Customer Lifetime Value Calculator

What one customer is actually worth over the years they stay with you — and the most you can afford to spend to win one. Add your acquisition numbers to see your LTV:CAC ratio and how fast each customer pays back.

Customer economics

Gross margin = what's left of each sale after the direct cost of delivering it (materials, product cost, sub-labor, payment fees). It's the part that actually accrues to you, so LTV is measured on margin — not revenue.

Acquisition (optional — unlocks LTV:CAC)

Include ad spend, lead-gen subscriptions, and the share of payroll spent chasing new customers. Leave blank if you only want lifetime value.

If a customer is worth this much, a missed call isn't a missed call

It's that number walking to a competitor. Once you know what a single customer is worth over their lifetime, the math on answering every call, replying to every lead, and following up on every quote changes completely. BizBot's verticals catch the calls, texts, and leads you're currently letting slip — so the customers you already paid to attract actually become customers.
