CLV : CAC rule of thumb: Aim for 3:1 or better. Below 3:1 means you're working too hard for each client. Above 5:1 may mean you should spend more on growth.

How to Use This Calculator

Enter your current client count and average monthly revenue per client. For churn, use the trailing 6-12 month average, not last month. Single-month churn is noisy; the rolling average tells the story.

Gross margin per client should be what you keep after direct delivery cost but before overhead. Use 50-60% for typical agency work. Acquisition cost is total sales and marketing spend over a period, divided by number of new clients acquired in that period.

The output shows annual churn (which compounds, so it's always higher than 12x monthly), average client lifetime, CLV, CLV:CAC ratio, and annualized revenue lost to churn. The last number is usually the wake-up call.

Key Insights

  • Churn compounds. 3% monthly is 30% annually, not 36%. Still painful, but slightly less painful than linear math suggests.
  • CLV:CAC tells the growth story. Below 3:1 you're overspending to acquire. Above 5:1 you may be underinvesting in growth.
  • Retention beats acquisition. Cutting churn from 5% to 3% doubles average lifetime and CLV. Compare that to what it takes to double new sales.
  • Watch concentration. Average churn hides risk when one client is 30% of revenue. Model your top 3 clients leaving separately.

Frequently Asked Questions

What is a healthy churn rate for an agency?

Agency benchmarks: 1-2% monthly churn is best-in-class, 2-3% is healthy, 3-5% needs attention, 5%+ is critical. Monthly churn compounds annually; 3% monthly churn is roughly 30% annual churn, which means you're replacing almost a third of your client base just to stay flat.

How do I calculate client lifetime value?

CLV = average client lifetime (months) x average monthly revenue per client x gross margin percent. Average lifetime is 1 / monthly churn rate. So if monthly churn is 3% (0.03), average lifetime is 33 months. At $4,500 monthly revenue and 55% gross margin, CLV is 33 x 4,500 x 0.55 = $81,675.

What is a good CLV:CAC ratio?

Aim for 3:1 or better. Below 3:1 means you're spending too much to acquire clients relative to what they're worth. Above 5:1 may mean you're underinvesting in growth and could spend more on sales and marketing to accelerate. Target 3-5:1 for a balanced growth engine.

Why does small monthly churn add up so fast?

Churn compounds. At 3% monthly churn, 30% of clients churn per year. On a 40-client roster, that's 12 clients per year you need to replace just to stay even. If each client is worth $54k/year, that's $648k of annual revenue that has to come from new sales before you grow at all.

How do I reduce agency churn?

Biggest levers: better onboarding (first 60 days sets trajectory), quarterly business reviews (catch dissatisfaction early), account manager continuity (client-side contact changes are a top churn trigger), scope expansion before renewal (engaged clients churn less), and clear reporting that proves ROI.
