The result is the sum of all numbers in row 5. As new data is added to the table, the formula will continue to return a correct total.

### Full row references

Excel supports full row references like this: You can see how this works yourself by typing 1:1 or 3:3 into the name box (left of the formula bar) and hitting return. You will see Excel select the entire row.

### Example

To solve the problem in the example worksheet, we can use a full row reference to row 5 with the SUM function like this: The result is the sum of all numeric values in row 5. As the formula is copied down, we get a sum for row 6 and row 7 as well: As new entries for “Red” are added to the table in rows 5, 6, and 7, the formula will automatically include these new amounts.

### Advantages and risks

The main advantage to full row references is simplicity. Simple and very compact, a full row reference will automatically include all data in a row, even when data is added or removed. However, full row references come with certain risks. One risk is that you may accidentally include extra data in a calculation. For example, if you use =SUM(5:5) to sum numbers in row 5, you are targeting over 16,000 cells to the right. If row 5 includes extra dates somewhere far to the right, the numeric values of these dates will be included, and SUM will return an incorrect result.
