Child Support in Maryland

This post is for informational purposes only and is not legal advice. Every situation is different. Please consult a licensed attorney for guidance specific to your case.

If you are going through a separation or divorce in Maryland and children are involved, child support is probably one of the first things on your mind. You may have heard different numbers from different people and wondered how the court actually lands on a figure. The good news, Maryland uses a formula, and understanding the basics can help you feel more prepared.

How Maryland Calculates Child Support

Maryland uses the Income Shares Model. That means both parents’ incomes are combined, and each parent contributes a share of support proportional to what they earn.

The court looks at:

  • Gross income for both parents (wages, self-employment, rental income, bonuses, and more)

  • Number of children covered by the order

  • Health insurance costs for the children

  • Work-related childcare costs

  • Extraordinary medical expenses

  • Overnights each parent has (if shared custody applies)

What Can Increase or Decrease the Number

Factors that may increase support:

  • Higher income for the paying parent

  • Significant childcare costs

  • Special needs or medical expenses for the child

Factors that may decrease support:

  • More overnights with the paying parent (shared custody calculation)

  • Higher income for the receiving parent

  • Existing child support obligations for other children

What Does Not Impact the Calculation

This is where a lot of people get surprised. The following do not factor into Maryland’s child support formula:

  • Who caused the divorce or separation

  • Either parent’s new partner or spouse’s income (in most cases)

  • Personal spending habits or lifestyle choices

  • Whether one parent “deserves” more or less

The formula is designed to focus on the child’s needs, not the parents’ conflict.

Frequently Asked Questions

  • Can child support be changed later?

Yes. If there is a material change in circumstances, such as a significant income change or a shift in custody, either parent can request a modification.

  • What if a parent hides income?

Maryland courts can impute income if a parent is voluntarily underemployed or hiding earnings. An attorney can help you document this.

  • Is the formula always followed?

In most cases, yes. However, judges can deviate from the guidelines when the standard amount would be unjust or inappropriate.
