Understanding the difference between your gross pay and net pay is crucial for financial planning. While your offer letter states a gross salary, your bank account tells a different story. Use our Pay Calculator Gross vs Net to estimate your actual take-home pay after federal taxes, state taxes, and deductions like 401(k) and health insurance.
Gross Pay vs. Net Pay: What's the Difference?
The gap between what you earn and what you keep can be surprising. Gross pay is the total amount of money you earn before any taxes or deductions are taken out. This is the number you typically negotiate when accepting a job offer.
Net pay, often called "take-home pay," is the amount that actually hits your bank account. It is calculated by subtracting all mandatory taxes (Federal, State, FICA) and voluntary deductions (retirement, health benefits) from your gross pay.
For example, if you earn a gross salary of $75,000 per year, your net pay might be closer to $55,000 or $60,000 depending on your state and benefits. Knowing this number is essential for creating a realistic budget.
How Taxes Affect Your Paycheck in 2025
Several layers of taxes reduce your gross pay. Our calculator uses the latest 2025 Federal Tax Brackets to provide an accurate estimate.
1. Federal Income Tax
The United States uses a progressive tax system. This means you don't pay a single rate on all your income. Instead, your income is divided into chunks (brackets), and each chunk is taxed at a different rate.
- 10% on income up to $11,925 (Single)
- 12% on income over $11,925 up to $48,475
- 22% on income over $48,475 up to $103,350
- ...and so on, up to 37%.
Before these rates apply, the Standard Deduction ($15,000 for Single filers in 2025) is subtracted from your gross pay to determine your taxable income.
2. FICA Taxes (Social Security & Medicare)
FICA taxes are flat-rate taxes that fund Social Security and Medicare. Unlike income tax, these apply to almost every dollar you earn up to a certain limit.
- Social Security: 6.2% of your gross pay, up to the wage base limit of $176,100 in 2025.
- Medicare: 1.45% of all gross pay, with no limit. High earners (over $200k) pay an Additional Medicare Tax of 0.9%.
3. State and Local Taxes
Depending on where you live, you may also owe state income tax. States like Florida and Texas have 0% income tax, while California and New York have high progressive rates. Our calculator allows you to input an estimated state tax rate to see the impact on your net pay.
Understanding Pre-Tax vs. Post-Tax Deductions
Not all deductions are created equal. Some reduce your taxes, while others come out after taxes. Understanding this distinction is key to using our Pay Calculator effectively.
Pre-Tax Deductions
These are subtracted from your gross pay before federal income tax is calculated. This lowers your taxable income, meaning you owe less in taxes. Common examples include:
- 401(k) Contributions: Money saved for retirement. In 2025, you can contribute up to $23,500 (or $31,000 if you are 50 or older). Maximizing this can significantly lower your tax bill. Use our Pay Raise Calculator to see how a salary increase might allow you to contribute more.
- Health Insurance Premiums: Your share of medical, dental, and vision costs is typically deducted pre-tax.
- HSA / FSA: Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) allow you to pay for medical expenses with pre-tax dollars. The 2025 HSA limit is $4,300 for individuals and $8,550 for families.
Post-Tax Deductions
These are taken out after taxes have been calculated. They reduce your net pay but do not lower your tax bill. Examples include:
- Roth 401(k) Contributions: You pay tax now to enjoy tax-free withdrawals later. This is a great option if you expect to be in a higher tax bracket in retirement.
- Wage Garnishments: Court-ordered payments for debts like child support or student loans.
- Union Dues: (In some cases).
How to Calculate Net Pay: The Formula
If you want to calculate your net pay manually, follow these steps. This is essentially the logic our Salary Calculator uses behind the scenes:
- Start with Gross Pay: Your total earnings for the period. If you are paid hourly, use our Hourly Wage Calculator to determine your total earnings.
- Subtract Pre-Tax Deductions: Remove 401(k), health insurance, etc.
- Calculate Federal Tax: Apply the 2025 tax brackets to the remaining amount (Taxable Income). You can verify these rates with our Federal Tax Calculator.
- Calculate FICA Tax: Apply 7.65% to your Gross Pay (adjusting for the SS cap).
- Calculate State Tax: Apply your state's tax rate to your Taxable Income. If you live in a specific state, check out our state-specific tools like the Florida Salary Calculator or Texas Salary Calculator.
- Subtract Post-Tax Deductions: Remove any Roth contributions or garnishments.
- Result: The remaining amount is your Net Pay.
Understanding Different Pay Frequencies
The frequency of your paycheck affects your cash flow, even if the total annual salary remains the same. Understanding your pay schedule helps you align your budget with your income. Here are the most common pay frequencies in the US:
Weekly (52 Paychecks)
Employees paid weekly receive a check every week, usually on Friday. This provides the most consistent cash flow but results in smaller individual checks. It is common for hourly workers in construction, manufacturing, and retail.
Bi-Weekly (26 Paychecks)
This is the most common pay frequency. Employees are paid every two weeks (e.g., every other Friday). Since there are 52 weeks in a year, this results in 26 paychecks.
Budgeting Tip: Most months will have two paychecks, but two months each year will have three. These "extra" checks are perfect for boosting savings or paying down debt.
Semi-Monthly (24 Paychecks)
Employees are paid twice a month, usually on the 1st and the 15th (or the 15th and the last day of the month). This results in exactly 24 paychecks per year. Each paycheck is slightly larger than a bi-weekly check (because the annual salary is divided by 24 instead of 26), and pay dates are consistent each month, which simplifies monthly bill payments.
Monthly (12 Paychecks)
Employees are paid once a month, typically at the end of the month. This results in the largest individual paychecks but requires the most discipline, as you must make that money last for the entire month. This frequency is less common but viewed in some corporate or executive roles.
Bonus Pay and Overtime
It's important to note that bonuses and overtime may be taxed differently.
Supplemental Wage Tax
Bonuses are often considered "supplemental wages" by the IRS. They can be taxed at a flat rate of 22% for federal income tax (up to $1 million), plus FICA and state taxes. This is why your bonus check might feel smaller than expected.
Overtime Pay
Overtime pay (time and a half) is taxed as regular income, but the extra money might push a portion of your paycheck into a higher tax bracket for that period, resulting in higher withholding. However, this usually balances out when you file your annual tax return.

Pro Tips for Maximizing Your Net Pay
While you can't avoid taxes entirely, there are smart ways to optimize your paycheck:
- Review Your W-4: Ensure you aren't over-withholding taxes. If you get a huge refund every year, you're giving the government an interest-free loan. Adjusting your W-4 can increase your monthly take-home pay.
- Maximize Pre-Tax Deductions: Contributing to a 401(k) or HSA lowers your taxable income, saving you money on taxes today while building wealth for tomorrow.
- Check State Tax Residency: If you work remotely, ensure you are being taxed in the correct state. Some states have no income tax, which can significantly boost your net pay.
