Appliance Operating Cost Calculator
Calculate how much your appliances cost to run and find potential savings
Energy Saving Tips
Reduce operating costs:
- Use energy-efficient appliances (look for ENERGY STAR rating)
- Turn off appliances when not in use
- Use power strips to eliminate phantom loads
- Maintain appliances for optimal efficiency
Consider solar: The average solar panel system can offset 100% of your electricity usage.
| Metric | Appliance 1 | Appliance 2 | Difference |
|---|---|---|---|
| Wattage | 0W | 0W | 0W |
| Daily Cost | $0.00 | $0.00 | $0.00 |
| Monthly Cost | $0.00 | $0.00 | $0.00 |
| Annual Cost | $0.00 | $0.00 | $0.00 |
| Annual kWh | 0 | 0 | 0 |
Upgrade Considerations
When to upgrade: Consider replacing appliances when the energy savings would pay for the new appliance within 3-5 years.
Look for: ENERGY STAR certified appliances typically use 10-50% less energy than standard models.
Rebates: Check for utility company rebates that can offset the cost of energy-efficient appliances.

Complete Guide: Appliance Operating Cost Calculator
Learn how to track energy usage, calculate expenses, and save money on electricity bills with our easy-to-use calculator
Did you know that your home appliances could be costing you hundreds or even thousands of dollars each year in electricity? Understanding how much each appliance costs to run is the first step toward smarter energy usage and significant savings on your utility bills.
In this comprehensive guide, we'll walk you through everything you need to know about appliance operating costs, complete with simple examples, easy formulas, and our interactive calculator that does all the math for you.
What Is Appliance Operating Cost?
Appliance Operating Cost refers to how much money you spend to run an electrical appliance over a specific period. This cost depends on three main factors:
- Appliance Wattage: How much power the appliance uses
- Usage Time: How many hours you use it each day
- Electricity Rate: How much your electricity company charges per kilowatt-hour (kWh)
Simple Example:
A 100-watt light bulb running for 5 hours each day at $0.15 per kWh:
- Daily cost: About 7.5 cents
- Monthly cost: About $2.25
- Yearly cost: About $27.38
That's just one light bulb! Imagine adding up all your appliances...

The Simple Formula Behind the Calculator
The Core Formula:
Where wattage is in watts, hours is daily usage, and electricity rate is in dollars per kWh
Let's break this down step by step:
Step 1: Convert Watts to Kilowatts
Electricity is billed in kilowatt-hours (kWh), not watt-hours. Since 1 kilowatt = 1000 watts:
Example:
A 1500-watt space heater:
1500 watts ÷ 1000 = 1.5 kilowatts
Step 2: Calculate Daily Kilowatt-hours
Multiply kilowatts by the number of hours used each day:
Example:
Using our 1.5 kW space heater for 4 hours daily:
1.5 kW × 4 hours = 6 kWh per day
Step 3: Calculate Daily Cost
Multiply daily kWh by your electricity rate:
Example:
At $0.15 per kWh:
6 kWh × $0.15 = $0.90 per day
Step 4: Calculate Monthly and Yearly Costs
Yearly Cost = Daily Cost × 365
Complete Example:
For our space heater used 30 days a month:
- Monthly: $0.90 × 30 = $27.00
- Yearly: $0.90 × 365 = $328.50
That's over $300 per year just for one appliance!
Pro Tip: Understanding Your Electricity Bill
Your electricity rate is usually listed on your utility bill as "cost per kWh." This rate varies by location, time of day (peak vs. off-peak), and season. The U.S. national average is about $0.15 per kWh, but it can range from $0.10 to over $0.30 depending on where you live.
Common Appliance Wattages
Here's a quick reference table for typical appliance wattages:
| Appliance | Typical Wattage | Typical Daily Use | Estimated Monthly Cost* |
|---|---|---|---|
| Air Conditioner | 1500-3500W | 8 hours | $54-$126 |
| Refrigerator | 150-250W | 24 hours | $16-$27 |
| Washing Machine | 500W | 1 hour | $2.25 |
| LED TV | 60-150W | 4 hours | $1.08-$2.70 |
| Desktop Computer | 150-300W | 8 hours | $5.40-$10.80 |
| LED Light Bulb | 9-15W | 5 hours | $0.20-$0.34 |
| Clothes Dryer | 3000W | 1 hour | $13.50 |
*Based on $0.15/kWh and typical usage patterns
How to Use Our Calculator (Step by Step)
Step 1: Select Your Appliance
Choose from common appliances or create a custom one. Each selection automatically fills in typical wattage values.
Step 2: Enter Usage Details
- Appliance Wattage: Find this on the appliance label or in the manual
- Hours Used Per Day: Be realistic about your actual usage
- Days Used Per Month: Most people use 30 for appliances used daily
Step 3: Enter Your Electricity Rate
Check your latest electricity bill for the cost per kWh. Use the slider to adjust and see how different rates affect costs.
Finding Your Electricity Rate
Look for "kWh" or "kilowatt-hour" on your bill. The rate is usually shown as something like "$0.15 per kWh." If you can't find it, use the U.S. national average of $0.15/kWh as a starting point.

Putting It All Together: A Real Case Study
The Smith Family's Energy Audit
The Smith family used our calculator and discovered:
- Their 15-year-old refrigerator was costing $35/month
- A new ENERGY STAR model would cost $15/month
- Annual savings: $240
- New fridge cost: $800
- Payback period: 3.3 years
They also found that leaving 5 devices on standby was costing $75/year. By using power strips, they eliminated this cost entirely.
