vending machine ROI calculator
The only vending ROI formula that matters
Every vending machine business plan, no matter how elaborate, collapses down to one line: people on site multiplied by the share of them who buy, multiplied by what they spend, multiplied by your gross margin. That is your daily gross profit. Multiply by trading days for the week, by roughly twenty for the month, and you have the number that tells you whether a location is worth buying.
Operators get into trouble when they skip a variable. Revenue-only thinking is the classic mistake — a busy machine turning over $500 a week at a thin margin on branded drinks can make less money than a quieter machine running a sensible confectionery and snack mix. Headcount-only thinking is the other trap: a 300-person site where nobody buys because there is a subsidised canteen forty metres away is worth less than a 70-person workshop with no food within a ten-minute drive.
The calculator on this page forces all four variables into the open. Set the staff and visitor numbers from the verified site brief, set a conservative buyer rate, set the average spend you actually expect from your planogram, and set the gross margin you achieve with your current supplier. What comes out is a defensible weekly and monthly figure you can take to a lender, a partner, or your own decision to click buy.
- Daily gross profit = people × buyer rate × spend × margin
- Weekly = daily × trading days on site
- Payback = site cost ÷ weekly gross profit
- Contribution = gross profit − route cost − repayment
Staff versus foot traffic — why VendSites prices them differently
Not everyone who walks past a machine is a potential buyer in the same way. Staff are the reliable base: they are on site five days a week, they learn the machine, they form habits, and they come back for the same product at the same time every day. Visitors and general foot traffic are a genuine revenue layer, but the conversion is lower and less predictable, which is why VendSites values staff headcount at $5 per head and daily visitors at $1 per head when a location is priced.
That pricing logic should flow straight into how you model. A 120-staff distribution centre with almost no visitors behaves very differently from a 25-staff gym with 400 people a day through the door. The gym has more bodies but a narrower buying window and a different product mix — cold drinks, protein, isotonic lines — while the distribution centre supports a full snack and drink combo with a predictable morning and afternoon peak.
The calculator adds staff and visitors together into a single pool of potential buyers, but you should sanity-check the blend. If a site is mostly visitors, drop your buyer rate a few points and lift the average spend if the mix skews to drinks. If a site is almost all staff, you can be a little braver on buyer rate but should assume repeat purchase of lower-priced lines.
Costs the headline number does not include
Gross profit is not take-home. Once the machine is trading you carry a route cost: fuel and vehicle time to service the site, the cashless card reader's transaction percentage, a telemetry SIM if the machine reports remotely, public and product liability insurance, and any commission you have agreed with the site. On a metropolitan route with tight drops, most operators budget $20–$45 a week per machine all-in, plus card fees of roughly 1.5–3% of cashless turnover.
Machine finance is the other line. An indicative combo machine plus cashless reader, delivered and installed, sits around $8,500, which over a three-year equipment finance term is a weekly direct debit in the low-to-mid sixties before fees. The calculator surfaces that repayment and expresses it as a share of estimated weekly takings, because that ratio is what a lender looks at and it is also the fastest way to spot a site that will technically trade but never actually pay you.
There is also the cost of getting it wrong. Chasing a site through cold calls, reception gatekeepers and a manager who has moved on burns weeks of unpaid time. That is the reason the location fee exists at all: you are buying a verified, contactable, ready-to-install site instead of buying yourself a prospecting project.
- Route servicing: $20–$45 per machine per week
- Cashless fees: ~1.5–3% of card turnover
- Insurance: $20m public & product liability
- Telemetry SIM and remote monitoring subscription
Using the calculator before you buy a location
Every listing on the VendSites marketplace carries the verified staff headcount and daily visitor figure supplied by the workplace contact, plus the site type and the machines requested. Open a listing, note those two numbers, and drop them into this calculator with your own buyer rate, spend and margin. If the weekly gross profit comfortably clears your route cost and machine repayment with room to spare, the site is worth buying. If it is marginal, either negotiate a cheaper machine, run a smaller footprint unit, or wait for the next release.
Pro members see new locations for the first twenty-four hours, free members for the next twenty-four, and the wider public after that. Running the numbers quickly matters, which is why this calculator exists as a standalone page you can keep open in a second tab while the release board counts down. The maths takes ten seconds once you know your own margin.
Once you have bought, the same model becomes your benchmark. Compare the machine's actual cashless data after four weeks against what you modelled here. If the buyer rate is higher than you assumed, that site probably supports a second machine or an upgraded planogram. If it is lower, adjust the product mix before you write the site off — most underperforming sites are planogram problems, not people problems.
From ROI model to installed machine
A good number on this page is the start of a sequence, not the end. Once a site stacks up, you need the hardware, the payment device, the funding and the cover. Machines for sale — new and used — sit in our machines hub, with a comparison table by site type and landed cost. Cashless card readers from Nayax, Cantaloupe, Vendcell and similar are compared side by side with setup time and telemetry depth, which matters because that telemetry is what proves your ROI later.
Vending finance is covered separately, including chattel mortgage versus rental, deposits, low-doc options for newer ABNs and what a lender wants to see. Public and product liability cover at $20 million is effectively mandatory for workplace sites and is the single cheapest piece of risk management in the business — and the card reader's timestamped transaction record is often what resolves a claim in your favour.
If you are still building the fundamentals, the Operator Academy has the road-level material: machine selection horses-for-courses, DIY fault finding, seasonal stocking and route planning. The calculator tells you whether a site pays. The Academy tells you how to make sure it does.
Questions operators ask
- How much does a vending machine make per week in Australia?
- A single machine on a decent workplace site with 60–100 staff usually turns over $150–$450 a week, which is roughly $60–$220 a week in gross profit at a 40–50% margin. High-traffic sites — hospitals, gyms, apartment lobbies, transport depots and 24/7 manufacturing plants — go well past that because the same machine sells around the clock instead of only during office hours. The three levers that actually move the number are the buyer rate, the average spend and the product margin, which is exactly what this calculator lets you change.
- What buyer rate should I assume for a workplace vending site?
- For a straight snack and drink combo in an office, 10–20% of the people on site buying on any given day is a realistic planning figure. Sites with limited nearby food options, shift work, or no on-site cafeteria run higher — 25–35% is common in warehouses, factories and hospitals. Be conservative first: model at 12–15%, confirm the site still works, and treat anything above that as upside rather than the basis of your purchase decision.
- How do I calculate the payback period on a vending site location?
- Divide the total cost of getting trading — the site location fee plus any machine deposit and delivery — by the weekly gross profit the site produces. If a location costs $500 and the machine clears $120 a week in gross profit, the location itself pays back in about four to five weeks and everything after that funds the machine and your route costs. Anything under about twelve weeks on the location fee alone is a strong site by Australian standards.
- Should I use gross profit or revenue when assessing a site?
- Always gross profit. Revenue flatters a site because cost of goods on confectionery, drinks and snacks is typically 45–65% of the retail price. Work in gross profit, then subtract your route costs — fuel, time, card reader fees, telemetry SIM, insurance and machine repayment — to see the real weekly contribution. A site with $400 of weekly revenue and a 30% margin makes less money than a site with $260 of revenue at a 55% margin.
- Does the calculator account for equipment finance repayments?
- Yes. It shows an indicative weekly direct debit for a combo machine plus cashless card reader financed over three years and tells you what share of the site's estimated takings that repayment represents. Most equipment lenders want repayments comfortably inside site revenue, so if the repayment is eating more than about a third of takings the site is better paired with a second location or a cheaper machine. It is an affordability guide, not a credit offer.
- How accurate are these vending ROI numbers?
- They are as accurate as your inputs. The maths is simple and honest: people on site × buyer rate × average spend × gross margin. What makes the result reliable is the input quality, and that is exactly why every VendSites location is verified with the workplace contact before it is listed — the staff headcount and visitor numbers you plug in come from the site itself, not from a guess or a stale database.
