Frequently asked questions
3:1 or higher is considered healthy — you earn 3× what you spend to acquire each customer. Below 1:1 means you lose money on every customer. 5:1+ may indicate you are under-investing in growth. Most VCs look for 3-5x.
LTV = ARPU / monthly churn rate. If ARPU is $50/month and monthly churn is 3%, LTV = $50 / 0.03 = $1,667. This represents the total revenue a customer generates before churning. Some models discount by gross margin.
Enterprise SaaS: <1% monthly. SMB SaaS: 3-5% monthly. Consumer subscriptions: 5-8% monthly. Every 1% reduction in monthly churn dramatically increases LTV. A 5% vs 3% churn rate means 20-month vs 33-month average customer lifetime.
Almost always reduce churn first. A 1% churn reduction increases LTV by 20-50% depending on your current rate. The same dollar spent on retention typically returns 5-7× more than the same dollar spent on acquisition.
