The Litecoin mining calculator helps you estimate how a Scrypt ASIC performs under a specific LTC price, pool fee and electricity tariff.
It is useful when several pools look similar at first glance, because even a small fee difference can change the net result over time.
You can adjust the hashrate, power draw and number of devices to match your own hardware instead of relying on a generic preset.
For a realistic view, test several scenarios with different LTC prices and electricity costs before choosing a pool or buying hardware.
