How to work it out

  1. Difference: 43 − 70 = -27
  2. Divide by the starting value: -27 ÷ 70 = -0.385714
  3. Multiply by 100: -38.5714%
  4. Check: Work forwards from the start: 70 × (1 − 0.385714) = 70 × 0.614286 = 43.

In a spreadsheet: =(43-70)/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 61.4286% of the old one: for every 100 at the start there are now 61.4286, so 38.5714 out of every 100 have gone.

Sales: a price cut from $70 to $43 is a 38.5714% discount.

Why the change back is different

A 38.5714% fall followed by a 38.5714% rise does not bring you back to 70: it gives 59.5857. The second percentage is taken of 43, not of 70, so to undo this change you need 62.7907% instead.
