How to work it out

  1. Difference: 79 − 69 = 10
  2. Divide by the starting value: 10 ÷ 69 = 0.144928
  3. Multiply by 100: 14.4928%
  4. Check: Work forwards from the start: 69 × (1 + 0.144928) = 69 × 1.144928 = 79.

In a spreadsheet: =(79-69)/69*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 1.1449 times the old one: for every 100 at the start there are now 114.4928.

Prices: an item whose price rises from $69 to $79 has gone up by 14.4928%.

Why the change back is different

A 14.4928% rise followed by a 14.4928% fall does not bring you back to 69: it gives 67.5507. The second percentage is taken of 79, not of 69, so to undo this change you need 12.6582% instead.
