Fixed deposit rates in Brazil (2026)
Brazil's term deposit is the CDB, usually priced as a percentage of the CDI, which tracks the Selic (13.75% since 16 September 2026). Large banks pay about 100% of the CDI: Itaú and Bradesco do not publish a single CDB rate on their sites (check your offer in each bank's app), while BV advertises CDBs from 100% of the CDI, including 110% of the CDI on CDB Renda BV. That works out to roughly 13.6%–15% a year.
At around 14%, the fixed-deposit rate in Brazil is very high in nominal terms - but rates this large usually track higher local inflation, so your real, after-inflation return can be far smaller than the headline suggests.
Reference figures, ~2026. FD interest is often taxable and rates vary by bank and tenure - verify the current rate before depositing.
Worked example
For every R$ 50.000 deposited at 14.00% for 5 years (quarterly compounding):
- Maturity value: R$ 99.489
- Interest earned: R$ 49.489
Scale to your deposit amount. Longer tenures and higher rates grow the maturity value; compare banks before locking in.
How to get the best fixed-deposit return in Brazil
- Compare several banks - smaller and digital banks often pay more than the big high-street names.
- Ladder your deposits across different tenures so some matures regularly and you can reinvest at new rates.
- Check how often interest compounds; more frequent compounding grows the maturity value.
- Factor in tax on the interest, and compare against short-term government bills or bonds.
A named-bank rate check: Itaú and Bradesco (2026)
Itaú and Bradesco describe their CDBs as paying a percentage of the CDI without publishing a single rate (check on each bank's site), while BV advertises CDBs from 100% of the CDI, including 110% of the CDI on CDB Renda BV (rates as of 7 August 2026 on bv.com.br). The Copom cut the Selic by 0.25 percentage points to 13.75% a year on 16 September 2026, its fifth consecutive cut, and the CDI runs just below the Selic. A CDB paying 100%–110% of the CDI therefore yields roughly 13.6%–15% a year before income tax. Because the return is linked to the CDI, it rises or falls with each Selic decision unless you buy a fixed-rate (prefixado) CDB.
Frequently Asked Questions
How is FD maturity calculated in Brazil?
Maturity = P × (1 + r/4)^(4n) for quarterly compounding, where P is the deposit, r the annual rate and n the years. fin·calc uses this standard method.
What is the current FD rate in Brazil?
As a 2026 reference, fixed-deposit rates are around 14% per year, varying by bank and tenure. Brazil's term deposit is the CDB, usually priced as a percentage of the CDI, which tracks the Selic (13.75% since 16 September 2026). Large banks pay about 100% of the CDI: Itaú and Bradesco do not publish a single CDB rate on their sites (check your offer in each bank's app), while BV advertises CDBs from 100% of the CDI, including 110% of the CDI on CDB Renda BV. That works out to roughly 13.6%–15% a year.
Is FD interest taxable in Brazil?
Banks withhold income tax on CDB earnings at regressive rates by holding period: 22.5% up to 180 days, 20% for 181–360 days, 17.5% for 361–720 days and 15% beyond 720 days, with IOF also charged on redemptions within 30 days.
Is a fixed deposit safe in Brazil?
Fixed deposits carry no market risk. The Fundo Garantidor de Créditos (FGC) covers CDBs up to R$ 250,000 per CPF per financial institution or conglomerate, subject to an overall cap of R$ 1 million per CPF in any four-year period. They trade higher safety for lower long-term returns than equities.
Should I choose a fixed deposit or invest instead in Brazil?
A fixed deposit gives a guaranteed return and suits money you cannot afford to risk. Investing targets higher long-term growth but can fall in value. Many people keep an FD for safety and invest separately for growth.
How much does a 1-year CDB pay in Brazil now?
BV advertises CDBs from 100% of the CDI, including 110% of the CDI on CDB Renda BV; Itaú and Bradesco quote a percentage of the CDI in their own apps. With the Selic at 13.75% since 16 September 2026, that is roughly 13.6%–15% a year before tax.
How is CDB interest taxed, and is it protected?
Income tax is withheld on a regressive scale: 22.5% up to 180 days, 20% for 181–360 days, 17.5% for 361–720 days and 15% after 720 days. The FGC guarantees up to R$ 250,000 per CPF per institution, with a cap of R$ 1 million every four years.
