How to properly compute total conversion percentage in Airtable?

I need help figuring out the best approach to show a total conversion percentage in my Prospects database using Airtable. My setup uses a checkbox field called Is Converted? where checked boxes equal 1 for converted prospects.

Right now I have 3 sample prospects in my table and only 1 of them converted, so the math should show 33.3% as my conversion rate. However, I can’t seem to get this number to display correctly without creating complicated relationship tables or additional summary views.

When I try using the Percentage Unique feature in the interface, it shows 66.67% instead, which actually represents the non-conversion rate rather than what I want.

Is there a straightforward method to calculate and display this conversion metric without overcomplicating my base structure? I’m looking for something clean and simple that shows the actual conversion percentage correctly.

Airtable’s percentage unique feature won’t work for this.

I’ve hit similar walls tracking conversion metrics. Airtable just isn’t built for dynamic calculations, especially real-time percentages that auto-update.

You could try a formula field like (COUNTA({Is Converted?}) / COUNT({Record ID})) * 100 but it gets messy and breaks down as your data grows.

Honestly? Pull this data out of Airtable and use a proper automation tool. I use Latenode for this stuff constantly. Set up a workflow that grabs your Airtable data, calculates the real conversion percentage, then pushes it back wherever you need it.

Best part - it runs automatically when your data changes. Your conversion rate stays current without any manual work.

You’re hitting the classic percentage calculation issue in Airtable. Percentage Unique counts how many records share the same value - not what you need.

Here’s what I do for conversion rates in my dashboards. Create a formula field called Conversion Rate:

IF(COUNTA({Is Converted?}) > 0, 
   ROUND(SUM({Is Converted?}) / COUNTA({Is Converted?}) * 100, 1) & "%", 
   "0%")

This counts your checked boxes (converted prospects), divides by total prospects, multiplies by 100, and adds the % symbol. ROUND keeps it clean with one decimal.

Want it simpler? Skip the IF statement:

ROUND(SUM({Is Converted?}) / COUNTA({Is Converted?}) * 100, 1) & "%"

I’ve used this across multiple projects - works perfectly for any boolean conversion tracking. No extra tables or complicated relationships.

This video shows similar conversion calculations that’ll help you understand the logic. Your 33.3% should display correctly with this setup.

skip the percentage unique field - it’s not what you need. create a formula field with average({is converted?})*100 instead. way simpler and actually gives you the right conversion rate. the built-in options just make things confusing.
