Source-backed CAC data is useful only when its customer segment, calculation method, and period match yours. Read it with deal size, gross margin, customer lifetime value, and payback period.
Published CAC figures often use different customer populations and cost definitions. Compare a result only with a dataset that documents a matching segment, period, and calculation method.
Segment by sales motion and customer type. A self-serve customer, an enterprise account, and a repeat purchaser can involve different costs and revenue profiles. Separate paid and organic acquisition when assessing channel decisions.
Before using an external comparison, confirm whether it includes salaries, commissions, agencies, tools, content, events, and organic customers. A dollar range without those definitions is not a reliable benchmark.
The figures below are averages from First Page Sage's B2B SaaS client data, collected from 2019 through 2024 and averaged across marketing channels. They are a vendor-client sample, not a whole-industry estimate; the report does not disclose a client count or geography.

Blended CAC divides total sales and marketing spend by all new customers, including organic and word-of-mouth customers. Paid CAC isolates paid-channel spend and customers attributed to those channels.
Use the same definition over time. Track blended CAC for overall unit economics and paid CAC when evaluating channel investment.
Fully loaded CAC can include salaries, commissions, SDR headcount, marketing tools, events, content production, and agency fees. State which costs are included before sharing or comparing the result.
A partial measure can still be useful for a specific channel, but should not be compared directly with a fully loaded measure.
CAC payback estimates how long gross profit from a customer takes to recover acquisition cost: CAC Payback = CAC / (Monthly ARPU × Gross Margin). Bessemer Venture Partners presents segment-specific targets of under 12 months for SMB SaaS, under 18 months for mid-market, and under 24 months for enterprise. These are operating guidelines, not universal rules.
Channel performance can change with spend, competition, audience composition, and conversion. In a simplified model where spend and traffic stay constant, doubling conversion rate halves CAC. Real acquisition systems may change more than one input at once.
Review CAC alongside cohort retention, gross margin, payback, and the customer segment. A higher CAC can be sustainable when the underlying customer economics support it.
Use the free calculator to compute blended and channel-specific acquisition cost, then review it with LTV and payback assumptions.
For a fully loaded CAC calculation, include the sales and marketing costs required to acquire customers, including relevant salaries and commissions. Document any costs you exclude.
Bessemer Venture Partners gives a segment-specific guideline of under 12 months for SMB SaaS, under 18 for mid-market, and under 24 for enterprise. Use it only with comparable gross-margin, retention, and sales-cycle assumptions.
