How to work it out

  1. Difference: 6 − 51 = -45
  2. Divide by the starting value: -45 ÷ 51 = -0.882353
  3. Multiply by 100: -88.2353%
  4. Check: Work forwards from the start: 51 × (1 − 0.882353) = 51 × 0.117647 = 6.

In a spreadsheet: =(6-51)/51*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 11.7647% of the old one: for every 100 at the start there are now 11.7647, so 88.2353 out of every 100 have gone.

Sales: a price cut from $51 to $6 is a 88.2353% discount.

Why the change back is different

A 88.2353% fall followed by a 88.2353% rise does not bring you back to 51: it gives 11.2941. The second percentage is taken of 6, not of 51, so to undo this change you need 750% instead.
