Title: Formula to figure out BTC Per Day?
Post by: blizz3010 on May 04, 2014, 05:25:34 PM
Anyone know the formula to figure out BTC per day? Been working on coding again and making an app for myself and havent seemed to locate it anywhere yet. Figured someone here might know it off hand.

Thanks.

Code:
The average amount of time (in seconds) to find a single share is:

difficulty * 2^32 / hashrate
In that equation, difficulty is the difficulty of a share and hashrate is your hash rate in hashes per second. A day has 86,400 seconds in it, so the number of shares you'll find in 24 hours is:

86,400 / (difficulty * 2^32 / hashrate)
A slightly more complex formula, using PHP:

$hashTime = ((float) $difficulty) * (pow(2.0, 32) / ($hashRate * 1000.0)) ;
$powerCostPerYear = 365.25 * 24.0 * $powerConsumption / 1000.0 * $electricityRate;
$blocksPerYear =  (365.25 * 24.0 * 3600.0) / $hashTime ;
$coinsPerYear = $blockCoins * $blocksPerYear;
$revenuePerYear = $coinsPerYear * $conversionRate;
$profitPerYear = $revenuePerYear - $powerCostPerYear;
$netProfit1st = $revenuePerYear - $costHardware - $powerCostPerYear;
if ($profitPerYear <= 0) $breakEvenTime = -1;
else $breakEvenTime = $costHardware / ($profitPerYear / (365.25 * 24.0 * 3600.0));
