Does this calculator include Social Security and Medicare (FICA) withholding?

Not explicitly. The calculator focuses on income tax withholding using the federal and state percentages you enter. If you want to approximate FICA, you can increase your federal tax percentage to include roughly 6.2% for Social Security (up to the wage base) and 1.45% for Medicare, adjusting for your own situation.

Why don’t you model tax brackets or W‑4 allowances directly?

Paycheck withholding rules are complex and depend on filing status, credits, and IRS/state tables. This tool uses flat percentages to stay transparent and flexible. For exact withholding, your employer’s payroll system and official tax calculators are the authoritative sources.

Can I use this calculator if I am paid hourly instead of salaried?

Yes. You can estimate an annual salary by multiplying your hourly rate by typical hours worked per year, then use that number here. Just remember that overtime, fluctuating hours, and variable pay will make your actual paychecks differ from a simple average.

How should I choose the tax percentages to enter?

You can start with your current effective withholding rates from recent pay stubs or use approximate combined rates published for your income level. If in doubt, run a conservative scenario with slightly higher tax percentages so you do not overestimate your take‑home pay.

Is this calculator suitable for year‑end tax planning?

It is helpful for rough paycheck‑level planning but does not replace a full tax projection. For comprehensive year‑end planning that accounts for all income sources, deductions, and credits, use a dedicated tax planning tool or work with a tax professional.

Paycheck Calculator

Estimate take-home pay by entering salary, pay frequency, pretax contributions, and tax rates.

Results

Gross pay per period: $3,269 USD
Estimated taxes: $706 USD
Net pay per period: $2,363 USD

Overview

Your offer letter or salary might look impressive on paper, but what really matters for budgeting is how much shows up in your bank account each payday. This paycheck calculator helps you estimate take‑home pay by combining your annual salary, pay frequency, pretax deductions, and rough federal and state tax percentages. It is a simplified model of a paycheck that lets you quickly see the impact of changing your 401(k) contributions, adjusting tax assumptions, or switching between monthly and biweekly pay.

How to use this calculator

Enter your annual salary before any taxes or deductions.
Specify how many pay periods you have each year (for example, 12 monthly, 24 semi‑monthly, 26 biweekly, or 52 weekly).
Enter the total pretax deductions you expect per paycheck, such as retirement contributions or HSA funding.
Enter your estimated federal and state income tax percentages. You can also fold in Social Security, Medicare, or local taxes by increasing these percentages.
Run the calculation to see gross pay per period, estimated taxes, and net take‑home pay per paycheck.
Adjust pretax deductions or tax percentages to test different scenarios and see how your net pay changes.

Inputs explained

Annual salary: Your gross yearly pay before any taxes or deductions. For hourly roles, you can estimate this by multiplying your hourly rate by typical hours worked per year (for example, 2,080 hours for 40 hours per week × 52 weeks).
Pay periods per year: How many paychecks you receive in a typical year. Common values include 12 (monthly), 24 (semi‑monthly), 26 (biweekly), or 52 (weekly). This determines gross pay per period as salary divided by pay periods.
Pretax deductions per paycheck: The total amount taken out of your paycheck before income tax is calculated. Examples include 401(k) or 403(b) retirement contributions, HSA or FSA contributions, and some employer benefit premiums. These reduce the income that is subject to federal and state tax.
Federal tax %: An approximate percentage for federal income tax withholding on each paycheck. Instead of modeling brackets exactly, the calculator uses this flat rate to estimate how much federal tax is withheld.
State tax %: An approximate percentage for state income tax withholding. States vary widely: some have no income tax, while others have flat or graduated rates. Enter a rate that roughly matches your situation; you can also include local taxes here if you prefer.

Outputs explained

Gross pay per period: Your estimated paycheck amount before pretax deductions and taxes—annual salary divided by the number of pay periods.
Estimated taxes: The combined federal and state income tax withheld from the taxable portion of your paycheck, based on the percentages you entered.
Net pay per period: An estimate of how much you actually take home each pay cycle after pretax deductions and estimated income taxes. This is the number you would typically see deposited into your bank account, before any post‑tax deductions not modeled here.

How it works

You provide an annual salary and the number of pay periods per year. The calculator divides salary by pay periods to estimate gross pay per paycheck.

You enter a flat dollar amount of pretax deductions per paycheck—things like 401(k) contributions, HSA deductions, or certain pre‑tax benefit premiums.

The calculator subtracts those pretax deductions from gross pay to arrive at an approximate taxable amount for each paycheck.

You also enter federal and state tax percentages to approximate income tax withholding on that taxable pay. The tool sums those percentages into a combined effective tax rate.

Estimated taxes per paycheck are computed by multiplying the taxable amount by the combined tax rate.

Net pay per period is then taxable pay minus estimated taxes, showing a rough take‑home number for each paycheck.

Formula

Gross pay per period = annualSalary ÷ payPeriods\nTaxable pay per period = grossPay − pretaxContributions\nCombined tax rate = (federalTaxRate + stateTaxRate) in decimal form\nEstimated taxes = taxablePay × combinedTaxRate\nNet pay per period = taxablePay − estimated taxes

When to use it

Estimating take‑home pay for a new job offer so you can compare it to your current paycheck.
Testing how increasing or decreasing 401(k) or HSA contributions changes your net pay and tax withholding.
Comparing different pay schedules (monthly vs biweekly vs weekly) and how they affect cash‑flow timing.
Planning a budget or debt repayment schedule using an approximate net pay per paycheck.
Running rough what‑if scenarios for changes in tax rates, filing status, or pretax benefits before they show up on your actual pay stub.

Tips & cautions

Add approximate Social Security and Medicare (FICA) rates to your federal and state percentages if you want your tax estimate to more closely match real withholding.
If you contribute to multiple pretax benefits, sum them into the pretax deductions field so the calculator treats them all as reducing taxable pay.
Remember that bonuses and commissions may be taxed using different supplemental withholding rules and might not match the percentages you enter here.
Use slightly conservative tax percentages if you want to avoid overestimating net pay when planning a tight budget.
Revisit your assumptions if your salary, tax situation, or pretax contributions change significantly during the year.
The calculator uses flat percentage rates for federal and state income tax, while actual payroll systems apply progressive tax brackets, withholding tables, and other rules.
It does not include post‑tax deductions such as after‑tax benefit premiums, wage garnishments, or voluntary deductions taken after taxes.
It does not account for tax credits, filing status details, pre‑calculated allowances, or other nuances in W‑4 and state withholding forms.
Local, city, and other payroll taxes are not modeled separately; you must include them in the tax percentages if you want them reflected.
Results are per‑paycheck estimates only and are not a substitute for a full year‑end tax calculation or official payroll advice.

Worked examples

$85,000 salary, biweekly pay, $200 pretax, 18% federal, 5% state

Gross pay per period ≈ 85,000 ÷ 26 ≈ $3,269.
Pretax deductions = $200, so taxable pay ≈ $3,269 − $200 = $3,069.
Combined tax rate = 18% + 5% = 23% (0.23).
Estimated taxes ≈ $3,069 × 0.23 ≈ $706.
Net pay per period ≈ $3,069 − $706 ≈ $2,363.

Increase 401(k) contributions to $400 per paycheck with same salary and tax rates

Gross pay per period remains ≈ $3,269.
Pretax deductions now = $400, so taxable pay ≈ $3,269 − $400 = $2,869.
Combined tax rate still 23%.
Estimated taxes ≈ $2,869 × 0.23 ≈ $660.
Net pay per period ≈ $2,869 − $660 ≈ $2,209—lower take‑home, but more going into tax‑deferred savings and slightly lower taxes.

$60,000 salary, semi‑monthly pay (24 periods), no pretax, 15% federal, 5% state

Gross pay per period = 60,000 ÷ 24 = $2,500.
No pretax deductions, so taxable pay = $2,500.
Combined tax rate = 20% (0.20).
Estimated taxes = $2,500 × 0.20 = $500.
Net pay per period = $2,500 − $500 = $2,000.

Deep dive

This paycheck calculator estimates how much of your salary actually arrives in your bank account every pay cycle. By entering your annual salary, pay frequency, pretax deductions, and rough federal and state tax percentages, you can quickly see gross pay, estimated taxes, and net take‑home pay per paycheck. It is useful when evaluating job offers, planning 401(k) contributions, or building a monthly budget.

Because the tool simplifies withholding into flat percentages, it is not a replacement for payroll software or a full tax estimator. Instead, it gives you a fast way to visualize how changes in salary, benefits, or tax assumptions affect your net pay before those changes show up on your real pay stub.
