Update – Version 9.1 of the Child Support Calculator released
January 6, 2015 (see **Important notice below)

The enhanced Excel™ Child Support calculators, updated releases of Version 9.1, are now available for download and public use. To access the calculators, click the green icon below, "downloadable Excel Calculators.”

The Excel calculators are updated as design changes, enhancements and required statutory amendments are completed.  Please visit this site periodically to check for updates to the calculators and download the updated version.

Annual Notice:  Pursuant to O.C.G.A. §19-6-53(a)(3)(B)(iv), the Georgia Commission on Child Support has the statutory responsibility to update formulas used to calculate applicable self-employment tax adjustments as related changes occur in the federal tax laws.  This update is made each year at the beginning of the month of January, and applies to Line 3 of Schedule B.  It is recommended that you download the electronic calculators in January of each year to ensure you are using an electronic worksheet that includes this statutory adjustment.

Version 9.0 of the calculators and versions released on or after July 1, 2014, includes statutory changes required by SB 282, which was enacted during the 2014 legislative session of the Georgia General Assembly. Specifically, changes were made to income included for purposes of calculating Gross Income in §19-6-15(f)(1)(A), and to who may request a Low Income Deviation in O.C.G.A. §19-6-15(i)(2)(B).

Download Excel Worksheet(Includes: Paper and Pen EZ short worksheet)

To access Georgia’s Excel child support calculators, click the “Downloadable Excel Calculators” green icon. The Excel child support calculators will run using Microsoft Excel, version 2007 or later, for the PC; and Microsoft Excel 2004 and 2011 for the Mac. After clicking the green icon, another web page will display from which you may download the Excel calculator of choice by clicking one of the three flags. The first two flags (green and yellow) allow access to the electronic versions of the Excel calculators, while the purple flag allows access to the pen and paper EZ Worksheet. The two downloadable Excel electronic calculators include built-in formulae for calculations and permits printing of the forms. All of these calculators are accessed via the Internet for download and should be saved to a hard drive, jump or thumb drive, disk or CD-ROM, where they can later be transported to another computer or accessed as necessary.

Important Notice

It has come to our attention that several websites are hosting “calculators” to estimate Georgia child support. Please be cautious if using these calculators. In a simple test, one calculator’s monthly support was off by $100, and another was off by $990! The only tools the public should use are those promulgated by the Georgia Commission on Child Support and found on the Commission website, unless they are only trying to get a general idea of what their child support might be.

We do wish to thank those whose web sites provide accurate information about Georgia child support and provide a link to the official calculators.
