Café Marketing Metrics: 8 Numbers Every Week
Every week without these eight numbers, you're flying your café blind – and you won't notice regulars are gone until it's too late.
Eight numbers, ten minutes per week, and you know if your café is really growing or just making sales. Every metric comes with a formula, example calculation, and a hint on what to do if the number moves the wrong way.
Why Revenue Alone Isn't Enough
Weekly revenue is the number every owner knows. But it doesn't tell you where the revenue comes from.
€6,000 from 200 regulars is stable business. €6,000 from 900 walk-ins who never come back is a business that starts from zero every week. The following eight metrics separate exactly that.
For the examples, we'll use a café with around €6,300 weekly revenue and a digital stamp card. The card delivers customer-related numbers automatically.
The 8 Metrics at a Glance
| No. | Metric | Formula | Example Value |
|---|---|---|---|
| 1 | Active Customers | Customers with at least one visit in 30 days | 240 |
| 2 | Repeat Rate | Repeat customers ÷ active customers × 100 | 68 percent |
| 3 | New Customers per Week | First visits in the week | 22 |
| 4 | Average Transaction Value | Revenue ÷ number of transactions | €4.50 |
| 5 | Visit Frequency | Visits ÷ active customers (30 days) | 3.8 |
| 6 | Redemption Rate | Redeemed cards ÷ full cards × 100 | 82 percent |
| 7 | Push Response Rate | Visits within 48h after message ÷ recipients × 100 | 9 percent |
| 8 | Weakest Day of Week | Revenue of weakest day ÷ average daily revenue × 100 | 61 percent |
1. Active Customers
Active customers are all people who visited you at least once in the last 30 days. That's your actual customer base. Not the total number of cards ever issued.
Example: The café has issued 410 stamp cards. Only 240 of them were scanned in the last 30 days. Those 240 are the relevant number.
If it rises week after week, your café is growing. If it stays the same while card numbers grow, you're gaining customers only to lose them again.
2. Repeat Rate
The repeat rate shows what share of your active customers came back more than once.
Repeat Rate = Customers with 2+ visits ÷ active customers × 100
Example: Of 240 active customers, 163 came at least twice. 163 ÷ 240 × 100 = 68 percent.
The remaining 32 percent are first-time visitors whose second visit is still to come. That second visit is the most important moment in a café. Those who come twice usually come a third time too. The long-term view of this number is covered in customer retention rate.
3. New Customers per Week
Count how many people created a card for the first time in the week. This number shows if your shop is visible from outside: walk-in traffic, Google listing, word of mouth.
Example: 22 new cards in the week. If 15 customers leave at the same time, the shop grows by 7 customers net.
If new customers drop over several weeks, it's time to boost visibility. Like a better Google Maps listing.
4. Average Transaction Value
Average Transaction Value = Revenue ÷ number of transactions
Example: €6,300 ÷ 1,400 transactions = €4.50.
Average transaction value is the lever that brings revenue without a single extra guest. If it rises by 50 cents, that's €700 more per week at 1,400 transactions. Regulars help with this. They're more likely to add a pastry to their coffee when they know the place.
5. Visit Frequency
Visit Frequency = Visits in 30 days ÷ active customers
Example: 912 scans ÷ 240 active customers = 3.8 visits per customer per month.
This number is the core of every stamp card. A guest who goes from 3.8 to 4.5 visits brings about €3 more per month at €4.50 per transaction. With 240 customers, that's over €700 monthly – without a single new customer.
6. Redemption Rate
Redemption Rate = redeemed rewards ÷ full cards × 100
Example: 50 cards were full in the month, 41 rewards were redeemed. 41 ÷ 50 × 100 = 82 percent.
A high redemption rate is good. It means the reward brings the customer back. If the rate is below 50 percent, the reward is too unattractive or the customer doesn't know the card is full. A Wallet card shows them directly on their phone.
7. Push Response Rate
Push Response Rate = Visits within 48 hours after message ÷ recipients × 100
Example: 200 customers got a message "Today: second coffee half price" on their lock screen. 18 came within two days. 18 ÷ 200 × 100 = 9 percent.
Compare this rate between your messages. Then you learn which offers really move your customers. Whether those 18 would have come anyway is clarified by a control group.
8. Weakest Day of Week
Share = Revenue of weakest day ÷ average daily revenue × 100
Example: Tuesday brings €550, average daily revenue is €900. 550 ÷ 900 × 100 = 61 percent.
Tuesday runs at only about 60 percent of normal power. But rent and staff cost the same on Tuesday as on Saturday. A weak-day booster that sends a small offer to your regulars on exactly that day is the cheapest way to fill this gap.
Take the Self-Test: Do You Know These Numbers for Your Café?
- How many active customers did I have in the last 30 days?
- How many of them came more than once?
- How many new customers came last week?
- What was my average transaction value last week?
- How often does a regular come per month?
- Which day of the week runs weakest?
If you can't answer three or more questions off the top of your head, you're flying your café blind. The good news: you get all eight numbers in ten minutes per week.
Here's What Your Weekly Routine Looks Like
Monday morning, 10 minutes: Write all eight numbers in one line, next to last week's numbers.
Improve one number per week: Not everything at once. This week average transaction value, next week new customers.
Trend over single value: Only after four weeks do you decide if something really works. A rainy week skews every single number.
Share numbers with your team: Whoever stands at the counter moves average transaction value and redemption rate more than any advertising.

What Happens If You Don't Change Anything
Without these eight numbers, you won't notice when regulars disappear. You only see revenue fluctuating. But you don't know if that was the weather or ten regulars who haven't been in for three weeks.
Every week without metrics is a week you don't see problems until it's too late. Every week with metrics is a week you steer instead of hope.
Conclusion
Eight metrics, once per week, and you see your café as it really is. Who comes, who stays, who leaves, and what that means in euros. Revenue and transaction count come from your register. Customer-related numbers come from a digital stamp card automatically in the dashboard. With stampa you start free – up to 100 active customers, no credit card, set up in five minutes.
