Estimates only — not financial advice. Preset wattages are typical values; real devices vary. Taxes and utility fees are not included.
How to estimate your electricity bill
- Add your appliances: pick a preset (its typical wattage fills in automatically) or choose "Custom appliance" and enter the wattage from the device's label. Set hours it runs per day.
- Adjust anything — wattage and hours on each row stay editable, and rows can be removed. Three common appliances are loaded to start.
- Enter your rate per kWh (from your utility bill) and the number of billing days.
- Watch the totals update live: total kWh, your estimated bill, and a per-appliance cost breakdown showing exactly where the money goes.
Frequently asked questions
How is my electricity bill calculated?
Each appliance uses watts ÷ 1000 × hours of use = kWh, and your utility multiplies total kWh by your rate per kWh. This estimator walks through that math appliance by appliance.
What is a kilowatt-hour (kWh)?
The energy of 1,000 watts running for one hour — a 100-watt bulb left on for 10 hours uses exactly 1 kWh.
What uses the most electricity in a home?
Heating and cooling dominate — space heaters, dryers, and air conditioners draw 1,000+ watts. Refrigerators use less per hour but run 24/7.
How can I lower my electricity bill?
Target the biggest kWh consumers first: shorter dryer and space-heater run times, and a warmer AC setpoint, beat unplugging phone chargers by a wide margin.
Are these wattage figures exact?
No — they're typical values to start from. Every preset's wattage is editable, and you can add custom appliances with your device's real rating.
Is this financial advice?
No. Planning estimates only.
