Frequently asked questions
How do I calculate customer lifetime value (CLV)?
Transactional: CLV = Average order value × Purchases per year × Customer lifespan (years) × Gross margin %. Subscription: CLV = (Monthly ARPU ÷ Monthly churn rate) × Gross margin %. Example: $85 AOV × 6 purchases/year × 3 years × 70% margin = $1,071 net CLV. This customer lifetime value (CLV) calculator applies both formulas instantly.
What inputs do I need to estimate lifetime value accurately?
For transactional businesses: average order value, purchase frequency, customer lifespan, and gross margin. For subscription/SaaS: monthly ARPU, monthly churn rate, and gross margin. For CLV:CAC analysis, add your customer acquisition cost. Accurate CLV requires real data from your CRM, Shopify, or billing system, not guesses.
How does churn rate affect customer lifetime value?
Higher churn shortens average customer lifespan and lowers CLV. Formula: Avg lifespan (months) = 1 ÷ Monthly churn rate. At 5% monthly churn, average lifespan is 20 months. At 10% churn, only 10 months, cutting CLV roughly in half. Use Subscription mode to model churn impact on CLV.
What's a good CLV to CAC ratio?
A CLV:CAC ratio of 3:1 or higher is the standard benchmark for healthy SaaS and subscription businesses. Below 1:1 means you lose money on each customer. 2:1 is acceptable but tight. 3:1–5:1 is healthy. Above 5:1 may mean you are under-investing in growth. Use CLV vs CAC mode to check your ratio and payback period.
Can I forecast future revenue using CLV?
Yes. Multiply CLV by your expected new customers per year to forecast lifetime revenue from acquisitions. Multiply CLV by total customer count to estimate the lifetime value of your entire customer base. Use Revenue forecast mode: enter CLV, total customers, and annual new customers for both projections.
