Doing things backwards doesn’t often yield desirable results, but there are times when working backwards to solve a problem can be helpful. Budgeting, which is something I’ve never actually done, is one of them. Hence, the backwards budget.
For example, say you finish training at age 32 and your goal is to be FI by age 50. After you’ve spent some time determining how much you need to reach financial independence, you should be able to determine how much you need to save each month to get to that goal.
You should repeat the process from step 1 and 2 as many times as is necessary for your big goals. Say, for example, you had $300,000 in student loans and that you wanted those paid off in five years after training.
