Understanding Gross vs. Net Income

When you receive a job offer or a salary increase, the figure quoted is almost always the Gross Income. This is the total amount of money earned before any taxes or mandatory deductions are removed. However, the amount that actually lands in your bank account is your Net Income, often referred to as "take-home pay."

Common Deductions Explained

• Federal/State Income Tax: Percentages of your income that go to the government to fund public services.
• Social Security (FICA): A mandatory payroll tax that funds retirement and disability benefits.
• Medicare: Tax used to fund the federal health insurance program for people 65 and older.
• Health Insurance Premiums: If you have an employer-sponsored plan, your share is typically deducted directly from your gross pay.
• Retirement Contributions: Contributions to plans like a 401(k) or 403(b) are usually deducted before you see your paycheck.

Calculation Example

Imagine your monthly gross salary is $4,000. Your estimated total tax rate is 15% and your other deductions (Social Security and Insurance) total 7%.

1. Tax Deduction: $4,000 x 0.15 = $600
2. Other Deductions: $4,000 x 0.07 = $280
3. Total Deductions: $600 + $280 = $880
4. Net Monthly Income: $4,000 – $880 = $3,120

Why This Matters

Calculating your net income is essential for accurate budgeting. Using your gross income to plan your rent, car payments, or savings goals can lead to financial strain, as you may be overestimating your actual spending power by 20% to 30%.
