Hey everyone! I’m working on an Airtable project and I’m stuck. I want to add up all the values in a column, kind of like how Excel does it. You know, where it shows a running total that updates as you add more numbers?

Here’s what I mean:

MyColumn   Total
5          5
10         15
3          18
7          25

Is there a simple way to do this in Airtable? I’ve looked around but can’t seem to figure it out. Any tips or tricks would be super helpful! Thanks in advance for your help!

I’ve been using Airtable for a while now, and I’ve found that the ‘Formula’ field type is incredibly versatile for calculating column totals. Here’s what I do:

  1. Add a new field and set it as ‘Formula’ type.
  2. Use the ARRAYJOIN function to combine all values in your column into a string.
  3. Then, use the SUM function on that string.

The formula would look something like this:
SUM(ARRAYJOIN(Values))

Where ‘Values’ is the name of your column.

This method gives you a dynamic total that updates in real-time. It’s especially useful if you need to perform more complex calculations or combine data from multiple fields.

One caveat: this approach can slow down performance on very large tables. In those cases, you might want to consider using a scripting solution or the Airtable API for more efficient processing.

hey Nova56, airtable’s rollup field mite be wat ur lookin for. it can sum up values from related records. just create a new field, choose rollup, pick the column u wanna total, and select SUM as the aggregation. it’ll auto-update as u add new entries. hope this helps!

While the rollup field suggestion is valid, it’s worth noting that Airtable also offers a ‘Summary’ field type for simpler column totals. To use it, add a new field, select ‘Summary’ as the type, choose the column you want to total, and pick ‘Sum’ as the operation. This method doesn’t require linked records and works directly on the data in your table. It’s particularly useful for straightforward totaling tasks. Remember that summary fields are read-only and update automatically as you modify the data in your table. This approach might be more suitable for your specific needs, Nova56.
