North Carolina Paycheck Calculator

If you’re a North Carolina resident, understanding your actual take-home pay is crucial for budgeting and financial planning. Between federal taxes, state taxes, FICA contributions, and optional retirement deductions like a 401(k), your gross salary can shrink significantly by the time it hits your bank account. That’s why we’ve built the NC Paycheck Calculator — a fast, free, and accurate tool that gives you a detailed breakdown of your paycheck based on your income, pay frequency, and tax information.

This guide will walk you through how the tool works, how to use it effectively, and what to keep in mind when reviewing your paycheck results.

What Is the NC Paycheck Calculator?

The NC Paycheck Calculator is a web-based tool that estimates your net income — the amount you actually take home — after deductions like:

  • Federal income tax
  • North Carolina state income tax (4.75% flat rate as of 2025)
  • FICA (Social Security and Medicare taxes)
  • 401(k) retirement contributions
  • Additional withholdings and federal allowances

By entering a few simple details, you can calculate how much you’ll see in your paycheck for any pay period (weekly, bi-weekly, semi-monthly, or monthly).

Step-by-Step Guide: How to Use the NC Paycheck Calculator

1. Enter Your Gross Income

Input your gross income for one pay period, not annually. For example, if you’re paid bi-weekly and earn $2,000 every two weeks, enter “2000”.

2. Select Your Pay Frequency

Choose from:

  • Weekly
  • Bi-Weekly
  • Semi-Monthly
  • Monthly

The calculator will use this to annualize your income and determine the correct tax brackets and deductions.

3. Choose Your Filing Status

Pick your current tax filing status:

  • Single
  • Married Filing Jointly
  • Head of Household

This affects your federal tax rate and thresholds.

4. Input Federal Allowances

Federal allowances reduce your taxable income. While the IRS has phased out traditional allowances for Form W-4 (post-2020), this field lets you estimate their effect for older W-4 setups.

5. Enter Additional Withholding (Optional)

If you requested extra withholding on your W-4, input that amount here. This amount will be deducted from your gross income before net pay is calculated.

6. Add Your 401(k) Contribution Percentage (Optional)

If you’re contributing a portion of your income to a traditional 401(k), enter the percentage. This reduces your taxable income for federal and state taxes.

7. Click “Calculate”

After inputting your details, hit the Calculate button. Your results will appear below the form, showing:

  • Gross pay
  • Federal tax
  • NC state tax
  • Social Security (FICA)
  • Medicare (including additional Medicare tax if applicable)
  • 401(k) contribution
  • Final net pay

Example: Calculating a Bi-Weekly Paycheck in North Carolina

Let’s say you earn $2,000 bi-weekly, are single, and contribute 5% to a 401(k). You claim no allowances and have no additional withholdings.

  • Gross Pay: $2,000
  • 401(k) Contribution: $100 (5% of $2,000)
  • Taxable Income: $1,900
  • Federal Tax: Based on single bracket and simplified rate
  • NC State Tax: 4.75% of $1,900 = $90.25
  • FICA: 6.2% of $1,900 = $117.80
  • Medicare: 1.45% of $1,900 = $27.55
  • Net Pay: ~$1,664.40

This shows you how deductions quickly reduce your take-home pay — essential information when planning your monthly budget.
