Hello, Shuman.

In the PoS algorithm there is no fixed volume of mining produced in one unit of time. In other words, it is not possible to calculate how much you will earn from 100 ATB per day or from 10,000 per month. I'll explain why. The point is that when consensus is reached by the PoS method, the opportunity to participate in the mining is distributed randomly (casually) between all the wallets in the network. No wallet or user can calculate in advance when exactly his/her wallet will be chosen for the mining of new coin. But despite this fact, there is a number of opportunities increasing the amount and chance of new coins being mined, I will list them below:
1. The volume of the stake held on the balance (the more is your share - the greater is the chance of getting mining)
2. The total amount of shares kept in all wallets of all network members (The smaller is the proportion of other network participants - the greater are the chances of getting mining)
3. Complexity at the current stage of mining. With increasing complexity, the volume of mined coins will be reduced. It will happen once in two years. Profitability is reduced by 50%
4. The period of the wallet being online. The more time your wallet is on the network, the greater are the chances of obtaining mining, because only wallets (nodes) supporting the network can participate in the mining (ones that take the information and synchronize with the single distributed registry - the blockchain). Observing all the above recommendations, you can increase your chances of getting mining, however, it is not possible to calculate mining in advance.
