I know there are many calculators but I want to be sure they tell me the right numbers.
ZEC
Network hashrate: ~22 000 000 Sol/s
Your hashrate: 1000 Sol/s
Miner reward: 6.23 (current)
Blocks per day: 570
Your ZEC amount: 570 * 6.23 * 1000 / 22000000 = ~0.1614
Price: 0.1041 BTC per ZEC
In BTC: 0.1614 * 0.1041 = 0.0168 BTC per day.
In $: 0.0168 * 750$ = 12.6$
Power
Consumption: 0.800 kWh (for example, rx 470 4GB 1260/1850, 1.05V - about 135 Watt, 1160/1850, 0.95V - about 105 Watt per card)
Price: 0.05$ per kW
Day cost: 0.800 * 24 * 0.05 = 0.96$
Total
12.6 - 0.96 = 11.64 $ per day
