Hello, as much as I search I can not find formulas to calculate myself the profitability of mining these cryptocurrencies: RVN, ERG and ETC. When I try to look for formulas only I come out calculators, anyone could tell me what are the formulas please?

It depends on how much Hashrate the Network have and how big the difficulty is .
To that what kind of mining pool you are using and how much miners there are mining the coin.
Next thing that counts most is what kind of Hashrate you have and how much shares you get and blocks you will find and get.
On top of that what the price of the coin has on the Exchanges and it gets traded.
The best way is to use an calculator like https://whattomine.com/ (https://whattomine.com/)

Yes i know, but i dont need a calculator, i need the formula that use the calculator

I already have written what exactly you need to make a calculation by yourself !
Dont expect that i give you a full written command or something , you should be doing and making a bit more research by yourself.
If you would have tried to use the " search function " here on the forum or on google you would be have found something.
As i have a good day today i guess it should be something that i found .
Try to look around here : Formula to calculate mining profit (https://bitcointalk.org/index.php?topic=3140185.msg32481535#msg32481535)

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

Let's say that whattomine is in my opinion the best calculator to see your profits in mining the parameters are easy i.e. the average daily profit from which the cost of energy is subtracted you can get an idea of ​​which altcoin is more profitable to mine based on your graphics cards

It looks like you like making life so hard for yourself. Lafu actually gave you the answer. You are going to consider a number of factors in your calculations and most of those factor such as the hash rate and difficulty change periodically.

Which means you are going to track the hastrate of a network to the minute you are going to make a calculation.

im doing a website, that needs a table with this type of data, the table refresh itself by 10 in 10 seconds, so i need the formula for calculate in real one parameter in the table

You know now already what you all need to calculate the things , and i guess you have to write your one formular for your Website then.
There are some widgets i found on https://minerstat.com/widgets (https://minerstat.com/widgets) that you can implement easy in your Website if you want.
