Lifetimely: Using Cohort Analysis with the Lifetime Value Report

At a glance: Once you understand how to read the LTV Report, you can use cohort analysis to answer real business questions — from setting acquisition budgets to identifying which products drive the most long-term value. This article walks through six practical use cases.

1. Plan customer acquisition budgets

To scale confidently, you need to know how much you can afford to spend to acquire a customer. Cohort analysis shows you how much revenue a new customer generates over time — and when that revenue exceeds your acquisition cost.

If you're not profitable on the first purchase, start by finding your CAC payback period — the point at which accumulated customer revenue covers what you spent to acquire them.

Use the Accumulated Gross Margin metric on the LTV Report to see gross profit per cohort over time.
Compare against your CAC to find the month when each cohort breaks even.

💡 Tip: Typical CAC payback periods vary by category. For consumables like supplements, skincare, and food: 3–6 months is common, with top brands achieving under 3. For non-consumables: 6–12 months is more typical.

2. Monitor customer behaviour after scaling

When you increase ad spend or launch a new acquisition channel, the LTV Report lets you check whether the new customers you're acquiring behave like your existing ones — or differently.

Use the Accumulated Gross Margin metric and filter by source/medium or marketing channel.
Compare CAC and revenue across cohorts to see whether new customers are tracking better, worse, or in line with historical ones.

This is especially useful for validating assumptions after a campaign change or a shift in channel mix.

3. Identify your most valuable products

Many DTC brands have a hero product — one that brings customers in and drives long-term repurchases. Cohort analysis helps you find it.

Use the Accumulated Sales per Customer metric on the LTV Report, filtered by first-order product or first-order product category.
Use the Repurchase Rate Report filtered by products or collections to see which products drive the most repeat purchases.

4. Identify your most valuable customer segments

Geography, acquisition channel, and purchase behaviour all affect long-term value. Use cohort filters to compare segments.

Use the Accumulated Sales per Customer metric on the LTV Report, filtered by country.
Use the Repurchase Rate Report filtered by country or collection to see which segments repurchase most often.

5. Monitor lifetime value trends over time

Are your retention efforts actually working? Use the LTV Report to track whether customer value is improving across cohorts.

Use the Accumulated Sales per Customer metric and compare cohorts across weeks, months, or years.
Focus on 3, 6, and 24-month windows to understand short, medium, and long-term retention trends.

6. Evaluate campaign and channel performance

Customers acquired through different channels tend to behave differently over time. The LTV Report lets you measure that difference with real data.

Filter the Accumulated Sales per Customer metric by first/last touch marketing channel, source/medium, tags, or discount codes.
Once filtered, compare cohorts across: accumulated sales per customer, accumulated gross margin per customer, total repurchasing customers, and accumulated orders per customer.

📚 Example: A supplement brand runs a sample promotion where customers pay only shipping. Use the LTV Report — filtered by the discount code used — to track the long-term value of those customers and determine whether the promotion was worth it.

💡 Tip: Weekly data tends to give the sharpest view of recent marketing performance in CPG. But don't skip long-term yearly analysis — it reveals how many customers genuinely return to your brand over time.
