Child Support Guidelines
Theory, and Practice

Guideline Economics offers an alternative to the Income Shares and Percentage of Obligor Income methods of calculating child support, commonly used in U.S. states and many countries. Our method is based upon the actual costs of children and sound economics.
     We also feature sophisticated calculations of deviations to the child support presumptive awards that are currently in use.
     This site provides a wide array of information, research, and products on the many methods of calculating child support and correctly calculating deviations.


Primer on Child Support Deviations
Child support guideline awards are not written in stone. Whether you are a noncustodial or custodial parent you have the right to ask the court to make an award that differs from the presumptive amount if your case warrants. Read more (PDF).

The Law And Economics Of Child Support Payments
This book is a collection of papers by R. M. Rogers, Sanford Braver, and others and provides important citation material.
