Is Wisconsin judgment interest simple or compound, and when does it start?
The statute and official table establish the entry-date rate, but StatuteRates does not enable a Wisconsin payoff calculator because calculator-grade day count, compounding, partial-payment allocation, and every superseding branch have not been fully verified. The judgment-entry date selects the controlling half-year benchmark: for January through June entries, use the H.15 bank prime rate in effect on the immediately preceding January 1; for July through December entries, use the rate in effect on the immediately preceding July 1. Add one percentage point. That selected annual rate remains fixed from entry until the judgment is paid.
