Use this calculator to calculate customer lifetime value for a SaaS business using a simple, practical formula. It is designed for quick planning, reporting, and scenario checks when you need a clear number without building a spreadsheet.

What this calculator does

The Customer Lifetime Value Calculator Advanced turns a small set of SaaS inputs into one decision-ready output.

It uses:

ARPU
churn rate
comparison period
standard SaaS assumptions

The result helps you understand customer lifetime value in a consistent way so you can compare periods, plans, segments, or growth scenarios. It is an estimate for planning purposes, not accounting, tax, legal, or investment advice.

How to use the customer lifetime value calculator advanced

Enter the required inputs using the same reporting period and currency basis. For example, do not mix monthly revenue with annual customer counts unless the formula specifically calls for it.

Review the output alongside the operating context behind the number. Use this with the LTV to CAC Ratio Calculator Advanced, Churn Rate Calculator Advanced, and ARPU Calculator Advanced.

Customer Lifetime Value Calculator Formula

LTV = ARPU / churn rate

Use percentages as percentages in the calculator fields. When doing the calculation manually, convert percentage rates to decimals where needed.

Example calculation

If:

Scenario input 1 = 100
Scenario input 2 = 50
Scenario period = 1 month
Reporting basis = SaaS operating metric

Then:

If ARPU is 100 and churn is 5%, LTV is 2,000

This simple example keeps the numbers round so the relationship between the inputs and output is easy to see.

What is customer lifetime value?

Customer lifetime value estimates the revenue expected from an average customer over their lifetime.

The exact definition should stay consistent across reports. Changing the definition from one month to the next can make the trend misleading even when the formula is mathematically correct.

Why customer lifetime value matters

LTV helps judge whether acquisition cost is sustainable. A low LTV may point to pricing, retention, or onboarding problems.

A single result should not be read in isolation. Compare it with prior periods, customer segments, acquisition channels, plan types, and the business model behind the number.

When to use this calculator

Use this calculator when you want to:

prepare a monthly SaaS metrics review
compare performance across periods
test a simple planning scenario
sanity-check a board or investor metric

Common mistakes

Common mistakes include:

mixing monthly and annual inputs
using inconsistent customer definitions
ignoring churn, contraction, or expansion context
treating one period as a long-term trend

FAQs

Is this calculator exact?

It gives a formula-based estimate. Your internal reporting may use more detailed definitions, exclusions, or accounting rules.

What period should I use?

Use the period that matches the metric. Monthly recurring metrics should use monthly inputs, while annual metrics should use annualized inputs.

Can I compare this across customer segments?

Yes, if each segment uses the same definition and reporting period.

Should this replace financial reporting?

No. Use it for planning and analysis, then reconcile important figures with your source systems.
