The first time somebody sees a B2B cost per lead figure next to a consumer one, the reaction is always the same. Hundreds of pounds for an enquiry looks indefensible until you look at what a closed deal is worth.
Most of the gap is explained by three things: a smaller audience, a longer cycle, and a bigger prize. The rest is explained by benchmark data that is considerably weaker than it looks.
This is for you if you sell to businesses and are trying to work out whether your numbers are alarming or normal.
What the reliable data says about B2B cost per lead
The most trustworthy figure available is not a B2B-specific one.
WordStream’s 2026 study of 13,474 US search campaigns, covering April 2025 to March 2026, put business services at $93.69 against an all-industry average of $66.69. That study discloses both its sample size and its date range, which most do not.
Figures quoted for narrower B2B sectors run far higher, often into the hundreds. Those come from weaker sources, and it is worth knowing how weak before you plan around them.
Why B2B cost per lead is genuinely higher
Three forces compound, and each one alone would raise the price.
The audience is small. If four thousand companies in the world could buy your product, reaching the right person inside them costs more per head than reaching anybody who might want a takeaway.
The cycle is long. With a six-month path from enquiry to signature, most of the leads you generated this quarter have not resolved yet, so any conversion rate you calculate today understates reality.
The deal is large. A single contract worth tens of thousands justifies a bid that would bankrupt a consumer advertiser, so everybody bids that way and the auction settles high.
None of those is a problem to fix. They are the shape of the market, and a B2B cost per lead of $300 can be perfectly healthy where a consumer one of $30 would not be.
Be careful with published B2B benchmarks
This is where I would spend your scepticism.
First Page Sage publishes B2B cost per lead figures by industry: Financial Services $653, Legal $649, Ecommerce $91. No sample size is given anywhere. Its own note says the report was “prepared by our marketing research team, based on data collected between January 2022 through June 2025”, so a three and a half year blend carries a 2026 label.
HubSpot publishes the same figures, to the dollar, and says openly that its data “combines insights from FirstPageSage’s 2026 report”.
Nothing dishonest is happening. HubSpot credits its source. The problem is downstream: someone quotes HubSpot, someone else quotes First Page Sage, and a room believes two independent sources agree. They are one unaudited dataset appearing twice.
Use those numbers for order of magnitude, say where they came from, and never set a target with them.
Setting a B2B cost per lead target that survives a long cycle
Work backwards from the deal, then pick a milestone you can actually measure this quarter.
Take profit per closed deal and multiply by your win rate from enquiry. If one in twenty enquiries becomes a $40,000 contract at 30% margin, each enquiry is worth $600. That is your ceiling.
Then choose a working target that arrives sooner. Qualified opportunity is the usual choice, because it happens in weeks rather than months and correlates far better with revenue than a form fill does.
Measuring closed business alone in B2B means judging campaigns two quarters after you needed the answer. Measuring form fills alone means judging nothing useful at all.
The signal problem is worse in B2B
Every category suffers when campaigns optimise towards form submissions. B2B suffers most.
The distance between somebody downloading a guide and somebody signing a contract is enormous, and the platform cannot see any of it. Left alone, it will find you an impressive volume of people who download things.
So sending qualified-opportunity or closed-won data back to the ad platform matters more here than anywhere else. Offline conversion tracking is the mechanism, and in B2B it is closer to essential than optional.
If your CRM does not send that data back, you are asking the algorithm to optimise blind and then blaming it for the result.
What about LinkedIn
The usual question, and the usual answer is that the comparison is being made wrong.
LinkedIn enquiries typically cost more than search or Meta enquiries. They can also qualify better, because you are reaching people by job title rather than by search behaviour.
Whether that trade works is a calculation, not an opinion. Cost per qualified opportunity on each channel, using your own qualification data. I have seen the gap close entirely once qualification was included, and I have seen it stay wide. Both happen, and the headline price never predicts which.
The B2B cost per lead trap nobody warns you about
Volume targets. They do more damage in B2B than anywhere else.
Somebody sets a goal of 200 leads a quarter. The team hits it. Sales works through them and finds that most were students, competitors, or people who wanted the guide. Everyone did what was asked and the quarter was wasted.
It happens because volume is easy to measure and quality is not. A form fill is countable on a Tuesday. A qualified opportunity requires somebody to have a conversation first.
The fix is to make the target a qualified one from the start. Fifty qualified opportunities beats 200 enquiries, and it is a harder number to game.
Watch for the softening too. When a volume target is at risk, the definition of a lead quietly loosens. Gated content counts. Webinar signups count. Nothing was falsified, and the number stopped meaning anything.
What to change this week
Four steps.
Work out profit per deal and win rate from enquiry, so you have a real ceiling rather than a borrowed benchmark.
Pick a milestone you can measure within a quarter, most likely qualified opportunity, and make that your working target.
Check whether qualification data flows back to your ad platforms, since in B2B this is the difference between a campaign that finds buyers and one that finds downloaders.
Then, when someone quotes a B2B benchmark at you, ask where it came from and what its sample size was.
The wider piece on judging lead cost covers the ceiling, working out what a lead is worth is the calculation itself, the 2026 figures by industry put business services in context, and lead quality covers the measurement that matters more than cost here.
