Google Ads ROI calculator (lead gen)

Estimate Search ROI using the inputs that matter: spend, CPC, lead rate, close rate, revenue per sale, and margin. Use this to decide whether to scale, fix waste, or revisit tracking.

This is a directional calculator. If tracking is unverified, the outputs are not reliable. Start with the Tracking Troubleshooter.

Deliverable example: Waste Report.

FAQ

Is this a guarantee of ROI?

No. It is a directional estimate based on the inputs you provide.

What if my lead quality is low?

Fix tracking and qualification first; ROI math is only as good as the lead data.

Should I use LTV?

If you have it, yes. For short sales cycles, revenue per sale is enough.

Can I use this for non‑lead gen?

This tool is tuned for lead gen; e‑commerce works differently.
