Your net income is what you take home after income taxes and other deductions are made. This is different from gross income, which reflects your income before any deductions.

It's important to remember that net income can be either positive or negative. In the former, it means profit, while in the second, it's prejudice or loss.

Calculating Net Income

To calculate your net income, take your total amount of money earned (gross income) and subtract all payroll deductions.

So, the formula for net income is quite straightforward:

Total Earnings - Payroll Deductions = Net Income

If you have other sources of income, like investments or Social Security, you can add this to your net income.

Tax Returns and Net Income

In the U.S., taxpayers report their annual earnings to the IRS by submitting Form 1040.

The form itself doesn't have a line for net income but there is room to report adjusted gross income as well as your taxable income. Most pay stubs will also have a dedicated line for net income.

Net Income for Business

To calculate net income for business, subtract total expenses from total revenue. This gives the amount left after all bills and expenses, like business loans, are paid.

The net income formula for a business is:

Revenue - Cost of Goods Sold - Expenses = Net Income

Sometimes it can be helpful to break this down by category to get a more detailed picture of where the profits are coming from.

Here is an example of net income:

Comfort Shoes has a total revenue of $60,000 and they want to find their net income. Their expenses are as follows:

  • Rent: $5,000

  • Cost of goods sold: $15,000

  • Utilities: $1,000

  • Advertising: $500

  • Payroll: $12,000

  • Interest expense: $1,000

So to calculate the net income, we take:

$60,000 (gross income) - $15,000 (COGS) - $19,500 (expenses) = $25,500.

Net Income and Loan Qualification

When applying for a loan, many people focus on their credit score, but your net income can be equally crucial in the approval process. Some lenders can primarily use your net income to determine your loan eligibility.

To strengthen your loan application, properly document your net income with:

  1. Pay stubs: Provide your most recent 2-3 pay stubs showing consistent income
  2. Bank statements: Submit 2-3 months of statements showing regular deposits
  3. Tax returns: Include the last 1-2 years of tax returns, especially if self-employed
  4. W-2 forms or 1099s: These verify your reported income from the previous year

Debt-to-Income (DTI) Ratio and Your Net Income

Your debt-to-income (DTI) ratio is one of the most critical metrics lenders use when evaluating loan applications. This ratio compares your monthly debt payments to your monthly net income, expressed as a percentage.

How DTI Is Calculated

DTI is calculated using this formula:

DTI = (Total Monthly Debt Payments ÷ Monthly Net Income) × 100

For example, if your monthly net income is $5,000 and your total monthly debt payments are $2,000, your DTI would be:

($2,000 ÷ $5,000) × 100 = 40%

Lenders typically consider two types of DTI:

  1. Front-end DTI: Only includes housing-related expenses (mortgage/rent, property taxes, insurance)
  2. Back-end DTI: Includes all debt payments (housing, car loans, student loans, credit cards, etc.)

Improving Net Income

If you need a better net income, either for you long-term personal finances or for a loan, we have some tips for you.

Short-Term Strategies

  1. Adjust tax withholdings: If you typically receive large tax refunds, consider adjusting your W-4 to have less tax withheld from each paycheck. This increases your monthly net income, though you should ensure you won't owe taxes later.
  2. Request a salary review: If you haven't received a raise recently, prepare documentation of your contributions and request a compensation review. Even a 3-5% increase can significantly impact loan qualification.
  3. Pick up overtime or extra shifts: Temporary increases in work hours can boost your net income. Many lenders will consider consistent overtime pay if it's been received for at least 6 months.
  4. Reduce retirement contributions temporarily: While not ideal for long-term financial health, temporarily reducing 401(k) or other retirement contributions can increase your net income during the loan application process.

Long-Term Strategies

  1. Develop additional income streams: Side hustles, freelance work, or part-time jobs can significantly boost your income. Lenders typically require at least 1-2 years of history for secondary income sources.
  2. Invest in career advancement: Certifications, additional education, or specialized training can lead to promotions or higher-paying positions.
  3. Start a small business: Even a part-time business can generate additional income. Keep good records, as lenders will typically want to see 2+ years of business tax returns.
  4. Monetize existing assets: Consider renting out a spare room, participating in car-sharing programs, or generating passive income from investments.
