Vending machine profit calculator searches reveal a universal truth about the vending industry: everyone wants to know the numbers before they invest. The problem is that most numbers published online are wildly optimistic, US-focused, or deliberately vague to sell you a course or a franchise. This vending machine profit calculator guide gives you realistic UK figures — the actual revenue ranges, the real costs, the margins you can expect, and the net profit that lands in your pocket after everything is paid.

No hype, no best-case fantasies — just the arithmetic that determines whether vending works for you.

The figures in this vending machine profit calculator are based on typical UK operator experiences and are consistent with industry benchmarks from the Automatic Vending Association (AVA). Your actual results will vary based on location, product mix, machine type, and operational efficiency — but these ranges give you a reliable framework for planning.

Vending machine profit calculator — the formula

Every vending machine profit calculator comes down to the same simple equation:

Net Profit = Gross Revenue – Product Costs – Commission – Electricity – Fuel/Travel – Card Processing Fees – Maintenance

That is it. There is no magic. The skill is in maximising the first number and minimising everything after it.

Let us break down each component with realistic UK figures.

Vending machine profit calculator — revenue by location type

Revenue is driven by one thing: how many people walk past your machine and how often they buy. Location is the single biggest variable in any vending machine profit calculator.

Location type	Foot traffic	Monthly revenue	Avg. transactions/day
Small office (20–50 staff)	Low	£120–£250	4–8
Medium office (50–150 staff)	Medium	£250–£500	8–16
Factory/warehouse (100–300 staff)	Medium-High	£400–£700	13–23
Gym/leisure centre	Medium	£300–£600	10–20
University/college	High (term time)	£500–£900	16–30
Hospital/NHS site	High	£600–£1,000	20–33
Transport hub/service station	Very high	£800–£1,500+	26–50+

Vending machine profit calculator — the costs

1. Product costs (your biggest ongoing expense)

Product cost — what you pay for the items you stock — is the largest variable cost in any vending machine profit calculator. The goal is to maintain a product cost ratio of 45–55% of revenue, leaving a gross margin of 45–55%.

Product type	Wholesale cost	Vend price	Gross margin
Crisps (standard multipack)	£0.25–£0.35	£0.80–£1.00	60–70%
Chocolate bar (standard)	£0.30–£0.45	£0.90–£1.20	55–65%
Bottled water (500ml)	£0.15–£0.25	£0.80–£1.00	70–80%
Fizzy drink (can)	£0.25–£0.40	£0.90–£1.20	60–70%
Energy drink (can)	£0.50–£0.70	£1.50–£2.00	55–65%
Protein bar (premium)	£0.80–£1.20	£2.00–£2.50	50–55%

Buying in bulk from cash-and-carry wholesalers (Booker, Bestway, Costco) keeps your product costs at the lower end of these ranges. Buying from supermarkets at retail prices destroys your margins — this is one of the most common beginner mistakes that any vending machine profit calculator would expose instantly.

2. Commission or rent (location dependent)

Arrangement	Typical cost	When it applies
Zero commission	£0	Small offices, community centres, low-traffic sites
Low commission	5–10% of revenue	Medium offices, small factories
Standard commission	10–15% of revenue	Larger workplaces, gyms, public sites
Premium commission	15–20% of revenue	High-traffic sites, hospitals, transport hubs
Fixed rent	£30–£100/month	Some commercial and retail locations

3. Electricity (usually free to you)

In the vast majority of placement agreements, the site owner covers electricity. If you do pay, budget roughly £30–£100 a month for a chilled machine, depending on its age and your tariff, and less for an unchilled snack machine. Our guide to vending machine electricity costs breaks this down.

Most vending machine profit calculator models exclude electricity because it is rarely your cost — but confirm this in your placement agreement.

4. Fuel and travel

Budget £15–£40/month per machine depending on distance from your base and how many machines are on each route. Tight geographic clustering reduces this significantly — five machines within a 10-mile radius costs far less per machine than five machines spread across 50 miles. This is one of the hidden costs that a simple vending machine profit calculator often misses.

5. Card processing fees

Contactless payment providers charge 1.5–3.5% per transaction plus a small fixed fee. With Irelley, card payment with telemetry costs £10 a month plus 2% per transaction. On a machine generating £400/month, card processing fees run approximately £8–£16/month.

This cost is offset many times over by the 20–30% increase in average transaction value that cashless payments deliver.

6. Maintenance and repairs

Budget £10–£20/month per machine for occasional repairs — jammed motors, faulty coin mechanisms, worn spirals. New machines need less maintenance; older machines need more. This is an average across the year — some months nothing breaks, other months you replace a motor.

Any vending machine profit calculator should include a maintenance reserve.

Vending machine profit calculator — work out your own numbers

Use this simple worksheet to run your own vending machine profit calculator for any site. Fill in your best estimate for each line, using the lower end of the ranges in this guide.

Line	How to estimate it
1. Daily sales	People passing each day × share who buy (often 5–15%)
2. Average sale	Typical price of your products, e.g. £1.20
3. Monthly revenue	Line 1 × line 2 × 30
4. Stock cost	Around 45–55% of line 3
5. Commission	0–20% of line 3, as agreed with the site
6. Card fees	£10 a month + 2% of card sales with Irelley
7. Fuel, repairs, electricity	Your own estimate per machine
8. Net profit	Line 3 minus lines 4–7

Run the vending machine profit calculator three times: a low, a middle and a high case. Plan your budget around the low case, and treat anything above it as a bonus.

Vending machine profit calculator by machine type

Different machines produce different numbers. Here is how the vending machine profit calculator changes by type.

Snack machines

Snack machines have low running costs, especially unchilled models, and long shelf lives keep waste low. Margins are steady, making them a reliable first machine. Our snack machine buying guide explains what to look for.

Cold drinks machines

Drinks carry some of the best margins, particularly water and soft drinks. Refrigeration adds to running costs, and sales rise in summer and fall in winter.

Combo machines

Combos sell snacks and drinks from one unit, so they suit sites with room for only one machine. Revenue per square metre is high.

Coffee machines

Hot drinks have strong margins per cup but need ingredients, cups, water and more frequent cleaning. They work best at sites with steady all-day demand.

Fresh food machines

Chilled meals sell at higher prices, but waste from unsold stock can eat into profit. Only add them where footfall is high enough to sell stock before its use-by date. Our guide to food vending machines covers the details.

Net profit	£252/month

Vending machine profit calculator — scaling the numbers

A single machine generating £70–£250/month in net profit is not a life-changing income. But vending is a numbers game — the profit comes from scale. Here is what the vending machine profit calculator looks like across a growing route:

Machines	Avg. net profit/machine	Monthly total	Annual total	Weekly hours
1	£150	£150	£1,800	2
3	£150	£450	£5,400	5
5	£160	£800	£9,600	7
10	£170	£1,700	£20,400	12
15	£180	£2,700	£32,400	16
20	£190	£3,800	£45,600	20

Notice that the average net profit per machine increases as you scale. That is because fixed costs like fuel are shared across more machines on each route, purchasing power improves with volume, and operational efficiency increases with experience. The vending machine profit calculator gets more favourable the more machines you operate.

Vending machine profit calculator — buying on a payment plan

You don’t have to pay for a machine upfront. Irelley payment plans start with a 25% deposit, then spread the balance over up to 12 months at 0%, with no credit check.

Take a £995 slim combo machine as an example. A 25% deposit is about £249, leaving around £746 to spread over 12 months, or roughly £62 a month.

If that machine makes £150 a month net profit, it covers the monthly payment with money to spare. Add the payment to your vending machine profit calculator as a cost for the first year, then watch your profit jump once it’s paid off. See our vending machine payment plans for details.

Start-ups can ask about a reduced 20% deposit. Delivery and installation are free anywhere in the UK, so there is no extra upfront cost to add to your figures beyond the deposit, first stock and insurance.

Vending machine profit calculator — what if sales are lower?

Every site has quiet weeks. Testing a lower-sales scenario shows how much buffer you have.

If the factory in Scenario B took £400 instead of £550, stock would fall to about £192 and commission to £40. After fuel, card fees and maintenance, net profit would still be around £125 a month.

If a site only makes money in your best-case vending machine profit calculator, it is probably the wrong site. Look for locations that still work at the low end.

Vending machine profit calculator — don’t forget VAT

Most small operators stay below the £90,000 VAT registration threshold. If you register, a sixth of every standard-rated sale goes to HMRC, which changes your numbers significantly.

Build VAT into your vending machine profit calculator as soon as your route starts growing. Our guide to vending machine VAT explains how it works.

Vending machine profit calculator — payback period

The payback period is how long it takes for a machine’s cumulative net profit to cover its purchase price. This is the number that tells you how quickly your investment starts generating pure profit.

Machine cost	Avg. monthly net profit	Payback period
£795 (snack machine)	£100	8 months
£995 (slim combo)	£150	7 months
£1,500 (mid-range combo)	£150	10 months
£2,500 (large touchscreen combo)	£250	10 months

Vending machine profit calculator — assumptions to check

A vending machine profit calculator is only as good as the numbers you put into it. Before you rely on the result, check these common assumptions.

• Footfall: ask the site how many people are on site each day, and on which days. A building with 200 staff may only have 120 in on a Friday.
• Competition: a café, canteen or shop nearby will cut your sales.
• Opening hours: long hours and shift work push sales up.
• Seasonality: drinks sell more in summer, and schools and universities go quiet in holidays.
• Price levels: check what nearby shops charge, so your prices feel fair.
• Who pays electricity: confirm it in writing, because it changes your costs.

Revisit your vending machine profit calculator after the first three months using real sales data. It will be far more accurate than any estimate made before the machine went in.

Vending machine profit calculator — what kills your margins

• Buying stock at retail prices: Buying crisps from Tesco instead of Booker cuts your gross margin from 65% to 35%. Wholesale purchasing is non-negotiable for profitable vending.
• Poor location selection: A machine in a location with 20 daily passers-by will never generate meaningful revenue. The vending machine profit calculator only works when the foot traffic supports it.
• Commission above 20%: At 20%+ commission, your net margin shrinks to the point where the operational effort is barely worth the return. Know your walk-away number.
• Inefficient routes: Driving 45 minutes to reach a single machine burns fuel and time that eats your profit. Cluster your machines geographically.
• Ignoring product mix data: Stocking products that do not sell ties up capital and wastes shelf space. Track what sells and adjust — the data is your best margin optimiser.
• Skipping contactless: Cash-only machines lose 20–30% of potential sales. A £200 card reader retrofit pays for itself within weeks.

“The vending machine profit calculator is not complicated. Revenue minus costs equals profit. The skill is in choosing the right location, buying stock at the right price, keeping commission reasonable, and running your route efficiently. Get those four things right and the numbers work. Get any of them wrong and they do not.”
