Compare CAC and ROAS without mixing up what each metric tells you
This model helps SaaS teams evaluate acquisition performance from two angles: how much it costs to acquire customers and how much revenue advertising spend returns. Use it to compare channels, understand payback, and explain why CAC and ROAS can point to different decisions.
CAC calculator
Calculate customer acquisition cost by channel using spend, new customers, sales-assisted costs, and campaign assumptions.
ROAS calculator
Measure revenue returned from paid media or campaign spend without treating ROAS as a complete profitability metric.
Channel comparison
Review paid search, LinkedIn, content, partners, events, and other programs side by side.
Decision view
Identify channels that look efficient on ROAS, expensive on CAC, or worth further testing because of payback and customer quality.
Template sections
The model separates acquisition cost from ad return, then brings both metrics together so teams can make better budget decisions.
Who This Template Is For
SaaS demand gen leaders, growth marketers, finance partners, and founders who need to compare marketing efficiency across channels without relying on a single metric.
How To Use It
Enter your spend, funnel, customer, and revenue assumptions by channel. Review CAC and ROAS separately, then use the combined view to decide where to increase, reduce, or reallocate budget.
