Child Support Calculator

Empowering Families with Information

We built this site to demystify the financial side of co-parenting. Our goal is to give parents a reliable starting point for understanding potential child support obligations before they walk into a lawyer's office.

Our Purpose

Navigating the legal and financial complexities of family separation is inherently stressful. One of the most significant sources of anxiety is uncertainty regarding financial obligations. Child Support Calculations was created to bridge that information gap, offering an accessible, free and straightforward tool for estimating support based on published statutory guidelines.

By providing a transparent look at how different factors—like income, custody arrangements, and state models—affect support calculations, we hope to foster more informed and productive discussions between co-parents and their legal representatives.

Accuracy First

We continuously monitor state guideline updates to ensure our estimation formulas reflect current standards.

Privacy Focused

All calculations happen locally in your browser. We never store, track, or share your financial data.

Accessible to All

We believe basic legal and financial estimation tools should be free and easy to use for everyone.

Important Disclaimer

While we are deeply committed to getting these numbers right, this tool is not a substitute for legal advice. The numbers produced are baseline estimates. Actual court-ordered support can vary significantly based on mandatory add-ons (like health insurance or childcare), tax considerations, and judicial discretion. Always consult a qualified family law attorney before making legal or financial decisions.
