Pro Tips
LTV:CAC Ratio: A ratio of 3:1 or higher is healthy for SaaS. Below 2:1 means you're losing money on each customer.
Payback Period: Under 12 months is ideal. Above 18 months means you're tying up cash too long.
Gross Margin Matters: Use gross margin, not revenue. High revenue with low margins has poor LTV.
CAC by Cohort: Your first customers usually cost more to acquire than later ones. Track CAC by acquisition channel.
