Understanding Your Income
Before you can manage your money, you need to know exactly how much you have coming in. But here's the thing: the number on your job offer isn't the number that hits your bank account.
Gross vs. Net Income
Gross income is what you earn before anything is taken out. Net income (also called "take-home pay") is what you actually receive after taxes, insurance, and other deductions.
You can only spend what you actually receive — so always budget with your net income.

What You Actually Receive
Gross monthly: $3,750

Minus 401(k) (5%): -$188
NET TAKE-HOME: $2,587/month
That's $1,163 less than the gross amount!
