# When you’re shopping for new appliances, one of the biggest questions to ask is “How much does my appliance cost to run?” Knowing the answer will help give you a picture of the true cost of the appliance over its lifetime and help you weigh the pros and cons of your purchase. You need an electricity cost calculator.

## Three Steps: Electricity Cost Calculator Gathering the Right Information

### 1. Figuring Out Your Electricity Costs

**Electric Supply: 0.0925 x 583 kWh****Distribution Charge: 0.06236 x 583 kWh****Renewable Energy Charge: 0.0005**

**In this case, that’s $0.15536 x 583 kWh, which comes out to $90.57.**

### 2. Figuring Out How Much Electricity Your Appliance Uses

### 3. Figuring Out How Often You Use Your Appliance

If you only used that light bulb for one hour per month, it would be easy to figure out how much you are paying to use it: You just need to multiply the cost of your electricity per kWh by the amount of kilowatt-hours of energy the device uses. In the case of our light bulb, the math looks like this:

**$0.15536 x 0.1 kWh = $0.015536, or 1.55 cents to operate the light bulb.**

If you only use that light bulb for one hour each month, that’s your total cost. However, you probably use that light bulb for many hours each day and many days per month, so you have to figure out how many hours per month you use it. In most cases, you can estimate this. Just think about how long you leave that light on each day, and how many days per month you repeat that usage.

If you’re really meticulous, you might allow more or less usage on weekends than weekdays in your estimate. And if you’re *very* detailed, you could keep a log of usage to know for sure how often you use it for a week or a month.

Once you estimate your usage, you just need to multiply the total number of hours of use by the cost per kWh to operate it. If you use your 100-watt bulb for eight hours each day, every day, you can figure out the cost of usage as illustrated below:

**Electricity Cost Calculator:**

**$0.15536 x 0.1 kWh x 8 hours = $.124288, or 12.42 cents per day****$0.15536 x 0.1 kWh x 8 hours x 7 days = $.870016, or 87 cents per week****$0.15536 x 0.1 kWh x 8 hours x 30 days = $3.72864, or $3.73 per month**

**are averages**based on the typical wattage used by each type of appliance listed above. For better results in your calculations, check the actual wattage drawn by your appliance — or the one you’re considering buying.

Likewise, you can use the information above to get more accurate results for your personal costs by figuring out what you actually pay for electricity at your house. The national average is just that: an average. This means that you pay either more or less — and perhaps by a lot. It’s worth it to calculate your own electricity rate as described in the steps above and use it to see how much each of these appliances will cost you. To do so, simply take the kWh number from the table for the appliance you’re considering and multiply it by your actual electric rate.

For example, if you want to know how much a NewAirMiniDryer26W clothes dryer will cost to operate per hour, but you know that your electricity costs $0.155 instead of $0.12 per kWh, calculate your costs like this:

**1.4 kWh x $0.155 = $0.217, or 21.7 cents per hour**

From there, you can estimate how long a load takes to dry and how many loads you do per month to figure out your personal monthly cost for running the mini clothes dryer.
