Retroactive Support Calculator

Support wasn't paid at the correct level for a period of time? Estimate the shortfall owed for that retroactive period.

Estimate only — not legal advice. Retroactive awards depend on the D.B.S. v. S.R.G. factors, not math alone.

⚖️

D.B.S. v. S.R.G.

The Supreme Court's leading case sets out the framework courts use to decide whether — and how far back — to order retroactive child support.

📅

The 3-Year Guideline

Retroactive awards typically don't go back more than about 3 years before effective notice was given, absent blameworthy conduct by the payor.

🔔

Effective Notice

Simply raising the issue of updated income or support — not necessarily filing in court — can start the retroactive clock in some cases.

📊

Income Disclosure

Retroactive claims often arise from a payor's undisclosed income increases. Full financial disclosure is essential in these cases.
