Why LinkedIn CPCs run 5 to 10x other platforms

LinkedIn does not have to be cheap. The audience is professional buyers, the auction is thin (far fewer advertisers than Meta or Google), and the data signal is the strongest in B2B: job title, company, seniority, function, even years of experience. All three push prices up. A $7 click that reaches a Director of Engineering at a 1,000-person SaaS is worth more than a $2 Google click that lands a curious intern, so the price is rational once you account for who you are reaching.

The math, top to bottom

A LinkedIn budget is a chain of multiplication. You start from the pipeline you need and work backward to clicks:

sales_required   = pipeline_goal / acv
leads_required   = sales_required / win_rate
clicks_required  = leads_required / conversion_rate
budget           = clicks_required * cpc

The conversion rate is where most teams get this wrong. It forks sharply by ad format, which we will get to.

Where the LinkedIn math gets weird

LinkedIn click-to-lead conversion rates fork by ad format more than any other platform. Lead Gen Forms (the prefilled form that pops up inside the LinkedIn feed) convert 12 to 18 percent of clicks. Sending traffic to your own landing page typically converts 5 to 10 percent. Same audience, same ad creative, same CPC, but the format you pick can swing your required budget by 2 to 3x. Pick the right one before you run the math.

When LinkedIn is the wrong channel

If your AOV is under $200 or your sales cycle is shorter than a week, LinkedIn is the wrong place. The $5 to $12 CPC only pencils when LTV is meaningful (typically $5,000 ACV+) and when you can wait 30 to 90 days for pipeline to close into revenue. Below that threshold, Meta and Google produce the same outcome at a fifth of the spend.

What ROAS to expect

B2B with high LTV runs profitably at lower ROAS than ecommerce because contracts compound. Quick benchmarks for first-year ROAS:

• SMB SaaS, $5K to $15K ACV, fast cycle: 2x to 4x is normal
• Mid-market, $25K to $75K ACV, 60-90 day cycle: 1.5x to 3x
• Enterprise ABM, $100K+ ACV, 6+ month cycle: 0.5x to 1.5x in year one, 5x+ over the contract life
• Anything below 0.5x first-year ROAS at any tier means the LinkedIn audience is too broad or the sales motion is leaking

A worked example

Say you sell B2B software at $25,000 first-year ACV and your sales team closes 12 percent of LinkedIn-sourced leads. You want $500,000 in pipeline next quarter. At a $9 CPC and a 14 percent Lead Gen Form conversion rate, the math says you need 20 sales, 167 leads, 1,190 clicks, and roughly $10,700 in LinkedIn spend, for a 47x pipeline-to-spend ratio. Drop the conversion rate to 6 percent (you sent traffic to a landing page instead of using Lead Gen Forms) and the budget jumps to $25,000 with a 20x ratio. Both are workable. Now drop ACV to $3,000 (SMB segment instead of mid-market) and the same setup ratios drop to 5x and 2.4x respectively, the second of which is at the edge of profitable depending on win rate.

That kind of sensitivity is why the worst-moderate-best framing matters more than any single number.
