electric cost. am i calculating this correctly? seems high

hey everyone.

i'm trying to guesstimate how much i can expect my electric bill to go up this month now that I'm starting using HID and a more power consuming setup.

I'm running

-400w mh/hps cool tube = about 475 (ballast draws more than 400 from what i've heard)
-4 inch inline fan = 115w
-portable ac = 515w

= 1100 or so total watts

if my rate is .13 kw/hr and you say I'm running 1100 total watts around the clock, which, hopefully i won't need to do that with the AC but i'm trying to achieve a worst case scenario figure, and also I'm running 20/4 light cycle for 2 more weeks when before hitting 12/12, then you multiply .12 cents by 1.1 since that is how many kw/hr i'd be using, correct? that comes out to like $3.12 per day then multiplied by 30 which is like NINETY bucks extra a month for this.. is this right? i hope i'm wrong but something tells me that I'm not

Hi mate

yep that seems right. Man I wish my set up cost me 90$ a month I pay around 200 per month for my power

Check out the Spreadsheet the dude made. it works great. super easy to figure this shit out.

sweet spreadsheet

Nice Sheet. Any time saved can go into growing/smoking/cooking.

eh okay. i figured that would be the response. hopefully when i go 12 /12 it isn't so bad since I'm cutting the lights runnig time in half and while the light is off i should be able to run the AC at a pretty easy clip. thanks for the responses, everyone. all info is appreciated
