What this calculator does
The Client LTV Calculator gives agencies a clear estimate of long-term revenue value for each account. Lifetime value is essential for understanding how much acquisition and retention investment is sustainable. This tool combines monthly retainer, average retention period, and churn assumptions to model expected LTV quickly. It can be used in strategic planning, onboarding economics, and account health reviews where leaders need to quantify the impact of retention improvements. Agencies can also compare client segments to identify which profiles generate the strongest long-term return. With better visibility into LTV, growth decisions become more disciplined and less reactive.

Why this matters for agencies
LTV helps agencies connect retention performance to long-term revenue outcomes. Even small improvements in churn can produce meaningful upside across the portfolio.
Frequently asked questions
How do agencies calculate client lifetime value?
A common approach multiplies monthly retainer by expected retention period, then adjusts for churn and margin.
Why should LTV include gross margin?
Revenue-only LTV can overstate value. Margin-adjusted LTV better reflects economic contribution.
How can I improve client LTV?
Improve onboarding quality, reporting transparency, and account outcomes to reduce churn and extend retention.
What churn rate should agencies target?
Targets vary, but many healthy agencies aim for low single-digit monthly churn and strong annual retention.
