What formula is used to calculate mining profitability?

Question

Cryptocurrency

Hello!
The task is to write a calculator for cryptocurrency mining.
As I understand it, the calculation requires data on Hash Rate, Difficulty and Block Reward.
And if for the sha256 algorithm I found the calculation formula:

N = (t*R*H)/(D*2^32)
where:
N - income in coins
t - mining period in seconds (for example, a day = 86400)
R - block reward in coins
H - hashrate per second ( for example, 1GHsh = 1000000000)
D - complexity

then for other algorithms (for example: Ethash, Quark, etc.) I cannot find similar formulas. Google has already searched far and wide. I tried to look for calculators implemented in js to draw out the formula - to no avail.
Tell me, please, if not formulas, then at least poke where you can read about them?
Thank you)
