ltv / max(cac, 0.01)常见问题
What is a good LTV to CAC ratio?
A ratio of 3:1 or higher is typically considered healthy, meaning the customer value is three times the acquisition cost. Ratios below 1 indicate you're losing money on each customer.
How is LTV calculated?
LTV is usually calculated as average purchase value × purchase frequency × customer lifespan. This calculator takes LTV as an input, so you need to compute it separately.
What if my CAC is zero?
The calculator uses a minimum CAC of 0.01 to avoid division by zero, but a zero CAC is unrealistic. Ensure you enter a positive CAC.

公式
此计算器背后的数学公式，供您核对结果。
LTV to CAC Ratio
This ratio compares the total revenue a customer generates over their lifetime to the cost of acquiring them. A higher ratio indicates more efficient acquisition.
Example:
Input: LTV = $500, CAC = $100
Calculation: 500 / 100
Result: 5.0x
实际应用场景
此计算在日常生活中的应用。
Evaluate Marketing ROI
Determine if your marketing spend is justified by the long-term value of acquired customers.
Example: If LTV is $600 and CAC is $150, ratio is 4x, indicating good ROI.
Set Acquisition Budgets
Use the ratio to decide how much you can afford to spend on acquiring a customer while staying profitable.
Example: If target ratio is 3 and LTV is $900, max CAC is $300.
Compare Customer Segments
Calculate the ratio for different customer groups to identify which segments are most profitable.
Example: Compare high-value vs. low-value customers to allocate resources.
提示与常见错误
Tips
