Definition
LTV is the expected gross profit from a customer over their lifetime, based on revenue per account, churn, and margin.
Why it matters
LTV guides acquisition spend, pricing decisions, and product investment by showing long-term profitability. It is most useful when the assumptions behind it are explicit and segment-specific.
What LTV does and does not tell you
LTV tells you how much value a customer can generate over time. It does not tell you how quickly the business recovers cash, and it does not tell you whether the input assumptions were too optimistic.
If the model relies on smooth averages, LTV can look strong while a weak cohort still drags the real business down.
Pricing implications
Higher revenue per account and higher gross margin increase LTV; high churn can destroy it quickly. A pricing change that improves expansion or retention should show up here, but only if the underlying cohort logic is clean.
Measurement tips
Use consistent time windows, segment by plan, and validate with cohort retention data. A useful LTV model is one the team can explain without hand-waving the churn assumption.
Common mistakes
- Using revenue instead of gross profit.
- Mixing logo churn and revenue churn in the same formula.
- Building one company-wide LTV for segments with different onboarding or support costs.
- Treating a high LTV as safe when CAC payback is still too slow.
How to use it with PricingNest tools
Use the LTV Calculator to rebuild the revenue, margin, and churn assumptions. Use the Break Even CAC Calculator when the question becomes how much acquisition cost the model can support. Then check the CAC Payback Period to make sure the cash recovery story is also healthy.
