Frequently asked questions
Should I use gross income or take-home income?
For everyday budgeting, take-home income is often the more practical number because it reflects what actually reaches your account.
Why is budgeting useful even if I invest?
A clear budget shows how much money is truly available for savings, investing, and debt repayment each month.
Can I use this for yearly budgeting?
Yes, but monthly budgeting is usually easier to maintain and compare over time.
