What Does It Cost to Run a Refrigerator in Montana?
This page estimates the energy-only cost to run a refrigerator in Montana using a typical compressor-cycle refrigerator, an average load of 180 watts, and a typical runtime of 8 hours/day.
Key metrics
| Metric | Value |
|---|---|
| Average wattage assumption | 180 W |
| Typical usage assumption | 8 hours/day |
| Estimated monthly electricity use | 43.2 kWh |
| Estimated monthly cost | $5.76 |
| Estimated yearly cost | $70.06 |
Refrigerator cost vs U.S. average
At the statewide average residential rate, running a refrigerator in Montana costs less per month by $2.12 than the same usage pattern priced at the current U.S. average electricity rate.
How much electricity does a refrigerator use?
This estimate uses a typical wattage range of 100-250 W and a modeling assumption of 180 watts for 8 hours/day. Using the formula kWh = (watts × hours) / 1000, that works out to 1.44 kWh per day, 43.2 kWh per 30-day month, and 525.6 kWh per year.
Refrigerators cycle on and off during the day, so the average running load is lower than peak startup wattage. In Montana, that energy is priced using the statewide residential average of 13.33 ¢/kWh, with a national benchmark of 18.24 ¢/kWh for comparison.
Refrigerator operating cost estimate in Montana
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 0.18 kWh | $0.02 |
| Per day | 1.44 kWh | $0.19 |
| Per month | 43.2 kWh | $5.76 |
| Per year | 525.6 kWh | $70.06 |
These estimates isolate electricity usage only. Real utility bills can be higher because delivery charges, taxes, seasonal pricing, and fixed monthly fees are not included in this appliance model.
What changes the cost the most?
The biggest cost drivers for a refrigerator are the local electricity rate and real-world usage intensity. For this appliance, the main swing factors are appliance age, door-opening frequency, garage vs indoor placement.
If your usage is lighter or heavier than the assumption on this page, the linked state calculator and usage-cost pages below are the fastest way to model a custom scenario with the same state electricity rate.
