How much is a MegaHash/s worth?

[stakhanov]

Is there a website or service that computes how much a megahash/s will earn you daily on average, taking into account the current difficulty?

Thanks!

Could you do this for a longer timeframe too? Something along the lines of "since January"...

Also: On which data is this based on?

Probably the difficulty and the spot price

I started to collect data maybe 2 weeks ago. I will be adding new graphs soon.

Current difficulty is parsed from block explorer http://blockexplorer.com/q/getdifficulty, USD weighted price is taken from bitcoin charts (based on mtgox) http://bitcoincharts.com/about/markets-api/ and conversion to EUR is done with google calculator api.

This is what Keefe posted somewhere in the forums (historic data):

If you know how to use R:

Code:

coins.currentdiff<-function(days,hashrate)
	{
	block.val<-50
	current.difficulty<-scan(url("http://blockexplorer.com/q/getdifficulty"))
	(block.val*10^6*days*24*3600*hashrate)/((current.difficulty)*2^32)
	}

if not, amount of coins from a given rate of Mhps:

Code:

block value * 10^6 * hashrate (mhps) /(current difficulty*2^32)

In the case of 1 Mhps and 1 second (ie 1 Mhash), and current difficulty and block value:

Code:

52 * 10^6 * 1/(434882.7*2^32) = 2.676936e-08 coins.

This will of course change as difficulty and block value change, and keep in mind these are average expected values. Also there is a history of difficulty somewhere, but i can't find linky.

Hope this helps.
