How to work it out

  1. Difference: 23 − 34 = -11
  2. Divide by the starting value: -11 ÷ 34 = -0.323529
  3. Multiply by 100: -32.3529%
  4. Check: Work forwards from the start: 34 × (1 − 0.323529) = 34 × 0.676471 = 23.

In a spreadsheet: =(23-34)/34*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 67.6471% of the old one: for every 100 at the start there are now 67.6471, so 32.3529 out of every 100 have gone.

Sales: a price cut from $34 to $23 is a 32.3529% discount.

Why the change back is different

A 32.3529% fall followed by a 32.3529% rise does not bring you back to 34: it gives 30.4412. The second percentage is taken of 23, not of 34, so to undo this change you need 47.8261% instead.
