# CLV 180: 180-Day Cohort Lifetime Value

> Track total revenue from all customers within 180 days of first purchase. Learn the formula, see examples, and measure 6-month cohort revenue performance.

<Tip>
  Total revenue generated by all customers within 180 days (6 months) of their first purchase.

## Formula

<Info>
  **CLV 180** = **SUM** ( Customer Revenue ) **WHERE** days since first order ≤ 180

## Example

Analyzing customers acquired in January shows **\$127,800** in CLV 180:

| Cohort   | Customers | First Orders | Repeat Orders (180d) | CLV 180   |
| -------- | --------- | ------------ | -------------------- | --------- |
| January  | 1,200     | \$72,000     | \$55,800             | \$127,800 |
| February | 1,450     | \$87,000     | \$71,050             | \$158,050 |
| March    | 1,100     | \$66,000     | \$52,800             | \$118,800 |

The January cohort's CLV 180 of \$127,800 represents all revenue from those 1,200 customers within 6 months of their first purchase.

## How It Works

CLV 180 sums all revenue from each customer's orders within 180 days of their first purchase. This includes their initial order plus any repeat purchases made in that window. Unlike [LTV 180](/reference/metrics/orders/ltv/ltv-180) which calculates an average per customer, CLV 180 shows the total dollar value generated by the entire cohort—making it ideal for measuring aggregate cohort performance and ROI.

## When to Use

| Scenario                       | Action                                                            |
| ------------------------------ | ----------------------------------------------------------------- |
| Measuring cohort ROI           | Compare CLV 180 against total acquisition spend for the cohort    |
| Budgeting acquisition spend    | Set monthly acquisition budgets based on expected CLV 180 returns |
| Evaluating marketing campaigns | Track CLV 180 for customers acquired during specific campaigns    |
| Forecasting 6-month revenue    | Project total revenue from newly acquired customer cohorts        |
