Shopify Loyalty Programme ROI: Is a Points System Worth Setting Up?

Do Loyalty Programmes Actually Work?

The answer depends entirely on your repeat purchase rate and margin. Starbucks’ loyalty programme drives 57% of their revenue from 16% of customers — it works because they have a natural repeat purchase behaviour (daily coffee) to reinforce. A furniture store with a natural 2-year repurchase cycle gets less value from points because customers won’t collect enough points to care before they buy again anyway. The first question is: do your customers have a reason to buy from you multiple times in the same year?

The True Cost of a Loyalty Programme

A 5%-back points programme sounds affordable. The real cost: if 60% of customers redeem (industry average), and your AOV is £60, you’re effectively giving 5% × 60% = 3% of revenue back to customers. On a 40% gross margin, that’s 7.5% of your gross margin. Add the platform cost (Smile.io: £49–£199/month) and admin time. The programme needs to increase LTV or repeat purchase frequency by more than this cost to justify itself.

When Loyalty Programmes Have Positive ROI

• Repeat purchase businesses: supplements, coffee, cosmetics, pet food, fashion-conscious consumers
• High competition markets where switching costs are low — loyalty creates a structural reason to stay
• Businesses with healthy margins (40%+) that can absorb reward costs
• Stores with strong existing retention rate (25%+) who want to improve it further

Loyalty Programme Structures Compared

• Points system — earn X points per £1 spent, redeem for discounts. Simple, familiar, but can feel transactional. Breakage (unredeemed points) reduces real cost
• Tiered programme — Bronze/Silver/Gold tiers with increasing benefits. Status drives aspiration and higher spend to reach next tier
• Paid membership — Amazon Prime model. Pay £X/year for exclusive benefits (free shipping, early access, member prices). Highest LTV impact of any loyalty model when done well
• Cashback — percentage returned as store credit. Higher redemption rate than points, higher perceived value, simpler to understand

Measuring Loyalty Programme ROI

Compare LTV of loyalty members vs non-members (cohort analysis), repeat purchase rate of enrolled vs non-enrolled customers, average order count per year for members vs non-members, and net revenue impact (incremental revenue from programme members minus reward costs minus platform costs). If programme members’ LTV is more than 20% higher than non-members, the programme is working. If less, redesign or discontinue.
