LTV to CAC Ratio Ecommerce

Yes — this tool takes your LTV and CAC as direct inputs; it doesn't compute either one for you. Use the Lifetime Value Calculator and Customer Acquisition Cost Calculator first, then enter both results here.

3:1 or higher is the commonly cited benchmark for sustainable growth. This tool bands the result as healthy at 3:1+, break-even at 1:1-3:1 (reduce CAC or increase LTV), and losing money below 1:1.

It means you're spending more to acquire each customer than they're worth over their lifetime — a signal to either cut acquisition costs, raise retention/order value to lift LTV, or reconsider the channel.

Very high ratios (e.g. 8:1+) can sometimes mean you're underinvesting in growth — this tool doesn't flag that case, it only bands the low end.
