Answers
CAC = (marketing spend + sales spend) ÷ new customers acquired. Include paid media, agency fees, sales-related payroll, tooling, and any acquisition cost tied to that period.
0% ROI is break-even. Above 100% means revenue doubles spend. SaaS teams often target 200%+ once mature; newer campaigns near 0–50% briefly can still pay off with longer lifetime value.
ROAS divides revenue by spend — 2× means $2 of revenue per $1. ROI divides (revenue − spend) by spend and shows it as %. ROAS emphasizes top-line yield; ROI emphasizes surplus vs budget.
Profit = revenue × gross margin − total spend so you can subtract COGS, fees, hosting, support, or other marginal costs.
