Question: how to calculate percentage weight in excel?
Answer: Type your first weight in cell A2. Every week when you weigh yourself, enter that weight in the cell in row 2 under the date of the weigh-in. Enter the formula =(B2-A2)/ABS(A2) _-1 in cell B3. This formula tells Excel that you want to make the difference between cells B2 and A2 a percentage.
