Verified historical judgment interest rate lookup

Choose one of 21 reviewed state series and a date to retrieve the recorded annual value, effective period, branch warning, official source, and downloadable history. The tool refuses unsupported dates and documented gaps rather than substituting today’s rate.

Why a historical lookup matters

A current percentage is often the wrong answer for an older judgment. Some states select a rate by entry month or year; others publish quarterly, semiannual, or annual schedules that can reset while a balance remains unpaid. This tool searches the stored official history using the date meaning shown for each series. It never applies a later value retroactively.

What this tool does—and does not decide

• It identifies a recorded period rate. The result includes the period start, official source, full rate page, and CSV history.
• It does not calculate a payoff. Accrual date, principal, interest-bearing costs, compounding, partial payments, and end-date treatment remain separate questions.
• It does not choose a legal branch. A contract, claim type, judgment size, debtor category, or another statute can supply a different rate.
• It fails closed. Dates before the verified history, after source-aware coverage, or inside a documented publication gap are rejected instead of estimated.

Why only these 21 series are released

A long table alone is not enough. Every released series has reviewed official history, a precise interpretation for the date input, a source-aware end boundary, and branch language that prevents a historical observation from posing as a complete payoff calculation. Other states remain available as current references and will enter this lookup only when those same checks pass.
