Can somebody please help me what is the exact formula to count ZEC mining profitability?

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

P.S. You can calculate actual miner reward from block number:

Code:

min(12.5, 625e-6 * blockNumber * 0.8)

Wow, thank you very much for the step-by-step answer

I still don't know how the mining difficulty is related to the calculation. Or I don't need to deal with that? It depends on the network hashrate and I need to count only with that?

the diff must be counted if the nethash isn't reflecting it because it has changed before the diff adapted, in fact with that calculation, you may have some wrong result some times, because of this

so for example, if the diff is 1000 and net 1000, but then the nethash change to 900 but diff is still 1000 because the diff retarget is not so fast and in any case is not instant

then you will not earn more because the nethash(900, before was 1000) is lower, but you will end up with the same profit
