Why Customer Lifetime Value Matters

Customer Lifetime Value (CLV) is the total revenue you can expect from a single customer over the duration of your relationship. Knowing this number is fundamental to building a profitable business because it tells you how much you can afford to spend acquiring each customer.

If your CLV is $500 and your customer acquisition cost is $100, you have a healthy 5:1 ratio. If CLV drops to $120, that same acquisition spend becomes unsustainable. This calculator helps you measure, monitor, and improve CLV.

Enter your average order value, purchase frequency, and customer lifespan, and the tool calculates CLV along with actionable benchmarks for your industry.

Key Features

Simple CLV Formula

Calculate CLV using Average Order Value x Purchase Frequency x Customer Lifespan for a quick estimate.

Advanced Model

Factor in gross margin, discount rate, retention rate, and churn for a more accurate net-present-value CLV.

Segment Comparison

Calculate CLV for different customer segments to identify your most valuable audiences.

CLV:CAC Ratio

Enter your customer acquisition cost to see the CLV to CAC ratio and whether your unit economics are healthy.

Sensitivity Analysis

Frequently Asked Questions

What is a good CLV to CAC ratio?

A 3:1 ratio is generally considered healthy. Below 1:1 means you are losing money on each customer. Above 5:1 may mean you are under-investing in growth.

How do I improve CLV?

Three levers: increase average order value (upselling, bundling), increase purchase frequency (loyalty programs, email marketing), or extend customer lifespan (improve retention, reduce churn).

Should I use simple or advanced CLV?

Use simple CLV for quick estimates and the advanced model (with discount rate and margins) for financial planning and investor presentations.

How do I estimate customer lifespan?

Divide 1 by your churn rate. If 5% of customers leave each month, average lifespan is 1/0.05 = 20 months.
