How to work it out

  1. Difference: 78 − 83 = -5
  2. Divide by the starting value: -5 ÷ 83 = -0.060241
  3. Multiply by 100: -6.0241%
  4. Check: Work forwards from the start: 83 × (1 − 0.060241) = 83 × 0.939759 = 78.

In a spreadsheet: =(78-83)/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 93.9759% of the old one: for every 100 at the start there are now 93.9759, so 6.0241 out of every 100 have gone.

Sales: a price cut from $83 to $78 is a 6.0241% discount.

Why the change back is different

A 6.0241% fall followed by a 6.0241% rise does not bring you back to 83: it gives 82.6988. The second percentage is taken of 78, not of 83, so to undo this change you need 6.4103% instead.
