Illinois Maintenance Calculator

Temporary maintenance may be awarded during the divorce proceeding to address immediate financial needs. Post-divorce maintenance is governed by 750 ILCS 5/504, which establishes presumptive net-income formulas, duration schedules, and deviation factors for final awards. In Illinois, maintenance is designed to address financial disparity between spouses after divorce. A spouse may qualify for maintenance when the statutory analysis demonstrates a need for support and the circumstances justify an award. Courts examine income, property distribution, earning capacity, future opportunities, and the standard of living established during the marriage. Qualification is determined under the statutory factors rather than income disparity alone.

Illinois generally applies a guideline formula equal to 33.33% of the payer's net income minus 25% of the recipient's net income. The resulting maintenance amount, when combined with the recipient's net income, cannot exceed 40% of the parties' combined net income. Courts may deviate from the guideline after considering statutory factors and explaining the reasons for deviation. Our calculator uses net income and the formula: Estimated maintenance = 33.33% of payer net income minus 25% of recipient net income, subject to the rule that recipient income plus maintenance cannot exceed 40% of combined net income.. Illinois guideline maintenance is governed by 750 ILCS 5/504 and relies on net income rather than gross income. Duration is generally determined using statutory marriage-length multipliers, although courts may deviate when justified by statutory factors.

Because Illinois uses equitable distribution rules, property division under 750 ILCS 5/504 (Illinois Marriage and Dissolution of Marriage Act) may reduce ongoing maintenance need. Guideline maintenance is based primarily on net income rather than gross income..

Courts balance rehabilitation goals with preservation of economic fairness. Duration guidelines: Maintenance duration is typically determined by statutory multipliers applied to the length of the marriage, with longer marriages supporting longer awards and some long-term marriages potentially justifying indefinite maintenance..

Illinois judges apply 750 ILCS 5/504 (Illinois Marriage and Dissolution of Marriage Act) and weigh multiple factors when setting maintenance. Illinois uses statutory maintenance guidelines that rely primarily on the parties' net incomes. For many cases, courts calculate maintenance using a formula established in 750 ILCS 5/504, while retaining authority to deviate when application of the guideline would be inappropriate. The statute also provides duration multipliers tied to the length of the marriage.

Income and earning capacity: Illinois courts evaluate income and property allocated to each spouse through the Illinois divorce process..
