Customer Acquisition Cost (CAC)

CAC Is Getting More Expensive — And Most Teams Are Measuring It Wrong

CAC has increased approximately 60% over five years (ProfitWell/Paddle, 2025), and the trend is not slowing down. More competition, more channels, and more sophisticated buyers mean it costs more to win every deal. The median new CAC ratio is $2.00 of S&M per $1.00 new ARR, up 14% year-over-year. Top quartile companies achieve $1.00. Bottom quartile sits at $2.82 (Benchmarkit, 2025).

The bigger problem is not the rising cost — it is how teams calculate it. Most companies exclude overhead, tooling costs, and management salaries from the denominator. That produces a flattering number that does not reflect reality.

CAC Benchmarks by Segment

What you sell and who you sell to determines what "good" looks like. A $10K CAC is excellent for enterprise and terrible for SMB.

Segment	Median CAC	Why It Varies
SMB (<$15K ACV)	$200-$700	Low-touch, self-serve or inside sales
Mid-Market ($15K-$100K)	$1,000-$5,000	Multi-stakeholder, solution selling
Enterprise (>$100K ACV)	$10,000-$15,000	Complex procurement, long cycles

The mistake is comparing your CAC to the wrong benchmark. If you are selling a $50K ACV product with an enterprise sales motion and comparing yourself to PLG companies, you will always look inefficient. Context is everything.

Blended CAC vs. New-Logo CAC: Track Both

The gap between blended and new-logo CAC reveals your expansion efficiency. Blended CAC includes expansion revenue in the denominator, which improved 13% to $1.40 per ARR dollar. New-logo CAC isolates net-new customer acquisition at $2.00 per ARR dollar (Benchmarkit, 2025). That 43% gap proves what every RevOps leader already knows: expansion revenue is dramatically cheaper than new-logo acquisition.

If your blended CAC looks healthy but your new-logo CAC is rising, you are masking an acquisition problem with retention success. Both are important — but they require different playbooks.

How to Actually Reduce CAC

Cutting spend is the lazy answer. Improving efficiency is the right one. Three moves that reduce CAC without slowing growth: shorten the sales cycle by tightening qualification criteria (deals that close faster cost less). Increase win rates by improving champion activity and executive engagement earlier in the deal. Shift channel mix toward higher-efficiency sources like organic, referral, and community.

The ultimate lever is CAC payback period — the faster you recoup acquisition cost, the faster your growth engine self-funds. Track CAC in isolation and you are looking at a cost. Track it alongside payback and LTV:CAC ratio, and you are looking at a system.
