Credit Card Revolving Cost

Credit-card revolving credit explained

Revolving credit is the line that switches on automatically whenever you pay less than the full bill. It runs on monthly compound interest: debt(n) = debt(0) · (1 + i)^n. Before the CMN 2023 rule, rates ran past 400% per year. The new cap bars total charges from going over 100% of the original debt, so R$ 1,000 in the revolving line can never grow beyond R$ 2,000 across the contract. Once 30 days pass, the issuer has to move the balance into a fixed installment plan at a contractually defined rate.

Applications

This calculator helps you map out a worst-case financial emergency, weigh the revolving line against a CDC personal loan, and see what renegotiation under Law 14.181/2021 ("Superendividamento") actually does. The revolving line is the worst credit option in Brazil. Only reach for it when there's genuinely no alternative, and clear it as fast as you can.

FAQ

What is the legal cap on revolving interest? Since 2023, the CMN Resolution holds total charges (interest, fees, IOF) to 100% of the original debt amount.

How long does the revolving line last? Up to 30 days. After that, the issuer has to offer a fixed installment plan at a defined rate, normally lower than the revolving one.

What is the typical rate today? Somewhere around 10-15% per month in 2024-2026, depending on the issuer and your profile.

Can I renegotiate? Yes. Law 14.181/2021 ("Superendividamento") lets you renegotiate debt at Procon, and Serasa Limpa Nome runs periodic campaigns with discounts of up to 99%.
