How Maine Child Support Is Calculated

Maine uses the Income Shares Model to determine child support obligations. Maine uses the Income Shares model based on both parents' gross monthly incomes. Maine has detailed child support tables and includes adjustments for health insurance and childcare. Support typically ends at age 18.

Maine applies a parenting time adjustment when the non-custodial parent has at least 30% of the annual parenting time. For shared parenting arrangements, Maine uses the offset method to calculate net support.

Maine courts use the Income Shares Model worksheets for official calculations. Maine does not provide an official public calculator. The Maine Department of Health and Human Services provides child support enforcement services. Consult a family law attorney for calculations.

Worked Example: Maine Child Support

Alex earns $5,500/month gross income. Jordan earns $3,200/month. They have 2 children in Maine. Alex has primary custody; Jordan has standard visitation (every other weekend, approximately 73 overnights/year).

Combined monthly income: $5,500 + $3,200 = $8,700
Basic support (2 children, ~25% of combined): $8,700 × 25% = $2,175/month
Jordan's income share: $3,200 / $8,700 = 36.8%
Jordan's proportional share: $2,175 × 36.8% = $800/month
Health insurance add-on (paid by Alex, Jordan's share): +$74/month
Childcare add-on (Jordan's proportional share of $600): +$221/month
Custody adjustment (73 nights — no adjustment): $0
ESTIMATED SUPPORT: ~$1,095/month

This example uses approximate calculations. Actual Maine child support requires the official Income Shares Model worksheet or software and should be verified with a licensed family law attorney or the court.

Key Factors That Affect Maine Child Support

  • Both Parents' Income

    Maine's Income Shares Model combines both parents' incomes to determine the total family resources available for the children. A higher combined income results in higher support — reflecting the idea that children should benefit from the family's overall financial resources regardless of which parent they primarily reside with.

  • Custody and Parenting Time

    Maine adjusts child support based on the amount of parenting time each parent has. More overnight time with the paying parent generally reduces the support obligation — reflecting that the paying parent directly absorbs the children's costs during their parenting time. Maine applies a parenting time adjustment when the non-custodial parent has at least 30% of the annual parenting time.

  • Health Insurance and Childcare

    Health insurance premiums for the children and work-related childcare costs are added to the basic child support obligation in Maine. The cost is typically split proportionally based on each parent's share of combined income. These add-ons can significantly increase the total support obligation, particularly in cases with high childcare or health insurance costs.

Frequently Asked Questions

How is child support calculated in Maine?

Maine uses the Income Shares Model to calculate child support. Maine uses the Income Shares model based on both parents' gross monthly incomes. The guideline amount is the starting point, but courts may deviate based on special circumstances such as a child's extraordinary medical needs, travel costs for visitation, or significantly different financial situations from the guideline assumptions. Always confirm your specific calculation with a Maine family law attorney.

What income is used to calculate child support in Maine?

Maine uses both parents' gross monthly income as the starting point for child support calculations, combining them into a total family income figure. Courts may also impute income to a parent who is voluntarily underemployed or unemployed without good cause — meaning they may be held to what they could earn rather than what they actually earn.

Does 50/50 custody mean no child support in Maine?

No. In Maine, shared custody reduces but does not eliminate child support in most cases. When both parents share custody equally, Maine typically uses an offset method where each parent's guideline support is calculated and the higher earner pays the difference. The goal is to ensure the children maintain a similar standard of living in both households. If incomes are nearly equal, the resulting payment may be very small, but it rarely drops to zero unless incomes are identical.

How long does child support last in Maine?

In Maine, child support generally continues until the child reaches the age of majority (typically age 18), graduates from high school, or is otherwise emancipated — whichever occurs later up to the state maximum. Courts may also continue support for adult disabled children who cannot support themselves. Support does not automatically end — the paying parent must file for termination when the child ages out or becomes emancipated.

Can Maine child support be modified?

Yes. Maine child support can be modified when there is a substantial change in circumstances. Most states, including Maine, require that the new calculated amount differ from the existing order by at least 15% — or that three years have passed since the order was entered, triggering an automatic review. Changes that typically qualify include significant income changes for either parent, a change in custody arrangement, a child's new medical needs, or loss of health insurance coverage. Modifications require filing a motion with the family court — the original order remains in effect until a new order is entered.
