Ten percent is a rebuttable support presumption

A contesting party may prove that applying another interest amount produces the correct result; the ordinary annual judgment rate is published separately.

Kansas arrears calculator FAQs
Is 10% always conclusive?
No. It is a statutory presumption that may be rebutted with proof of the correct amount.
Why is the general judgment rate different?
Kansas publishes a variable general rate each July, while subsection (e) separately addresses support judgments.
Does this tool compound interest?
No, it uses a simple-interest estimate.
Can payments change the result?
Yes. Dates and allocation of payments materially affect an actual ledger.
Should I include fees?
Use only verified support principal unless the ledger legally includes another judgment amount.
Is this an official payoff?
No. Obtain a current court or agency ledger.
