Why a Single CAC Payback Number Hides More Than It Shows
Sixteen months is the kind of number that gets repeated as if it applies evenly across a company. It does not. The 2026 Aleph and Benchmarkit SaaS and AI Performance Benchmarks, drawing on full-year 2025 actuals from 342 B2B SaaS and AI-native software companies, found sub-$5,000 ACV deals paying back in a median 11 months, high-volume, low-touch digital acquisition that recovers cost quickly, against a 22-month median for $50,000 to $100,000 ACV enterprise deals. That is close to a two-times spread hiding inside the same blended figure.
The report’s own recommendation is explicit: pull payback period by growth cohort, ACV band, and go-to-market motion, then benchmark against the matching segment, not the 16-month median. A company comparing itself to the wrong slice of that range will read either an artificially alarming or an artificially reassuring number.
What Capital Efficiency Looks Like Once You Adjust for Company Type
Revenue per employee, a related capital-efficiency measure, runs a median $141,125 in ARR as of 2026, up from $129,724 in 2025, per SaaS Capital’s 15th annual survey. That measure splits meaningfully by funding type too: bootstrapped companies between $5 million and $10 million in ARR show $177,240 in ARR per employee, against $152,295 for equity-backed companies at the same revenue stage, evidence that capital efficiency and funding source move together, not independently.
The Numbers
The overall median CAC payback period across B2B SaaS and AI-native software companies is 16 months, based on full-year 2025 actuals from 342 companies, 198 of which reported CAC payback specifically.
By ACV tier, sub-$5,000 ACV deals show an 11-month median CAC payback, reflecting high-volume, low-touch digital acquisition that recovers cost quickly.
Enterprise-tier deals, $50,000 to $100,000 ACV, show a 22-month median CAC payback (25th percentile 15 months), roughly double the sub-$5,000 tier’s recovery time.
The report’s own guidance is to benchmark CAC payback by growth cohort, ACV band, and go-to-market motion against the matching segment, not against the blended 16-month median.
