How to work it out

  1. Difference: 10 − 17 = -7
  2. Divide by the starting value: -7 ÷ 17 = -0.411765
  3. Multiply by 100: -41.1765%
  4. Check: Work forwards from the start: 17 × (1 − 0.411765) = 17 × 0.588235 = 10.

In a spreadsheet: =(10-17)/17*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 58.8235% of the old one: for every 100 at the start there are now 58.8235, so 41.1765 out of every 100 have gone.

Sales: a price cut from $17 to $10 is a 41.1765% discount.

Why the change back is different

A 41.1765% fall followed by a 41.1765% rise does not bring you back to 17: it gives 14.1176. The second percentage is taken of 10, not of 17, so to undo this change you need 70% instead.
