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.

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.
