Everything you need to know about SaaS unit economics.
For most SaaS businesses, an LTV:CAC ratio of 3:1 is considered the industry benchmark for health. A ratio of 5:1 or higher is excellent and often seen in highly efficient VC-backed startups. If your ratio is below 3, it means you're spending too much to acquire customers relative to their value.
In this simplified calculator, we use the formula: LTV = Average MRR per Customer / Monthly Churn Rate. For example, if your ARPU is $100 and your churn is 5%, your LTV is $2,000. In more complex models, you would also account for gross margin.
It's the number of months it takes for a customer to pay back the cost of acquiring them. A payback period under 6 months is exceptional, while 12 months is the standard limit for capital efficiency. If it takes 24+ months, you'll need significant capital to survive growth.
Churn is the silent killer of SaaS. Even a small increase in churn significantly reduces your LTV, which in turn lowers your LTV:CAC ratio. Reducing churn is often more cost-effective than increasing acquisition budget, as it compounds your customer base over time.
