What Is a Cohort?

A cohort is a group of customers that share a start point, usually the month they first subscribed.

Tracking cohorts over time reveals whether newer customers behave better or worse than older ones.

Why Cohorts Beat Averages

A single churn average hides trends. Cohort tables show retention curves per signup month, exposing whether product changes improved stickiness.

Building a Cohort Key

Bucket each customer by the year-month of their first successful charge.

function cohortKey(firstChargeISO) {
  return firstChargeISO.slice(0, 7); // YYYY-MM
}
console.log(cohortKey('2026-03-14T10:00:00Z'));

Retention Matrix

For each cohort, count how many customers are still active in month 0, 1, 2, and so on. The result is a triangular matrix.

Rows = cohorts
Columns = months since signup

Computing Retention Percentage

Divide active customers in month N by the cohort's original size.

function retention(active, cohortSize) {
  return cohortSize === 0 ? 0 : Math.round(active / cohortSize * 100);
}
console.log(retention(72, 100) + '%');

Defining Lifetime Value

LTV estimates total revenue a customer brings before churning. A simple model is:

LTV = ARPU / churn rate

Where ARPU is average revenue per user per period.

Calculating ARPU

Average Revenue Per User divides total recurring revenue by active customers.

function arpu(monthlyRevenueCents, activeCustomers) {
  return activeCustomers ? monthlyRevenueCents / activeCustomers / 100 : 0;
}
console.log(arpu(4800000, 1200)); // dollars

Estimating LTV

Combine ARPU and churn to project lifetime value.

function ltv(arpu, monthlyChurnRate) {
  return monthlyChurnRate > 0 ? arpu / monthlyChurnRate : Infinity;
}
console.log(ltv(40, 0.05)); // 800

Pulling the Data from Stripe

Use the Subscriptions and Invoices APIs (or a synced data warehouse) to source signup dates, paid amounts, and cancellation dates that feed these calculations.

Acting on the Numbers

High LTV with weak early retention suggests onboarding fixes. Low LTV with strong retention suggests pricing or upsell opportunities.

Compare LTV to CAC (acquisition cost)
A healthy SaaS targets LTV/CAC above 3

Refining the Model

Advanced LTV uses discounting, segment-specific churn, and predicted expansion revenue. Start simple, then layer in nuance as data grows.

Quick Check

Check your grasp of cohorts and LTV.

Recap

You learned to group customers into cohorts, build a retention matrix, and estimate LTV from ARPU and churn. These metrics turn raw Stripe data into strategic decisions.
