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.

All us SoCal. consumers get to look forward to a  20%-40% rate hike next year. Yippee! 

Thanks,  Southern California Edison.
 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


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.
