Customer Lifetime Value (LTV) tells you how much profit a customer generates over time. But to really understand what drives LTV, you need to zoom in on the behaviors that expand customer value.
One of the most powerful is Repeat Purchase Rate (RPR).
What Is Repeat Purchase Rate?
Repeat Purchase Rate measures the percentage of customers who buy more than once within a given timeframe.
The formula:
RPR = # of Customers Who Purchased More Than Once / Total # of Customers
For example:
Total new customers in Q1 = 1,000
Customers who placed 2+ orders within 12 months = 320
RPR = 320 / 1000 = 32%
👉 In this case, nearly one-third of customers came back for at least a second order.
Why the Second Order Is Critical
While RPR tracks all repeat buyers, the most important milestone is the second order.
Why?
Customers who place a second order are far more likely to become long-term buyers.
The second order often accelerates payback by multiplying gross profit faster.
Cohort curves typically show the largest drop-off between first and second orders.
👉 In practice: moving a customer from one purchase to two is often the difference between a money-losing cohort and a profitable one.
Cohort Curves: RPR in Action
Let’s look at a cohort of 1,000 new customers acquired in January.
| Month | Customers Remaining Active | Repeat Purchasers Added | Cumulative RPR |
|---|---|---|---|
| 0 (initial) | 1,000 | – | 0% |
| 1 | 700 | 120 | 12% |
| 3 | 550 | 180 | 30% |
| 6 | 400 | 50 | 35% |
| 12 | 320 | – | 32% |
👉 Insight:
The biggest jump in RPR happened within the first 90 days.
After that, growth in repeat buyers slowed.
This shows the importance of post-purchase nurturing early in the lifecycle.
Why RPR Matters
1. It Accelerates Payback
If nCAC is $200 and first-order gross profit is only $60, you’re still $140 in the hole. But if 30% of customers reorder within 60 days, you may recover acquisition cost far faster.
2. It Drives LTV Growth
LTV is a function of AOV × purchase frequency × margin. RPR directly boosts purchase frequency and therefore lifetime value.
3. It Predicts Customer Quality
Not all channels deliver the same retention. A low RPR on TikTok vs. a higher RPR on Google shows which source is bringing in stickier customers.
4. It Improves Cash Flow
High RPR reduces reliance on continuous new-customer acquisition, easing pressure on ad spend.
Benchmarks: What’s a “Good” RPR?
Benchmarks vary widely by industry, but some general patterns:
Subscription / continuity products: RPR 50%+ within 90 days.
Consumables (skincare, supplements, coffee): RPR 30–40% within 90 days.
Durables (apparel, electronics): Lower RPRs, often 15–25% annually, but higher AOV per repeat purchase.
The key is not chasing a universal number — it’s tracking your own cohorts over time and improving RPR relative to your baseline.
How to Improve RPR
1. Nail the Post-Purchase Experience
Fast shipping, clear communication, and a quality unboxing build trust.
Customer service speed and resolution drive repeat intent.
2. Create Early Reorder Incentives
Offer time-sensitive discounts or loyalty points for reordering within 30–60 days.
Use auto-replenishment reminders for consumables.
3. Build Retention Flows
Automated email/SMS post-purchase sequences.
Personalized product recommendations for second orders.
4. Introduce Subscriptions
Convert one-time buyers into recurring customers with discounts or perks.
5. Reward Loyalty
Offer status tiers or perks for multiple purchases.
Make the second order feel like the start of a relationship, not just another transaction.
Common Pitfalls
1. Only Tracking Revenue
Revenue can grow even if RPR falls — because AOV rises. Always track customer counts, not just dollars.
2. Ignoring Timing
A customer who reorders in 30 days is more valuable than one who reorders after a year. Payback windows depend on early repeat behavior.
3. Treating All Customers the Same
Different cohorts may have different RPR curves. Paid social buyers may reorder less than organic buyers. Segment to see the truth.
4. Over-Discounting
Driving repeat purchases with excessive discounts can improve RPR but hurt contribution margin. Balance matters.
Case Study: Beverage Brand
A beverage brand tracked RPR across cohorts acquired via Meta vs. Google.
Meta Cohort:
90-day RPR = 18%
12-month RPR = 30%
LTV after 12 months = $180
Google Cohort:
90-day RPR = 28%
12-month RPR = 42%
LTV after 12 months = $260
👉 Insight:
Google drove fewer customers at a higher nCAC, but RPR was stronger, resulting in higher LTV per customer.
The Bottom Line
RPR measures the share of customers who buy again.
The second order is the turning point that separates one-time buyers from long-term customers.
Improving RPR accelerates payback, boosts LTV, and reduces reliance on constant acquisition.
📌 Key Takeaway
Repeat Purchase Rate is one of the most powerful levers in the customer value stack. The faster you can move customers from one order to two, the healthier your unit economics become.

RPR tells you how many customers come back. But to understand customer behavior more deeply, you need to know how often they buy. That’s where Purchase Frequency comes in — the metric that reveals buying patterns and helps forecast future growth.
