When your employer determines your take-home pay, they deduct federal and state income taxes, along with contributions to Social Security and Medicare. The exact amount withheld from each paycheck depends on key factors such as your earnings, filing status, and the number of dependents you claim.
Understanding your take-home pay is essential for managing your finances effectively. A paycheck calculator helps you estimate how much of your salary you’ll actually receive after deductions for federal, state, and local taxes, as well as contributions to Social Security, Medicare, health insurance, and retirement plans. Whether you’re starting a new job, negotiating a raise, or adjusting your withholdings, this tool provides a clear breakdown of your earnings. By using a paycheck calculator, you can plan your budget with confidence and ensure you’re prepared for any tax obligations or deductions that impact your income.

How Your Paycheck Works: Income Tax Withholding
When you start a new job or receive a raise, you’ll agree to either an hourly wage or an annual salary. However, determining your actual weekly take-home pay involves more than just multiplying your hourly wage by the hours worked or dividing your yearly salary by 52. This is because your employer deducts taxes from each paycheck, reducing your overall earnings. With multiple taxes withheld at varying rates, calculating your net pay can be complex—that’s where our paycheck calculator helps.
Understanding Tax Withholding
Tax withholding refers to the portion of your paycheck that is deducted to cover taxes, with federal income tax being the most significant component. The IRS requires employers to withhold these taxes throughout the year based on the details provided in your Form W-4. You must complete and submit this form when starting a new job, and you may need to update it after significant life changes such as marriage.
If you update your W-4, your employer must adjust your paycheck accordingly. While most U.S. employees have federal income taxes withheld, some individuals qualify for an exemption. To be exempt, you must meet both of the following criteria:
- You received a full refund of all federal income tax withheld last year because you had zero tax liability.
- You expect to receive a full refund of all federal income tax withheld this year because you have zero tax liability again.
If you qualify, you can claim an exemption on your W-4 Form.

When managing tax withholdings, employees face a trade-off between receiving larger paychecks and potentially owing more in taxes. The current W-4 form has removed the option to claim allowances, as well as personal and dependency exemptions. Instead, it requires filers to enter specific dollar amounts for annual taxable wages, non-wage income, and deductions. The updated form also includes a five-step process for reporting personal information, additional income, and dependents.
Adjusting Your Tax Withholding
One way to manage your tax bill is by adjusting your withholdings. If you choose to maximize your paycheck, you may owe taxes when filing in April if not enough was withheld throughout the year. This could result in an unexpected tax bill rather than a refund.
On the other hand, opting for higher tax withholdings ensures more is taken out of each paycheck, reducing the likelihood of owing taxes and increasing your chances of receiving a refund. However, this also means you are giving the government an interest-free loan with every paycheck.
Alternatively, selecting lower withholdings allows you to keep more of your earnings throughout the year. This extra money can be used for investing, saving in a high-interest account, or paying off debt—potentially providing more excellent financial benefits over time.
Fine-Tuning Your W-4
When completing your W-4 form, worksheets are available to help determine the correct withholding amount based on various factors. These include marital status, number of children, employment status (whether you have multiple jobs), filing status, and whether someone else claims you as a dependent. You can also account for expected tax deductions and credits.
Additionally, if you want more control over your tax liability, you can request a specific additional dollar amount to be withheld from each paycheck. This allows for more precise tax planning and helps ensure you meet your tax obligations without surprises.

How Your Paycheck Works: FICA Withholding
In addition to federal income tax withholding, a key component of your paycheck deductions is FICA taxes. FICA, which stands for the Federal Insurance Contributions Act, funds Social Security and Medicare—programs that provide financial and healthcare benefits during retirement. These payroll taxes ensure that you contribute to the system that will support you later in life.

How FICA Taxes Are Calculated
FICA taxes are split between employees and employers. Social Security tax accounts for 6.2% of each paycheck, with your employer contributing an additional 6.2%. However, this tax only applies to earnings up to a specific limit.
- For 2024, the Social Security tax cap is $168,600
- For 2025, the cap increases to $176,100
Any income earned above this limit is not subject to Social Security taxes. However, Medicare taxes still apply to all earnings, as there is no income limit for Medicare contributions.
Medicare Taxes & Additional Medicare Surtax
The standard Medicare tax rate is 1.45%, with employers also contributing an additional 1.45%. However, high earners are required to pay an additional 0.9% Medicare surtax on income exceeding the following thresholds:
- $200,000 for single filers, heads of household, and qualifying widow(er)s with dependent children
- $250,000 for married couples filing jointly
- $125,000 for married taxpayers filing separately
FICA Taxes for Self-Employed Individuals
If you’re self-employed, you are responsible for both the employee and employer portions of FICA taxes, which equals 15.3% total (12.4% for Social Security and 2.9% for Medicare). However, when filing your taxes, you can deduct the employer-equivalent portion, effectively reducing your taxable income and balancing the tax burden.
How Your Paycheck Works: Deductions
Federal income tax and FICA tax withholding are mandatory, meaning they cannot be avoided unless your earnings are very low. However, these are not the only factors that impact your paycheck. Various deductions also play a role in determining your take-home pay.
One ordinary deduction is the amount you pay toward employer-sponsored health insurance. If you enroll in your company’s health plan, a portion of your paycheck will be allocated to cover your selected coverage. Additionally, contributions to a Health Savings Account (HSA) or Flexible Spending Account (FSA) for medical expenses are deducted before taxes, reducing your taxable income.
Retirement contributions also affect your paycheck. Pre-tax contributions, such as those made to a 401(k) or 403(b) plan, are deducted before taxes are applied. If you choose to contribute 10% of your salary to your company’s 401(k), that percentage is taken from each paycheck. Increasing contributions will result in smaller paychecks but will also lower your taxable income. The money in these accounts grows tax-free, and taxes are only paid upon withdrawal, ideally after significant growth.
Some deductions, however, are made after taxes are applied. Roth 401(k) contributions, for example, come from post-tax earnings. Unlike pre-tax retirement accounts, the advantage of a Roth IRA or Roth 401(k) is that your money grows tax-free, and withdrawals in retirement are not subject to income tax since taxes were already paid on the contributions. This can be especially beneficial for individuals early in their careers or those expecting to earn a higher income in the future, as it can result in significant long-term tax savings.
How Your Paycheck Works: Pay Frequency
Some employees receive monthly paychecks (12 per year), while others are paid twice a month on specific dates (24 paychecks per year) or bi-weekly (26 paychecks per year). The frequency of your pay directly impacts the size of each paycheck. The more often you are paid, the smaller each paycheck will be—assuming your annual salary remains the same.
How Your Paycheck Works: Local Factors
If you reside in a state or city that imposes income taxes, these will also impact your take-home pay. Similar to federal income taxes, your employer will deduct a portion of each paycheck to cover state and local tax obligations.
