Calculating mining cost VS profit

[Vodkanakas]

At idle my pc takes 100w which it use to do that when i wasnt gaming on it. and between work and sleep that it would be idling i want to mine for Sia. So with the miner running im pulling 350. So should i calculate it as 350207/1000 or should i calculate it as 250 seems how that what would be extra from what is my normal usage?

@Vodkanakas at only 350 watts I'd calculate it as 99% profit. I'm not sure you'd even notice an increase in your bill.

@Vodkanakas count everything that you wouldn't be doing normally. I.e. if you let it run at 100W 24/7, then it's only the increase that costs extra.
