How to work it out

  1. Difference: 61 − 70 = -9
  2. Divide by the starting value: -9 ÷ 70 = -0.128571
  3. Multiply by 100: -12.8571%
  4. Check: Work forwards from the start: 70 × (1 − 0.128571) = 70 × 0.871429 = 61.

In a spreadsheet: =(61-70)/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 87.1429% of the old one: for every 100 at the start there are now 87.1429, so 12.8571 out of every 100 have gone.

Sales: a price cut from $70 to $61 is a 12.8571% discount.

Why the change back is different

A 12.8571% fall followed by a 12.8571% rise does not bring you back to 70: it gives 68.8429. The second percentage is taken of 61, not of 70, so to undo this change you need 14.7541% instead.
