Estimates are based on the wattage and usage you enter. Actual electricity bills may also include fixed charges, taxes, fees, and other rate components.
How to use the calculator
Enter your electricity rate in USD per kWh. Add an appliance from the categorized list or create a custom appliance, then enter its wattage, quantity, hours used per day, and days used per month. Results update automatically.
Assumptions and limitations
Monthly energy is calculated from wattage × quantity × hours per day × days per month. Daily cost is the monthly estimate divided by 30, and annual cost is the monthly estimate multiplied by 12. Preset wattages are illustrative starting values and can be edited. Appliances such as refrigerators and air conditioners may cycle on and off, so actual consumption can differ. This estimate does not include fixed utility charges, taxes, or other bill adjustments.
