Customer Lifetime Value (CLV) Calculator

Calculate CLV from average order value, purchase frequency, retention, and gross margin per customer.

CLV — Revenue Per Customer Over Their Relationship

BrainyCalculators editorial insight — unique to this tool

CLV = (ARPU × gross margin%) ÷ churn rate for subscription businesses — $50/mo ARPU, 70% margin, 3% monthly churn ≈ $1,167 LTV. CAC:LTV ratio of 1:3 is a common SaaS target. Indian D2C brands with repeat purchase rates model LTV from order frequency × AOV × margin, not MRR.

When to use this calculator

Use to cap customer acquisition spend and prioritize retention. For monthly recurring revenue totals, use SaaS MRR.

Cost to acquire one new customer?

This page values a customer over time. For acquisition spend per customer, use the CAC Calculator →

Average Purchase Value ($)

Purchase Frequency (per year)

Customer Lifespan (years)

CAC ($) (optional — for LTV:CAC ratio)

What is Customer Lifetime Value?

Customer lifetime value (CLV) estimates total gross profit a customer generates over their relationship, from AOV, frequency, lifespan, and margin.

Use this page for unit economics and marketing budget caps. Customer acquisition cost (CAC) measures spend to acquire one customer; compare CLV:CAC ratio.

Churn rate informs retention; CLV monetizes retained customers.

CLV Formula

CLV = Average Purchase Value × Purchase Frequency × Customer Lifespan

Annual Customer Value = Average Purchase Value × Purchase Frequency

LTV:CAC Ratio = CLV ÷ CAC

Example

Avg Purchase Value = $120 | Frequency = 4/year | Lifespan = 3 years

Annual Value = $120 × 4 = $480/year

CLV = $120 × 4 × 3 = $1,440

Frequently Asked Questions

What is Customer Lifetime Value (CLV)?

CLV is the total revenue a business can expect from a single customer account throughout their relationship. It helps businesses decide how much to invest in acquiring and retaining customers.

How is CLV different from LTV?

CLV (Customer Lifetime Value) and LTV (Lifetime Value) are used interchangeably. Some models use LTV to refer to the gross margin-adjusted value, accounting for costs.

What is a good LTV:CAC ratio?

A healthy LTV:CAC ratio is 3:1 or higher. This means for every $1 spent acquiring a customer, you generate $3 in lifetime value. A ratio below 1:1 means you are losing money on every customer.

How can I increase CLV?

Increase average order value through upsells and bundles, improve purchase frequency with loyalty programs and email marketing, and extend customer lifespan through excellent service and retention strategies.

Common Mistakes

Using revenue instead of gross margin

CLV should be based on gross profit, not top-line revenue, to reflect the true value after cost of goods.

Overestimating customer lifespan

Average lifespan = 1 ÷ monthly churn rate. A 5% monthly churn means an average lifespan of only 20 months.

Using blended averages

Averaging across all customers obscures high-value segments that may warrant very different CAC limits.

Ignoring time value of money

For long lifespan estimates, discounted CLV (net present value) is more accurate than simple multiplication.

Not updating CLV models

CLV changes with pricing, churn, and product — recalculate at minimum quarterly for active businesses.
