Understanding Retention Rate

The Retention Formula

```

Customer Retention Rate = ((End Customers - New Customers) ÷ Start Customers) × 100

Example:

Start of month: 1,000 customers

End of month: 950 customers

New customers: 200

Retention rate: ((950 - 200) ÷ 1,000) × 100 = 75%

```

Why Subtract New Customers?

You want to measure how many existing customers you kept, not overall customer count. Including new customers inflates the metric and masks retention problems.

Timeframe Considerations

Monthly Retention:

Best for subscriptions

Quick feedback loop

Enables rapid iteration

Quarterly Retention:

Good for 30-60 day reorder cycles

Smooths monthly fluctuations

Balances speed and accuracy

Annual Retention:

Standard for most eCommerce

Industry benchmarks available

Better for seasonal businesses

Retention vs Churn

The Relationship

```

Retention Rate + Churn Rate = 100%

If Retention = 70%, then Churn = 30%

If Retention = 85%, then Churn = 15%

```

Which to Track?

Track Both!

Retention shows success (customers kept)

Churn shows problems (customers lost)

Both provide complete picture

Focus on Retention for:

Positive framing

Team motivation

Growth mindset

Focus on Churn for:

Problem identification

Urgency creation

Root cause analysis

The Value of Retention

Revenue Impact

Example: 10% Retention Improvement

```

Current State:

10,000 customers

70% annual retention = 7,000 retained

$500 annual revenue per customer

Retained revenue: $3,500,000

Improved State (80% retention):

10,000 customers

80% annual retention = 8,000 retained

$500 annual revenue per customer

Retained revenue: $4,000,000

Additional Revenue: $500,000 annually

```

Lifetime Value Multiplier

Retention's Compound Effect:

```

Customer A (50% annual retention):

Lifetime: 2 years

Yearly spend: $500

LTV: $1,000

Customer B (75% annual retention):

Lifetime: 4 years

Yearly spend: $500

LTV: $2,000

2x retention = 2x lifetime value

```

Profit Margin Impact

Why Retained Customers Are More Profitable:

No acquisition cost: $0 vs $20-$100 CAC

Higher AOV: 2x higher average order

More frequent purchases: 3-4x more often

Lower service costs: Familiar with products

Free marketing: Referrals and reviews

```

New Customer Profit:

Revenue: $100

CAC: $40

Cost of goods: $30

Service costs: $15

Profit: $15 (15% margin)

Retained Customer Profit:

Revenue: $150 (50% higher AOV)

CAC: $0

Cost of goods: $45

Service costs: $8 (lower)

Profit: $97 (65% margin)

4.3x more profitable!

```

Retention Calculation Examples

Example 1: Monthly Retention

```

March 1: 5,000 customers

March 31: 5,200 customers

New customers in March: 450

Retention Calculation:

Retained = 5,200 - 450 = 4,750

Retention rate = (4,750 ÷ 5,000) × 100 = 95%

Churn rate = 5% (lost 250 customers)

```

Example 2: Annual Retention

```

Jan 1, 2024: 10,000 customers

Dec 31, 2024: 8,500 customers

New customers in 2024: 3,000

Retention Calculation:

Retained = 8,500 - 3,000 = 5,500

Retention rate = (5,500 ÷ 10,000) × 100 = 55%

Churn rate = 45% (lost 4,500 customers)

```

Example 3: Cohort Retention

Track January 2024 acquisition cohort:

```

Month 0 (Jan): 1,000 customers (baseline)

Month 1 (Feb): 900 retained (90% retention)

Month 3 (Apr): 750 retained (75% retention)

Month 6 (Jul): 600 retained (60% retention)

Month 12 (Jan 2025): 450 retained (45% retention)

```

Core Metrics

Segment by cohort and customer type

Repeat Purchase Rate (RPR):

% of customers who buy again

Measures actual repurchase behavior

Industry benchmark: 25-50%

Customer Lifetime (Avg):

How long customers stay active

Inverse of churn rate

Monthly churn 5% = 20 month lifetime

Purchase Frequency:

Orders per customer per period

Target: 2-4x annually for eCommerce

Increases with retention

Advanced Metrics

Cohort Retention Curves:

Track each acquisition month separately

Identify improving/declining trends

Compare acquisition channels

Revenue Retention:

% of revenue retained (not just customers)

Accounts for spending changes

Can exceed 100% with upsells

Net Revenue Retention (NRR):

Revenue retention + expansion - contraction

Shows if retained customers spend more

Target: 100%+ (growth from existing customers)

Monthly vs Annual Retention

Converting Monthly to Annual

```

Annual Retention ≈ (Monthly Retention)^12

Examples:

95% monthly → 54% annual retention

90% monthly → 28% annual retention

85% monthly → 14% annual retention

```

The Compounding Effect

Even small monthly losses compound:

99% monthly = 89% annual (11% lost)

95% monthly = 54% annual (46% lost!)

90% monthly = 28% annual (72% lost!!)

This is why subscription businesses obsess over monthly retention!
