## How Many Amps Does A Microwave Use?

**Microwaves typically use between 5.4 and 10 amps with a power rating of 600 to 1200 watts. Researching product details and calculating the amperage of your microwave is important. It allows you to determine how many amps it consumes and the cost of running it.**

### Amperage and Voltage

To begin with:

**An amperage (amp) is an electrical power measurement unit**. It describes the **rate at which electrical current flows through a system.**

Next:

**Voltage** can be described as **the pressure required to propel electrons within a conducting path or electric field.**

What’s more?

Higher amperage usually means **more power**, but **amperage and voltage work together** to produce the final output.

## Microwave Amp Usage Calculation: Step-by-Step Process

### Step 1: Check Product Specifications

First off:

Since **not all microwaves are the same**, you should **know specific details **about your microwave before calculating.

Now get this:

The **wattage and voltage** of your microwave are the two most important things you should know. Although wattage varies widely, **most microwaves operate at 120 volts** with minor variations.

**The amount of amps your microwave uses is determined by your microwave’s wattage and volt outlet.**

**Pro tip:**

You can **learn essential information about your microwave** by checking the **user manual**.

If the manual is not available, do some **research online** or **contact customer support for your microwave model.**

Warning:

If you consult the internet for this information, **be careful to avoid getting watt and voltage values for models with similar features but different power specifications. **** **

### Step 2: Divide the Wattage by the Voltage

Here’s the thing:

You can get the **exact amperage** your microwave uses by **dividing the wattage by the voltage**.

For instance:

If your microwave is rated at **600 watts** with a **voltage of 120**, it will use **5 amps**.

Similarly:

**An 800-watt microwave with a 120-volt capacity requires ~**7 amps**. While a **1200-watt appliance needs 10 amps at a 120-Volt Rating**.**

**You get the point, right?**

Note:

These amperage results have been** rounded up to the nearest whole number **to keep things simple.

Also:

**High-wattage microwaves heat food quickly** and save time. But they are more **expensive** and **consume more electricity** than low-wattage models.

## How Much Does It Cost to Use a Microwave?

Fact:

**Microwaves use electricity **and that** costs money**. However, since most of these appliances** consume little electricity**, it has minimal effect on the power bill.

Here’s how it goes:

To determine the **cost of running a microwave**, first **identify the unknown variables. **Specifically, the **cost of electricity** and the **average daily use time**.

These figures may vary depending on **how often you use your appliance**.

Once you identify the variables, you can **calculate how much it costs** to use a microwave daily, monthly, or yearly.

### For Example…

**How many amps does a 1000-watt microwave consume? And how much will it cost me daily/monthly/yearly at an average price of $0.01/KWh for energy?**

Let’s find out:

A **1000-watt** microwave **rated at 120V** consumes ~**9 amps**.

Using an estimated **daily usage of 15 minutes** and the **cost of electricity at $0.10/KWh (10 cents per KWh)**, we will calculate the cost of using a microwave with the steps below:

**Step 1:**Determine the average daily use: let’s say**15 minutes.****Step 2:**Calculate the daily wattage use by**multiplying the wattage by the hours used daily**:**1000 watts x 0.25 hours = 250 watts/h.****Step 3:**Convert the result to kilowatts:**250 watts/1000 = 0.25 KWh.****Step 4:**To calculate the**daily cost**of using a microwave,**multiply the result by the cost of electricity – 0.25 KW x $0.10 = $0.025 daily.****Step 5:**To calculate the**monthly cost**ofusing a microwave,**multiply the daily cost by 30 days: $0.025 x 30 = $0.75 monthly.****Step 6:**To calculate the**yearly cost**ofusing a microwave,**multiply the monthly cost by 12 months: $0.75 x 12 = $9 yearly.**

Alternatively, you can **multiply the daily cost by 365 days: $0.025 x 365 = $9.125 yearly.**

**It’s a no-brainer!**

Pro tip:

If you’re looking to **conserve energy **or want** your food to heat up quickly, do this…**

When cooking in the microwave, **use a suitable container** and** cover your food**. Additionally, when heating, **rotate your food to ensure even heat distribution. **Also, **avoid opening the door** unnecessarily to shorten cooking times.

## Importance of Finding the Amps and Cost of Running Your Microwave

For starters:

Knowing** your microwave’s amperage** is necessary because it **improves safety** and **protects your appliance from damage**. In essence, **connecting a microwave** to an outlet that supports** lower amperage could damage it.**

Amperage also helps housing planners on **how to allocate power to different rooms** in a house or common space.

And that’s not all:

Learning **how to calculate the cost of running your microwave** helps you manage your** budget**.

If you are particular about how much you spend, your power expense is something you want to pay attention to.

Lastly:

Knowing how much power your microwave consumes can make you more informed about **energy-efficiency decisions**.

Obviously, if you plan to **save money **on your **energy bill**, buying an energy-efficient microwave is critical.

## Conclusion
