Default Are routers expensive to operate?

I think my router is 12 amps. So 12amp X 120volts = 1440watts. Is that correct? Wow!!
But if I calculated properly I figure that only comes to 18 cents per hour of actual operation.

Boy is someone making a profit on you. We pay $0.08 per kilowatt hour. Québec sells power onto the US grid at $0.02 to $0.04 per kilowatt hour. That's one h_ll of a markup. So, the next time you see a limousine or fancy car, figure you paid for it. How it is that he's driving it and not you?

BTW, you forgot to include building, light, heat, air conditioning, and all of the other stuff that goes into a shop.

SofaSurfer:

I believe you will find that the 12 Amps is peak current, not average running current. You would only use 12 Amps when "pushing" the router hard -- high spin rate with high feed rate through hardwood.

Anyways, to calculate the peak cost, using the 12 Amp peak current and 8 cents per kWh:

12 A x 120 V x 1 h x (1 kW/1000 W) x ($0.08/kWh) = 11.5 cents per hour

Now, as we know, the average current would be much lower (not pushing as hard plus not running the router continuously for the hour.) As a result the cost per hour should be much lower -- I would expect less than a nickel per hour.

I won't get into the issues of real power and reactive power, which would only confuse the isse.

Are they expensive to operate?

Well, first you need another bit that you don't have, thats $18, then you put the dado in the wrong place on that 'perfect' piece of walnut,.... Then the love of your life wants another special project...

Expensive, yep. But worth it!

They are not expensive to operate. It could get expensive to outfit with all the add-ons, & accessories available for them.

Is getting married expensive? Nah. $25.00 for the licence; another $25.00 for the clerk to declare you man and wife. That's $50.00 total. Not bad.

I think the router is similarly priced.

The original reason I posted the question was that I found out it drew 1440 watts. That was quite a shock when you consider that a light bulb is 60 watt and we try to not use them when we don't have to.

I guess the key then is don't use your router when you don't have to. Seriously, for most of us this is a hobby, even more than a hobby and we are in it for the chance to be creative and the value of that is priceless.

If your electric rate is 8 to 12 cents per kwh, running a 60 watt bulb continuously will cost you between 12 and 18 cents per day; between $3.60 and $5.40/month.

Here in Alaska, in the winter, most people leave "security lights" on full time. Over the course of the winter you'd save enough to buy a timer system, but not if you had to hire an electrician to install it. Many still do so, in an effort to be "earth friendly", but it's no great economic savings.

Also, you can do a lot of routing in 1 hour of "router running" time.
