The real numbers - **Snack machine:** ~150 kWh/year — about $45/year at 30c/kWh. Basically an LED strip and a fan. - **Cold drink machine (older):** 2,500–3,500 kWh/year — $750–$1,050/year. - **Cold drink machine (modern R290):** 1,200–1,800 kWh/year — $360–$540/year. - **Combo:** 1,500–2,200 kWh/year — $450–$660/year. - **Coffee (bean-to-cup):** 400–800 kWh/year — $120–$240/year.
How to cut consumption 1. **LED lighting** — most modern machines already have it; older ones can be retrofitted. 2. **Night mode / occupancy sensors** — fridge cycles down after hours. 3. **R290 refrigerant** — 30–40% more efficient than R134a. 4. **Door gasket check** — a $30 gasket can save $200/year in power.
Site owners hosting a free vending machine usually cover power ($3–$10/week for a modern drink unit).
Electricity is a state-by-state number
Commercial electricity rates differ across the National Electricity Market and the WA and NT systems, so the same machine costs noticeably more to run in some states than others. Rather than quoting a single national dollar figure that will be wrong somewhere, work it out from your own bill: take the machine's annual kWh estimate and multiply by your c/kWh rate including any demand charges.
What changes the kWh number most:
- Refrigerant and deck age. A modern R290 deck draws materially less than a decade-old R134a unit.
- LED versus fluorescent lighting, and whether lighting runs 24 hours.
- Night set-back or an occupancy timer on sites that are empty overnight — one of the easiest savings available, and it does not affect daytime sales.
- Position. Direct sun, a hot western wall, or no clearance behind the machine all force the compressor to work harder. This is free to fix.
- Climate. The same machine uses more energy in Darwin or Townsville than in Hobart or Ballarat.
Who pays
Under free placement the site host supplies power and the operator supplies everything else; that is the trade. It is worth stating plainly in the site agreement so it never becomes a dispute later.

Frequently asked questions
- How much electricity does a vending machine use?
- It depends on refrigeration type, lighting, climate and whether night set-back is enabled. Work from the machine's annual kWh figure multiplied by your own commercial rate rather than a national average.
- Do vending machines use a lot of power?
- A refrigerated machine runs continuously, so it is a real but modest line item — comparable to a commercial fridge. A modern R290 deck with LED lighting and night set-back is significantly cheaper to run than an older unit.
- Who pays for electricity on a free-placed vending machine?
- The site host supplies power; the operator supplies, stocks, services and insures the machine. It should be written into the site agreement.
