Lead Value Calculator: What Is a B2B Lead Worth, and How Much Should You Pay?

Most advice on cost per lead starts with an industry average. That's the wrong place to start. The "average B2B cost per lead of $198" quoted in 2026 articles matches a HubSpot survey from 2017, and other current benchmarks for the same industry differ by more than 2x. What a lead is worth to you depends on three of your own numbers: what a customer is worth, how many leads become customers and what it costs to close them.

This guide gives you the formula, an interactive lead value calculator, worked examples and the benchmarks worth using as starting inputs.

How to calculate what a lead is worth

A lead's value is the value of a customer multiplied by the chance that the lead becomes one:

Lead value = customer lifetime value × lead-to-customer rate

Customer lifetime value (LTV) should be based on gross margin, not revenue. A common version, used by GrowthSpree, is:

LTV = annual revenue per customer × gross margin × average customer lifetime in years

Lead value formula: annual revenue $15,000 times 80% gross margin times 3 years equals $36,000 customer lifetime value; $36,000 times a 3% lead-to-customer rate equals $1,080 per lead — How to calculate what a lead is worth. Source: SPONA

For example, a customer paying $15,000 a year at an 80% gross margin who stays for three years is worth $36,000. If 3% of your leads become customers, each lead is worth $1,080 on average.

Lead value calculator

Use the calculator below with your own numbers. It shows what a lead is worth, the most you can afford to pay per lead and how many leads you need per customer.

Step	Input or result	Example
1	Annual revenue per customer	$15,000
2	Gross margin	80%
3	Average customer lifetime	3 years
4	Customer lifetime value (1 × 2 × 3)	$36,000
5	Lead-to-customer rate	3% (about 33 leads per customer)
6	Value per lead (4 × 5)	$1,080
7	Acceptable CAC at a 3:1 target (4 ÷ 3)	$12,000
8	Sales cost per customer	$5,000
9	Maximum cost per lead ((7 − 8) × 5)	$210

The calculator subtracts your sales cost per customer before working out the maximum cost per lead. That matters: customer acquisition cost (CAC) includes sales salaries, commissions and tools, not just lead costs. SaaSHero cites research finding that counting only ad spend can make CAC look 1.5 to 4 times smaller than the fully loaded figure.

How much should you pay per lead?

Work backwards from a target ratio of customer value to acquisition cost. The most common target is 3:1, meaning each customer brings in three times what it cost to win them. Optifai's study of 939 B2B SaaS companies found a median LTV:CAC of 3.2:1, and treats 3:1 to 5:1 as healthy.

Maximum cost per lead = (LTV ÷ target LTV:CAC − sales cost per customer) × lead-to-customer rate

Using the example above with a 3:1 target and $5,000 of sales cost per customer: $36,000 ÷ 3 = $12,000 of acceptable CAC, minus $5,000 of sales cost, leaves $7,000 to spend on leads per customer. At a 3% conversion rate, that's a maximum of $210 per lead.

Two cautions. First, a strong ratio can still hide a cash problem: Optifai recommends CAC payback under 12 months for SMB customers and under 18 months for mid-market. Second, very high ratios can mean you're underspending on growth, as Optifai and SaaSHero both note.

What a lead is worth at different deal sizes

Small changes in deal size or conversion rate change lead value dramatically. This table assumes an 80% gross margin and a three-year customer lifetime, with the maximum cost per lead at a 3:1 target in brackets (before sales costs).

Annual revenue per customer	1% lead-to-customer	3% lead-to-customer	5% lead-to-customer
$5,000	$120 ($40)	$360 ($120)	$600 ($200)
$15,000	$360 ($120)	$1,080 ($360)	$1,800 ($600)
$50,000	$1,200 ($400)	$3,600 ($1,200)	$6,000 ($2,000)

The same $200 lead can be a bargain or a loss. It's cheap if your customers pay $50,000 a year and 3% of leads convert, and unaffordable if they pay $5,000 a year and 1% convert. Upcision makes the same point with its own work-backwards table.

Why industry cost per lead averages mislead

Benchmarks are useful for sanity checks, but most aren't comparable. We traced several widely quoted figures back to their sources:

Some "2026" averages are from 2017. Revnew's 2026 guide lists an average B2B cost per lead of $198, with financial services at $272, healthcare at $286 and manufacturing at $235. Those match, to the dollar after rounding, a 2017 HubSpot survey of 350+ companies ($198.44, $271.54, $285.82 and $235.09). LeadSpot flags the same recycling.
Company-size figures repeat too. Sopro's 2025 benchmarks list $348 per lead for companies with 1,000+ employees and $146 for 2 to 50 employees, identical to the 2017 survey's $348.93 and $146.94.
Current sources disagree widely. First Page Sage, using data from January 2022 to June 2025, puts financial services at $653 blended and B2B SaaS at $237. WordStream's 2026 search ad benchmarks, from 13,000+ U.S. campaigns, show an average of $66.69, mostly for form fills across all business types.
"Lead" means different things. Upcision prices a contact record at about $1, a marketing lead at $75, a qualified lead at $250 and a booked appointment at $500. Belkins reports $420 to $3,080 for the qualified outbound leads it measures.

Financial services cost per lead depending on the source: $272 in a 2017 HubSpot survey still republished as 2026 data, $400 for a qualified lead per Upcision, $461 per Sopro, $653 blended per First Page Sage — One industry, four "averages". Sources: HubSpot 2017 via MarketingCharts, Upcision, Sopro, First Page Sage

Use benchmarks to check whether a quote is in a reasonable range for the type of lead you're buying, then decide with your own math.

Cost per lead vs. cost per opportunity vs. CAC

Cost per lead (CPL) only tells you the price of a contact. Two follow-on numbers tell you whether it's worth it:

Cost per opportunity = CPL ÷ lead-to-opportunity rate. LeadSpot uses this formula to compare channels and shows that a cheap lead with poor conversion can cost far more per opportunity than an expensive one.
Cost per customer = CPL ÷ lead-to-customer rate, plus sales costs. Revnew's example: a $500 lead converting at 30% costs $1,667 per customer, while a $50 lead converting at 2% costs $2,500.

The Starr Conspiracy puts it simply: a $500 lead converting at 15% beats a $100 lead converting at 2%.

Funnel benchmarks to use as starting inputs

If you don't yet know your own conversion rates, published ranges give you a starting point. Understory's benchmark summary for B2B SaaS:

MQL to SQL: 15% to 21%, depending on how strictly you qualify
SQL to opportunity: 36% to 42% at the median
Opportunity to closed-won: 22% to 35%, depending on deal size
Overall lead to customer: 2% to 5%, with top-quartile companies at 5% to 6%+

Starr Conspiracy also cites 2% to 5% for overall lead-to-customer rates. Replace these with your own numbers as soon as you have three to six months of data, because your definition of a lead changes everything.

How to raise what each lead is worth

Lead value has two levers: customer value and conversion rate. Most teams can move conversion faster:

Tighten targeting. Leads that fit your ideal customer profile convert at higher rates, which raises the value of every lead.
Verify contact data. Bad emails and phone numbers turn paid-for leads into zero-value leads.
Respond fast. Understory notes research suggesting leads contacted within 5 minutes are much more likely to qualify than those contacted after 30 minutes.
Measure by source. Calculate lead value per channel, not just overall, so you stop funding sources whose leads rarely convert.

FAQ

How much is a B2B lead worth?

Multiply your customer lifetime value by your lead-to-customer rate. A customer worth $36,000 in gross margin over their lifetime, with 3% of leads converting, makes each lead worth about $1,080.

How do you calculate lead value?

Lead value equals customer lifetime value times lead-to-customer conversion rate. Calculate lifetime value from gross margin, not revenue: annual revenue per customer × gross margin × years retained.

What is a good cost per lead for B2B?

One that keeps your customer acquisition cost within your target ratio, commonly one-third of customer lifetime value. Use the formula: (LTV ÷ 3 − sales cost per customer) × lead-to-customer rate.

What is the average cost per lead in B2B?

It depends on the source and the definition of a lead. First Page Sage puts B2B SaaS at $237 blended, WordStream's 2026 search ad average is $66.69, and Belkins reports $420 to $3,080 for qualified outbound leads. Several widely quoted figures, including a $198 average, come from a 2017 survey.

What is the difference between cost per lead and CAC?

Cost per lead is what you pay to acquire one lead. Customer acquisition cost is the total sales and marketing cost to win one customer, which includes the cost of all the leads that didn't convert plus sales salaries, commissions and tools.
