How do you set/calculate the cost of tariffs for your own web/mobile projects/applications?

Let's say you release an app and set it up for subscription access.
How do you set/calculate the cost of tariffs?
For example, you take into account the costs of maintaining the application (servers), the work of the team (office, salary), and so on ... In addition, you spent some time and resources on development. In this matter, I would not like to focus on competitive applications and my own greed, but to collect the maximum of aspects for which it would be possible to make a miscalculation of the base cost, and only then develop a tariff line and a system of discounts.
For example, you told yourself that you want to receive a salary of 100,000, then you take all current expenses, part of the expenses for the development of the application, part for operational activities and development, advertising, etc. , add your salary and remuneration to third parties and divide by the number of potential subscribers? But this would be too easy a scheme, if it were not for the fact that at first there may be very few such subscribers and it is dangerous to set a high cost, you can scare off users. At the same time, I would not want to make a low cost, and then sharply increase it, since it is ugly.

For example, cloud storages from Yandex, Google and Microsoft vary greatly in tariffs for the same volume provided, in fact they offer the same service, and each of them has its own user. How do they understand that this is the price in the base rate should be?

It's called building a business model, I can't explain it in a nutshell... In general, you're right, the payback period is taken, all costs are considered, divided by the predicted number of subscribers and the price is obtained. But you need to take into account competitors, and the presence of a loyal audience (the same clouds are usually sold as an additional service, and even non-obvious bonuses like Office 365 from MS), and much more.
