How many stamps for a free coffee?
Short answer: 6 to 10, with 8 being the most common. Here’s why cafes land on that number, what counts as “free”, and how digital and paper loyalty cards differ on the things that matter.

The short version
Most cafe loyalty cards need 8 stamps for a free coffee. The range is 6 (small independents who want fast wins) to 10 (chains with thinner margins). The reward is usually a standard hot drink of your choice, redeemed on your next visit. Digital cards let you stack multiple stamps in one visit; paper cards almost never do.
Why 8 is the most common threshold
When a cafe sets their loyalty threshold, they’re balancing two things: how motivated you feel to come back and how much margin they give up to your reward.
At 6 stamps, a free coffee comes around fast. Customers feel the reward is real, but the cafe is effectively giving away ~14% of their revenue from regulars. At 10 stamps, that drops to 9% — but a lot of customers lose interest before they hit the threshold.
8 lands in the sweet spot. A 5-day-a-week regular hits it in just under two weeks, and the cafe’s giving up roughly 11% of revenue from those customers — a healthy price to pay for someone who comes back every weekday.
What the reward usually looks like
The default is any standard hot drink of your choice — latte, flat white, cappuccino, long black. Some cafes restrict to a regular size; specialty drinks like matcha lattes or single-origin pour-overs sometimes need a top-up.
- Most common: Free standard hot drink, any milk, regular size. No top-up for the obvious stuff (oat, almond, syrup) but specialty extras may cost.
- Generous: Any drink, any size, no exclusions. You see this at independent cafes that want to lean hard into loyalty.
- Restricted: Cheapest drink only, or a fixed dollar value off your next purchase. More common at chains with tighter margins.
When in doubt, the rule is usually written on the card itself when you scan it for the first time.
Digital vs paper: what actually changes
The threshold (6–10 stamps) is the same on both. What’s different is the friction around earning and redeeming.
How to actually earn yours
- 1When you order, look for a QR code at the counter (or just ask if they have a loyalty card). Most cafes do — they're just bad at signage.
- 2Scan with your phone camera. The card opens in your browser — no app to download.
- 3Add at least your name + email on the first scan. Takes 5 seconds. Without it, your stamps live in a cookie on your phone and disappear if you switch devices.
- 4Tap 'Request stamp'. The barista approves it on their end. The stamp lands instantly.
- 5Hit your threshold (8 is the default), tap to redeem next time you order. Hand the barista your phone, free coffee, done.
Common questions
What if the cafe’s loyalty card needs more than 10 stamps?+
Anything above 10 is a stretch. If a cafe sets the bar at 15 or 20, most customers lose interest before they hit it. If you spot one, decide whether the cafe is worth the haul — or if you'd rather take your business to one with a more attainable program.
Can the barista add more than one stamp if I order two coffees?+
On a digital loyalty card, yes — they tap +2 on their dashboard. On a paper card, they almost never will. The whole loyalty model assumes one stamp per visit; doubling up undermines it.
Can I have one loyalty card across multiple cafes?+
No — each cafe runs their own. Your stamps at one cafe don't transfer to another. Some digital loyalty platforms let one customer profile span multiple cafes (each with their own separate card), so you don't have to re-add your details every time.
Do unused stamps eventually expire?+
Digital cards usually don't expire. Some larger chains apply a 12-month rolling expiry on unused stamps; independent cafes rarely do. Paper cards effectively expire whenever you lose the card.
