Why you should trust this review
We have tested over 20 circular saws in the sub-$100 price range across three years. We evaluate budget saws by the standards of their intended users: weekend DIYers, first-time homeowners, and occasional renovators rather than professional contractors. Our test materials reflect realistic beginner projects: pine 2x4 framing, 3/4-inch plywood, and 1-inch hardwood boards.
How we tested budget circular saws
Each saw completed 30 crosscuts and 20 rip cuts in our standardized materials. We checked cut squareness with a precision square and evaluated edge smoothness by touch. We then ran each saw at full load for 15 consecutive cuts to check for thermal protection activation and measured blade coast-down time as a safety indicator.
Who should buy a budget circular saw?
Homeowners tackling their first deck build, fence repair, or room renovation. Apartment dwellers who need a saw for an occasional project but cannot justify a $150 or $200 tool that will sit unused most of the year. Woodworking beginners who want to learn cutting technique before upgrading to a premium tool.
DEWALT DWE575SB: the best circular saw under $100
The DWE575SB’s 15A motor is the first thing that distinguishes it from lower-priced alternatives. Most truly budget saws at $55 to $70 use 13A motors that bog noticeably in dense lumber. The DEWALT maintained full cutting speed through every 2x10 lumber cut in our test without any hesitation. The electric brake is a safety feature normally reserved for higher-priced saws, and its presence makes a meaningful difference in how quickly the saw is safe to set down after cutting.
At its frequent sale price of $89 to $99, the DEWALT is the most rational sub-$100 purchase. Its construction and components are identical to what you would find in a $130 saw from a lesser brand.
SKIL 5280-01: the best truly budget option
If the DEWALT is not on sale and the price gap is significant, the SKIL 5280-01 at $69 is the best true budget alternative. Its 15A motor matches the DEWALT’s power spec, and the saw produces accurate cuts with the included 24-tooth carbide blade. The coast-down without an electric brake is the main safety compromise. For occasional users who are careful about setting the saw down before blade stop, it is an acceptable tradeoff.
What to look for in a budget circular saw
Amperage. This is the most important spec at any price point. A 15A motor in a budget saw will outperform a 13A motor in a slightly higher-priced competitor. Check amperage before comparing prices.
Electric brake vs. coast-down. Electric brakes are standard on DEWALT at this price. Coast-down saws keep the blade spinning for 10 or more seconds after release. For frequent use, an electric brake is the safer and more convenient option.
Sightline design. A saw with a clear sightline to the blade-pencil mark junction is easier to cut accurately, especially for beginners. Check user reviews specifically mentioning sightline quality.
Bevel range. Most budget saws offer 45-degree bevel. Some reach 52 to 57 degrees. The extra range matters for specific compound cut applications. For most standard projects, 45 degrees is sufficient.
Frequently asked questions
Can a $100 circular saw handle framing work?+
Yes, 15A saws at this price point handle standard framing lumber comfortably. They lack the magnesium shoe and worm-drive torque of premium saws but perform adequately for most homeowner framing tasks.
What is an electric brake on a circular saw?+
An electric brake reverses current flow briefly to stop the blade within 2 seconds of trigger release, instead of the 10 to 15 second coast-down of standard saws. This is a meaningful safety feature for frequent use.
What blade should I buy for a budget circular saw?+
A 40-tooth carbide-tipped blade suits most general cutting. For a budget saw, invest in a quality blade: a $20 carbide blade significantly improves cut quality over the included stock blade.
Is the DEWALT DWE575SB suitable for a beginner?+
Yes, the clear sightline, dust blower, and electric brake make it more beginner-friendly than many alternatives. The 15A power means less need to force cuts, which is safer for new users.
