Child Support Calculator Minnesota - Guidelines & Rates

Overview

Minnesota child support is calculated under Minn. Stat. § 518A.34 using the state’s statutory guideline framework, which includes a basic support schedule tied to combined monthly net income.

In practice, DocketMath’s Alimony/Child Support calculator turns that framework into a step-by-step workflow—so you can see how the estimated amount changes when you adjust key inputs (especially combined monthly net income).

This calculator can also model maintenance (alimony), but it’s important to keep the two categories distinct:

• Child support: Minn. Stat. § 518A.34
• Maintenance (alimony): Minn. Stat. § 518.552 (modeled using separate, discretion-based factors rather than the child support schedule approach)

What DocketMath needs (typical inputs)

To generate results, you generally enter:

• The parties’ net incomes (or inputs that the tool converts into net figures)
• The number of children involved (and any tool-supported scheduling assumptions)
• Any case flags the tool requests
• If you’re running the combined tool: maintenance-related inputs in addition to the child support inputs

What you’ll see in outputs

DocketMath’s Minnesota output is built around the schedule logic keyed to combined monthly net income and applies guardrails reflected in the tool’s Minnesota settings, including:

• A basic support amount derived from the schedule table values keyed to combined monthly net
• A minimum support order floor of $50 (so results won’t be modeled below that threshold)

Limitation period

Minnesota’s child support “limitation period” concept is addressed in the statute governing child support provisions. Because limitation-period mechanics can depend on how your timeline is framed (for example, how you’re modeling a past time window vs. prospective support), it’s best to use the calculator consistently with your fact pattern.

Use this practical approach:

• Lock your time window first: decide what months you are calculating for (not just the income numbers).
• Re-run if dates change: a small change to a start/end month can change totals if the limitation period you’re modeling affects which months count.
• Treat outputs as estimates: DocketMath is a planning tool for guideline-style modeling, not a guarantee of a court’s retroactive calculation.

How to approach the limitation period in a calculator

A simple workflow that helps:

1. Choose the start month and end month you want to model.
2. Enter your income inputs.
3. Run the estimate, then adjust only one variable at a time (for example, income or dates) to see how totals change.

Key exceptions

Minnesota guideline calculations can change meaningfully when exception-style adjustments apply. When reviewing DocketMath results, focus on these high-impact areas the calculator reflects in its Minnesota settings.

1) Minimum support order floor

DocketMath enforces minimum support order = $50 in its Minnesota logic.

That means:

• If your modeled guideline result would fall below $50, the tool will not output less than $50 for the child support portion.

2) Schedule modeling with an income cap (presumptive)

Minnesota schedule treatment in the tool includes an income cap used for presumptive schedule modeling:

• Income cap: $20,000
• Income cap type: presumptive

Practical takeaway:

• Below the cap, modeled support is more likely to track movements in combined monthly net through the schedule table.
• Near or above the cap, additional income may produce less predictable or limited schedule movement within the table-based model.

3) Maintenance (alimony) is separate and discretion-based

If you use the combined alimony/child support tool, remember:

• Maintenance is governed by Minn. Stat. § 518.552
• Maintenance may be temporary, rehabilitative, or permanent and is handled through factors rather than the child support schedule structure.

So, treat the maintenance portion as a modeled output that depends on the tool’s maintenance section, not as the same kind of schedule-driven computation as child support.

Statute citation

The primary statutory anchor for Minnesota child support guidelines in this calculator is:

• Minn. Stat. § 518A.34 (child support)
  https://www.revisor.mn.gov/statutes/cite/518A.34

If you are also modeling maintenance (alimony) using the combined tool:

• Minn. Stat. § 518.552 (maintenance)
  https://www.revisor.mn.gov/statutes/cite/518.552

Use the calculator

DocketMath’s Alimony/Child Support tool is intended to help you understand how Minnesota-style schedule outputs respond to your inputs.

Step-by-step: run a Minnesota estimate

1. Open DocketMath’s calculator: /tools/alimony-child-support
2. Select Minnesota jurisdiction settings (as prompted by the tool).
3. Enter values that produce or correspond to combined monthly net income.
4. Confirm the number of children and any schedule assumptions the tool requests.
5. If relevant, run the maintenance portion too (using the calculator’s maintenance section).

Example schedule touchpoints (combined monthly net)

The calculator’s Minnesota schedule table includes entries keyed to combined monthly net. Examples reflected in the tool’s Minnesota schedule dataset include:

• $1,399 → schedule_table.0.combined_monthly_net
• $1,499 → schedule_table.1.combined_monthly_net
• $3,999 → schedule_table.10.combined_monthly_net
• $4,499 → schedule_table.11.combined_monthly_net
• $4,999 → schedule_table.12.combined_monthly_net
• $5,999 → schedule_table.14.combined_monthly_net
• $6,099 → schedule_table.15.combined_monthly_net
• $6,999 → schedule_table.16.combined_monthly_net
• $7,999 → schedule_table.17.combined_monthly_net
• $8,999 → schedule_table.18.combined_monthly_net
• $9,999 → schedule_table.19.combined_monthly_net
• $10,999 → schedule_table.20.combined_monthly_net
• $11,999 → schedule_table.21.combined_monthly_net
• $12,999 → schedule_table.22.combined_monthly_net
• $13,999 → schedule_table.23.combined_monthly_net
• $14,999 → schedule_table.24.combined_monthly_net
• $15,999 → schedule_table.25.combined_monthly_net
• $16,999 → schedule_table.26.combined_monthly_net
• $17,999 → schedule_table.27.combined_monthly_net
• $18,999 → schedule_table.28.combined_monthly_net
• $19,999 → schedule_table.29.combined_monthly_net
• $20,000 (cap) → schedule_cap_combined_monthly_pics = $20,000

How outputs change when you adjust inputs

To get actionable results, change one input at a time:

• If combined monthly net increases: the guideline output can move to a different schedule table range.
• If combined monthly net decreases: the output can step down to a lower range.
• If the modeled result would be below $50: the calculator applies the $50 minimum support order floor.
