How to work it out

  1. Difference: 10 − 70 = -60
  2. Divide by the starting value: -60 ÷ 70 = -0.857143
  3. Multiply by 100: -85.7143%
  4. Check: Work forwards from the start: 70 × (1 − 0.857143) = 70 × 0.142857 = 10.

In a spreadsheet: =(10-70)/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 14.2857% of the old one: for every 100 at the start there are now 14.2857, so 85.7143 out of every 100 have gone.

Sales: a price cut from $70 to $10 is a 85.7143% discount.

Why the change back is different

A 85.7143% fall followed by a 85.7143% rise does not bring you back to 70: it gives 18.5714. The second percentage is taken of 10, not of 70, so to undo this change you need 600% instead.
