This calculator is designed to help you see how profitable Ethereum mining can be for you. Input your information, such as hashing power/hash rate and any pool fees you may have. If you're using your own mining rig, input your hardware costs, power usage and power price, in kw per hour (you can find this on your electricity bill, or search online for state averages if you're unsure). Then hit calculate.
The estimated result is based on the current ETH to USD price, as well as the mining difficulty. There are results for daily, weekly, monthly and yearly profits, as well as how much time, in days, it will take to break even on either your contract price or the cost of your rig.
