Cost to keep equipment running / on


I know I could probably figure this out with a little math but wondering if anyone has already done the work.  I'm wondering how much it's costing me to leave my equipment running.  Here is the main equipment that I'm leaving on 24 hours / day.

2 SVS SB subbwoofers (not on standby, always on)
Marantz av7500 processor
Anthem PVA7 7 channel amp
2 PS Audio M700 amps

I figure the subs might be pulling alot of juice even when not in use and probably the Anthem PVA7 amp as it's class A/B I believe.

I'm in the Dallas area and I'm paying about 12.5c per kwh I believe.  

Just looking for ballpark numbers as my bill is definitely higher than I feel it should be.

Yeah, mine is definitely higher than I feel it should be too. And not just electricity. You should see my property taxes! 
It don’ require any steekin’ math.

How do you expect to be "in the ballpark" without measuring?
Uh, it's called estimating.
Uh. Then give him the genius estimate.
Yes you're that good

It’s easy enough just to measure as fuzztone suggested. My equipment consume around 180watt whether playing or not (all class A).
Keep the bigger picture in mind while computing the cost of your gear's energy uses:

@hilde45 thanks for the site. Yeah none of those are sucking that much energy.  I guess mine is all the AC then.  

Yes i know it's "easy enough" to get the tool to calculate the energy usage but I have better things to do with my time than figuring it out and assuming I'm calculating it all correctly. 

I just wanted a ballpark idea.. It seems like it's not a material issue for anyone on here so I won't worry about it.

Our lives are so complicated, that my strategy has been to mainly consider what my energy company charges for "peak" hours and then get the really big draws on energy (car charger, oven, clothes dryer, dishwasher) timed so as to be off the peak. That is a way of reducing energy costs, not usage, but it is easy to implement and also spares the energy grid.
The Watt Meter Fuzztone posted above will get you exactly how much you're using with anything you plug into it. $15 and it's a great tool you can use all around your house for anything you can think  of. 
Fuzztone, thanks.  Ordered one.  Will be good to know the draw of each component.  The total running electrical cost from my gear, plus the a/c costs of cooling down the heat from from c. 25 tubes, costs me c. $100-150/ mo. In Texas.    Of course, I don’t leave the tube stuff turned on, but the dac stays on. 
Also consider funds toward wife appeasment balance after she find's out about YOUR new stuff.
All us SoCal. consumers get to look forward to a  20%-40% rate hike next year. Yippee! 

Thanks,  Southern California Edison.

Doesn’t sound like you “know”. The tool does not calculate the energy used, it measures it. SMH.

pauly, how do you think numbers get input to the screen.  A calculation from measurements.  It measures, and calculates. Also many of these tools will calculate cost I believe after you input your rate. 

Thanks for that waste of a post.

You are burning as much as a 50 watt bulb at idle. 

If you want cheap electricity support the development of Molten Sodium Reactors.

So, you want one of us to do it for you.
thecarpathian, I figured someone already had a pretty good idea, and that was answered.  Saved $20 too :)
