It depends on your audience size, target reach, and how long your sales cycle is. Most B2B companies underspend on LinkedIn because they follow LinkedIn's default recommendation of $25/day — which typically only reaches 5–10% of a target audience. The Reach Ratio™ formula calculates the actual budget needed to reach 80% of your ICP, which is the threshold where demand generation starts compounding. For a 10,000-person audience with a 6-month sales cycle, expect to invest around $7,000–$8,000/month to hit that 80% penetration. See how KlientBoost's LinkedIn Ads team can help you get there.
LinkedIn CPMs vary significantly by audience. Broad B2B targeting in the US currently averages around $90–$100. If you're targeting senior decision-makers (VP+ titles) in SaaS or financial services, expect CPMs between $120–$200. The best way to find your actual CPM is to pull it directly from LinkedIn Campaign Manager using a 90-day lookback window. Avoid relying on published benchmarks too much as every industry and target audience is different.
The Reach Ratio™ is a budget-sizing formula developed by KlientBoost that calculates the minimum LinkedIn Ads spend needed to reach a meaningful percentage of your target audience. The formula is: (Audience Size × Target Reach × Frequency Factor ÷ 1,000) × CPM ÷ Months. It accounts for how many people you need to reach, how often they need to see your ads each month, what you're paying per 1,000 impressions, and how long your campaign needs to run based on your sales cycle.
Research consistently shows that only about 5% of B2B buyers are actively in-market at any given time. If your LinkedIn Ads only reach 10–20% of your target audience, you're missing the vast majority of future buyers who aren't searching yet but will be in 3–12 months. Reaching 80%+ of your audience with consistent frequency builds brand familiarity so that when those buyers do enter a buying cycle, your company is already top of mind. Underspending just makes the money you do put into LinkedIn Ads less effective.
Frequency factor is the number of times each person in your audience should see your ads per month. Smaller audiences (10k–50k) need a lower frequency factor (around 10x) because the ad platform can serve impressions more efficiently. Larger audiences (1M+) need higher frequency factors (14–17x) because LinkedIn's delivery algorithm spreads impressions more thinly across bigger pools.
