About Legal calculators
Legal calculators put numbers on common legal situations: procedural deadlines in days, statutory (legal) interest, child support, and court fees. They give an informative estimate to help you prepare — not legal advice.
Frequently asked questions
How is statutory interest calculated?
Legal interest applies the official reference rate to the amount owed over the period of delay, giving the interest due on a late payment or a court-ordered sum.
How do I count a legal deadline?
Enter the starting event and the number of days; the calculator counts them according to the rules for calendar or working days and shows the final date.
How is child support estimated?
Child support is usually a share of the paying parent’s income that rises with the number of children; the calculator gives an informative estimate, while the final amount is set by agreement or a court.
What is the statute of limitations?
It is the period within which a claim can still be pursued; once it passes, the right to act is usually lost. The calculator counts the term from the starting event.
