Measures return on investment by comparing net gain or loss against the original cost, expressed as both a percentage and a dollar amount. Essential for marketing campaign evaluation, equipment purchase decisions, real estate investment analysis, and comparing investment opportunities.
CAC = fully-loaded sales + marketing cost ÷ new customers in the same period. Example: $50,000 spend for 500 customers = $100 CAC. Same-period matching matters — don't divide Q1 spend by Q2 customers.
Ad spend plus salaries, tools, agency fees, and content production. Ad-only CAC of $40 becomes $100+ fully loaded — the version investors and the LTV:CAC ratio actually use.
Payback = CAC ÷ monthly gross profit per customer. Example: $100 CAC ÷ ($50 × 80%) = 2.5 months. Under 12 months is healthy for SMB SaaS; enterprise tolerates 18+ on annual contracts.
Both. Blended ($100) sets budgets; channel splits reveal waste — e.g., paid search at $60 vs events at $400. Kill or fix the $400 channel instead of averaging it away.
Usual causes: experimental spend on a new channel, sales hiring ahead of ramp (cost now, customers later), or a denominator dip from seasonality. Compare 3-month rolling CAC before reacting.
