SaaS CAC Blended vs Paid 2027 Calculator
Calculate both blended Customer Acquisition Cost (CAC) and paid-only CAC for SaaS in 2027 — separate organic from paid spend to see true marketing efficiency.
Blended vs Paid CAC
Blended CAC = total sales+marketing ÷ all new customers (organic + paid). Paid CAC = paid spend ÷ paid-attributed customers. Blended can hide paid CAC inefficiency when organic dominates.
Why Both Matter
Blended for unit economics — tells investors true cost. Paid for marketing optimization — tells which channels work. Cohort blended CAC at 6-12 month intervals to see scaling efficiency.
Best-in-Class Targets
CAC payback < 12 months mid-market, < 18 enterprise. LTV:CAC > 3:1. Blended CAC < 1/3 of first-year ACV. Paid CAC < 50% of LTV.
