I was looking for a Bitcoin home miner and immediately realized that if you want to keep one running 24/7 you have to be aware of consumption and cost, so I developed this calculator with a few preset miner examples as well as the ability to enter custom values and make simulations.
By playing with it you can visualize the relationship between Hash rate, Power and Efficiency and calculate monthly power consumption and its impact on your electricity bill.
Hope you enjoy. Feedback is welcomed.
