CAC/LTV is a unit-economics check, not just a marketing KPI. The SBA market research guide highlights the need to understand customer demand before spending heavily, while the SBA startup cost guide keeps acquisition spend inside the full cost picture.
Include ad spend, sales tools, commissions, agency retainers, and campaign production when those costs directly support new customers.
Revenue LTV can look impressive while margin is thin. Gross-profit LTV is closer to the cash available to repay CAC.
If payback requires many orders, compare your assumptions with official expense guidance such as the IRS business expense resources.
A strong ratio is useful only when CAC is complete, gross margin is realistic, and the payback window matches your cash runway.
