Calculator
1. What you actually received
2. What each ad platform says it drove (same dates)
The figures filled in are an example. Replace them with yours; the result updates as you type and nothing leaves your browser.
At least $4,400 of what they report (31% of the total) never reached your account. They claim 1.4x the revenue you actually made. And that's the minimum: some of your $9,800 probably came from search, email or word of mouth, which no ad platform should be claiming.
| Platform | Spend | Claims | Return they report |
|---|---|---|---|
| Meta Ads | $2,100 | $8,600 | 4.1x |
| Google Ads | $1,500 | $5,600 | 3.7x |
| Your payment records | $3,600 | $9,800 | 2.7x |
The last row divides all the revenue you received by all your ad spend. Because it includes sales that didn't come from ads, your true return from ads is at or below 2.7x.
See which platform actually drove each sale
Attriboo matches every Stripe, Shopify, Paddle or PayPal payment to the visit that came before it, and puts your Meta, Google, TikTok and Microsoft spend next to that revenue. Start free with 5,000 events a month; paid plans start at $5 a month.
Sound familiar?
Every platform claims the sale
A buyer who clicked a Google ad and saw a Meta ad can be counted by both. Neither platform can see the other.
The totals beat your bank balance
Add the platform reports together and they often come to more than Stripe or Shopify actually received.
Refunds stay in the ad report
A refunded sale usually keeps its credit unless you send the refund back to each platform.
How to use it
Pull your real revenue
Take revenue after refunds for one date range from Stripe, Shopify or your payment provider.
Copy each platform's claim
Use the purchase conversion value for the same dates from each ad account. Add spend to compare returns.
Read the gap
Judge spend by revenue per ad dollar, which double counting can't inflate, instead of each platform's own ROAS.
Totals can show that platforms over-claim, but not which sales each one really drove. Attriboo's revenue attribution credits each real payment to the source that brought the buyer, so the numbers never add up to more than you made.

Common questions
Why do ad platforms report more sales than I made?
Each platform counts a sale when the buyer interacted with one of its ads within its own attribution window, and it can't see the other platforms. A buyer who clicked a Google ad and saw a Meta ad can be counted by both. Platforms may also credit sales after a view rather than a click, and add modeled conversions they estimate rather than observe. The guide to ad platform revenue discrepancies walks through each cause with the platforms' own documentation.
Where do I find the numbers to enter?
For revenue, use your payment provider's report for the same dates, after refunds: Stripe's Payments or Revenue report, or Shopify's Sales report. For each platform, use the purchase conversion value column in Ads Manager, Google Ads, TikTok Ads Manager or Microsoft Advertising, with the same date range and currency.
If the platforms claim less than my revenue, are their numbers right?
Not necessarily. Two platforms can both claim the same buyer while other sales go unclaimed, and the totals can still look reasonable. The only way to know which platform drove a sale is to match each payment to the visit that came before it.
What is revenue per ad dollar?
It divides all the revenue you received by all your ad spend. Some people call it MER, the marketing efficiency ratio. Because it includes sales that didn't come from ads, your true return from ads is at or below this number. It can't be inflated by double counting, which is why it's a useful check on the return each platform reports. The ROAS vs ROI guide explains when to add margin and other costs.
Are my numbers sent anywhere?
No. The calculator runs in your browser. Nothing you type is sent to Attriboo or stored.
See which platform actually drove each sale.
Attriboo matches every Stripe, Shopify, Paddle or PayPal payment to the visit before it, and puts your Meta, Google, TikTok and Microsoft spend next to that revenue.
