The problem with mining calculators with pre-installed coins is that in order to calculate the profitability of a new coin, the creator of the calculator must add that coin. This may take several days for the creator of the calculator due to lack of knowledge about the new coin or lack of time. Therefore, there is nothing better than a table in Excel. Knowing the block time, block reward, network hashrate and the hashrate of your rigs/asics, you can independently and quickly calculate the profitability of any new coin.
