How many GHs do you need to break even if you got a miner now?

[The Goat Master]

If I got a miner, delivered right now, how many GH's would I need to possibly break even, accounting for the ever-increasing difficulty?

how much are you spending

0.0000001 GH/s.

You'd immediately start making a profit if you're getting free mining hashpower and have zero electric costs.

Good point, haha.    But if I had to actually spend money, how many gigahashes?

[dwdoc]

You probably need at least 1 GH/sec per $40 spent if you start mining right now to break even.

[lemonte]

All depends on how much money you are spending, what equipment you are buying and how much your overheads are.

We can't just pull a figure out of thin air, for all we know you could have got the deal of the century, or could have paid over the odds for a block erupter.

I really hope bitcoin reaches $200 quick so I can get equipment in the bitcoin store for half price!

The number of GH/s is irrelevant what matters is the cost per GH/s.

Spot on!

[bbxx]

decent price of GH/s for ASIC in hand is 0.3 BTC

if you overpayied you will not get your BTC back

Spot on!

And unless you're getting free power, the power consumption per GH/s. On the low end a 30-40w upgraded Jalapeno running at 8GH/s is going to stay relevant longer than 24 USB block erupters. Some of the analyses I've seen which round the power consumption of several competing products to a single value are a bit suspect.

86GH/s at 30 btc max cost

What is the current network hashrate?

At current difficulty you'll need about 350.

[Amph]

now you need 112 at 30 btc

it's easy, GH/s= difficulty digits before the first point
cost always 30 btc max(about 3 months roi)

 Most reasonable answer here was

 Per 1gh/s you could spend 40$ or less , it can be 100 gb for 4000 dollars all we care , but that reach is break even , anything else profitable.

an answer here:

http://laurent.henocque.com/post/2013/09/16/On-Bitcoin-Mining-and-the-vallue-of-Bitcoin

at current mtgox price 139$, you should not pay now more than
16 dollars/GH if you expect mid october delivery
11 dollars/GH if you expect early november delivery
8 dollars/GH if you expect mid november delivery
6 dollars/GH if you expect early december delivery
4 dollars/GH if you expect mid december delivery
3 dollars/GH if you expect early january 2014 delivery

this is for raw break even. If you want to be on the safe side, these figures should be divided by four (one month delay, plus targetting to double your BTC)

or the value of a BTC should be multiplied by 4.

Terahashes will be the new Gigahashes fairly soon.

If bitcoin value doubles, then so does the market price per GH, all other things being equal.
So nope, aint gonna happen.
