Repeat Purchase Rate

Most eCommerce teams spend a lot of time optimizing their acquisition funnel: 
Ad → Visit → Add to Cart → Checkout → First Purchase

But the customer journey shouldn't end at the first order. The moment somebody buys for the first time, they enter a second funnel; the retention funnel:
1st Purchase → 2nd Purchase → 3rd Purchase → ... → Loyal Customer

And just like your acquisition funnel, customers drop off at every stage. Your job is to understand: Where do you lose the most customers — and how far do you need to move them before repeat purchasing becomes much more likely?

That's what the Repeat Purchase Rate helps you answer.

Move customers toward loyalty

Imagine 10,000 customers make their first purchase.

Maybe:

4,000 make a second purchase.
2,500 make a third.
1,900 make a fourth.
1,500 make a fifth.

At first glance, you're simply losing customers at every step.

But look at the conversion rate between those steps:

1st → 2nd: 40%
2nd → 3rd: 63%
3rd → 4th: 76%
4th → 5th: 79%

Something interesting happens.

Usually, the hardest purchase to generate is the second one.

But once customers have purchased three or four times, buying from the brand has started to become normal. Their likelihood of purchasing again is significantly higher.

This creates two important concepts for your retention strategy:

Your biggest retention leak

The purchase transition where you lose the largest share — or number — of customers.

Your loyalty threshold

The purchase stage after which Repeat Purchase Rate becomes consistently high and customers are much more likely to continue buying.

Your retention strategy should connect the two:

Move as many valuable customers as possible through the biggest leaks until they reach your loyalty threshold.

The Repeat Purchase Rate report shows you where those opportunities are.

Turn the Retention Funnel into action

The best customers are the ones you already have! After a customer has placed an order, it is your job to inspire them to place the next one. Therefore, it is important to perform your retargeting campaigns at the right time to increase the chance that they will catch your customer's attention.

Step 1: Find the biggest leak

Start with the first stages of your funnel.

For example:

1st → 2nd: 38%
2nd → 3rd: 55%
3rd → 4th: 71%
4th → 5th: 74%

The first-to-second purchase transition is clearly the weakest.

That means a large part of your acquisition investment is currently producing customers who never make it beyond one order. For this brand, improving the second-purchase experience should therefore be one of the highest-priority retention initiatives.

But don't automatically assume Order #2 is your biggest opportunity.

Depending on your business model, you might discover that customers convert well to a second order but struggle to reach the third. Follow the leak in your own funnel.

Step 2: Find your loyalty threshold

Now look further down the funnel.

You're looking for the point where Repeat Purchase Rate starts to stabilize at a significantly higher level.

Using the same example:

1st → 2nd: 38%
2nd → 3rd: 55%
3rd → 4th: 71%
4th → 5th: 74%
5th → 6th: 76%

The significant change happens around the third purchase.

Customers haven't magically become “loyal” because they placed exactly three orders. But their behavior has changed: once they reach this stage, another purchase becomes much more likely.

For this brand, Order #3 is therefore an important loyalty threshold.

This gives the retention team a much clearer objective than simply:

"Increase retention."

The objective becomes:

Get more first-time customers to their third purchase.

Now you can build a strategy around it.

Step 3: Understand what gets customers through each stage

Not every step of the retention funnel should be treated the same.

A customer approaching their second purchase may still be discovering your assortment.

A customer approaching their third purchase may already have a favorite category but need another reason to return.

A five-time buyer probably doesn't need the same incentive as a one-time buyer.

Apply customer and product segments to your Repeat Purchase Rate to investigate what separates customers who progress from those who don't.

For example, compare:

• First purchase product or category
• Subscribers vs. non-subscribers
• High- vs. low-value customers
• Acquisition channels
• Markets or stores

You might discover that customers acquired through one channel have a strong first purchase but rarely make a second.

Or that customers entering through one particular product have a much higher likelihood of reaching your loyalty threshold.

Those aren't just retention insights.

They can influence your acquisition, merchandising, CRM, and promotion strategy.

Step 4: Know when to intervene

Once you know which purchase you need to drive, determine when the customer should reasonably make it.

Use the Time Between Purchases report.

Suppose the median time between Order #1 and Order #2 is 60 days.

A one-time buyer whose order was 20 days ago isn't necessarily a retention problem. They're still behaving normally.

A one-time buyer whose last purchase was 90 days ago is different.

They have moved beyond the typical repurchase window and may need a reason to come back.

This creates a simple retention framework:

Funnel Stage + Expected Timing = Action

Ask:

Where is the customer in the retention funnel?
Are they already overdue for the next step?

Only then decide how to engage them.

Step 5: Build audiences around the next purchase

Now translate your strategy into dynamic customer segments.

If Order #3 is your loyalty threshold, you might create:

Overdue one-time buyers
Goal: Drive Order #2

Overdue two-time buyers
Goal: Drive Order #3

These are much more actionable audiences than a broad segment such as “existing customers.”

And their treatment doesn't need to be identical.

For example:

Order #1 → #2

Help customers discover the next relevant product, replenish what they purchased, or experience another part of the assortment.

Order #2 → #3

Strengthen the relationship through cross-selling, loyalty benefits, or a more personalized Next Best Offer.

Beyond the loyalty threshold

Protect the relationship rather than unnecessarily discounting it. Focus on relevance, newness, exclusivity, and convenience.

The goal is always the same:

Give customers the right reason to take the next step through the retention funnel.

Step 6: Activate your strategy

Connect your marketing platform to RetentionX and push your segments as dynamic audiences.

Customers automatically enter when they meet your conditions and leave once they move to the next stage.

You can use these audiences across:

• Email and SMS
• Replenishment flows
• Win-back campaigns
• Next Best Offer campaigns
• Paid audiences
• Targeted promotions

This turns the Retention Funnel from an analysis into an always-on lifecycle strategy.

Measure whether customers are moving

After implementing your initiatives, come back to the Repeat Purchase Rate.

Don't ask only:

“Did the campaign generate revenue?”

Ask:

“Did more customers move to the next stage of our retention funnel?”

If you focused on first-time buyers, your 1st → 2nd Repeat Purchase Rate should improve.

If Order #3 is your loyalty threshold, monitor whether a greater share of customers is making it there.

You can complement this with Customer Cohorts by Retention Rate to understand whether newer customer cohorts are developing better than previous ones.

Ultimately, the goal isn't to get every customer to purchase forever.

It's to systematically identify:

Where customers drop → which customers are worth moving forward → when to engage them → what will get them to the next purchase.

That's how you turn retention from a collection of campaigns into a strategy.
