Conversion Value & ROI Calculator
Explore revenue and ROAS scenarios by changing conversion volume while keeping spend and average value fixed. This is arithmetic, not a forecast.
Why Conversion Value Matters for Smart Bidding
Google's Smart Bidding strategies (Target ROAS, Maximize Conversion Value) work best when they have accurate conversion value data. Without offline revenue data, these algorithms optimize for whatever conversions you're tracking — usually form fills, phone calls, or page views.
The problem: a $200 drain clearing and a $12,000 HVAC installation look identical to Google if you're only tracking "form submitted." With offline conversion values, Google learns which keywords, audiences, and placements generate the highest revenue — and bids accordingly.
The Offline Conversion Value Chain
- Click → Customer clicks your ad ($X cost per click)
- Lead → Customer calls or fills out a form (Google sees this)
- Sale → Customer books a $4,500 job (Google does NOT see this)
- Upload → You send the $4,500 value back to Google Ads
- Optimize → Smart Bidding learns: "Clicks like this generate $4,500. Find more."
What changes when the invoice is on the row
Smart Bidding can prefer the clicks that looked like the $4,500 job and spend less on the clicks that only produced a form. Google measured an average 26% increase in incremental ROAS for Search campaigns bidding to conversion value, among advertisers who connected offline and app data to Data Manager, from April 2025 through April 2026. That figure is Google's average for that setup. Use the slider to try a number and see the arithmetic, then judge the real change on your own spend and your own uploaded revenue.

Frequently Asked Questions
When you upload the booked job, with the invoice amount, Smart Bidding can tell a $4,500 replacement from a form fill. Google measured an average 26% increase in incremental ROAS for Search campaigns bidding to conversion value, among advertisers who connected offline and app data to Data Manager, from April 2025 through April 2026. That is Google's average for that setup, not a forecast for your account. The slider below is a what-if you set yourself.
Use the actual revenue generated from the conversion. For service businesses: the invoice amount for the completed job. For SaaS: the contract value. For e-commerce: the order total. If you don't know the exact value, use your average ticket size as a starting point.
The calculator multiplies the numbers you type by the improvement you choose on the slider. It is arithmetic, not a forecast. Google has not published an improvement you should type in.
Yes. When using Fusion Relays, The Upload Offline Conversions App automatically pulls the actual revenue value from your CRM or field service management tool (like ServiceTitan or Jobber) and sends it alongside the GCLID to Google Ads. No manual value entry required.
