Formula and example
How the Electric Bill Cost Calculator USA – Estimate Appliance Electricity Cost Works
Watts show how much power an appliance needs. Dividing watts by 1,000 converts the number to kilowatts. Multiplying kilowatts by time gives kilowatt-hours, or kWh, which is the unit normally shown on an electric bill.
Example: a 1,500 watt space heater
A heater used for five hours per day at $0.18 per kWh uses 7.5 kWh daily and costs about $1.35 per day. Over 30 days, the estimated cost is $40.50.

Typical appliance electricity use
High-watt appliances can still be affordable when used briefly, while lower-watt appliances can add up when they run for many hours. Use the table as a starting point, then replace the wattage with the number printed on your appliance label for a more useful estimate.
| Appliance | Typical Watts | Common Use | Estimated Cost Level |
|---|---|---|---|
| Air Conditioner | 500–3,500 | 4–12 hours/day | High |
| Space Heater | 1,500 | 3–8 hours/day | High |
| Clothes Dryer | 2,000–5,000 | About 1 hour/load | High |
| Refrigerator | 100–800 | Cycles all day | Medium |
| Dishwasher | 1,200–1,800 | 1–2 hours/use | Medium |
| Gaming PC | 300–800 | 3–8 hours/day | Medium |
| TV | 50–200 | 3–6 hours/day | Low |
| Ceiling Fan | 50–100 | 4–12 hours/day | Low |
| LED Bulb | 8–15 | 4–8 hours/day | Very Low |
| EV Charger | 3,000–11,000 | Varies | High |

Common questions
Electric Bill Cost Calculator USA – Estimate Appliance Electricity Cost FAQs
How do I calculate electricity cost from watts?
Divide watts by 1,000 to get kilowatts, multiply by the hours used, and then multiply by your electricity rate per kWh.
How much does a 1,500 watt heater cost to run?
A 1,500 watt heater uses 1.5 kWh per hour. At $0.18 per kWh, it costs about $0.27 per hour.
How much does an air conditioner cost per day?
The cost depends on wattage, running time, and electricity rate. A 1,500 watt AC used for eight hours at $0.18 per kWh costs about $2.16 per day.
What does kWh mean on an electric bill?
kWh means kilowatt-hour. It measures the amount of electricity used over time and is the unit most utilities use for billing.
Is this calculator exact?
It provides a practical estimate. Actual charges can vary because of appliance cycling, utility fees, taxes, seasonal rates, and energy efficiency.
Where can I find my electricity rate?
Check your latest utility bill for the energy charge, supply charge, or price per kWh. Enter the combined rate that best reflects what you pay.
