Most Shopify stores can name their conversion rate off the top of their head. Fewer can immediately say what percentage of their customers make a second purchase — even though that number is often a bigger lever on profitability than conversion rate is.
What Repeat Purchase Rate Actually Measures
Simply: of the customers who placed an order in a given period, what percentage placed more than one order? It's a direct measure of whether your product and post-purchase experience are creating loyalty, independent of how many new customers you're bringing in through paid acquisition.
Why It's Easy to Overlook
Repeat purchase rate doesn't show up on most default e-commerce dashboards, and it requires order-history-level analysis rather than a single transaction snapshot — which is exactly why it tends to get less attention than revenue or conversion rate, even though it directly determines how sustainable your growth is.
The Math That Makes This Matter
Acquiring a new customer is consistently more expensive than retaining an existing one. A store with a 25% repeat purchase rate is compounding every acquisition dollar it spends; a store at 8% is essentially starting from zero every month. Small improvements here tend to move overall profitability more than equivalent improvements in conversion rate.
"We were so focused on top-of-funnel conversion rate optimization that we never noticed our repeat purchase rate had been flat for a year. A 4-point improvement there did more for margin than any conversion test we ran."

Levers That Actually Move This Number
Post-purchase email flows, a genuinely good unboxing or first-use experience, loyalty or subscription mechanics, and simply staying visible in a customer's inbox at the right moments — none of this is exotic, but it requires knowing your current rate to know if it's working.
Setting It as a Goal, Not Just a Metric
Repeat purchase rate is one of the metric types worth setting as an explicit, tracked goal — with a target and a timeframe — rather than something you glance at occasionally. SnapDash's goal tracking calculates repeat purchase rate live from real order data, so progress updates automatically as customers place their second order, without a manual recalculation.
