Profit is calculated via the deduction of expenses from income.
The income consists of daily payouts which size depends on the hashrate. In order to calculate an estimated income using the hashrate you will need to include it in one of the calculators below:
2. Litecoin (set all Power values to zero)
4. DASH (set all Power values to zero)
Next, deduct the maintenance + electricity fee of 0.004 USD per 10 GH/s of SHA-256 and 0.01 USD per 1 MH/s of Scrypt from the income. ETHASH and X11 contracts are not subject to any fees.
The sum you end up with is your estimated profit.
