Paycheck Calculator: Estimate Take-Home Pay From Gross Income

The Paycheck Calculator estimates take-home pay from gross income, pay frequency, filing status, pre-tax deductions, FICA, simplified federal tax math, and a user-entered state tax estimate.

This tool is designed for educational use. It does not calculate official payroll withholding, prepare a W-4, replace payroll software, or determine actual tax owed.

A paycheck can look different from annual salary because each pay period separates gross pay, deductions, taxes, and estimated take-home pay. This calculator makes those layers easier to see in one place.

Educational tax math note: This calculator explains simplified paycheck math for informational purposes only. It does not provide tax, legal, payroll, accounting, benefits, employment, or financial advice.

How This Paycheck Calculator Works

The calculator starts with gross pay. Gross pay can be entered as an annual salary or as an hourly wage with hours per week. The tool then annualizes the pay and divides it back into the selected pay frequency.

The basic structure is:

Gross pay − estimated taxes − deductions = estimated take-home pay

For federal income tax, this calculator uses a simplified annual model. It subtracts the 2026 standard deduction for the selected filing status, applies the 2026 federal tax brackets to the remaining taxable income estimate, and then divides the annual estimate by the number of pay periods.

This is different from official payroll withholding. Employers generally use IRS Publication 15-T, Form W-4 information, and payroll-specific withholding methods to calculate federal withholding.

Paycheck Math Breakdown

A paycheck is easier to read when the layers are separated. A simplified paystub-style breakdown may look like this:

The calculator shows the result as an estimate per paycheck, per month, and per year. It also includes a visual breakdown of take-home pay, taxes, and deductions.

What FICA Includes

FICA is made up of Social Security tax and Medicare tax. The IRS lists the employee Social Security tax rate as 6.2% and the employee Medicare tax rate as 1.45%.

Only Social Security has an annual wage base limit. For earnings in 2026, the Social Security wage base is $184,500. Medicare tax does not have the same wage base limit.

This calculator estimates standard employee FICA using those rates. It does not calculate every possible payroll situation, employer treatment, Additional Medicare Tax, or special wage category.

Why Pay Frequency Changes the Paycheck Number

The same annual income can produce different paycheck amounts depending on how often pay is issued.

A bi-weekly paycheck is not the same as a semi-monthly paycheck. Bi-weekly pay usually creates 26 paychecks per year. Semi-monthly pay usually creates 24 paychecks per year.

Pre-Tax vs. Post-Tax Deductions

Pre-tax and post-tax deductions affect paycheck math differently.

In this simplified calculator, pre-tax deductions are subtracted before the federal taxable income estimate is calculated. Post-tax deductions are subtracted after the tax estimates.

Gross pay − pre-tax deductions = simplified income base before federal tax estimate

Real payroll systems can treat benefits differently depending on the type of deduction, employer plan, state rules, and payroll setup. This calculator keeps the structure simple so the cash-flow layers remain visible.

State Tax Estimate Note

State income tax rules vary widely. Some states do not have a broad wage income tax. Other states have flat rates, progressive rates, local rules, credits, deductions, or special payroll formulas.

For that reason, this calculator uses a state selection plus an editable state tax estimate percentage. Selecting a state with no broad wage income tax sets the estimate to 0%. For other states, the user can adjust the percentage manually.

This is not official state withholding. It is only a simplified modeling input.

Leftover Money After Paycheck

Take-home pay is often only the first question. The next question is how much of that take-home pay remains after fixed monthly bills.

The leftover money section uses this simple formula:

Estimated monthly take-home pay − monthly fixed bills = estimated money left after bills

For a deeper explanation of this idea, see The Leftover Money Method.

What This Calculator Does Not Include

This calculator is intentionally simplified. It does not calculate official withholding or actual tax owed.

It does not include:

• official W-4 withholding calculations;
• the full IRS Publication 15-T withholding process;
• all state and local withholding rules;
• city, county, school district, or local payroll taxes;
• credits, dependents, itemized deductions, or additional W-4 adjustments;
• bonuses, commissions, supplemental wages, RSUs, stock compensation, or tips;
• overtime rules beyond the hourly wage and hours entered;
• Additional Medicare Tax;
• employer-specific benefits or deduction treatment;
• pre-tax deduction differences for FICA, state wages, or employer plans;
• unemployment insurance, workers compensation, or employer payroll taxes;
• tax refunds, balances due, penalties, or filing outcomes.

The calculator should be read as an educational paycheck estimate, not a payroll system.

When the IRS Tax Withholding Estimator May Be More Appropriate

The IRS provides an official Tax Withholding Estimator for people who want to review federal withholding more directly. That tool is designed around official withholding inputs and individual tax details.

This WLH calculator is different. It focuses on the visible math relationship between gross pay, pay frequency, deductions, simplified tax estimates, and estimated take-home pay.

FAQ

Educational Use Only

This calculator is provided for educational and informational purposes only. It does not provide tax advice, legal advice, payroll advice, accounting advice, employment advice, benefits advice, financial advice, or professional guidance.

The calculator does not determine actual tax owed, official payroll withholding, refund amount, balance due, eligibility for deductions or credits, W-4 settings, state withholding, local withholding, or employer-specific payroll treatment. Payroll and tax outcomes can vary by Form W-4, employer payroll settings, filing status, dependents, credits, deductions, benefits, state rules, local rules, and individual circumstances.

For official federal withholding review, use official IRS resources or consult a qualified tax or payroll professional.
