Acquisition Is Not the Win
Getting a paying user is only the start. If they cancel next month, you barely break even on acquisition cost. Retention is where indie apps become profitable.
This lesson focuses on keeping revenue, not just earning it once.
What Is Churn?
Churn is the percentage of users who stop paying in a period. A 10 percent monthly churn means you lose a tenth of your base every month — and must replace it just to stand still.
Calculating Churn
Churn rate is lost customers divided by starting customers.
function churnRate(start, lost) {
return (lost / start) * 100;
}
console.log(churnRate(200, 20) + '%');Lifetime Value (LTV)
LTV estimates total revenue from an average customer. A simple model: average revenue per user divided by churn rate.
function ltv(monthlyRevenue, monthlyChurn) {
return monthlyRevenue / monthlyChurn;
}
console.log(ltv(10, 0.05));LTV vs CAC
The golden ratio: LTV should exceed CAC (customer acquisition cost), ideally by 3x.
If you spend more to acquire than you earn back, growth burns cash. Lowering churn raises LTV directly.
Voluntary vs Involuntary Churn
Two kinds:
- Voluntary: user chooses to cancel
- Involuntary: payment fails (expired card)
Involuntary churn is often 20-40 percent of losses and is fixable with payment retries.
Dunning and Payment Retries
Dunning automatically retries failed payments and emails users to update cards. Most subscription platforms include it — turn it on.
It recovers revenue you already earned.
Onboarding Drives Retention
Users who reach their first aha moment early churn far less. Design onboarding to deliver value fast.
The strongest retention lever is a great first week.
Cancellation Flows
When users try to cancel, offer alternatives:
- Pause instead of cancel
- A discount to stay
- Downgrade to a cheaper tier
Always ask why — that feedback is gold.
Win-Back Campaigns
Churned users are warm leads. A win-back email weeks later — highlighting new features or a returning offer — can reactivate a meaningful share.
It is cheaper than acquiring someone brand new.
A Retention Playbook
Put it together:
- Track churn and LTV monthly
- Enable dunning for failed payments
- Nail the first-week aha moment
- Offer pause and discounts at cancellation
- Run win-back campaigns
Keep customers and profit follows.
Quick Check
Test your monetization retention knowledge.
Recap
You learned to protect revenue:
- Churn erodes your base; LTV measures customer value
- Aim for LTV at least 3x CAC
- Recover involuntary churn with dunning
- Strong onboarding and cancellation flows cut churn
- Win-back campaigns reactivate lost users
Retention is where indie apps turn profitable.
