Customer Lifetime Value Calculator for Solopreneurs
Calculate customer lifetime revenue, gross-profit CLV, LTV-to-CAC ratio, and acquisition payback from recurring revenue, margin, retention, and CAC.
By Solopreneurship WikiReviewed September 2026
Wiki note: Customer lifetime value should be measured in gross profit, not only revenue, and compared with the cost and time required to acquire the customer.
The calculator estimates the economic value of an average recurring customer using revenue, gross margin, and retained months. It then compares gross-profit CLV with customer acquisition cost (CAC).

Calculate your result
Change the example assumptions to match your situation. Use consistent units and the same currency throughout.
Calculations run in your browser. Nothing is submitted.
Your result will appear here.
Enter your assumptions and select “Calculate result.”
Use source data where possible, record the date of your assumptions, and keep all monetary inputs in the selected currency. A precise-looking answer is only as reliable as the inputs behind it.
How to interpret the result
A strong ratio does not excuse poor cash flow. Check payback time, churn cohorts, capacity, and the delay between acquisition spending and collected cash. Segment customers when retention or margins differ materially.
Stress-test the decision
Run a conservative case, an expected case, and an optimistic case. Change one important assumption at a time so you can see what actually drives the answer. Define the action you will take if the conservative case occurs.
Worked example
A subscription produces 250 per customer each month at 75% gross margin. Average retention is 14 months and CAC is 700. The tool separates lifetime revenue from gross-profit value and estimates CAC payback.
Replace every example value with evidence from your own accounts, time records, quotes, contracts, or customer data. Save the result alongside those sources so it can be reviewed later.
Limitations
Averages can hide new-customer cohorts, expansion revenue, refunds, discounting, churn timing, and service labor. Early businesses with little retention data should use a cautious range.
