Here's a shocking fact:
It costs 5-7x more to acquire a new customer than to retain an existing one.
Yet most startups focus almost exclusively on acquisition.
This guide shows you how to build a retention strategy that keeps customers for life.
Why Retention Matters
The Retention Math
Scenario A: Focus on Acquisition
- 100 customers
- 10% monthly churn
- 10 new customers/month
- After 1 year: 108 customers
Scenario B: Focus on Retention
- 100 customers
- 5% monthly churn
- 10 new customers/month
- After 1 year: 176 customers
Result: Same acquisition, but 63% more customers by reducing churn by 50%.
The Retention Revenue Impact
The Retention Multiplier:
Churn Rate | Monthly Revenue After 1 Year |
|---|---|
10% | 1.1x starting revenue |
2% | 3.6x starting revenue |
The Churn Cost
Example:
- Monthly revenue: $100,000
- Monthly churn: 7%
- Customers lost: 70
- Revenue lost: $7,000/month
- Annual revenue lost: $84,000
Reducing churn by 2% (to 5%):
- Annual revenue retained: $24,000+
