How to Calculate Net Income

Net income is the amount of money you actually take home after all deductions are subtracted from your gross income. For individuals, that means your paycheck after federal and state taxes, Social Security, Medicare, retirement contributions, and health insurance premiums are pulled out.

For businesses, net income is what remains after subtracting all expenses from total revenue. It's the "bottom line" on an income statement.

Whether you're applying for a personal loan, setting up a budget, or just trying to figure out where your money goes each month, knowing how to calculate net income is one of the most useful financial skills you can have.

The net income formula for individuals is simple:

Gross Income - Total Deductions = Net Income

Your gross income is everything you earn before anything gets taken out. Your deductions include federal income tax, state income tax (if applicable), Social Security tax (6.2%), Medicare tax (1.45%), health insurance premiums, retirement contributions (like 401(k)), and any other payroll deductions.

For businesses, the formula works like this:

Total Revenue - Cost of Goods Sold - Operating Expenses - Interest - Taxes = Net Income

You might also see this written as:

Revenue - Total Expenses = Net Income

Both formulas get you to the same number. The first one just breaks out the expense categories so you can see where the money goes.

Here's how to calculate your personal net income step by step.

Step 1: Find your gross income. Look at your pay stub. Your gross pay is the total amount before deductions. If you earn $75,000 per year, your gross monthly income is $6,250.

Step 2: Add up your deductions. These typically include:

• Federal income tax (based on your tax bracket and filing status)
• State income tax (varies by state, some states have none)
• Social Security tax: 6.2% of gross pay
• Medicare tax: 1.45% of gross pay
• 401(k) or retirement contributions
• Health, dental, and vision insurance premiums

Step 3: Subtract deductions from gross income.

Here's a real-world example for someone earning $75,000 per year ($6,250 monthly gross):

• Federal income tax: $750
• State income tax: $300
• Social Security (6.2%): $388
• Medicare (1.45%): $91
• 401(k) contribution (6%): $375
• Health insurance: $200

Total deductions: $2,104

Monthly net income: $6,250 - $2,104 = $4,146

That's your take-home pay. You can use a paycheck calculator to run the numbers for your specific situation.

Business net income follows a multi-step process. You start with total revenue and subtract costs in layers:

1. Gross Profit = Revenue - Cost of Goods Sold (COGS)

2. Operating Income = Gross Profit - Operating Expenses (rent, payroll, utilities, marketing)

3. Net Income = Operating Income - Interest Expense - Taxes

You'll find net income at the bottom of an income statement, which is why people call it the "bottom line."

Here's a practical example. Comfort Shoes has annual revenue of $60,000. Their expenses break down like this:

Gross profit: $60,000 - $15,000 = $45,000

Operating expenses: $5,000 + $12,000 + $1,000 + $500 = $18,500

Operating income: $45,000 - $18,500 = $26,500

Net income (after $1,000 interest): $26,500 - $1,000 = $25,500

That $25,500 is Comfort Shoes' net income before taxes. To get net income after taxes, you'd subtract their tax liability as well.

These two terms get mixed up constantly, so here's the difference:

Gross income is your total earnings before any deductions. For employees, it's your salary or hourly wages before taxes. For businesses, it's total revenue minus the cost of goods sold.

Net income is what's left after ALL deductions. For employees, it's your take-home pay. For businesses, it's the profit remaining after every expense, including taxes and interest.

Why does this matter? If someone asks your income for a loan application, they usually want your gross income. But when you're planning your budget or figuring out how much rent you can afford, net income is what counts because that's the money actually hitting your bank account.

For example, someone with a $75,000 gross salary might have a net income around $49,752 after deductions. That's a 34% difference, which is significant when you're trying to figure out if you can afford a $300K house or whether your monthly expenses fit your actual paycheck.

Operating income (also called EBIT, or earnings before interest and taxes) measures how much a business earns from its core operations. Net income goes one step further by also accounting for interest payments and taxes.

The relationship is straightforward:

Operating Income - Interest - Taxes = Net Income

Operating income tells you whether a business model works. Net income tells you what the owners actually get to keep. A company can have strong operating income but low net income if it carries heavy debt (high interest payments) or faces a large tax bill.

When you apply for a loan, lenders look at your net income to figure out if you can handle the monthly payments. Some lenders focus on gross income, but many use net income because it reflects what you actually have available to spend.

To strengthen your loan application, have these documents ready:

Your debt-to-income (DTI) ratio is one of the most important numbers lenders check. It compares your monthly debt payments to your monthly income.

DTI = (Total Monthly Debt Payments / Monthly Gross Income) x 100

For example, if your monthly gross income is $6,250 and your total monthly debt payments (car loan, student loans, credit cards, projected new loan payment) add up to $2,000:

($2,000 / $6,250) x 100 = 32% DTI

Most lenders want to see a DTI below 36%, though some personal loan lenders will go up to 43% or even 50% for well-qualified borrowers. For mortgages, the typical maximum is 43%.

Lenders look at two types of DTI:

• Front-end DTI: Only housing costs (mortgage or rent, property taxes, insurance)
• Back-end DTI: All debt payments combined (housing plus car loans, student loans, credit cards, and everything else)

If your net income isn't where you need it to be, whether for a loan application or just better financial breathing room, here are practical ways to boost it.
