The high-end microwaves are above 1000 watts. They are the best choice for large families and restaurants. These microwaves ensure fast and efficient cooking by offering many cooking functions that make them worth buying. 

How to find the watts of your microwave?

Typically, the wattage of a microwave is mentioned in its manual, inside the oven door, or on the serial plate on the back of the oven. 

However, if you are unsatisfied and want to find the microwave’s wattage, you can use the time-to-boil method. It will help you to estimate an approximate wattage. 

For instance, if you buy a microwave, the manual indicates that its wattage is 700 watts. You can find out whether it is true or not by putting a cup of water in the oven for boiling. If the water boils in 3 minutes, it is 600-700 watts microwave. 

800-watt microwave will take 2 minutes and 30 seconds to boil the water, and a microwave of more than 1000 watts will take less than 2 minutes to boil a cup of water. 

The boiling time can vary because of different designs and manufacturing brands. 

How much does it cost to run a microwave?

How Many Watts Does A Microwave Use

The microwave ovens consume less wattage compared to conventional and toaster ovens. Therefore, they are not very costly. 

You can use the following formula to find the cost that your microwave needs to run more efficiently than traditional ovens. 


(kilowatt/hours) x (time running) x (cost per kilowatt hour) = cost to run the microwave 

Put the value of the microwave’s wattage, the cost of electricity in your area, and the time of its usage in the above formula; find the price to run the microwave. 

How well does a 1000-watt microwave work? 

A 1000 watts microwave is the best choice for medium to large families because it works exceptionally well and cooks the food evenly within a few minutes without burning it.

Different brands offer different designs and colors in a 1000 watts microwave, so you can choose the one that exactly fits the interior of your kitchen. 

What is input and output microwave wattage? 

Input wattage is the power required by the microwave for display, moving the glass turntable, heating or cooking the food, timer, and power indication. 

The output wattage is defined as the power the microwave uses to perform its functions properly and efficiently. 

According to the experts, input wattage is always greater than output wattage because the power indicates how well and fast the microwave can cook food.
