Deductions & Taxes
Every employee wonders, “How much will I actually take home?” Your paycheck reflects more than just your hourly rate or salary—it accounts for federal and state taxes, Social Security, Medicare, and other deductions.
A Paycheck Calculator helps you estimate your take-home pay quickly and accurately. Whether you’re hourly, salaried, or freelance, this tool calculates gross pay, tax withholdings, and net income so you can budget confidently and plan for expenses.
How a Paycheck Calculator Works
The calculator considers the following:
- Income type: Salary or hourly
- Work hours (for hourly employees)
- Pay frequency: Weekly, bi-weekly, semi-monthly, monthly
- Filing status: Single, Married, Head of Household
- Pre-tax deductions: 401(k), health insurance, HSA contributions
- Post-tax deductions: Garnishments, insurance premiums
- State taxes (if applicable)
Output:
- Gross pay
- Federal tax withholding
- FICA taxes (Social Security & Medicare)
- State taxes (optional)
- Net pay (take-home pay)

- Click Calculate to view gross pay, taxes, and net pay.
The Calculation Formula
- Gross Pay
- Salary:
Annual Salary ÷ Pay Periods - Hourly:
Hourly Rate × Hours Worked
- Salary:
- Pre-Tax Deductions
- Subtract 401(k), HSA, and pre-tax insurance contributions
- Taxable Income
- Gross Pay – Pre-Tax Deductions
- Federal Withholding
- Calculated based on IRS tax tables and filing status
- FICA Taxes
- Social Security = 6.2% of taxable income (up to annual cap)
- Medicare = 1.45% (+0.9% for high earners)
- State Taxes
- Varies by state; some states have no income tax (Texas, Florida)
- Post-Tax Deductions
- Subtract any after-tax contributions or garnishments
- Net Pay
- Taxable income – federal + state taxes – FICA – post-tax deductions
Worked Example
Scenario:
- Single filer
- Annual salary: $50,000
- Bi-weekly pay (26 pay periods)
- Pre-tax 401(k) contribution: 5%
- State: California
Step 1: Gross Pay
$50,000 ÷ 26 = $1,923.08
Step 2: Pre-tax deduction (401k 5%)
$1,923.08 × 5% = $96.15
Taxable income = $1,923.08 – $96.15 = $1,826.93
Step 3: Federal tax withholding
Approx. $220 (IRS tables)
Step 4: FICA Taxes
- Social Security: $1,826.93 × 6.2% = $113.25
- Medicare: $1,826.93 × 1.45% = $26.50
Step 5: State Income Tax (CA)
Approx. $90
Step 6: Net Pay
$1,826.93 – ($220 + $113.25 + $26.50 + $90) = $1,377.18
✅ Take-Home Pay = $1,377.18 per paycheck
