FAQ
How do I find my electricity rate?
Check your electricity bill for the rate per kWh. Look for "energy charge" or "usage charge." If you see multiple tiers, enable tiered rates and enter each tier's rate and threshold.
What uses the most electricity?
Heating and cooling typically account for 40-50% of home energy use. Electric water heaters, dryers, and EV chargers are also high consumers. Refrigerators use moderate power but run 24/7.
Why is my estimate different from my bill?
Bills may include additional fees (fuel adjustment, delivery charges, taxes) not captured here. Also, actual usage varies with seasons, occupancy, and appliance age. Use this as a baseline estimate.
