Tips for using the NC Child Support Calculator


  • Gather your financial information before starting calculations. Forgetting to add something will skew your results and may calculate an incorrect number. You can always go back if you forgot a number.
  • Use only whole numbers – if your number has a decimal point, round up if the value of the decimal point is .5 or more and round down if it is less.
    If an item does not apply to you, you may leave it blank or add a 0.
  • Your support amount is not set in stone until it is included in a signed separation agreement or a court order.
  • You may also use this calculator to calculate temporary child support orders.
  • Use these numbers as a guideline. You might find as you go through the divorce process that income changes, you accrue new debts or finances, or you discover funds you didn’t realize your spouse had.
