Texas Child Support Arrears – Advanced Estimator

Sinkin Law – San Antonio, Texas

Estimate unpaid child support across multiple time periods, with interest.

Important: This tool gives a rough estimate under Texas law. It is not legal advice, does not create an attorney–client relationship, and is not an official audit. For an exact arrears calculation contact us at (800)932-6553.

Interest note: Texas arrears are calculated at 6% simple interest per year. We also show a compounded-growth view for perspective.

If you list specific missed months, this tool will calculate using those months instead of the date ranges above. When you switch this on, we’ll auto-fill all months from your ranges so you can edit/remove any.
