What does a standalone ice maker cost to run?

Run the numbers on your own use

Change any of these and the figures update. The defaults are the typical case described above; your rate is the input that moves the answer most.

Why this is lower than the number you will see elsewhere

Almost every published answer to this question multiplies the rating on the label by the hours the appliance is switched on. For a standalone ice maker that gives 3,066 kWh a year, or $562.

Cycles between freezing a batch and harvesting it, and then keeps the finished ice frozen — so it never truly stops while switched on.

The arithmetic, step by step

Nothing here is hidden, so you can check it or change it. Working in the order the formula runs:

1. 350 W — what it draws while it is actually drawing. This is the rating on the plate.
2. × 45% — the share of its in-service time it is really pulling that. Cycles between freezing a batch and harvesting it, and then keeps the finished ice frozen — so it never truly stops while switched on.
   That gives 158 W averaged across the hours it is on.
3. × 24 hours a day × 365 days — An undercounter unit kept switched on year round.
   158 × 24 × 365 ÷ 1,000 = 1,380 kWh a year.
4. × 18.34¢ — the US average residential rate for June 2026.
   1,380 kWh × 18.34¢ = $253 a year.

Change any assumption in the calculator above and every figure on this page moves with it. The two that matter most are your rate, which varies 4× across the country, and the hours — the duty cycle is a property of the appliance, but the hours are a property of you.

How sensitive is that number?

A single figure invites more confidence than it deserves. Here is the same appliance under assumptions either side of the default, so you can see how much of the answer is the appliance and how much is the guess about how you use it.

Everything else held at the default. The spread here is the honest error bar on the headline figure.

What it costs per hour, day and month

The thing worth knowing

Making ice is expensive twice: freezing the water, and then refrigerating the bin to stop what you made from melting. Most standalone machines have an uninsulated or lightly insulated bin, so a large fraction of the ice melts and is remade continuously. A unit left on through winter can cost more than the freezer it sits next to.

What it costs in your state

The appliance is the same everywhere; the rate is not. Running this standalone ice maker costs $727 a year in Hawaii and $181 in Nevada — a difference of 4×.
