How to work it out

  1. Difference: 27 − 83 = -56
  2. Divide by the starting value: -56 ÷ 83 = -0.674699
  3. Multiply by 100: -67.4699%
  4. Check: Work forwards from the start: 83 × (1 − 0.674699) = 83 × 0.325301 = 27.

In a spreadsheet: =(27-83)/83*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 32.5301% of the old one: for every 100 at the start there are now 32.5301, so 67.4699 out of every 100 have gone.

Sales: a price cut from $83 to $27 is a 67.4699% discount.

Why the change back is different

A 67.4699% fall followed by a 67.4699% rise does not bring you back to 83: it gives 45.2169. The second percentage is taken of 27, not of 83, so to undo this change you need 207.4074% instead.
