How much time should I spend refactoring?

Why is refactoring bad?

If you decide that the changes would have an adequate ROI, you still must make sure that your new architecture doesn’t break existing features and is able to be done iteratively. It’s not an open invitation for the team to rewrite the entire app.
How many copies of code do you need to refactor?
Otherwise you’ll have the classic problem with cloned code: eventually you’ll discover a need to modify code supporting P, and you won’t find all the clones that implement it. Some folks suggest 3 or more copies is the threshold for refactoring.
When is the best time to do refactoring?
The best time to consider refactoring is before adding any updates or new features to existing code. Going back and cleaning up the current code before adding in new programming will not only improve the quality of the product itself, it will make it easier for future developers to build on the original code.
What are the best practices for code refactoring?
The Pull-Up method pulls code parts into a superclass in order to eliminate code duplication. Push-Down takes it from a superclass and moves it down into subclasses. Composing involves streamlining the code in order to reduce duplications. This is done through various processes, including extraction and inline methods.
