Customer Lifetime Value (CLV) Calculator

In 2026, rising ad costs and increased competition mean you cannot rely on first-purchase profitability alone.

Understanding Customer Lifetime Value helps you:

• Know how much you can afford to spend on acquisition
• Improve retention strategies
• Make smarter scaling decisions

Without CLTV, growth becomes guesswork.

Businesses should calculate CLTV to understand long-term profitability. When you know your Customer Lifetime Value, you can:

• Set sustainable customer acquisition budgets
• Improve pricing models
• Identify your most valuable customer segments
• Predict revenue more accurately

A common Customer Lifetime Value formula is:

CLTV = Average Order Value × Purchase Frequency × Customer Lifespan

For subscription businesses, it may also be calculated as:

CLTV = Average Revenue Per User (ARPU) ÷ Churn Rate

Your Customer Lifetime Value Calculator applies these formulas automatically based on your inputs.

To calculate CLTV manually:

1. Calculate your Average Order Value (AOV)
2. Determine how often customers purchase per year
3. Estimate the average customer lifespan (in years)
4. Multiply all three numbers

Or simply use a Customer Lifetime Value Calculator to get instant results without manual calculations.

There is no universal number. A “good” Customer Lifetime Value depends on:

• Your industry
• Your pricing model
• Your margins
• Your acquisition costs

The key question is not just the CLTV number, it’s whether it supports profitable growth.

A good CLTV to CAC (Customer Acquisition Cost) ratio is typically 3:1.

This means you earn three times more from a customer than what you spent to acquire them.

If the ratio is below 1:1, you are losing money. If it’s too high (like 6:1 or more), you may be under-investing in growth.

Yes. This Customer Lifetime Value Calculator works for:

• SaaS businesses with recurring subscriptions
• Ecommerce brands with repeat purchases
• Service businesses with recurring contracts or renewals

Simply adjust the inputs to match your business model.

CLTV should be recalculated at least quarterly. If you are actively scaling paid ads, changing pricing, or launching new offers, review it monthly.

Customer behaviour changes over time. Your numbers should reflect that.
