- Households comparing appliance and electricity costs
- Worth noticing
- It ranks appliances by annual cost rather than wattage and exposes the wattage, usage, and rate assumptions behind each estimate.
Field notes
The calculator separates appliance power draw from actual usage by allowing a daily-hours input, then applies a selected jurisdiction’s residential rate. Its rankings include categories such as electric furnaces, vehicle charging, heat pumps, and pool pumps, while the methodology notes that fixed charges, taxes, and time-of-use pricing are excluded. State comparisons cover all 50 states plus the District of Columbia.
