Facebook ads for SaaS cost about $1.95 a click and $145 per lead weighted by spend, with the median B2B advertiser paying $179 per lead in 2025. That is roughly half of LinkedIn. A fair test needs 20 to 30 leads, about $3,000 to $5,500, and it pays back fastest for products a broad audience can try without a demo. Retargeting and static images are the cheapest place to start.
How much do Facebook ads cost for SaaS?
The best public figures come from Metadata, which measured 153 B2B advertisers and $57.6 million of spend on Facebook and Instagram during 2025. On Facebook a click cost $1.95, a thousand impressions $15.50, and 0.79% of people who saw an ad clicked it. Of those who clicked, 2.6% became a lead.
Weighted by spend, a Facebook lead cost $145. The advertiser in the middle of the pack paid $179, which is the better planning number for a SaaS company spending its first few thousand dollars, because big accounts with years of pixel data pull the weighted figure down.

What is the minimum budget for Facebook ads?
Meta's help center asks for at least $1 a day on ad sets charged for impressions, and ad sets that optimize for clicks or conversions are reported to need about $5 a day. Those floors let an ad run. They do not let Meta's delivery learn who converts, which needs a steady stream of lead events every week.
Plan for 20 to 30 leads before you judge anything. At the $145 spend weighted cost that is $2,900 to $4,350, and at the $179 median $3,600 to $5,400. Spread it across four to six weeks with one campaign and one audience, so the result belongs to the offer and not to a dozen half funded ad sets.
Do Facebook ads work for B2B SaaS?
They work best for products that a wide professional audience understands in one sentence and can start using the same day: scheduling, invoicing, design, email, simple analytics. They struggle with products sold to one job title inside large companies, because Facebook cannot target by title or company size the way LinkedIn can.
Three findings from the 2025 data shape a sensible first campaign:
Retargeting first. Site visitors cost $120 per lead against $166 for cold prospecting audiences.
Images before video. Static images averaged $136 per lead, video $225.
Let Instagram in. Instagram leads cost $138 weighted by spend, and 4.0% of its clicks became leads against 2.6% on Facebook.
Creative does most of the work on Meta, because the audience is not searching for you. Test three to five different problems your product solves rather than five versions of one headline. If the team runs dry, brainstorm a few dozen ad angles from one product brief and keep the ones a customer would recognize.

Facebook leads look cheap next to search, but a search lead typed the problem and a Facebook lead was interrupted while scrolling. Many SaaS teams find fewer Meta leads turn into paying customers, so compare channels on cost per paying customer after 60 days. The search side of the comparison is worked through in Google Ads for SaaS, and the title targeted option in LinkedIn ads for SaaS.
Are Facebook ads worth it for SaaS?
Assume one lead in ten becomes a customer. At the $179 median that is about $1,790 of ad spend per customer. If your Meta leads close at 5%, double it.
| Product price | Months to earn back $1,790 | Verdict |
|---|---|---|
| $50 a month self serve | 36 | Does not pay back |
| $250 a month team plan | 7.2 | Worth a test |
| $1,000 a month mid market | 1.8 | Worth a test |
Assumes a 10% lead to customer rate and the median Facebook cost per lead.
For a $50 a month product, three years to earn back one customer is not a channel. Those products do better where people already shop for software: a listing on our category pages and on competitors' alternatives pages costs less in a year than two Facebook leads. Once that is converting and you know your close rate, a Meta test becomes a measured bet. The full channel list with entry prices is in where to advertise your SaaS.
