How it works
CLV = Average Purchase × Frequency × Lifespan × Margin. The max acquisition cost is typically CLV ÷ 3 for a healthy 3:1 return ratio. Business financial metrics tell you whether your company is healthy, growing, or in trouble. Profit margin, cash flow, and break-even point are the three numbers every business owner should know by heart. These metrics change monthly, so review them regularly rather than once a year when your accountant sends the tax return.

- Start with the default values to see a baseline result, then change one input at a time to understand which factor matters most for your outcome.
- Replace every default with your actual number — estimates and rules of thumb produce estimates, not answers. Pull your real figures from pay stubs, statements, or account dashboards.
- Run the numbers quarterly, not annually. Tax brackets, revenue, and expenses shift throughout the year, and adjusting early is far cheaper than correcting at year-end.
Frequently asked questions
What is a good CLV to CAC ratio?
A ratio of 3:1 or higher is considered healthy. This means you earn $3 for every $1 spent on customer acquisition. Below 1:1 means you are losing money on every customer.
How accurate are the calculator results?
The math is exact — the same formulas a financial professional would use by hand. The precision of the output depends entirely on how realistic your inputs are. Use your actual numbers rather than estimates when possible. The defaults are reasonable starting points, but your real income, rates, and timeline will produce a different result.
What should I enter for average purchase value?
Enter your actual average purchase value value. The default of 100 dollars is a common starting point, but replace it with your real figure for an accurate result.
