Savings Return Calculator 2025: How to Calculate
Learn how to calculate Brazilian savings returns in 2025. Currently yields 7.35% annually. Free online calculator and complete comparison guide.
Savings accounts remain Brazil’s most popular investment in 2025, despite low returns. Currently, they yield 70% of the Selic rate when it’s above 8.5% annually, which means approximately 7.35% per year with the Selic at 10.5%.
For those seeking total security and daily liquidity, understanding exactly how to calculate savings returns is fundamental before investing.
How savings accounts work in 2025
Brazilian savings accounts follow specific rules that determine their profitability. The return is not fixed — it varies according to the Selic rate set by the Central Bank.
Compensation rules
Savings account compensation in 2025 follows this official rule:
- Selic above 8.5% annually: return of 70% of Selic + TR
- Selic equal to or below 8.5% annually: return of 8.5% annually + TR
With the current Selic at 10.5% annually, savings accounts yield 7.35% annually + TR.
Selic rate and TR
The Reference Rate (TR) has been at zero since 2017 and should remain so in 2025. This means the effective return of savings accounts is only 70% of the Selic.
Example: With Selic at 10.5% annually, savings accounts yield 10.5% × 0.70 = 7.35% annually (approximately 0.57% monthly)
Calculating savings returns
Calculating savings returns follows a specific formula and depends on the account anniversary.
Official formula
The formula to calculate monthly savings returns is:
Return = Applied Amount × (Monthly Rate ÷ 100)
Where the current monthly rate is approximately 0.57% (7.35% ÷ 12 months).
Account anniversary
Returns are only credited on the monthly anniversary of the investment. If you deposit on the 15th, returns will be credited every 15th of each month.
Important anniversary rules:
- Money withdrawn before the anniversary loses all returns for the month
- For months with fewer than 31 days, the anniversary adjusts automatically
- There are no proportional daily returns
Example: R$ 10,000 invested yields R$ 57 per month (R$ 10,000 × 0.0057). In 12 months: R$ 684 gross return.

Savings vs other investments
Comparing savings accounts with other fixed income options available in 2025.
CDB (Bank Certificates of Deposit)
CDBs from major banks typically yield between 90% to 110% of CDI. With CDI close to Selic (10.5%), a CDB paying 100% of CDI yields 10.5% annually.
Main differences:
- CDB: 10.5% annually (100% CDI)
- Savings: 7.35% annually (70% of Selic)
- Difference: 3.15 percentage points in favor of CDB
Government Bonds (Tesouro Direto)
The Tesouro Selic 2031 tracks the basic interest rate and offers returns superior to savings accounts.
| Investment | Annual Return | IR (up to 180 days) | IR (over 720 days) |
|---|---|---|---|
| Savings | 7.35% | Exempt | Exempt |
| Tesouro Selic | 10.5% | 22.5% | 15% |
| CDB (100% CDI) | 10.5% | 22.5% | 15% |
Important: Savings accounts are exempt from Income Tax, but other investments have regressive taxation.
Advantages and disadvantages
Savings advantages
- Total Income Tax exemption
- Immediate liquidity (can withdraw anytime)

Savings disadvantages
