How much does a part-time tester cost?

Question

Android

They offered to earn some money and periodically test the fixes that the developer makes to the mobile application. I myself work as a developer for Android and I know all this kitchen, but I haven’t had to work as a tester yet. Is it worth it if there is a general understanding of the testing process, but I don’t understand all the terms of testing (although I understand what it is about and there is Google). I will also add that the project there is not big and people need manual testing of small features that appear over time, i.e. there is no talk of any large production. And the second question: how much does such work cost?

Answer 1

Your average monthly salary at your main job, divided by 30 and another 24.
Get the price of your dirty hour of work. Multiply it by two for freelancing/one-off jobs.
This is common practice.

Answer 2

divide by 20 and not by 30
if you want to rest 2 times a week =)
and not by 24 hours
but by as much as you work per day
for example 7 or 8
suppose you get 32000 per month You work
20 days a week and 8 hours a day
it will turn out 32000/20/8
This is the cost of your labor 1 hour
