💡 Formula Guide
This CPL calculator works out cost per lead, the ad spend it takes to get one enquiry, sign-up or quote request. Use it on a campaign that has already run, or forecast one from an expected click cost and landing page conversion rate. Add your close rate and what a customer is worth, and it shows the most you can pay for a lead before the campaign loses money.
How to Calculate CPL
Cost per lead is total ad spend divided by the number of leads.
A campaign that spent $2,000 and produced 80 leads has a CPL of $2,000 ÷ 80 = $25.
Before a campaign runs, the same figure can be estimated from two numbers:
At a $2.00 CPC and a landing page that turns 5% of visitors into leads, CPL is $2.00 ÷ 0.05 = $40. The formula also shows the two ways to lower CPL: pay less for each click, or convert more of the visitors you already pay for. The CPC Calculator and the Conversion Rate Calculator cover those two inputs.
The Most You Can Pay for a Lead
A lead is not a sale, so its value depends on how many leads become customers. Multiply what a customer is worth, after the cost of serving them, by your lead-to-sale rate.
| Customer value | Cost to serve | Lead-to-sale rate | Break-even CPL |
|---|---|---|---|
| $1,000 | $200 | 10% | $80 |
| $500 | $100 | 20% | $80 |
| $5,000 | $1,000 | 3% | $120 |
Pay less than this for a lead and the campaign makes money. Pay more and it loses money, however low the CPL looks beside a benchmark. Enter the three figures in the calculator's funnel settings and it shows the break-even CPL next to your actual one, with revenue and profit. If customers stay for years, use their lifetime value and not just the first invoice.
What Is a Good Cost Per Lead?
A good CPL is one below your break-even CPL. A $150 lead can be cheap for a law firm and far too expensive for a gym. Benchmarks help you see whether a campaign is far out of line, and nothing more.
The figures below are from LocaliQ's 2026 search advertising benchmarks, which cover Google Ads and Microsoft Ads campaigns. Across all industries the average cost per lead was $66.69, down from $70.11 the year before.
| Industry | Average cost per lead (search ads) |
|---|---|
| Attorneys & Legal Services | $131.63 |
| Furniture | $106.70 |
| Real Estate | $102.51 |
| Business Services | $93.69 |
| Home & Home Improvement | $90.92 |
| Education & Instruction | $77.48 |
| Finance & Insurance | $74.44 |
| Dentists & Dental Services | $72.97 |
| Health & Fitness | $67.36 |
| Physicians & Surgeons | $40.04 |
| Beauty & Personal Care | $39.25 |
| Restaurants & Food | $30.57 |
| Arts & Entertainment | $26.84 |
These are search-advertising averages for mostly local and service businesses. Business Services is the closest category to B2B lead generation, and B2B leads bought through LinkedIn or trade media usually cost more than search leads. Social lead forms, where a visitor submits details without leaving the app, usually produce cheaper leads that need more qualifying.
CPL, CPA and CAC
| Metric | Formula | What it measures |
|---|---|---|
| CPL | Ad spend ÷ leads | The cost of one enquiry |
| CPA | Ad spend ÷ conversions | The cost of one sale or other counted result |
| CAC | All sales and marketing costs ÷ new customers | The full cost of one new customer |
CPL sits at the top of that chain. Divide it by your lead-to-sale rate and you have the ad cost per customer, which is what the CPA Calculator measures directly. Add salaries and tools and you have the figure in the CAC Calculator.

Frequently Asked Questions
How do I calculate cost per lead?
Divide what you spent on a campaign by the number of leads it produced. $2,000 of ad spend that brought in 80 leads is a CPL of $2,000 ÷ 80 = $25. To forecast it before spending, divide your cost per click by your landing page conversion rate: a $2.00 CPC at a 5% conversion rate is $40 per lead.
What counts as a lead?
Anyone who gives you a way to contact them and a reason to: a form fill, a quote request, a booked call, a trial sign-up or a phone enquiry. Decide the definition before you calculate, because CPL changes a great deal depending on whether you count every form fill or only leads that sales has accepted as qualified.
What is the difference between CPL and CPA?
CPL is the cost of a lead, a person who has shown interest. CPA is the cost of an acquisition, which usually means a paying customer. The two are linked by your close rate: at a $25 CPL and a 10% lead-to-sale rate, the cost per customer is $25 ÷ 0.10 = $250.
How is B2B cost per lead different?
B2B leads usually cost more and are worth more. The buying group is small, the sales cycle is long and one contract can be worth thousands, so a CPL of several hundred dollars can still be profitable. That makes the break-even figure more useful than any average: enter your close rate and contract value in the funnel settings to see your own limit.
Should I count the cost of content and tools in CPL?
For comparing ad campaigns, ad spend alone is the usual basis, and it is what ad platforms report. For judging a whole channel, add what it took to run it: agency fees, landing page software and the cost of the content the lead signed up for. Say which version you are using, because the two are not comparable.
Why do cheap leads sometimes cost more in the end?
Because a low CPL often comes with a low close rate. Leads from an in-app form that fills itself in are cheap, but many of the people never meant to enquire. If 2% of $10 leads become customers, each customer costs $500. If 20% of $60 leads do, each customer costs $300.
