Wisconsin High Income Child Support Calculator

When the paying parent's income available for child support tops $7,000 a month, which is $84,000 a year, Wisconsin courts can apply reduced percentages to the income above that line.^[1] The standard rates always hold on the first $7,000, a lower set can apply between $7,000 and $12,500, and a lower set still can apply above $12,500. Enter income and number of children below, and the calculator shows every band and the total.

The word can is doing real work in that sentence. The reductions above $7,000 are the court's choice, not the payer's right, and plenty of orders never use them. High income cases also draw the closest scrutiny on what counts as income in the first place, from bonuses to business earnings.

Please read before you start. This is an estimate, not a court order. It applies the high-income provisions in Wis. Admin. Code § DCF 150.04(4) to the figures you enter, stepping the standard percentage down across income tiers. Whether to apply the reduced rates is up to the court, and high-income cases often turn on income that is not a paycheck, including bonuses, distributions, deferred compensation, and business earnings. Under Wis. Stat. § 767.511(1m) a court can order a different amount. Using this tool does not create an attorney-client relationship with Sterling Lawyers and nothing here is legal advice.

Is this the right calculator for you?

Use it when the paying parent's monthly income available for support runs above $7,000, one parent has primary placement, and no other special circumstances apply. Different facts point to a different tool.

• Income is $7,000 a month or less. The standard percentages cover all of it, through the main Wisconsin child support calculator.
• Both parents have at least 92 overnights. Courts can blend the tiers with the shared formula, so a standalone tier result will not match your case. Start with the shared placement child support calculator and treat the combination as attorney territory.
• The paying parent has an earlier support order. That obligation adjusts the income before the tiers run, so use the serial family child support calculator first and enter the adjusted figure here.
• Split or combined placement structures. The tiers can combine with those formulas too. The calculator flags the situation, and an attorney should run the blend before anyone relies on a number.

How the three income tiers work

Wisconsin does not stop counting income at $84,000; it steps the percentage down in bands, and every dollar lands in exactly one band.^[3] Here is the full table by number of children.

Monthly income band	1 child	2 children	3 children	4 children	5 or more
First $7,000	17%	25%	29%	31%	34%
$7,000 to $12,500	14%	20%	23%	25%	27%
Above $12,500	10%	15%	17%	19%	20%

The design is simpler than it looks. The middle band runs at roughly 80 percent of the standard rates and the top band at roughly 60 percent, which is exactly how the state describes it. The mandatory and discretionary split matters just as much: the code says the court shall apply the standard percentages below $7,000 and may apply the reduced sets above it.

A worked example

Take a paying parent with $15,000 a month in income available for child support and two children, with the court applying all three tiers.

• First $7,000: $7,000 x 25% = $1,750.
• From $7,000 to $12,500: $5,500 x 20% = $1,100.
• Above $12,500: $2,500 x 15% = $375.
• Total: $3,225 per month, which is $38,700 per year, an effective overall rate of 21.5 percent.

Compare the alternative. A straight 25 percent on the full $15,000 would be $3,750, so the tiers trim about $525 a month in this example, and only when the court chooses to apply them. That comparison line renders with every calculator result.

What counts as income at this level

High income cases turn on the income number more than the percentages. Gross income from all sources counts, including wages, bonuses, commissions, and earnings that never touch a W-2.^[4] Large one-time payments generally count as income as well.

Business owners face added layers, because courts can look past the salary line at what the business retains and why. If an earlier support order exists, that obligation adjusts the income before the tiers run, which pulls dollars out of the top band first. Both issues are exactly where these cases get won and lost.

Is there a cap on child support in Wisconsin?

No. The code requires the payer's full income available for child support to be considered, and the tiers reduce the rate on higher income rather than capping the obligation. What high earners get is a structure, not a ceiling.

Courts can also redirect part of a large support amount instead of reducing it. Wisconsin law lets a court set aside a portion of support in a separate fund or trust for the children's support, education, and welfare,^[5] and that option comes up most in exactly these cases.

What this estimate leaves out

Your result assumes the court applies every tier, which is never guaranteed. The court handles several other pieces separately too.

• The court's discretion. A judge can stay on the standard percentages for every dollar, and the record you build shapes that choice.
• Placement combinations. Shared, split, and combined structures blend with the tiers case by case, so a standalone tier number will not match those orders.
• Medical support and variable costs. Courts assign health insurance responsibility and cost decisions separately from this number.
• The order itself. Deviations run in either direction on request with written findings, and only a court sets, approves, or changes support.
