A countertop ice maker draws roughly 100 to 150 watts while running — about 0.1 to 0.15 kWh an hour. Used sensibly, meaning a couple of hours a day, that is 6 to 9 kWh a month, which at the U.S. average residential rate of 18.44 cents per kWh in May 2026 (EIA Electric Power Monthly, Table 5.6.A) works out to roughly $1.10 to $1.70 a month. Left running around the clock, the same machine uses 72 to 108 kWh and costs $13 to $20 a month — and most of that extra energy is wasted refreezing its own meltwater, because the basket is not refrigerated.
The Arithmetic, Step by Step
The formula is simple: watts ÷ 1,000 × hours = kWh, then kWh × your rate = cost. Take a typical 120-watt countertop machine:
| Usage pattern | Hours per day | kWh per month | Cost at 18.44¢/kWh |
|---|---|---|---|
| Occasional — a batch when you need one | 0.5 | 1.8 | ~$0.33 |
| Normal household use | 2 | 7.2 | ~$1.33 |
| Heavy — iced drinks all summer | 5 | 18 | ~$3.32 |
| Left on continuously | 24 | 86.4 | ~$15.93 |
Which is the honest headline here: an ice maker used as designed is one of the cheapest appliances in your kitchen to run. A dollar and change a month is less than a coffee maker, far less than a toaster oven, and a rounding error against an electric kettle used daily. The number only gets interesting if you leave the machine on.
Your Rate Matters More Than the Machine
The national average hides an enormous spread. From EIA's Electric Power Monthly for May 2026, average residential prices in cents per kWh:
| Region or state | ¢ per kWh (May 2026) | 2 hrs/day, monthly cost | Continuous, monthly cost |
|---|---|---|---|
| U.S. average | 18.44 | ~$1.33 | ~$15.93 |
| Louisiana | 14.15 | ~$1.02 | ~$12.23 |
| Florida | 15.17 | ~$1.09 | ~$13.11 |
| Texas | 16.44 | ~$1.18 | ~$14.20 |
| New England | 28.14 | ~$2.03 | ~$24.31 |
| California | 33.25 | ~$2.39 | ~$28.73 |
| Hawaii | 52.00 | ~$3.74 | ~$44.93 |
A Californian leaving an ice maker on continuously spends roughly what a Louisianan spends on two and a half machines' worth of running. The national average also moved up over the year — 18.44 cents in May 2026 against 17.37 a year earlier — so use your own bill's rate rather than a figure from an article if you want a number you can trust. Your utility statement gives it directly: total kWh divided into the energy portion of the bill.
Why Continuous Running Is Mostly Wasted
This is the part that turns an electricity question into a usage question. A countertop ice maker's basket is insulated but not refrigerated. Nothing is keeping the ice cold once the machine stops. It melts, and the meltwater drains straight back into the reservoir to be frozen again.
So a machine left running in a warm kitchen reaches a steady state where it is producing ice at roughly the rate the basket is melting it. The compressor runs, you pay for the electricity, and the amount of ice in the basket barely changes. That is where the difference between $1.33 and $15.93 a month goes — and it buys almost nothing.
The efficient routine is the one that also gets you more ice: run a batch, tip it into a zip bag, put the bag in the freezer, run another batch, then switch the machine off. Your freezer keeps ice frozen for essentially no marginal energy, because it is already running. The ice maker's job is production, not storage.

Consumption by Machine Type
| Machine | Typical running draw | Realistic monthly kWh | Notes |
|---|---|---|---|
| Countertop bullet | 100–150 W | 6–9 (2 hrs/day) | Cheapest to run of the lot |
| Countertop nugget | 120–180 W | 8–12 (2 hrs/day) | Auger motor adds a little load |
| Water dispenser (hot + cold) | 85–100 W cold, 400–500 W heating | 25–45 | The hot tank is the real consumer |
| Undercounter ice maker | 300–600 W | 60–150 | Runs against a refrigerated bin, continuously |
| Refrigerator ice maker | Shared with the fridge | Adds roughly 10–20% | Mostly the harvest heater, not the compressor |
Two things stand out. A water dispenser with a hot tank is a much bigger consumer than an ice maker, because keeping two liters of water at 185 to 195°F around the clock is genuine standby load — that is why several models let you switch the hot tank off, which is worth doing if you rarely use it. And an undercounter machine is in a different class entirely, because it is actually refrigerating a bin as well as making ice, and it never stops.
Why There Is No Efficiency Label to Compare
You cannot shop these on efficiency, and the reason is regulatory. The Department of Energy does set efficiency standards for automatic commercial ice makers — 10 CFR Part 431, Subpart H — where performance is measured in kilowatt-hours per 100 pounds of ice, a properly useful metric because it accounts for output as well as draw. Commercial buyers can also compare certified models through ENERGY STAR's certified commercial ice machine list.
Household countertop ice makers fall outside that rule. They carry no EnergyGuide label and no kWh-per-100-lb figure, so the only published numbers are nameplate wattage and a daily output claim — and the output claim is measured under favorable conditions. Practically, this means the efficiency difference between two $130 countertop machines is not something you can look up, and it is small enough not to matter. How you use the machine dominates.
Five Ways to Cut the Cost, in Order of Effect
- Run batches, not continuously. By far the biggest lever — it is the difference between about $1.30 and about $16 a month. Bag the ice into the freezer.
- Site it cool with clearance. These reject heat from the back and sides. A machine in a hot corner with three inches of wall behind it runs longer cycles for the same ice, so every pound costs more. Several inches of air makes a measurable difference.
- Use cool water. Inlet temperature directly sets how long the freeze takes. Cold tap water rather than water that has sat warm in a jug shortens every cycle.
- Descale it. Scale on the freezing fingers insulates them from the refrigerant, so cycles lengthen and the compressor runs more hours per pound of ice. This is an efficiency issue as well as a longevity one — see how to clean an ice maker.
- Unplug or switch off at the outlet. Standby draw on these is small, but a machine that is genuinely off cannot quietly restart a cycle because meltwater tripped a sensor.
Putting It in Context
Used the way it is designed to be used, a countertop ice maker is one of the least significant items on your electricity bill — under $2 a month in most of the country. It is not an appliance worth worrying about, and anyone telling you these machines are energy hogs is describing a machine left switched on for no reason.
