Net Income

Net income is the amount of earnings left after all required and elected deductions are subtracted from gross income. For an employee, that means gross pay minus income tax withholding, payroll taxes, and any benefit deductions such as health premiums or 401(k) contributions — the figure commonly called take-home pay. In a business context, net income is the profit remaining after every expense, including taxes, has been paid.

Net income wears two hats. For an individual it is take-home income, what remains of earnings after taxes and deductions, and for an employee that is the same figure a paycheck calls net pay. The layer-by-layer paycheck breakdown that produces it, income tax withholding, FICA, and pre-tax and after-tax deductions, is the subject of the net pay page; this page treats net income as the broader financial concept and, for a business, as the profit that remains after every expense.

Then come the deductions you choose. Pre-tax items (traditional 401(k) deferrals, health premiums, HSA and FSA contributions) reduce the income your withholding is calculated on, so they cost you less than their face amount. That creates a subtle trap when judging your finances by take-home pay alone: someone saving aggressively in a 401(k) has a lower net income but a stronger financial position. Net income also differs from taxable income (the figure your tax bill is actually computed on, after deductions), and from adjusted gross income — three different numbers that get conflated constantly.

Start with gross pay, subtract pre-tax deductions, then payroll taxes, then income tax withholding, then any after-tax deductions. What's left is net income.

A hypothetical example: Jordan earns $80,000 a year, or about $6,667 per month gross. Each month, $300 goes to a pre-tax health premium and $400 (6%) to a traditional 401(k). FICA taxes of roughly $487 come out (7.65% of the FICA-taxable wages), and combined federal and state income tax withholding runs about $880 based on Jordan's W-4. Net income: $6,667 − $300 − $400 − $487 − $880 = about $4,600 per month. The withholding figures here are illustrative: actual amounts depend on your W-4 entries, state, and filing situation.

Pros (of budgeting from net income)

• It reflects money you can actually spend, so your budget matches reality.
• It forces you to see the true cost of taxes and benefits rather than mentally spending your gross salary.
• It updates automatically when your withholding or benefits change.

Cons

• It understates your total savings effort — pre-tax 401(k), and HSA contributions are savings, even though they never hit your bank account.
• Withholding is only an estimate; if your W-4 is set wrong, your "net income" is quietly borrowing from (or lending to) the IRS until you file.
• Comparing net income across jobs can mislead, since benefit costs and state taxes differ.
