How CLV is calculated

Revenue per year = average order value x purchases per year x active customer share.

How CLV is calculated

  • Revenue per year = average order value x purchases per year x active customer share.
  • Profit per year = revenue x gross margin - annual support cost.
  • Profit LTV sums discounted yearly profit, then compares it with CAC for LTV:CAC and payback.
  • Target gap = target ratio x CAC - profit LTV when the current segment is below target.

Frequently asked questions

Should I use revenue LTV or profit LTV?

Profit LTV is usually better for acquisition decisions because it accounts for margin and support cost.

What is a healthy LTV:CAC ratio?

Many teams use 3:1 as a practical target, but the right ratio depends on cash flow, payback period, and business model.

Why include annual churn?

Churn reduces the active customer share each year, which makes long-term value more realistic than a flat lifespan assumption.

How should I use the scenario comparison?

Look at the best improvement lever first. It shows which change has the largest effect on net value under the current assumptions.
