I Unplugged My Microwave After Every Use for Two Weeks to See If It Would Lower My Electric Bill Here’s What I Learned

With electricity prices continuing to rise, I’ve been looking for simple ways to reduce my monthly energy costs. Like many people, I had heard that appliances continue using electricity even when they’re turned off, thanks to something known as “phantom power.” Curious to see if that tiny amount of wasted energy really mattered, I decided to run a small experiment.

For two weeks in April, I unplugged my microwave every single time I finished using it. It seemed like a simple enough habit, but I wanted to know one thing: would it actually save enough electricity to make a difference on my utility bill?

Here’s exactly what happened.

Why I Chose the Microwave

Most of us never think twice about leaving a microwave plugged in all day. Even when it’s not heating food, the digital clock remains on, meaning the appliance is still drawing a small amount of electricity.

According to energy experts, this is called standby power or phantom load. While each device only consumes a little electricity, every appliance in a home contributes to the total.

The U.S. Department of Energy estimates that standby power can account for 5% to 10% of a household’s electricity use, so I wanted to find out whether eliminating just one phantom load would produce noticeable savings.

How I Measured Everything

To make the experiment as accurate as possible, I used a plug-in electricity monitor to measure exactly how much power my microwave consumed while sitting idle.

I also tracked my household electricity usage through my utility company’s online dashboard and compared it with previous billing periods to see whether unplugging the microwave had any measurable impact.

Throughout the two weeks, I carefully recorded the numbers and kept my normal household routine unchanged.

How Much Electricity Was the Microwave Actually Using?

The monitor confirmed that my microwave consumed roughly 3 watts whenever it sat plugged in but wasn’t being used.

Three watts doesn’t sound like much, but over an entire year that adds up to approximately 26 kilowatt-hours (kWh) of electricity.

Seeing those numbers was surprising. It reminded me that many other electronics around the house are quietly doing the same thing every hour of every day.

Still, compared with major appliances like refrigerators, air conditioners, or electric water heaters, the microwave’s standby consumption is relatively small.

Did My Electric Bill Change?

After completing the two-week test, I compared my energy usage with previous weeks.

The result?

My microwave used about 0.5 kWh less electricity during the experiment.

At my local electricity rate of approximately 12 cents per kWh, that translated into savings of only a few cents over two weeks.

Technically, I saved money—but the difference was so small that it would easily disappear among the normal daily fluctuations of household energy use.

What Would the Savings Be Over an Entire Year?

If I continued unplugging my microwave every day for a full year, I’d save approximately 26 kWh of electricity.

At my electricity rate, that’s roughly $3.12 annually.

While every dollar counts, three dollars a year isn’t exactly life-changing.

It became clear that unplugging one microwave isn’t going to dramatically reduce anyone’s electric bill.

The Part I Didn’t Expect

The biggest surprise wasn’t the savings—it was the inconvenience.

Every time I plugged the microwave back in, the clock reset to 12:00.

I either had to live with a flashing display or spend time resetting the clock several times each day.

My outlet is also tucked behind other kitchen appliances, so reaching it meant constantly moving things around just to unplug and reconnect the microwave.

After only a few days, what sounded like a simple habit became surprisingly annoying.

Is Constantly Unplugging an Appliance Safe?

While microwaves are designed to be plugged in and unplugged safely, repeatedly pulling the cord from the outlet every day can eventually create wear on both the plug and the receptacle.

Loose outlets, damaged cords, or improperly inserted plugs can create safety concerns over time.

Many energy professionals recommend using a switched power strip instead. With a simple flip of a switch, you can completely disconnect power without repeatedly handling the plug itself.

What Energy Experts Recommend Instead

Most energy experts agree that reducing standby power is worthwhile—but they also point out that your efforts are better spent targeting larger sources of electricity use.

Instead of focusing on a microwave, you’ll usually save much more money by:

• Replacing old incandescent bulbs with LED lighting.
• Adjusting your thermostat by a few degrees.
• Upgrading older appliances to energy-efficient models.
• Using smart power strips that automatically shut off idle electronics.
• Running dishwashers and washing machines during off-peak hours when available.

These changes typically produce much greater savings than unplugging a single kitchen appliance.

When Unplugging Actually Makes Sense

Disconnecting appliances can still be worthwhile in certain situations.

Devices that sit unused for weeks or months—such as guest-room televisions, gaming consoles, printers, or stereo systems—can waste electricity year-round without providing any benefit.

For appliances you use multiple times every day, however, the inconvenience often outweighs the financial reward.

My Final Verdict

After two weeks, I learned that unplugging my microwave does reduce electricity use—but only by a very small amount.

The annual savings simply aren’t significant enough for me to continue doing it every day.

Instead, I’ll focus on habits that provide bigger returns, such as improving lighting efficiency, managing heating and cooling more carefully, and using smart power strips where they make sense.

Although this experiment didn’t dramatically lower my electric bill, it did change how I think about energy use around my home. Even small habits can increase awareness, and when combined with other energy-saving strategies, they can contribute to lower costs and a more energy-efficient household.
