How do I figure out my personal net income?

To calculate your personal net income, start by determining your total income, which includes wages, bonuses, investment earnings, and any other sources. Next, subtract your total expenses, including taxes, insurance, and living costs. The result is your net income, which represents your take-home pay after all deductions. If you want a clearer picture, consider tracking your income and expenses over a few months to account for variability.
