LTV:CAC Ratio Calculator
See whether your customers are worth more than they cost to acquire. The LTV:CAC ratio is one of the clearest signals of profitable, sustainable growth.
Calculate your LTV:CAC ratio
The ratio equals lifetime value divided by customer acquisition cost, shown as X to 1. A 3:1 ratio is a common healthy benchmark, while below 1:1 means you lose money on every customer.

How the LTV:CAC ratio works
Two numbers tell you if acquisition pays off.
Enter your lifetime value
Add your LTV, or use lifetime gross profit for a stricter view that accounts for the cost of serving each customer. Gross profit gives the more honest ratio.
Enter your acquisition cost
Add your fully loaded CAC, including ad spend, sales and marketing labor, and tools. An incomplete CAC makes the ratio look better than it is.
Read your ratio
We divide LTV by CAC and show it as X to 1. Higher is better up to a point, while a very high ratio can mean you are underinvesting in growth.
Frequently Asked Questions
Common questions about the LTV:CAC ratio.
The LTV:CAC ratio compares the lifetime value of a customer to the cost of acquiring them. It is written as X to 1, where the number shows how many dollars of value you get for every dollar of acquisition cost. It is a fast read on whether your growth is profitable.
A 3:1 ratio is the classic healthy benchmark, meaning you earn three dollars of value for every dollar spent to acquire a customer. Below 1:1 you lose money on every customer. Much above 3:1 can signal that you are leaving growth on the table by underspending.
The 3:1 benchmark works well for steady, balanced growth, but some operators deliberately target far higher ratios before scaling ad spend. Service businesses in particular often push for around 8:1 so each customer is highly profitable, which gives them a wide buffer to spend aggressively and still win. Once the ratio is that strong, they pour more into acquisition to grow fast.
You can improve the ratio from both sides. Raise LTV with better pricing, upsells, and lower churn, and lower CAC by improving targeting, conversion, and sales efficiency. Even small gains on each side compound into a stronger ratio over time.
