How to work it out

  1. Difference: 73 − 78 = -5
  2. Divide by the starting value: -5 ÷ 78 = -0.064103
  3. Multiply by 100: -6.4103%
  4. Check: Work forwards from the start: 78 × (1 − 0.064103) = 78 × 0.935897 = 73.

In a spreadsheet: =(73-78)/78*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 93.5897% of the old one: for every 100 at the start there are now 93.5897, so 6.4103 out of every 100 have gone.

Sales: a price cut from $78 to $73 is a 6.4103% discount.

Why the change back is different

A 6.4103% fall followed by a 6.4103% rise does not bring you back to 78: it gives 77.6795. The second percentage is taken of 73, not of 78, so to undo this change you need 6.8493% instead.
