On this page, you will find out how many watts a table saw draws.

Got a big job ahead of you? Then you need to ensure the workhorse of your workshop is running smoothly. The ability to properly crosscut and rip is going to make your work a lot easier. One thing you need to understand is that table and bench saws are large pieces of equipment that guzzle a lot of power when in operation.

Below we will discuss and test table saw wattage, explain how to work it out for yourself, and calculate the total electricity required.

How Many Watts is a Table Saw?

The average table saw uses between 1500 and 2000 watts.

The exact number depends on the size and model of your table saw. Generally, you will find that the larger the equipment the more power it will draw. Adding to this saws that run at over 2000W can cut at a slightly higher depth, include soft start induction motors, and stronger dust extraction.

The wattage can vary by about 500W between the largest and smallest machines. Cutting depths tend to rise and fall with the power rating. You will notice that appliances rated 1500W or lower will only cut upto 3 inches (80mm) while larger saws can cut thicker materials.

How to Find Out Your Table Saw Wattage

There’s 3 ways you can work out the wattage of a table saw.

  1. Check Product Specification

The quickest way is to look at the table saw’s specification. The watts (W) is usually written on a sticker on the base of the appliance. If not, you can check the user manual or the manufacturer’s website for technical details.

  1. Use a Wattmeter

A wattmeter is brilliant for getting a live wattage reading and tracking total energy usage of any appliance. You can simply plug it into your table saw to get instant information. 

I used one to test my table saw which gave a live reading of xxxW.

  1. Wattage Formula or Calculator

If you know the amperage and voltage of your table saw you can use this to find the maximum watt rating. Simply use the formula Amps x Volts = Watts. Or you can head over to the ‘Watt Calculator’ to work this out.

Table Saw Wattage Examples

Let’s take a look at specific examples of how many watts a table saw draws. Below is a collection of modern table saws with their listed power ratings.

DEWALT DWE74851850
BOSCH GTS 635-2161600

As you can see, the power ratings vary between different table saws. So you should take the time to check your own appliance.

How Much Electricity Does a Table Saw Use?

You can use table saw wattage to work out how much electricity it uses. Plus this can be useful in understanding how much it costs to run your table saw.

A watt (W) is a measurement of power at a single point in time. A watt-hour (Wh) is the total amount of electricity used in an hour. For example, a table saw drawing 2000W would use 2000Wh when running for an hour.

Happily, electricity bills are recorded in kilowatt-hours (kWh). A kilowatt is simply 1000 watts. So a 2000W table saw running for 1 hour uses 2kWh.

Let’s say you actively run your table saw for 10 minutes a week. This means a table saw uses about 333Wh or 0.333kWh electricity a week That’s 1.431kWh a month and 17.182kWh a year. 

That’s an electricity cost of $0.21 a month or $2.57 a year to cut with your bench saw for 10 minutes a week.

In reality, these numbers vary from person to person. DIY users might run for a lot less than this, while professionals can be much higher.

Using a Table Saw Off-Grid

If you’re planning to use your bench saw in an off-grid situation like a remote location or power outage the information above is crucial. You need to know the wattage to select the correct electrical equipment and know the runtime.

You can either use a power inverter, portable power station, or generator to generate AC electricity. 

To make sure everything runs smoothly you should check two things on this equipment – wattage capacity and total energy capacity. 

Your power source, like an inverter, should have a wattage capacity of at least 20% more than your table saw. This ensures it will be able to deliver enough power as they are never 100% efficient. To use your cutting tool, it is best to have 2500W power capacity. This will be enough to run most appliances and cope with startup surges.

Secondly, you need to ensure your energy source, like a battery, has enough energy to run the table saw for the required amount of time. As we already know, it will use about 333Wh electricity for 10 minutes. This is the equivalent to 27.75Ah on a 12V battery.

How Many Watts Does a Table Saw Use Summary

I hope you have learned how many watts a table saw uses.

Tools like these bench saws use a lot of power. The largest options can reach over 2000W from an induction AC motor. This means you’re going to need a serious inverter if you’re planning to run off-grid. The total electricity usage will be specific to your work. Most casual DIY users won’t rack up a huge cost but professionals should expect a noticeable difference in electricity usage when running for long periods.
