Child Support Worksheet A or B:
Use the information from each of your Sworn Financial Statements to complete the appropriate
worksheet. You have two options to complete the worksheet.
Automatic Calculation Option: New child support guidelines became effective on January 1, 2014.
To access the software for electronically calculating child support based on the new guidelines, go to
www.courts.state.co.us – “Calculate Child Support/Maintenance” (you can also find a link to the
new software at the top of the “Modify Child Support” page). If you are trying to calculate retroactive
child support that was ORDERED prior to January 1, 2014, you will need to use the guidelines that
were in effect at that time. You can also access the old Excel electronic worksheet (JDF 1820E).
Manual Calculation Option: Each worksheet is available in a MANUAL “M” format; you will need to
obtain and calculate the Child Support Guidelines to determine your child support if you select this
format. If you wish to use the Manual Worksheets, please review Instructions for Completing
Worksheets A & B Manually (JDF 1822).
Worksheet A (JDF 1820M): Sole Physical Care. Physical Care for 273 nights or more per year.
If one or more of your children spends at least 273 nights with one parent they are considered to
have a primary home with that parent.
Worksheet B (JDF 1821M): Shared Physical Care. If one or more of your children spends more
than 92 nights per year with each parent, they are considered to have two homes (one at your
residence and one at the other parent’s residence).
