The Question
How many cups of coffee does a single city cafe sell on a typical weekday? I'll build this bottom-up from the physical thing in front of us: a room with seats, a counter, and a line of people who buy a drink and either sit or leave. The two engines of volume are the people who sit down and turn the seats over, and the people who grab a takeaway cup and never sit at all. I'll size each separately and add them.
Assumptions
- Seats. A mid-sized urban cafe has about 30 seats. Big enough to matter, small enough to be a single shop, not a chain flagship.
- Operating hours. Open roughly 12 hours, say 7am to 7pm.
- Seat turnover. On average a seated customer occupies a seat for 45 minutes, so each seat turns over a little more than once per hour. I'll round to 1.3 turns per hour.
- Drinks per seated visit. Most people buy 1 drink; a few buy two. Call it 1.2 on average.
- Takeaway share. Takeaway is the bigger business. I'll assume takeaway cups outnumber sit-down cups by roughly 1.5 to 1, weighted heavily toward the morning rush.
- Seat utilization. Seats aren't full all day. Average occupancy across the 12 hours is maybe 60% (packed at 8am and 1pm, quiet at 3pm).
The Calculation
Start with seated customers. Thirty seats turning over 1.3 times an hour, if they were full, would be 30 x 1.3 = 39 customers per hour. But seats sit at 60% occupancy on average, so call it 39 x 0.6 = about 23 seated customers per hour.
Over 12 hours that's 23 x 12 = roughly 280 seated customers a day. Each buys 1.2 drinks, giving 280 x 1.2 = about 340 sit-down coffees per day.
Now takeaway. If takeaway runs 1.5x the sit-down cup volume, that's 340 x 1.5 = about 510 takeaway coffees per day. This is the morning-commuter engine plus the lunchtime grab-and-go, and it makes sense that it dominates.
Adding the two streams: 340 + 510 = about 850 cups. I'll round to a clean figure of roughly 800 to 900 coffees a day.
Sanity Check
Let me check this from the revenue side. At an average ticket of about $5 per cup, 850 cups is around $4,250 in coffee revenue a day. A small independent cafe doing $4,000 to $5,000 in daily sales is a healthy, busy shop but not an implausible one, and that figure is before food and pastries, which often match or exceed drink revenue. So the order of magnitude holds.
A second angle: the morning peak. If a third of the day's cups go out in the two-hour 7 to 9am window, that's about 280 cups, or more than 2 per minute. For a shop with two baristas and an espresso machine pulling shots continuously, that's brisk but achievable. If the number had come out at 5,000 cups a day, the implied 10-per-minute peak would have told me I'd made an error somewhere.
What Would Change the Answer
The biggest swing is the takeaway ratio. A cafe next to a subway entrance or office tower might run takeaway at 3x or 4x sit-down volume, easily pushing past 1,500 cups; a sleepy neighborhood cafe where people linger over laptops might do far less takeaway and live closer to 400. Seat count and turnover matter too, but they're bounded by physical space. Location, more than anything, decides whether this cafe is a 400-cup shop or a 1,500-cup one. The 850 figure is the honest middle.
