Lead Value Calculator
Lead value is close rate times average customer value. It is what a lead is worth before you buy more of them. Without it, CPA has no ceiling.
The tool
Try it here
Use this before you raise lead-gen spend, and before you set a target CPA. Use a conservative customer value if LTV (lifetime value) is still a guess.
Why it helps
Why you need a Lead Value Calculator
Lead value ≈ (customers ÷ leads) × value per customer. First-order revenue is honest if you do not have LTV yet. Say so.
A high CPA can still be fine if close rate and value are high. A tiny CPA on junk leads is not.
Do not use best-case close rate from one good month. Use a trailing cohort.
When
When to use it
- Setting target CPA in Google Ads or a lead-buy contract.
- When two sources have different close rates and you need a fair CPA cap.
- When finance asks what a demo is worth.
How
How to use it
- 1Enter close rate (or customers and leads) and average customer value.
- 2Lead value = close rate × customer value.
- 3Compare to CPA for that source. If CPA is above lead value, stop scaling.
- 4If you have real LTV, use that as customer value. Do not multiply hope by 12 months.
Example
Example: value of an Acme demo lead
Close rate 20% from the lead conversion example. Average first-year value ₹40,000. Campaign google-in-demo-exact-2026q3.
You put in
- Close rate
- 20%
- Customer value
- ₹40,000
- Current CPA
- ₹2,000
You get
Lead value = 0.20 × 40000 = ₹8,000 CPA ₹2,000 is under ₹8,000 - room on ads-only math.
₹8,000 is the expected value of a demo at 20% close and ₹40,000 per customer. It is not LTV unless ₹40,000 already is. Full CAC still adds people and tools. Do not bid ₹8,000 if margin is thin.
Result
What this changes for you
Bids get a number: if a lead is worth ₹4,000, a ₹5,000 CPA is a hole. The argument leaves “leads are cheap.”
Common mistakes
- Using list price as customer value when discounting is the norm.
- A 50% close rate from five leads.
- Comparing lead value to CAC. Lead value is per lead. CAC is per customer.
- Updating value in the ads account and never in this sheet.
FAQ
Lead Value Calculator FAQ
How does a lead value calculator work?
Lead value = close rate × average customer value. 20% × ₹40,000 = ₹8,000 per lead. Compare that to CPA before you buy more leads.
Should a lead value calculator use LTV or first order?
Use LTV if you trust it. If you only have first-order value, say so. Do not call a first invoice “lifetime.”
What if I do not know close rate for a lead value calculator?
Get a cohort from CRM first. Guessing 30% because a blog said so will set a CPA cap you cannot keep.
Is lead value from a lead value calculator the same as CAC?
No. Lead value is what a lead is worth. CAC is what you paid to get a customer. Keep the words separate.
