How Your Electric Bill Is Calculated
Our electric bill calculator estimates how much each appliance contributes to your monthly electricity costs by converting wattage and usage hours into kilowatt‑hours (kWh). Multiply that figure by your local cost per kWh to reveal an accurate energy budget.
In 2025, the average U.S. residential electricity rate is $0.15 per kWh, and the typical household spends about $135 per month. If your bill is higher, small tweaks—such as replacing incandescent bulbs with LEDs or scheduling heavy appliances for off‑peak hours—can cut consumption by up to 20 percent.
Electric Bill Calculator FAQ
What is a kilowatt-hour?
A kilowatt‑hour (kWh) equals 1,000 watts consumed for one hour. Utilities bill you in kWh, so lowering kWh usage directly reduces your electric costs.
Why is my electric bill higher than average?
High‑draw appliances like electric water heaters, space heaters, and clothes dryers can spike consumption. Our calculator pinpoints which devices use the most power so you can prioritize upgrades or reduce run‑time.
How can I lower my electricity costs?
Swap to ENERGY STAR® appliances, install smart plugs to curb phantom load, and adjust your thermostat by just 2 °F. Many households see 10‑30 % savings within a single billing cycle.
Does running appliances at night save money?
If your utility offers time‑of‑use (TOU) rates, operating dishwashers or EV chargers during off‑peak hours can cut the per‑kWh rate by 30 % or more.
