How to work it out

  1. Difference: 93 − 100 = -7
  2. Divide by the starting value: -7 ÷ 100 = -0.07
  3. Multiply by 100: -7%
  4. Check: Work forwards from the start: 100 × (1 − 0.07) = 100 × 0.93 = 93.

In a spreadsheet: =(93-100)/100*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 93% of the old one: for every 100 at the start there are now 93, so 7 out of every 100 have gone.

Sales: a price cut from $100 to $93 is a 7% discount.

Why the change back is different

A 7% fall followed by a 7% rise does not bring you back to 100: it gives 99.51. The second percentage is taken of 93, not of 100, so to undo this change you need 7.5269% instead.
