🛠️ How to Use the Appliance Cost Calculator
Using the Appliance Cost Calculator is incredibly simple and doesn’t require any technical knowledge. Here’s how it works:
Step-by-Step Instructions:
- Enter Appliance Wattage (W):
This is the power consumption of your device. You can usually find it on the label of your appliance. For example, a space heater might consume 1500 watts. - Enter Hours Used Per Day:
Input the average number of hours the device runs daily. For instance, 3.5 hours for a fan used in the evening. - Enter Electricity Rate (¢/kWh):
You can find your electricity rate on your utility bill. It’s usually listed in cents per kilowatt-hour. For example, 13.5¢/kWh is a common rate in many areas. - Click “Calculate”:
Instantly see your estimated daily, monthly, and yearly electricity cost. - Reset as Needed:
Use the reset button to clear all fields and try different calculations.
📊 Example Calculation
Let’s say you want to calculate the cost of running a 1500W heater for 4 hours daily with an electricity rate of 15¢ per kWh:
- Wattage: 1500
- Hours per Day: 4
- Rate: 15
The results would be:
- Daily Cost: $0.90
- Monthly Cost: $27.00
- Yearly Cost: $328.50
This can help you decide whether it’s worth using that heater or looking into a more efficient model.

🧮 Behind the Scenes: How the Calculation Works
The formula used by the calculator is straightforward:
sqlCopyEditEnergy Cost = (Wattage × Hours per Day ÷ 1000) × (Electricity Rate ÷ 100) This converts watts to kilowatt-hours (kWh) and multiplies by your rate.
Then:
- Daily Cost: Calculated directly
- Monthly Cost: Daily Cost × 30
- Yearly Cost: Daily Cost × 365
