Boston Paycheck Calculator 2025 – Quickly Calculate Your Net Pay for Free

The Boston Paycheck Calculator helps Massachusetts employees estimate their bi-weekly take-home pay by factoring in federal income tax, Massachusetts state income tax, Social Security, Medicare, Paid Family and Medical Leave (PFML), and any pre-tax deductions such as health insurance or 401(k) contributions.

This easy-to-use tool is ideal for professionals living or working in Boston who want to understand how much they’ll actually take home after all mandatory withholdings and benefits are applied.

How the Calculator Works

This tool calculates your net paycheck by starting with your gross income and subtracting all applicable taxes and pre-tax contributions.

Input Fields Explained

1. Annual Gross Salary ($)
   • Your total income before taxes and deductions.
   • Example: Enter “75000” for a $75,000 annual salary.
2. Pay Frequency
   • Set to Bi-Weekly (26 pay periods/year) for accurate paycheck timing.
3. Pre-Tax Deductions Per Period ($)
   • Include amounts deducted before taxes, like health insurance or 401(k) contributions.
   • Example: $150 per paycheck.
4. Federal Filing Status (W-4)
   • Select your IRS filing status (e.g., Single, Married Filing Separately), which influences federal withholding rates.
5. Dependents Claim Amount (W-4 Step 3)
   • Enter the total claimed on your W-4 for dependents. This can reduce your taxable income.
6. MA State Exemptions (M-4)
   • Massachusetts allows exemptions for state taxes. Enter the number of exemptions claimed on your M-4 form.

Core Calculation Formula

Gross Pay Per Period = Annual Salary ÷ 26
Taxable Income = Gross Pay - Pre-Tax Deductions

Estimated Deductions:
- Federal Income Tax (based on filing status)
- Massachusetts State Income Tax (5% flat rate, adjusted for exemptions)
- Social Security Tax (6.2%)
- Medicare Tax (1.45%)
- MA PFML (approx. 0.318% subject to cap)

Net Pay = Gross Pay - Pre-Tax Deductions - Total Estimated Taxes

The result is your estimated bi-weekly take-home pay. If you’re paid twice a month, the Bi-Weekly Calculator is the right tool for you.
