How to Calculate Appliance Electricity Cost
Watts measure appliance power. Kilowatts are watts divided by 1000. kWh means kilowatt-hour. Electric companies usually bill customers based on kWh usage, so a watts to kWh cost calculator helps convert appliance power into a real estimated cost.
Example: 1,500 Watt Space Heater
A 1,500 watt space heater used for 5 hours per day:
1,500 ÷ 1,000 = 1.5 kW
1.5 × 5 = 7.5 kWh per day
7.5 × $0.18 = $1.35 per day
$1.35 × 30 = $40.50 per month
Average Electricity Cost by Appliance
| Appliance | Typical Watts | Common Use | Estimated Cost Level |
|---|---|---|---|
| Air Conditioner | 500–3500 watts | 4–12 hours/day | High |
| Space Heater | 1500 watts | 3–8 hours/day | High |
| Clothes Dryer | 2000–5000 watts | 1 hour/load | High |
| Refrigerator | 100–800 watts | 24 hours/day | Medium |
| Dishwasher | 1200–1800 watts | 1–2 hours/use | Medium |
| Washing Machine | 400–800 watts | 1 hour/use | Low to Medium |
| TV | 50–200 watts | 3–6 hours/day | Low |
| Gaming PC | 300–800 watts | 3–8 hours/day | Medium |
| Ceiling Fan | 50–100 watts | 4–12 hours/day | Low |
| LED Bulb | 8–15 watts | 4–8 hours/day | Very Low |
| Laptop | 45–100 watts | 4–10 hours/day | Low |
| EV Charger | 3000–11000 watts | Varies | High |
What Is an Electric Bill Cost Calculator?
An electric bill cost calculator helps you estimate appliance energy cost based on watts, hours used, days used, and your electricity rate. This electricity cost calculator is useful for homeowners, renters, apartment residents, students, families, and anyone trying to reduce their monthly electric bill. You can use it as an appliance electricity cost calculator, kWh cost calculator, monthly electric bill estimator, electricity usage calculator, and cost to run appliance calculator.
How Much Does It Cost to Run an Appliance?
The cost to run an appliance depends on wattage, usage time, and electricity rate per kWh. Higher-watt appliances like AC units, electric heaters, dryers, ovens, water heaters, and EV chargers usually cost more than TVs, laptops, fans, and LED lights. A dryer electricity cost calculator or refrigerator electricity cost per month estimate can help you understand where your electricity bill is going.
How Much Does AC Cost Per Day?
AC electricity cost depends on unit size, wattage, climate, insulation, thermostat setting, and hours used. For example, a 1500 watt AC used for 8 hours per day at $0.18 per kWh costs about $2.16 per day. This is why searches like how much does AC cost per day and AC electricity cost calculator are useful for people in hot states.
How Much Does a Space Heater Cost to Run?
Many portable space heaters use around 1500 watts. At $0.18 per kWh, a 1500 watt heater costs about $0.27 per hour. If used 5 hours per day, the estimated cost is about $1.35 per day or $40.50 per month. This space heater cost calculator can help estimate how much a space heater costs to run before your bill arrives.
How Much Does a Refrigerator Cost Per Month?
Refrigerators run throughout the day but cycle on and off, so actual usage depends on age, size, efficiency, room temperature, door openings, and temperature settings. Newer ENERGY STAR-style refrigerators usually use less electricity than older units. Use the refrigerator preset as a starting point and adjust the wattage if you know your model’s actual rating.
Why Is My Electric Bill So High?
- Running AC for long hours
- Using electric heaters
- Old refrigerator or freezer
- Electric dryer usage
- Poor insulation
- High electricity rate
- Pool pump or water heater
- EV charging
- Standby power from electronics
How to Lower Your Electric Bill
- Use a programmable thermostat
- Replace old bulbs with LED bulbs
- Clean AC filters
- Seal air leaks
- Run full loads in washer and dishwasher
- Air dry clothes when possible
- Turn off unused electronics
- Use smart plugs
- Compare electricity plans where available
- Reduce heater or AC runtime by one hour per day
Electric Bill Calculator FAQs
How do I calculate electricity cost from watts?
Divide watts by 1000 to get kilowatts, multiply by hours used, then multiply by your electricity rate per kWh.
How much does a 1500 watt heater cost to run?
A 1500 watt heater uses 1.5 kWh per hour. If your electricity rate is $0.18 per kWh, it costs about $0.27 per hour to run.

kWh means kilowatt-hour. It measures how much electricity you use over time. Electric companies usually charge based on the number of kWh used.
What appliances use the most electricity?
Common high-electricity appliances include central air conditioners, electric heaters, clothes dryers, water heaters, ovens, pool pumps, and EV chargers.
Does unplugging appliances save electricity?
Yes, unplugging some appliances can reduce standby power usage, especially electronics, chargers, gaming consoles, and devices with always-on displays.
Is this calculator accurate?
This calculator provides an estimate. Actual cost may vary based on appliance efficiency, usage pattern, thermostat setting, local electricity rate, and utility fees.
Where can I find my electricity rate?
You can usually find your electricity rate on your electric bill. Look for price per kWh, energy charge, supply charge, or delivery charge.
How much does a dryer cost to run?
Dryers often use 2000 to 5000 watts. The cost depends on wattage, load time, and your electricity rate.
How can I reduce AC electricity cost?
