Brazil judicial monetary correction: civil regime after Law 14,905
Correcting a civil debt by court decision is not a matter of multiplying the amount by a single index from start to finish: the regime changed rate on 08/30/2024 with Law 14,905/2024, and the STJ set in Theme 1,368 which rate applies to the period before that. This calculator segments the period automatically at the mark date and applies the correct regime to each stretch, adding interest and correction at the end.
The cut on 08/30/2024 is not the calculator choice: it is Law 14,905/2024 effective date, hardcoded as a fixed mark.
The ADC 58 (STF) modulation uses the filing date, not the event date, as the second mark separating the pre-filing phase from the judicial phase.
The payment cuts the segments at its own competency and abates accrued interest first, only then the corrected principal (CC art. 354); none of the regimes here compound interest on interest.
Full SELIC until 29/08/2024 (STJ Tema 1.368) and, from 30/08/2024, IPCA for correction plus the Legal Rate for interest (Law 14.905/2024).
Because Law 14,905/2024 amended CC arts. 389 and 406 starting that date, separating monetary correction (IPCA) from interest (Legal Rate); before that, the STJ had set in Theme 1,368 that full SELIC, already including interest, was the rate under the old art. 406.
Not exactly: the labor preset adds its own mark, the ADC 58 modulation on 08/30/2021, which splits the pre-filing phase (IPCA-E) from the judicial phase (exclusive SELIC), in addition to the same general 08/30/2024 mark from Law 14,905/2024 that also applies to civil cases.
Monetary correction runs from the arbitration date of the amount, per STJ Súmula 362; default interest runs from the harmful event, per STJ Súmula 54. The two dates differ, and the calculator handles each in its own segment.
No: CC art. 354 requires imputing each payment first to accrued interest and only then to the corrected principal. The calculator cuts the period at the payment date and follows that order, without compounding interest on interest.
