How to work it out

  1. Difference: 71 − 74 = -3
  2. Divide by the starting value: -3 ÷ 74 = -0.040541
  3. Multiply by 100: -4.0541%
  4. Check: Work forwards from the start: 74 × (1 − 0.040541) = 74 × 0.959459 = 71.

In a spreadsheet: =(71-74)/74*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 95.9459% of the old one: for every 100 at the start there are now 95.9459, so 4.0541 out of every 100 have gone.

Sales: a price cut from $74 to $71 is a 4.0541% discount.

Why the change back is different

A 4.0541% fall followed by a 4.0541% rise does not bring you back to 74: it gives 73.8784. The second percentage is taken of 71, not of 74, so to undo this change you need 4.2254% instead.
