Budgeting is the first step to managing your money. Followed by tracking your expenses and readjusting your budget until it fits your needs and wants. It took about 6 months before I was able to feel comfortable with my budget allocations for each of the line items on my budget.
The short answer is it’s based on your financial goals, needs and wants. There is no right allocation as much as there is no right way to save and spend your money. There are only suggested guidelines based on statistical data and empirical research.
