Customer Lifetime Value (CLV) Calculator

Average revenue per customer per month (e.g. subscription price)

How many times a customer purchases per year (12 = monthly SaaS)

Average number of years a customer stays before churning

Revenue minus cost of goods sold, as a percentage (SaaS average: 70-80%)

Annual discount rate to calculate present value (typically 8-12%)

Total cost to acquire one customer

Discounted CLV

€2,068

CLV:CAC ratio of 4.1:1. Below 3:1, growth gets expensive.

How it works

This calculator computes both nominal and discounted CLV, breaks down revenue by period, and evaluates your CLV:CAC ratio against industry benchmarks. Enter your metrics below to see exactly where your unit economics stand.

Why calculate customer lifetime value?

  1. It caps what you can pay to acquire

    Without CLV there is no way to tell whether your acquisition cost is an investment or a leak.

  2. It is discounted to present value

    A euro collected three years from now is worth less than one collected today, so the calculation applies your discount rate year by year.

  3. Making the relationship last moves everything

    CLV grows with lifetime, and lifetime depends on the customer getting answers when they need them.

Frequently asked questions

Customer Lifetime Value (CLV) is the total revenue a business can expect from a single customer account throughout their entire relationship. It factors in average purchase value, purchase frequency, customer lifespan, and profit margins. CLV helps businesses decide how much to invest in acquiring and retaining customers.

The standard CLV formula is: CLV = Average Purchase Value × Purchase Frequency × Customer Lifespan × Gross Margin. For a more accurate figure, you can apply a discount rate to account for the time value of money. For example, a SaaS customer paying €99/month for 3 years with 70% margin has a CLV of €2,494.

A CLV:CAC ratio of 3:1 or higher is considered healthy — meaning you earn 3x what you spend to acquire a customer. A ratio below 2:1 suggests you're overspending on acquisition. Above 5:1 may indicate you're under-investing in growth. The ideal range for SaaS businesses is 3:1 to 5:1.

Five proven strategies: (1) Reduce churn with proactive support and AI chatbots, (2) Increase purchase frequency through upselling and cross-selling, (3) Improve gross margins by automating support costs, (4) Extend customer lifespan with loyalty programs and excellent onboarding, (5) Raise average order value with premium tiers and add-ons.

Average CLV in SaaS varies widely by segment. SMB SaaS typically sees CLV of $1,000-$5,000. Mid-market ranges from $10,000-$50,000. Enterprise SaaS can exceed $200,000. The median across all SaaS is roughly $243/month in revenue per customer, but CLV depends heavily on churn rate and expansion revenue.
