0.001 B is not bad for a day , but the ant miner takes huge amounts of current/voltage even though it says it takes only half the amount of the electricity of the other miner's in the market.
Usually for a household here the domestic allowance per household is 3kv.
On normal usage
(Fans,Different kind of lighting, Air conditioner, Washing machine ,Induction,Laptop,Lcd tv ,Mobiles charging,Kitchen appliances, Dvd player)
Takes around 200-450 volts for 2 months.
That is approximately 17 dollars for 2 months.
But the Antminer consumes
The AntMiner S5 consumed 13.88 KWH of electricity for a day of mining.Which is 2795 volts for 24 hours , it's almost 10 times higher than a normal household voltage consumption.
Kwh to Volts converterhttp://www.rapidtables.com/calc/electric/kw-to-volt-calculator.htm
Hashing power 1155 GH/s
Continuous power 578 Watts
Daily usage 13.88 KWH
as per this user reviewhttp://bitcoinrancher.com/bitmain-antminer-s5-power-consumption/
So the power factor is a high consideration but if you say it makes 0.1b In Average run of 24 hours , then it would be able to make 2.5-3 btc a month.
So the Average earning would be 1800 dollars monthly .
With current costs around 75 dollars for 24 hours
which comes around 2250 dollars monthly.
So you gonna make 1800 dollars but how will you pay the current bills then.??
Then probably if you wanna just run it for a week then it's probably ok , but a month uh oh !!!!!!!!!!!!!!!!!!!!
This was a calculation on the basis the antminer makes 0.1B per day , but a user here say's it dosen't
some reviews of the antminer s5http://www.amazon.in/AntMiner-S5-~1155Gh-0-51W-Bitcoin/dp/B00RCTIY4G

I have three of these running along with an S3 and I produce (on average) 0.1 BTC every other day. It's weird... I charge $80 an hour for my tech services but I'm so much more excited over that damned $12 a day that I ever was over what I do for a living
check the amazon reviews
but i don't know in average it might produce 0.001B-0.1B as per a bitcoin talk member and an amazon member review.
These calculations are for 0.1B per day
For 0.001B the miner approximately gives 0.03B with the same power consumption charges, which is even more loss.
