About DocketMath

Every calculator follows the same process: you enter case details, we apply jurisdiction-specific rules, perform the calculations, and show you court-ready results with citations. All inputs are validated before calculations run to ensure accuracy.

All calculations are automatically tested against expected outputs. We test core functions like interest calculations, date arithmetic, business day counting, and proration to ensure they handle edge cases correctly.

We use a research system to source jurisdiction-specific statutes, rates, and rules. Every rule goes through multiple validation checks to catch errors and ensure accuracy. Rules include statute citations with URLs to official legal sources.

Every calculator includes a "Report an Issue" button. Reports are reviewed and fed back into our validation system. We also monitor calculation success rates and error patterns to proactively catch issues.

Rules are validated periodically and updated when statutes change or errors are found. The system monitors for broken statute links and flags rules that need review.

Currently 50+ jurisdictions across the United States, with plans to expand globally.
