How to work it out

  1. Difference: 6 − 7 = -1
  2. Divide by the starting value: -1 ÷ 7 = -0.142857
  3. Multiply by 100: -14.2857%
  4. Check: Work forwards from the start: 7 × (1 − 0.142857) = 7 × 0.857143 = 6.

In a spreadsheet: =(6-7)/7*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 85.7143% of the old one: for every 100 at the start there are now 85.7143, so 14.2857 out of every 100 have gone.

Sales: a price cut from $7 to $6 is a 14.2857% discount.

Why the change back is different

A 14.2857% fall followed by a 14.2857% rise does not bring you back to 7: it gives 6.8571. The second percentage is taken of 6, not of 7, so to undo this change you need 16.6667% instead.
