How Many Stamps Should a Loyalty Card Have?

Eight — for most cafes. Daily customers finish in about two weeks. Specialty cafes can use 6. Above 10 and most people give up. Here's how to pick the right number.

Eight. That's the sweet spot for most cafes. A daily customer completes the card in about two weeks — long enough to feel earned, short enough that they don't give up halfway. Specialty cafes with higher-priced items can go with 6. Anything above 10 and most customers never finish.

Does the number of stamps really matter?

More than you'd think. Too few and the reward feels cheap — customers don't value something they barely had to work for. Too many and they lose motivation before they get there. The goal has to feel close enough to chase.

Costa Coffee ran a complex points system for years before switching to a simple "buy 8, get 1 free" stamp card. The result? 16% more transactions. Not because the reward changed — because the path to it became obvious.

What's the right number for my business?

It depends on how often your customers visit and what they spend:

Business typeStampsWhy
Coffee shops / cafes8Daily customers finish in ~2 weeks. The rhythm feels right.
Specialty / premium cafes6Higher price per visit = fewer visits needed to earn the reward.
Restaurants6–8Less frequent visits, so fewer stamps keeps the goal reachable.
Salons / barbershops6–8Visits every 2–6 weeks. More than 8 and they'll never finish.
Juice bars / bakeries8–10Moderate visit frequency. 10 works if the reward is generous.

The pattern is simple: the less often someone visits, the fewer stamps they need. A cafe regular who comes every morning can handle 8. A salon client who visits monthly needs 6, or the card takes half a year.

What's the trick with giving 2 stamps to start?

Give customers 2 stamps on their first visit and they're twice as likely to finish the card. It sounds like you're giving something away — but you're not. They still buy the same number of coffees to earn the reward. They just feel closer to the goal from the start, and that momentum keeps them going.

Think of it like a loading bar. Nobody wants to start at zero. When you see a bar that's already 20% full, you want to finish it. That urge to complete is actually stronger than the desire for the free coffee itself.

You don't need thousands of customers. You need the ones you already have to keep coming back.

Won't fewer stamps cost me more in freebies?

This is the most common worry — and it's backwards. A completed 8-stamp card means a customer visited your cafe 8 times. That's 7 paid purchases for 1 free drink. The visits are worth far more than the freebie.

Now compare that to a 12-stamp card where the customer gives up at stamp 5 and never comes back. You got fewer visits and gave away nothing — but you also lost a customer. The "cheaper" card actually cost you more.

The card that gets completed is always worth more than the card that gets abandoned.

Should I use stamps or points?

For most small businesses, stamps. They're simpler, inflation-proof, and your staff never has to explain anything at the counter. If you're deciding between the two, we break it down in detail in our stamps vs points guide. Short version: start with stamps. You can always add points later.

What about paper stamp cards — does the number matter there too?

The number matters — but the format matters more. Fewer than one in eight paper cards ever gets completed. If you're thinking about switching from paper to digital, we have a step-by-step guide. Short version: run both side by side and customers will naturally move over. A digital card in their phone wallet can't be lost, and they see their progress every time they open it.
