I have an Excel spreadsheet and would like to sum the numbers in a column starting at one cell (say, `B5`

) and continuing down to the last number in that column.

I know I could just enter a large ending index, like:

```
SUM(B5:B99999)
```

But ideally I could just say something like:

```
SUM(B5:...)
```

And it would sum from B5 all the way down.

I saw this Superuser question - Excel: is it possible to sum an entire column without setting explicit cell boundaries? - which provides a solution for summing *all* of the numbers in a column via the following formula:

```
SUM(B:B)
```

Problem is, I don't want to sum all of the numbers, just those starting in B5 and down.

Thanks
