: -32.8571%
  4. Check: Work forwards from the start: 70 × (1 − 0.328571) = 70 × 0.671429 = 47.

In a spreadsheet: =(47-70)/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 67.1429% of the old one: for every 100 at the start there are now 67.1429, so 32.8571 out of every 100 have gone.

Sales: a price cut from $70 to $47 is a 32.8571% discount.

Why the change back is different

A 32.8571% fall followed by a 32.8571% rise does not bring you back to 70: it gives 62.4429. The second percentage is taken of 47, not of 70, so to undo this change you need 48.9362% instead.
