Well, this is all empirical but the main thing I take into account is Time. Like, if there is any new tech I need to learn, usually it&#x27;s added into how much time I would spend building the app itself. Then I dig into the complexity of the app. I accumulate these in points and put into a scale of my hourly rate. For example, the highest I charged anyone for a very difficult project is 150&#x2F;hr which I rate at a 10, the lowest for a simple project is 85&#x2F;hr.<p>I add the factors together and see where it rates out of 10 then make the final price per hour.<p>I like being straight forward, so I use Trello for task management, Github for version control &amp; Slack for communication between me &amp; the client.<p>Hope this helps!!!
