Customer Acquisition Cost & Lifetime Value

Two numbers decide whether growth pays: what a customer costs to win, and what they are worth before they leave.

Revenue tells you what is coming in. Unit economics tells you what you keep to grow. That difference is the whole game when you are deciding whether to raise ad spend, hire a sales team, or change your pricing — it is what keeps margins expanding as you scale instead of quietly eroding.

The tool reads the relationship between what it costs to get a customer and what that customer returns over time, so growth stops being a guess.

What You'll Need

• Customer Acquisition Cost (CAC): the total sales and marketing investment required to win a single customer.

• Customer Lifetime Value (LTV): the total net profit a customer generates over the entire relationship.

• Churn & Retention: how fast customers leave versus how long they stay, which sets the ceiling on your growth.

Your Results

• CAC: how much of your capital is consumed just to get someone through the door.

• LTV: accounts for gross margins and retention to show a lead's true long-term value.

• LTV:CAC Ratio: the scalability check. 1:1 or lower: you lose money on every customer. 3:1: the Golden Ratio for sustainable, profitable growth.

• Payback Period: how many months it takes to break even on a new customer. The shorter it is, the sooner you can reinvest that cash.

Worth Knowing

Improving your Retention Rate by just 5% can raise LTV — and total profit — by over 25%. Keeping customers moves the number more than winning new ones.
