The short answer
It depends on your attendance, how cash-heavy the event is, and how long it runs. Start by asking whether you have cash-only entry, a cash bar, or cash-only vendors. Then estimate how many guests will need cash and how much they'll take out. Large fairs often run several ATMs at once, placed near the entrance, food, and bar areas.

You've booked the bands. You've lined up the vendors. You've planned parking, security, and restrooms.
Then event day comes, and the line at the only ATM wraps around the food court. Or worse, the machine runs dry by 3 p.m. Your cash-only vendors sit idle. Guests leave early to find cash and never come back.
Cash planning is easy to overlook, and it's one of the things guests remember. Here's how to get it right.
Why do events need ATMs?
Because events are one of the last places where cash still rules.
- Many vendors are cash-only, or strongly prefer cash to avoid card fees and slow connections.
- Cash lines move faster than card lines when a crowd is packed in.
- Guests who can't get cash can't buy. And many of them won't leave to find it.
The Federal Reserve's 2026 study found more than 90% of consumers have no plans to stop using cash. At an event, that shows up in every food line.
How much cash do events really go through?
More than most organizers expect.
A county fair in Washington state reported in 2015 that its ATMs dispensed nearly $200,000 over its opening weekend from six machines, and $524,000 over the full run of the fair. A large state fair in New York planned for 10 to 15 ATMs.
Your event may be smaller. But those numbers show how fast cash moves when thousands of people are buying food, drinks, and crafts in one place.
How many ATMs does your event need?
There's no one formula, but these questions get you most of the way there.
1. How many people will attend, and over how many days? A one-day event with 2,000 guests is very different from a three-weekend faire.
2. How cash-heavy is your event? Each "yes" below raises your need: - Is there a cash-only entry or parking fee? - Is there a cash-only bar? - Are many vendors cash-only? - Is there no card acceptance at all?
3. When are the rush hours? Opening hours and meal times are when lines form. Plan for the peak, not the average.
4. How spread out is the event? One big field may need machines in more than one spot, so guests aren't walking across the grounds to wait in line.
Bring these answers to your ATM provider. A good provider will turn them into a recommendation for how many machines, how much cash, and where to put them.
Where should the ATMs go?
- Near the entrance. Guests stop for cash on the way in, before they reach the vendors.
- Near food and bar areas. That's where the most cash changes hands.
- Near cash-only vendors, if they're grouped together.
- Spread out, not stacked. Two machines in two places often beat two machines side by side.
- In lit, visible, staffed areas, for safety.
- Near power. Our machines connect by wireless cellular service, so no phone line or internet is needed. They do need power. Sites without outlets may need a generator.
What should you ask your event ATM provider?
- How many machines do you recommend for my event, and why?
- How will you keep them full through the busiest hours?
- Who is on-site if a machine has a problem?
- What security do you bring for the machines and the cash?
- What do you need from me: power, space, access times?
- How is pricing set, and who earns what? (We explain how event pricing works in what an event ATM costs.)
How do you avoid an event ATM disaster?
Book early. Machines, cash, and staff all have to be scheduled. Popular spring and fall weekends fill up.
Give honest attendance numbers. Overestimating can be just as costly as underestimating. One event ATM operator told ATM Marketplace about a promoter who first projected 100,000 to 150,000 people, then 75,000, and by the time the operator arrived, 25,000 to 50,000. Honest numbers help your provider bring the right amount of cash and machines.
Tell vendors ahead of time. Let cash-only vendors know where the ATMs will be. Put the locations on your event map.
Plan for the peak. The machine that's fine at 11 a.m. can run dry at 6 p.m.
Why work with a local event ATM company?
Events don't run on a schedule you can move. When a machine needs cash or has an issue during the rush, you need someone who can get there.
We're Alabama-owned and based in Birmingham. We bring wireless machines, keep them loaded through the event, and plan cash around your crowd. Learn more about mobile ATMs for events.
Your guests will never thank you for having enough ATMs. But they'll definitely remember if you didn't.
Common questions
It depends on attendance, event length, and how cash-heavy the event is. Cash-only entry, cash bars, and cash-only vendors all raise the need. Large fairs often use several machines; a large state fair, for example, planned for 10 to 15.
As early as you can, especially for busy spring and fall weekends. Machines, cash, and staff have to be scheduled, and popular dates fill up.
Near the entrance, near food and bar areas, and anywhere cash-only vendors cluster. Spread them out so one line doesn't block foot traffic, and place them where they're lit and visible.
They need power. Our event ATMs connect by wireless cellular service, so they don't need a phone line or internet, but they do need a power source. Outdoor sites without outlets may need a generator.
They can. When guests can get cash on-site, they can buy from cash-only vendors instead of leaving to find an ATM or skipping the purchase.
