How to work it out

  1. Difference: 70 − 74 = -4
  2. Divide by the starting value: -4 ÷ 74 = -0.054054
  3. Multiply by 100: -5.4054%
  4. Check: Work forwards from the start: 74 × (1 − 0.054054) = 74 × 0.945946 = 70.

In a spreadsheet: =(70-74)/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 94.5946% of the old one: for every 100 at the start there are now 94.5946, so 5.4054 out of every 100 have gone.

Sales: a price cut from $74 to $70 is a 5.4054% discount.

Why the change back is different

A 5.4054% fall followed by a 5.4054% rise does not bring you back to 74: it gives 73.7838. The second percentage is taken of 70, not of 74, so to undo this change you need 5.7143% instead.
