calculating expected number of BTC for a mining rig

[flok]

Hi,

Is it possible to somehow calculate the expected number of BTC I would mine for a given hashrate?
I know that my cards do around do around 700MH/s.

average.daily.btc <- your.hashrate / 2^32 / current.difficulty * 50 * 86000

That seems to be the "go-to" calculator, but I really like this one too: http://bitcoinma.appspot.com/

That’s a good one but it fails to include the pool fee so it’s a bit off for those people that pay a fee. 

Many pools don't charge a fee, and taking away the very tiny fee of those which has is trivial. You want to calculate based on HW potential, not for particular pool.

Assuming no mining pool fees, you can use this:

Code:

#!/bin/bash
MHASHESPERSEC="$1"
HASHESPERSEC=`echo 'scale=2;' ${MHASHESPERSEC} '*1000000' | bc`
AVGTOWIN=`wget -q -O - http://blockexplorer.com/q/hashestowin`
AVGSECSTOWIN=`echo ${AVGTOWIN} '/' ${HASHESPERSEC} | bc -l`
AVGHOURSSTOWIN=`echo ${AVGSECSTOWIN} '/' 3600 | bc -l`
echo At $MHASHESPERSEC 'MegaHash/s', the expected BTC gain for 24h is: `echo 'scale=8;' '(50*24) / '${AVGHOURSSTOWIN} | bc -l`

Use it as follows:

Code:

bash ./pps.sh 7000
At [b]7000[/b] MegaHash/s, the expected BTC gain for 24h is: 4.69913750

If the op doesn't notice th extra '0' you snuck in there, he might get a bit excited about what he could earn
