How to work it out

  1. Difference: 78 − 70 = 8
  2. Divide by the starting value: 8 ÷ 70 = 0.114286
  3. Multiply by 100: 11.4286%
  4. Check: Work forwards from the start: 70 × (1 + 0.114286) = 70 × 1.114286 = 78.

In a spreadsheet: =(78-70)/70*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 1.1143 times the old one: for every 100 at the start there are now 111.4286.

Prices: an item whose price rises from $70 to $78 has gone up by 11.4286%.

Why the change back is different

A 11.4286% rise followed by a 11.4286% fall does not bring you back to 70: it gives 69.0857. The second percentage is taken of 78, not of 70, so to undo this change you need 10.2564% instead.
