How to work it out

  1. Difference: 4 − 71 = -67
  2. Divide by the starting value: -67 ÷ 71 = -0.943662
  3. Multiply by 100: -94.3662%
  4. Check: Work forwards from the start: 71 × (1 − 0.943662) = 71 × 0.056338 = 4.

In a spreadsheet: =(4-71)/71*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 5.6338% of the old one: for every 100 at the start there are now 5.6338, so 94.3662 out of every 100 have gone.

Sales: a price cut from $71 to $4 is a 94.3662% discount.

Why the change back is different

A 94.3662% fall followed by a 94.3662% rise does not bring you back to 71: it gives 7.7746. The second percentage is taken of 4, not of 71, so to undo this change you need 1,675% instead.
