Net Take-Home Pay: $0.00

How Your Net Paycheck is Calculated

Understanding your net paycheck is critical for budgeting. While your "Gross Salary" is the number on your offer letter, the "Net Pay" (also known as take-home pay) is what actually hits your bank account after mandatory and voluntary withholdings.

1. Gross Pay per Period

The first step is dividing your annual salary by the number of pay periods in a year. For example, if you earn $65,000 and are paid bi-weekly, your gross pay per check is $2,500 ($65,000 / 26).

2. Mandatory Tax Withholdings

  • Federal Income Tax: This depends on your tax bracket, filing status, and allowances. This calculator uses a simplified percentage estimate.
  • FICA (Social Security & Medicare): In the US, employees typically pay 6.2% for Social Security and 1.45% for Medicare, totaling 7.65% on most earnings.
  • State Income Tax: This varies significantly by state, with some states (like Florida or Texas) having 0% tax and others reaching over 10%.

3. Deductions

Deductions can be Pre-tax (like 401k contributions or health insurance premiums) or Post-tax (like disability insurance or Roth contributions). Pre-tax deductions are beneficial because they reduce the amount of your income that is subject to federal taxes.

Real-Life Example

Let's say Jane earns $60,000 a year and gets paid monthly. Her gross monthly pay is $5,000. If her combined federal and state tax rate is 15% ($750) and her FICA is 7.65% ($382.50), and she contributes $300 to a health insurance plan, her calculation looks like this:

$5,000 (Gross) – $750 (Income Tax) – $382.50 (FICA) – $300 (Health) = $3,567.50 (Net)

function calculateNetPay() { // Get values var grossSalary = parseFloat(document.getElementById("grossSalary").value); var payPeriods = parseFloat(document.getElementById("payFrequency").value); var fedTaxRate = parseFloat(document.getElementById("fedTax").value) / 100; var stateTaxRate = parseFloat(document.getElementById("stateTax").value) / 100; var preTaxDeductions = parseFloat(document.getElementById("preTaxDeduction").value); var postTaxDeductions = parseFloat(document.getElementById("postTaxDeduction").value); // Validate inputs if (isNaN(grossSalary) || grossSalary <= 0) { alert("Please enter a valid gross salary."); return; } // Gross per period var grossPerPeriod = grossSalary / payPeriods; // FICA calculation (7.65%) var ficaRate = 0.0765; var ficaAmount = grossPerPeriod * ficaRate; // Pre-tax deductions affect taxable income var taxableIncomePerPeriod = grossPerPeriod – preTaxDeductions; if (taxableIncomePerPeriod < 0) taxableIncomePerPeriod = 0; // Federal and State Taxes var fedTaxAmount = taxableIncomePerPeriod * fedTaxRate; var stateTaxAmount = taxableIncomePerPeriod * stateTaxRate; // Final Net Pay Calculation // Formula: Gross – Fed Tax – State Tax – FICA – Pre-tax Deductions – Post-tax Deductions var netPay = grossPerPeriod – fedTaxAmount – stateTaxAmount – ficaAmount – preTaxDeductions – postTaxDeductions; if (netPay < 0) netPay = 0; // Format currency function formatMoney(num) { return "$" + num.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2}); } // Display Results document.getElementById("resGrossPeriod").innerText = formatMoney(grossPerPeriod); document.getElementById("resFedTax").innerText = "-" + formatMoney(fedTaxAmount); document.getElementById("resStateTax").innerText = "-" + formatMoney(stateTaxAmount); document.getElementById("resFica").innerText = "-" + formatMoney(ficaAmount); document.getElementById("resVoluntary").innerText = "-" + formatMoney(preTaxDeductions + postTaxDeductions); document.getElementById("resNetPay").innerText = formatMoney(netPay); document.getElementById("resultArea").style.display = "block"; }
