I'm afraid that without factoring future increases in difficulty, this is fairly useless.

Hi everybody!

I created an online calculator to estimate mining profitability.

Please check it out at http://bitcoinx.com/profit/

It is still in beta phase so be careful with the results. I am open for suggestions / additional features.


If you are interested, these are the main calculation formula:

    $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));
