Repeat Purchase Rate

CMO CFO VP Marketing COO

Repeat Purchase Rate measures the percentage of customers who make more than one purchase within a defined time period, indicating brand loyalty and product satisfaction in transactional or e-commerce businesses. A high repeat purchase rate reduces CAC per order over time (acquisition cost is amortized across multiple purchases) and is the primary driver of LTV in non-subscription models.

Increasing repeat purchase rate through loyalty programs, personalized re-engagement, and product quality improvements is typically more cost-efficient than acquiring new customers.

Common Questions About Repeat Purchase Rate

What is the relationship between repeat purchase rate and LTV?

In non-subscription businesses, LTV is driven primarily by how many times a customer buys and at what value each time. Repeat purchase rate determines purchase frequency. A customer who buys three times instead of once has 3× the LTV from frequency alone. Improving repeat purchase rate from 20% to 30% can increase average cohort LTV by 25%–50% depending on AOV and purchase cadence.

How do I increase repeat purchase rate?

The most effective tactics are: personalized re-engagement emails timed to the expected repurchase window, post-purchase follow-up with complementary product recommendations, loyalty programs that reward purchase frequency, subscription or auto-replenishment options for consumable products, and unboxing and product experience improvements that create memorable first impressions that drive return visits.

What is the second purchase window and why does it matter?

Research in e-commerce shows that customers who make a second purchase are far more likely to make a third, fourth, and beyond. The window after the first purchase is therefore critical: re-engaging customers within 30–60 days of their first order (before they forget the brand or buy from a competitor) dramatically increases the lifetime relationship. Many brands run specific post-purchase sequences targeted at converting one-time buyers into repeat customers.

How does repeat purchase rate differ by acquisition channel?

Customers acquired through organic search, word-of-mouth referral, and brand advertising tend to show higher repeat purchase rates because they arrived with higher brand affinity. Performance-marketing customers (especially from discount channels or deal aggregators) often show lower repeat purchase rates because their acquisition was price-driven rather than brand-driven. Tracking repeat purchase rate by acquisition source helps optimize channel mix for long-term LTV.
