Every kiosk vendor promises ROI. Almost none show the math. Here it is — the three lines that decide whether a kiosk pays for itself, with a worked example you can rerun on your own numbers in two minutes.
The only three lines that matter
1. Upsell revenue. The biggest line. Guests ordering on a screen accept well-timed add-on suggestions 30–45% of the time. On a typical QSR menu, automated upselling adds $3–5 to the average kiosk order — mostly in high-margin items like sides, drinks and combo upgrades.
2. Labour savings. Kiosks take orders so people don’t have to. Most single locations redeploy 4–6 counter hours a day to the line, the pass and the dining room. Value those hours at your loaded wage — they’re either overtime you stop paying or capacity you gain at peak.
3. Software cost. On a flat-fee model, this is fixed and known: one subscription per kiosk per month. On a commission model, it grows with your success — more on that below.
A worked example
Take a mid-volume QSR: 320 orders a day at a $16 average check, running two kiosks that handle ~60% of walk-in orders.
The payback question almost answers itself: at ~$860 of daily impact, the month’s subscription is covered before the end of day one. Even if you cut every assumption in half, payback lands inside the first week. Don’t take our defaults — run your own numbers in the calculator.
What actually moves the numbers
- Menu structure. Combos, sides and desserts give the engine something to sell. A menu with natural pairings out-earns a flat one.
- Kiosk share. Placement and staff guidance decide how many orders flow through screens. 60% is typical by week three; strong operators reach 80%+.
- Take-rate. Static prompts fade below 20%; suggestions that adapt to the order and daypart hold 30–45% indefinitely.
One warning: commissions eat the upside
A 3–5% per-order commission looks small next to the numbers above — until you notice it scales with the kiosk’s success. On our worked example, 4% of kiosk revenue is roughly $4,600 a month, versus $378 flat. The better the kiosk performs, the worse the commission deal gets. Whatever vendor you choose, model both structures at your real volumes before signing.
