Cassette count should match refill schedule, expected withdrawals, and downtime tolerance. Planning capacity correctly prevents empty ATMs, emergency refills, and customer frustration. Start by browsing ATM Machines to compare models built for different transaction volumes and cash capacity needs.
How much money does an ATM hold?
Most retail ATMs can hold $20,000 to $40,000 per cassette, but owners usually load far less: most small operators keep $3,000 to $5,000 in the machine and refill based on how fast it dispenses. A retail cassette holds 1,000 or 2,000 notes, so a full cassette of $20 bills is $20,000 or $40,000, and machines with extra cassettes can hold more.
ATM Cash Cassette Capacity Comparison
Compare standard cassette sizes and maximum cash capacity across popular ATM models to determine how much cash each machine can hold.
| Model | Standard Cassette | Maximum Capacity | Max Value in $20 Bills |
|---|---|---|---|
| Genmega Onyx-W | 1 × 1,000 notes | 1,000 notes | $20,000 |
| Hyosung Halo II | 1 × 1,000 or 2,000 notes | 2 cassettes, 4,000 notes | $80,000 |
| Genmega G2500 | 1 × 1,000 notes | 4 × 2,000 notes | $160,000 |
| Genmega Onyx | 1 × 1,000 notes | 4 × 2,000 notes | $160,000 |
Note: Maximum dollar values assume every cassette is filled to capacity with $20 bills. Actual capacity depends on the installed dispenser configuration and cassette compatibility.
How much cash should I load?
Load enough to cover your busiest days until the next refill, plus a buffer. A simple formula:
Daily withdrawals x days between refills + a 20 to 30 percent buffer
For example, if a machine dispenses about $1,000 a day and you refill weekly, load about $7,000 plus $1,500 to $2,000 for weekends and busy days. Loading far more than you need ties up cash and raises your loss if the machine is broken into.
What Does Cash Capacity Mean in Real Operations?
Cash capacity is not only how much cash fits. It is also:
- How long the ATM can run before a refill
- How many days the location can tolerate lower cash levels
- How often emergency refills happen
More capacity reduces refill frequency, but only when it matches the actual withdrawal pattern.
How Do I Estimate Withdrawals Without Perfect Data?
A practical estimate uses:
- Foot traffic level
- Cash demand behavior at the location
- Nearby competitors and bank access
Even without exact numbers, weekly refill cadence can be planned using conservative assumptions, then adjusted after the first month.
How Does the Refill Schedule Change the Best Cassette Setup?
Refill schedule drives cassette planning.
- Weekly refill preferred: fewer cassettes can work
- Biweekly refill preferred: extra capacity becomes important
- Monthly refill preferred: a higher capacity setup becomes the safer default
This is why “refill schedule first, model second” works.
How Many Cassettes Are Enough for Common Location Types?
Examples that help planning:
- Small retail counter: stable, lower volume, weekly refill
- Convenience store or gas station: higher volume, more frequent refills
-
Hotel lobby or casino: higher peak swings, more capacity helps during events
A higher-volume location benefits from a machine with room for extra cassettes, such as the Genmega Onyx or a multi-cassette G2500 configuration. After estimating your refill schedule, compare the right options in ATM Machines to choose a cabinet and dispenser configuration that fits the volume.
What Mistakes Cause Empty ATMs?
Common mistakes:
- Planning for average days, not peak days
- Underestimating weekend patterns
- Choosing a setup that forces emergency refills during busy periods
Peak planning is safer than average planning.
What Else Matters Besides Cassette Count?
Capacity planning connects with:
- How fast staff can access the ATM for refill
- Where the ATM sits in the location
- Whether the site can support more frequent secure refills
Sometimes a simpler machine with an easier refill process beats a high-capacity machine that is hard to access. Once the refill schedule is clear, move from planning to purchase by selecting a machine that matches your volume in ATM Machines.
