Calculate your cost
Start with the example below, then replace the wattage, daily runtime, and rate with the numbers for your ice maker.
This setup uses about 18 kWh in a 30-day month.
Please enter valid values within the ranges shown.
| Schedule | Hours/day | Cost/month |
|---|---|---|
| Half runtime | 2 | $1.69 |
| Page example | 4 | $3.39 |
| Longer runtime | 6 | $5.08 |
Same 150-watt input and 18.83¢/kWh rate; only runtime changes.
Formula for the page example
0.15 kW × 4 hr × $0.1883 = $0.11 per day
Convert watts to kilowatts, multiply by the active hours used each day, then multiply by the electricity price in dollars per kWh. Multiply the daily result by 30 for the monthly estimate shown above.
How to read this estimate
Portable ice makers use steady, moderate wattage to freeze water quickly, usually running only when you need extra ice for a party or hot day.
Use this as a baseline until you can check the label or measure the ice maker directly. Model, settings, condition, climate, and household routine can all change the result.

Ways to spend less
- Turn it off and store extra ice in the freezer once full.
- Keep it in a cool, shaded spot away from direct sunlight.
- Use cold water to fill it so the freezing cycle is shorter.
