SaaS LTV: Customer Lifetime Value Calculation Guide explains SaaS LTV with the same definitions and calculation method used by the linked tools. Use the method for a consistent scenario, then verify any current rate, legal rule, or platform policy against the cited source.
Answer in brief
LTV = ARPU × gross margin percentage / customer churn rate
Scope and definitions
This guide owns the informational intent; linked calculator pages continue to own interactive calculator intent.
The guide supports SaaS LTV Calculator; Churn Rate Calculator; LTV:CAC Calculator. Keep the numerator, denominator, cost categories, fee base, and time period consistent from the first input through the final comparison.
Calculation method
| Step | Calculation or rule |
|---|---|
| 1 | LTV = ARPU × gross margin percentage / customer churn rate |
Formula / rule
LTV = ARPU × gross margin percentage / customer churn rate
Worked example
Monthly ARPU is $150, gross margin is 80%, and monthly customer churn is 2%. Simplified LTV is $6,000: $150 × 0.80 / 0.02. If churn rises to 3%, the same model produces $4,000, showing how sensitive LTV is to retention assumptions.
Practical reference
Record the relevant scenario fields together before calculating. The implementation brief calls for these comparison fields: Input, Example. Using one record prevents values from different periods or scopes from being mixed.
Common mistakes
- Using a different definition or time period from the one specified by the SaaS LTV method.
- Comparing outputs from SaaS LTV Calculator; Churn Rate Calculator; LTV:CAC Calculator without holding the shared assumptions constant.
- Treating a worked scenario as a universal target instead of testing the inputs that apply to the business.
- Relying on an undated secondary claim when the listed first-party or official source governs a current rate or rule.
Frequently asked questions
Should SaaS LTV use revenue or gross profit?
The answer depends on the scenario and assumptions. Use the stated method for SaaS LTV, then test the result with the linked calculators and verify any current rate or rule against the listed sources.
Is one divided by churn the same as customer lifetime?
SaaS LTV: Customer Lifetime Value Calculation Guide uses the defined method and scope above. Keep the calculation consistent with SaaS LTV Calculator; Churn Rate Calculator; LTV:CAC Calculator and do not treat the example as a universal recommendation.
Should I use cohort data instead?
The answer depends on the scenario and assumptions. Use the stated method for SaaS LTV, then test the result with the linked calculators and verify any current rate or rule against the listed sources.
How this guide was created and tested
- Method basis: the guide uses the same definitions and method boundaries as the linked calculator family and the audited implementation package.
- Validation coverage: the linked calculators currently contribute 6 audited release test vectors to the underlying calculation methods used by this guide.
- Source hierarchy: current rates, fees, laws, or platform rules prefer government and first-party sources; educational and industry references are supporting evidence rather than silent overrides.
- Automation and AI: automation or AI may assist drafting, organization, source grouping, and regression work, but it is not treated as an authoritative source and cannot replace the cited evidence or audited formula.
- Editorial responsibility: MIASIN S.R.O. controls publication, source policy, corrections, and release decisions. No named individual expert review is claimed unless a page explicitly identifies one.
