Prepare Your Work Area

You should also cover the floor with a drop cloth or plastic sheeting to catch any dust and debris. Don’t forget to protect yourself as well—put on safety glasses and a dust mask to protect your eyes and lungs from dust particles.
Measure and Mark the Center

Set the Compass
Once you know where the center point of the circle is, you can adjust the compass to the desired radius of your circle. Measure from the center point to the outer edge of the circle you want to cut.
Score the Circle
When you’re ready to score the circle and prepare it for deeper cuts, place your compass point at the center mark and gently rotate it to score the drywall's surface. It’s important to ensure that the compass stays upright while scoring.
Extend the Cut Lines

Cut the Circle's Perimeter
With your utility knife, carefully cut along the extended lines, forming the outer edge of the circle. Apply firm but controlled pressure to avoid tearing the drywall.
Create an Access Hole
In the center of the circle, create a small access hole with your utility knife. This will allow you to insert the jigsaw blade.
Cut the Circle with a Jigsaw

You can accomplish this by starting the jigsaw and guiding it along the circular line, following the scored edge. Keep a steady hand and move the jigsaw slowly to maintain a smooth cut. Be cautious as you approach the end of the cut to prevent any splintering or tearing.
Clean Up
Once you are done cutting your circle, turn off the jigsaw and remove it from the access hole. Gently sand the cut edges of the circle with sandpaper to smooth any rough spots.
Patch and Finish

If patching is required, use a joint compound and a putty knife to fill any gaps or seams around the cut circle. To do this, you will need to apply mesh tape to reinforce the seams and let it dry completely. Then, sand the patched area smoothly and repaint it to match the surrounding wall.
DIY vs. Hiring a Pro
Cutting a circle in drywall yourself can cost as little as the price of a jigsaw, utility knife, and other basic tools, which may total around $50 to $100–or less, if you already have them on hand. Hiring a professional drywall installer, however, can cost significantly more, with labor costs ranging from $100 to $300 or more, depending on the complexity of the job.
Additionally, professionals may charge extra for materials and patching or drywall installation, making the DIY approach more cost-effective for simpler cuts. That being said, if you don’t own any of the tools or supplies needed for this project, you could end up spending more to do the work yourself. You should price both options to determine which is more cost-effective for you.
