ATM Machine ROI Calculator: Return on a Cash-Machine Investment
Work out the return on an ATM placement — both the total ROI and the annualized rate — from what you invested and the net surcharge income it returned over the years you ran it.

How the numbers shift across typical situations for this calculator:
| Scenario | Total ROI | Annualized ROI | Net profit |
|---|---|---|---|
| $4k → $7k over 3yr | 75.00% | 20.51% | $3,000.00 |
| $5k → $14k over 4yr (busy bar) | 180.00% | 29.36% | $9,000.00 |
| $4k → $4.5k over 3yr (slow spot) | 12.50% | 4.00% | $500.00 |
| $8k → $7k over 2yr (loss) | -12.50% | -6.46% | -$1,000.00 |
How This Calculator Works
Enter your total investment (machine, install, placement fees), the total net surcharge income over the period (after the location split and service costs, plus any resale value), and how many years you held it. The calculator returns total ROI, the annualized rate, and net profit.
The Formula
Return on Investment
V_start = amount invested, V_end = amount returned; annualized ROI = (V_end / V_start)^(1/n) − 1
Worked Example
Invest $4,000, take out $7,000 of net surcharge income over 3 years, and that's a 75% total ROI — about 20.5% a year annualized. ATM income is driven by transaction volume: a machine in a busy bar, club, or convenience store doing 6 to 10 surcharged withdrawals a day at a $3 surcharge can clear its cost in a couple of years, while a low-traffic spot may never break even after the location's share.
Key Insight
ATM ROI is a volume game with a financing twist. Two things make or break it: foot traffic (transactions per day at your surcharge) and the location split (busy venues often demand a cut of every surcharge, sometimes most of it). Also keep the vault cash separate from your investment — it's a float you get back, not a sunk cost, though it ties up capital. Reduce the total return to an annualized rate before comparing to other uses of the money: 75% over three years is a respectable ~20.5% a year, but it comes with cash-loading trips, jam clearing, and the risk of theft that a passive investment doesn't carry.
Frequently Asked Questions
How is ATM ROI calculated?
Net profit (returned minus invested) divided by the amount invested, times 100. $4,000 in and $7,000 of net surcharge income out is a 75% total ROI; over 3 years that's about 20.5% annualized.
What drives ATM profitability?
Transaction volume and the surcharge, minus the location's cut. A machine doing 6 to 10 surcharged withdrawals a day at a $3 surcharge earns far more than a low-traffic placement. Busy venues often negotiate a share of each surcharge, which can take most of the income.
Is the vault cash part of my investment?
No — treat it separately. The cash you load into the machine is a recoverable float you get back as customers withdraw it, not a sunk cost. It does tie up capital, but it shouldn't be counted as part of the amount invested for ROI.
What should 'total returned' include?
Net surcharge income after the location's split and any service or cash-delivery costs, plus any resale value of the machine at the end. Don't count gross surcharges if you share them with the venue or pay a processor.
Why annualize the return?
Because total ROI ignores time. A 75% return over 3 years (about 20.5%/year) is very different from 75% in one year. Annualizing lets you compare the ATM fairly against stocks, another machine, or any other use of the capital.

Methodology & Review
ROI is net profit as a percent of the amount invested; annualized ROI converts the total return to a yearly compound rate over the holding period. The amount returned should be net surcharge income (after the location split and cash-replenishment cost) plus any resale of the machine; vault-cash float is not separately modeled.
