About the Electricity Bill Calculator

The bill follows a three-step chain: power × time = energy, energy × rate = cost. A 1,500 W space heater on 3 hours a day burns 4.5 kWh daily; over 30 days that is 135 kWh, or $20.25 at $0.15/kWh — a meaningful share of a typical residential bill.

Finding the Biggest Savings

Resistive loads — space heaters, electric dryers, water heaters — dominate because they convert current directly to heat. Replacing or reducing them moves the needle far more than LED swaps. Use this calculator per appliance to rank where the money actually goes.
