You open your Google Ads campaigns table looking for return on ad spend, and no column has that name. Or you open Meta Ads Manager and find a ROAS that looks great but doesn't match what landed in your bank account. Either way you're stuck with a number you can't find or can't trust. This page covers where each platform keeps it, why it sometimes shows up blank, and how to check it against your own sales records.
What you're actually looking for
ROAS is the revenue your ads brought in divided by what you spent on them. The platforms don't measure revenue themselves. They report whatever conversion value your website or tracking sends back to them. If nothing sends a value, the column is empty or shows zero, even when the ads are working fine. That is why most "I can't find it" problems turn out to be tracking problems.
Where each platform keeps the number
| Where you look | What it's called | Where to find it |
|---|---|---|
| Google Ads | Conv. value / cost | Campaigns view, then Columns, then Modify columns, then Conversions. Tick it and save. |
| Meta Ads Manager | Purchase ROAS (return on ad spend) | Columns dropdown, then Performance and Clicks or Customize columns. It only appears if purchase values are being reported. |
| Google Analytics 4 | No single ROAS column | Compare purchase revenue for your ad traffic with the cost imported from a linked ad account, or divide the two yourself. |
| Your own spreadsheet | Revenue from ad customers ÷ ad spend | Sales records for the period, filtered to customers who came from ads, divided by the platform's spend figure. |
If the column is there but empty
A blank or zero ROAS almost always means the ad account has been told a conversion happened but not what it was worth. That's common for service businesses, where the sale closes by phone or in person. It also happens when a form or checkout page was rebuilt and the tag stopped sending the amount. Open your conversion settings and look at whether each action has a value attached, and whether it has recorded anything recently. If a conversion has no value, add a reasonable average job or order value as a stand-in, and note that you did.
If the number looks too good
Meta and Google each count credit their own way, and both can claim the same sale. The attribution window matters, and so does whether a view of the ad counts or only a click. Some Google Ads columns count every conversion action, including low-value ones like a page view or a button press. Before you celebrate a strong ROAS, check which conversion actions feed it and whether they're all real purchases or booked jobs.
A sanity check you can do in a spreadsheet
Pick a recent month. Add up the revenue from customers you can trace to ads, using invoices, a CRM, or the "how did you hear about us" answer. Divide by what the platforms say you spent. Set that beside the ROAS the dashboard reports. They won't match exactly, and they don't need to. If the dashboard is far above your own figure, its credit is too generous. If it is far below, some sales aren't being tracked. Both tell you what to fix before you change any budget.
Why this question rises and falls
Across the 3 distinct queries that make up this topic, people search about 1340 times a month combined. The phrase "how to find roas" itself peaked at 2900 a month in September 2025 and dropped to 480 a month by July 2026. That swing suggests owners look this up in bursts, most likely when they review results and plan budgets. Advertisers bid as much as $27.47 for the top spot on related searches, so you'll see plenty of tool and agency pages ranking above plain explanations. Treat those as one option, not the answer.
What ROAS can't tell you
ROAS is revenue, not profit. A strong figure on a low-margin product can still lose money once costs are counted, and a modest figure on a high-margin service can be very profitable. Work out your break-even ROAS from your margin before you decide whether a number is good or bad. Our guide on calculating ROAS without fooling yourself walks through that step.
A plan for this week
Start by adding the ROAS column in each platform you use. Then open the conversion settings and confirm every real sale or booked job sends a value. Run the spreadsheet check for last month and write down the gap between the dashboard and your own records. Only after that should you change any budgets. If the gap stays large or you can't see why, that is the point where a tracking review is worth considering.
When an outside review makes sense
You can do all of the above yourself, and for a small account it is often enough. An outside team helps most when the sale happens offline, when several platforms claim the same customers, or when values keep disappearing after site changes. In those cases a tracking audit tells you which numbers to trust, and you can ask for it without signing up to ongoing management.
