Part of our complete guide: how to find vending machine locations.
- Standard combo machine: about 75–100 daily captive people to work, 150-plus to be comfortable.
- Apartments need far more than offices — roughly 100 units as a floor, 150–250 to be comfortable, because residents have kitchens.
- Capture rate, not headcount, is the real variable: 8–12% in a captive workplace, 4–8% in a typical office, 1–3% in residential and pass-through sites.
- The target is 10–12 vends a day — roughly $500 gross a month, $150–250 net.
- Below the floor you still have three options: a cheaper machine, a site inside an existing cluster, or pairing it with a neighbour.
Every location guide tells you to look for foot traffic. Almost none of them tell you how much. This page gives the number: the minimum population a site needs before a vending machine is worth placing, why the answer is completely different for an apartment building than for a warehouse with the same headcount, and what to do about the sites that fall just underneath it.
The formula everything else is built on
Estimated monthly gross equals daily captive population × daily capture rate × average ticket × operating days. Four inputs, and only one of them is the number people ask about.
- Daily captive population. Not the building capacity and not the annual visitor count. The number of people present on a typical day who cannot conveniently leave to buy something else.
- Daily capture rate. The share of that population who buy something from the machine on a given day. This is the variable that actually decides outcomes, and it ranges from about 1 per cent to about 15 per cent.
- Average ticket. Roughly $2.00 to $2.25 for a modern snack and drink machine at current pricing. Higher with premium energy drinks, lower on a candy-led planogram.
- Operating days. About 22 for a weekday-only workplace, 30 for residential and round-the-clock sites. This alone makes a seven-day site worth roughly a third more than a five-day site at equal population.
Run it on a 100-person office with an 8 per cent capture: 100 × 0.08 × $2.10 × 22 = about $370 a month gross. After cost of goods at 45 to 55 per cent and a typical commission, that is roughly $130 to $170 net. Real but thin. Now the same 100 people in a warehouse with no shop nearby at a 12 per cent capture: about $554 gross, and comfortably over $200 net. Identical headcount, very different business — which is the entire point.
The floor, stated plainly
A machine needs roughly 10 to 12 vends a day to gross about $500 a month, which nets $150 to $250 once cost of goods and commission are paid. That is the level at which a placement justifies the drive, the capital and the attention. Working back through the formula, that means:
| Site character | Typical capture | People needed for the floor |
|---|---|---|
| Captive, no alternatives, shift-based | 8–12% | 75–110 |
| Typical office with a cafe nearby | 4–8% | 110–220 |
| Residential building | 1–3% | 250–500 residents |
| Pass-through lobby or retail frontage | 0.5–2% | 400–1,500 daily passers |
So the honest single-sentence answer is 75 to 100 daily captive people, with the strong caveat that captive is doing most of the work in that sentence. Below about 50 people, a full-size machine at an isolated site is very unlikely to earn its stop.
Picture the machines paying you while you sleep

Three things move capture rate, and each of them can swing a site by a factor of three or more.
- Dwell time. Capture roughly doubles once people are stuck somewhere for 45 minutes or more with nothing to do. This is why a car dealership service department with only 30 waiting customers a day can outperform a 60-person office — those 30 people are there for two hours with nowhere to go.
- Alternatives. If there is a shop, a canteen or a coffee place within a five-minute walk, capture falls off a cliff. The single best question to ask on a site visit is not how many people work here, it is what people currently do when they want a drink.
- Shift structure. A 24/7 operation multiplies your effective population because each shift is a separate audience, and the night shift almost always has zero alternatives. A 60-per-shift facility running three shifts behaves like a 180-person site. Sites like this are worth going out of your way for — see 24/7 warehouse and data centre vending.
Headcount is the input everyone can get on a phone call, which is why it dominates the conversation. The other three are what actually decide whether the machine works, and they are the reason a scoring system beats a threshold. The ten-factor version is the location scoring checklist.
Thresholds by venue type
Working floors and comfortable levels for a standard combo machine. Comfortable means the placement is clearly worth keeping rather than merely defensible.
| Venue | Working floor | Comfortable | What actually decides it |
|---|---|---|---|
| Manufacturing or warehouse | 40 per shift | 75+ per shift | Shift count multiplies everything; short breaks make leaving impossible |
| Office or professional | 50–60 staff | 100–150 | Whether there is a canteen or a cafe within five minutes |
| Independent gym | 250 members | 500+ | Drinks-led and spiky; post-workout capture is unusually high |
| Apartment building | 100 units | 150–250 units | Kitchens suppress capture; amenity traffic is the only real lever |
| Hotel | 60 rooms | 100+ rooms | Late-night demand with zero alternatives carries the machine |
| Car dealership service | 25 daily service customers | 40+ | One to three hours of forced waiting, not headcount |
| Laundromat | 40 daily visits | 80+ | Long dwell, fully captive, seven days a week |
| Hospital or 24/7 care | 100 daily staff and visitors | 250+ | Night shift and visitor stress both push capture up |
| School | 150 students | 300+ | Access windows and nutrition policy cap it more than population does |
| Self-storage or trade counter | Fails on headcount | — | Only works as drinks-led cluster filler, especially in hot climates |
The revenue each of these actually produces once placed is in vending machine profit by location type, and the ranked view of which venue types to chase first is the best vending machine locations for 2026.
The apartment question, answered directly
This comes up more than any other version of the threshold question, usually in the form of a specific building: is a 57-unit apartment building big enough for a vending machine?
Honestly, on population alone, no. Fifty-seven units is roughly 120 residents. At a residential capture rate of 1.5 per cent that is about 1.8 vends a day, or roughly $115 a month gross — well under the floor, and that is before commission. Residents have kitchens, they buy groceries, and the machine is competing with a fridge 40 feet away. Apartment capture is structurally low, and no amount of merchandising fixes a structural problem.
Three things can rescue a building that size, and they are all about concentrating traffic rather than adding people:
- Amenity traffic. A busy on-site gym, pool or package room changes the maths, because it puts residents in one spot in a state where they want a cold drink. A machine beside a well-used gym in a 57-unit building can work where a machine in the lobby of the same building will not.
- Cluster economics. If the building is five minutes from three other stops, the marginal cost of the visit is small and a thin machine is still worth carrying. Isolated, it is not.
- A cheaper machine. A drinks-only unit or a smaller-footprint machine drops the revenue bar to something 120 residents can clear.
What does not work is a smart cooler in a 57-unit building. At $5,000 to $10,000 and up, that class of machine needs a much larger population to justify the capital — the comparison is in smart cooler vs micro market. The residential playbook overall, including how to pitch buildings that do clear the bar, is in apartment and office vending as a modern amenity and the apartment vending pitch template.
What to do when a site is under the floor
Under the threshold is not automatically a no. It is a no for that machine, at that cost, as an isolated stop. Four responses, roughly in order of how often they are correct:
The capacity cost referenced in the first and last of those is real and quantified in how many vending machines one person can service — the reason to be disciplined about the floor is that every stop you add is a permanent claim on your week.
Verify with data, not with the estimate
Everything above is a screening tool, not a forecast. The estimate exists to tell you whether to pitch, not whether to keep. Once a machine is in, the only number that matters is what it actually sells, and you need about 90 days before the data means anything — that method is the 90-day vending location test. Cashless readers make this straightforward because every sale is timestamped, so you can see not just how much the site sells but when, which tells you whether you sized the population correctly or misjudged the shift pattern. How to read those reports is in reading vending machine sales reports.
If a placed machine is coming in well under what the population predicted, the causes are usually merchandising, pricing or placement within the building rather than the population estimate itself — the diagnostic order is in why your vending machine is not making money.

Frequently Asked Questions
How many people does a location need for a vending machine?
For a standard snack and drink combo, roughly 75 to 100 daily captive people is the working floor and 150-plus is comfortable. Below about 50 the machine will not clear enough to justify the service stop unless something else compensates - very long dwell time, no food or drink alternative nearby, or round-the-clock shifts. Captive is the load-bearing word: people who cannot easily leave count, people passing through mostly do not.
How many apartment units do you need for a vending machine?
Around 100 units as a floor and 150 to 250 to be comfortable, which is considerably higher than the equivalent office headcount. The reason is that residents have kitchens, so the daily capture rate in a residential building runs closer to 1 to 3 per cent rather than the 8 to 12 per cent you see in a captive workplace. A 57-unit building is genuinely marginal for a full-size machine unless it has amenity traffic - a busy gym, pool or package room - concentrating footfall in one spot.
What is the minimum foot traffic for a vending machine to be profitable?
Work in vends per day rather than people. A machine needs roughly 10 to 12 vends a day to gross about $500 a month and net $150 to $250 after cost of goods and commission. Whether your site produces that is a function of population multiplied by capture rate, and capture rate swings from about 1 per cent in a pass-through lobby to 12 per cent or more in a warehouse night shift with nothing else available.
Can a vending machine work in a small office?
Under about 40 staff a full-size combo rarely earns its stop, though there are two ways it can work anyway. Put a machine at a small site that sits inside a cluster you already service, so the marginal time cost is close to zero. Or place something much cheaper - a bulk candy machine or a small drinks-only unit - where the revenue bar is far lower. What does not work is a full-size machine at an isolated 25-person office 30 minutes from your other stops.
Why do two locations with the same headcount earn different amounts?
Capture rate, which is driven by dwell time, alternatives and shift structure rather than by headcount. A hundred warehouse workers on a 20-minute break with no shop nearby will out-earn a hundred office workers next to a cafe by a factor of three or four. If people can easily buy something better within a five-minute walk, headcount stops predicting revenue almost entirely.
Does a 24/7 site change the numbers?
Substantially, and it is the most underrated factor in placement. Round-the-clock operations multiply the effective population because each shift is a separate audience, and the night shift in particular has almost no alternatives, which pushes capture rates to the top of the range. A 60-person-per-shift facility running three shifts behaves much more like a 180-person site than a 60-person one.
What should I do if a location is below the threshold?
Three real options before you walk away. Place a cheaper machine so the revenue bar drops to match the site. Take it only if it sits inside an existing cluster, where an extra ten minutes costs you nothing. Or combine it with a neighbouring small site so one stop serves two machines. Walking away is also a legitimate answer - a marginal machine consumes route capacity that a better site could have used.
How do I estimate revenue before placing a machine?
Multiply the daily captive population by a capture rate, by an average ticket of about $2.00 to $2.25, by operating days per month. Use 8 to 12 per cent capture for captive workplaces with no alternatives, 4 to 8 per cent for typical offices, and 1 to 3 per cent for residential and pass-through sites. Then halve your confidence in the result and verify it with 90 days of actual sales data before you draw any conclusions.
