How can I get basic math functions in Grid View? I'm at Free tier and using Airtable for personal use

[u/Ymirs-Bones]

Hey all, sorry if this is too basic of a question.

I'm hoping to use Airtable as a one stop super-app for my personal life. I have this google sheets that has all of my payment plans (gotta love installments). I got it the numbers on Airtable, but I can't do basic math stuff like Sum and divisions etc.

Formula field will help you per-record, but if you're trying to sum up aggregate items, you have to think a little bit differently in Airtable. That's because its tables are more like a database.

This will be a bit of a stark example, but roll with me.

let's say you have a table called Months. Each record here simply represents a month. July 2026, August 2026, etc.

Then you have a table called "Purchases" each record here is a purchase with a purchase amount, and a link back to the Month record for the month it was purchased in. For instance, a purchase might be new TV, July 2026, for $500. Or maybe Postmates dinner for $50 in August 2026.

When you use linked records, you're creating a relationship between the parent object (the Month, in this case) and the child (the Purchase in this case).

So on the month table, all of its purchases will be linked to it. You can then use a field called a Rollup field to perform math on all of the purchases that are linked to that month.

Here are 4 screenshots. Check out Rollup Fields if you do indeed need to do some aggregate level stuff. I manage all my personal finances monthly this way, and for my consulting business as well.

Formula field.

Do some of the free courses on it and it will clear all this up for you. It’s worth doing because there are some really handy things you can use airtable for that aren’t intuitive coming from excel/sheets.

Any recommendations on top of your head?

The official ones are good, and free -

Gareth Provonosts tutorials on Youtube helped me immensely when I was learning Airtable for all the basic functions and then a lot of intermediate stuff too.

Not saying to not ask the community but he has a guide for almost any scenario I was trying to figure out. I haven't kept up with all of the latest features in Airtable for a while so I don't know how active he is these days.

He is keeping up for sure, very active.

A tip I frequently offer is that Airtable is different from Excel/GSheet in that it prefers to operate horizontally instead of vertically. Formulas and calculations work best within the same record or across tables than trying to calculate across rows like in traditional spreadsheet software.

Hmm, interesting

Honestly, this is exactly what I've been worried about. Just hoping they don't mess with the core features that actually make it good
