Calculation details
Formula and methodology
See the exact math used to produce the result.
Cost = energy used or fuel consumed multiplied by your rate, adjusted for runtime, efficiency, or usage period.
Before acting
Assumptions to check
Review the real-world details that can change the estimate.
The key inputs are Running wattage, Estimated duty cycle, Electricity rate. Confirm watts, hours used, local electricity rate, duty cycle, seasonal use, and efficient alternatives before relying on the cost.

When to round up
Round up for older refrigerators, hot garages, dirty coils, or frequent door opening.
When to use this calculator
- Estimating monthly or yearly energy cost
- Testing watts, runtime, rate, and duty cycle changes
- Comparing efficient alternatives before buying or changing use
Tips for better estimates
- Use measured watts when possible, especially for appliances that cycle on and off.
- Enter the all-in local electricity rate from a recent bill.
- Rerun the estimate for seasonal use, lower runtime, or a more efficient alternative.
How this calculator is reviewed
This page is checked for inputs, formulas, examples, assumptions, topic fit, and related links. For this calculator, the review also covers watts, hours used, local electricity rate, duty cycle, seasonal use, and efficient alternatives.
The sample result is covered by automated tests, and the page links to related calculators and, where available, supporting guides so readers can check the assumptions before acting. If a formula, label, or assumption looks off, send the page URL and your inputs through the contact page.
Worked example
Example inputs: Running wattage: 180 watts; Estimated duty cycle: 35 %; Electricity rate: $0.16 /kWh. With those values, the calculator returns $7.36 per month. This refrigerator costs about $7.36.
Appliance wattage to estimated monthly cost
| 100 watts for 8 hours/day | About $3.90/month at $0.16/kWh |
|---|---|
| 500 watts for 8 hours/day | About $19.47/month at $0.16/kWh |
| 1,000 watts for 8 hours/day | About $38.93/month at $0.16/kWh |
| 1,500 watts for 8 hours/day | About $58.40/month at $0.16/kWh |
Example scenarios
- Use $7.36 per month as a cost snapshot, then rerun it with the device's measured watts and your local kWh rate.
- A heater, pump, refrigerator, or dehumidifier may cycle, so duty cycle can matter more than nameplate wattage.
- Seasonal use can change the yearly total; compare efficient alternatives before replacing equipment.
Quick reference chart
| Sample result | $7.36 per month |
|---|---|
| Daily kWh | 1.51 kWh |
| Yearly cost | $88.30 |
| Best next step | Use this estimate with the real watts, hours used, local electricity rate, duty cycle, and seasonal use. Compare efficient alternatives if the monthly or yearly cost is higher than expected. |
FAQs
Refrigerator Electricity Cost Calculator questions
Can I use this as my exact bill amount?
No. Use it as a planning estimate, then compare watts, hours used, local electricity rate, duty cycle, seasonal use, taxes, and fees with your actual bill.
What rate should I use?
Use the all-in local kWh rate from a recent bill when possible, including delivery charges, riders, taxes, and usage-based fees.
How can I lower the estimated cost?
Try fewer hours, a lower wattage device, better duty-cycle assumptions, off-peak use where available, or a more efficient alternative.
Is the refrigerator electricity cost calculator exact?
No. It is a cost planning estimate. Actual bills depend on all-in rates, taxes, fees, runtime, duty cycle, weather, and real equipment performance.
What inputs matter most?
Duty cycle can change the result more than the running wattage.
Should I add a cost buffer?
Yes. Rates, fees, runtime, weather, standby power, and real-world efficiency can make actual costs higher than a simple estimate.

Common planning mistakes
Using nameplate watts when actual draw is lower, ignoring duty cycle, using the advertised rate instead of the all-in local rate, and assuming seasonal use stays the same all year.
