Calculating Repeat Purchase Rate
RPR Formula
RPR = (Repeat Customers ÷ Total Customers) × 100
Example: 2,500 repeat purchasers out of 10,000 total customers = 25% RPR
Calculation Considerations
Time Window Selection
Choose a period that makes sense for your category:
- Grocery: 30-90 days
- Apparel: 6-12 months
- General retail: 12 months
- Big-ticket: 24+ months
Customer Definition
Be consistent about who counts as a "customer":
- All purchasers vs. identified members only
- Online + in-store vs. single channel
- Account for returns and refunds
- Household vs. individual level
Related Metrics
Purchase Frequency
Average number of purchases per customer per period. If 10,000 customers made 35,000 purchases, frequency = 3.5 purchases per customer.
Time Between Purchases
Average days between purchases for repeat buyers. Useful for timing re-engagement campaigns and identifying purchase cycle changes.
Second Purchase Rate
Specifically measures first-to-second purchase conversion. Often the hardest step—customers who make a second purchase are much more likely to make a third.
The Second Purchase Problem
Most churn happens before the second purchase. Focus onboarding and early engagement specifically on driving that critical second transaction.
Industry Benchmarks
| Industry | Typical RPR (Annual) | Top Performers |
|---|---|---|
| Grocery | 70-85% | 90%+ |
| Pharmacy/Health | 60-75% | 85%+ |
| Convenience/Fuel | 50-65% | 75%+ |
| Apparel/Fashion | 25-35% | 45%+ |
| General Retail | 20-30% | 40%+ |
| E-commerce (general) | 15-25% | 35%+ |
| Luxury/Big-ticket | 10-20% | 30%+ |
Member vs. Non-Member RPR
Loyalty program members typically show 20-50% higher repeat purchase rates than non-members. This represents both selection bias (loyal customers join programs) and program impact (programs drive repeat behavior).
Strategies to Improve RPR
- 1. Focus on first-to-second purchase. New customer onboarding programs, welcome series, and first-purchase follow-up offers drive the critical second purchase that predicts long-term loyalty.
- 2. Implement a loyalty program. Loyalty programs create reasons to return—points to earn, rewards to redeem, status to maintain, personalized offers to claim.
- 3. Personalize post-purchase communication. Follow up with relevant recommendations based on what customers bought. "You might also like..." drives return visits.
- 4. Create purchase triggers. Replenishment reminders, "back in stock" alerts, seasonal prompts, and expiring points notifications give customers reasons to return.
- 5. Offer subscription/auto-replenishment. For consumable products, subscription programs guarantee repeat purchases while adding convenience for customers.
- 6. Reduce friction. Saved payment methods, address books, wish lists, and easy reordering remove barriers to repeat purchases.
The Compound Effect
Improving repeat purchase rate compounds over time. A customer who returns once is more likely to return again. A 10% improvement in RPR can drive 20-30% increase in customer lifetime value.
