Common Mistakes to Avoid

❌ Not including churn

LTV assumes average lifespan. Higher churn = lower LTV. Improve LTV by reducing churn.

❌ Confusing revenue LTV with profit LTV

LTV should be based on gross profit, not revenue. A $1,200 LTV with 40% margin = $480 profit LTV.

Frequently Asked Questions

LTV:CAC ratio?

Target 3:1 or higher. LTV $1,200 / CAC $400 = 3:1. Below 3:1 means slow payback or unprofitable growth.

CAC (Customer Acquisition Cost)?

Total marketing and sales spend divided by new customers acquired. CAC = $100,000 spend / 200 customers = $500 CAC.

Payback period?

CAC / monthly gross profit per customer. CAC $500, monthly gross $50 = 10-month payback.
