Savings Account Yield 2025: Complete Calculation Guide
Learn how to calculate your savings account returns in 2025. Understand the new rules, formulas, and compare with other investments. Free calculator.
Savings accounts remain the most traditional investment for Brazilians, but their 2025 yield is tied to specific rules that few fully understand. Understanding how to calculate exactly how much your investment will earn is essential for making better financial decisions.
With the Selic Rate at elevated levels, savings accounts operate under the new rule, which can offer different returns from the well-known 0.5% monthly rate. Let’s break down all aspects of the calculation.
How savings accounts work
Yield rules
Savings account returns are not fixed at 0.5% per month as many believe. Since 2012, there’s a dual rule that determines how much your investment will earn monthly.
The profitability depends directly on the Selic Rate level at the time of deposit. This rule was created to make savings accounts less attractive in high interest rate scenarios, encouraging other investments.
TR + interest
The total savings account return consists of two components:
- Taxa Referencial (TR - Reference Rate): currently at zero since 2017
- Interest payments: vary according to the current Selic
- Total return: TR + interest (applied monthly on the anniversary date)
Example: With TR at zero, savings account returns depend only on the interest payments defined by the Selic rule.
New savings account rule
When it yields 0.5%
Savings accounts yield 0.5% per month + TR when the Selic Rate is equal to or below 8.5% per year. This is the “traditional” rule that was in effect before 2012.
Considering TR at zero, the effective return is 0.5% monthly, equivalent to approximately 6.17% per year.
When it yields 70% of Selic
With Selic above 8.5% per year, savings accounts yield 70% of the Selic Rate + TR. This rule significantly reduces savings account attractiveness in high interest rate scenarios.
In 2025, with Selic projected between 10% and 12% per year, savings accounts will yield:
- Selic at 10% per year: savings yield 7% per year
- Selic at 11% per year: savings yield 7.7% per year
- Selic at 12% per year: savings yield 8.4% per year
How to calculate returns
Calculation formula
The formula varies according to the Selic scenario:
Selic ≤ 8.5% per year:
Return = Balance × (0.5% + TR)Selic > 8.5% per year:
Return = Balance × (70% of monthly Selic + TR)Savings anniversary
Returns are only credited on the anniversary date of the deposit. If you withdraw before, you lose all profitability for the period.
- Deposit on the 15th: returns credited every 15th
- Withdrawal on the 14th: lose the entire month’s return
- Multiple deposits: each has its own anniversary
Step-by-step example
Let’s calculate the return on R$ 10,000 invested in January 2025, considering Selic at 11% per year:
Monthly calculation:
- Annual Selic: 11%
- Monthly Selic: 11% ÷ 12 = 0.917% per month
- Savings return: 70% × 0.917% = 0.642% per month
- Return value: R$ 10,000 × 0.642% = R$ 64.20

Savings vs other investments
Comparison with CDI
In 2025, with high Selic rates, other investments easily outperform savings accounts:
| Investment | Estimated return | Taxation |
|---|---|---|
| Savings | 7.7% per year | Tax-free |
| CDB 100% CDI | 10.9% per year | 15% to 22.5% IRPF (income tax) |
| CDB 110% CDI | 12% per year | 15% to 22.5% IRPF |
| LCI/LCA 90% CDI | 9.8% per year | Tax-free |
Treasury Selic
Treasury Selic directly tracks the Selic Rate, offering superior returns compared to savings accounts:
- Profitability: 100% of Selic (vs 70% for savings)
- Liquidity: daily (vs monthly for savings)
- Taxation: 15% to 22.5% on gains
- Minimum investment: around R$ 100
Comparative example: With Selic at 11% per year, Treasury Selic yields 11% gross, while savings yield only 7.7%.

Different scenarios
Our calculator allows simulating various scenarios:
R$ 5,000 investment for 12 months:
| Selic Scenario | Savings return | Final value |
|---|---|---|
| 8% per year | R$ 308.50 | R$ 5,308.50 |
| 10% per year | R$ 350.00 | R$ 5,350.00 |
| 12% per year | R$ 420.00 | R$ 5,420.00 |
Monthly contributions
For those making monthly contributions, each deposit will have its own anniversary:
- Deposit on the 5th: yields every 5th
- Deposit on the 15th: yields every 15th
- Deposit on the 25th: yields every 25th
This can generate up to three different anniversary dates in the same savings account.
Advantages and disadvantages
Savings account advantages
- Total tax exemption on returns
- FGC guarantee up to R$ 250,000 per CPF and institution
- Simplicity: no technical knowledge required
- Immediate liquidity (loses period returns)
- No management or custody fees
Disadvantages in 2025
- Lower returns than other safe investments
- Loss of returns if withdrawn before anniversary
- Doesn’t fully track Selic increases
- Risk of losing to inflation in specific scenarios
When it’s worthwhile
Savings accounts still make sense for:
- Emergency fund with easy access
- Ultra-conservative profile prioritizing absolute security
- Small amounts where fees from other investments would be significant
- Those who don’t want to worry about maturity dates or withdrawals
Frequently Asked Questions
How is savings account return calculated in 2025?
Returns depend on the Selic Rate. If above 8.5% per year, savings yield 70% of Selic + TR. If equal to or below 8.5%, it yields 0.5% per month + TR. With TR at zero since 2017, only interest payments are applied.
When does money in savings accounts earn returns?
Returns are credited only on the deposit anniversary date, which occurs monthly. If you deposit on the 15th, money only earns returns every 15th. Withdrawals before the anniversary date cause loss of all returns for the period.
What is the current savings account return?
In 2025, with Selic projected between 10% and 12% per year, savings should yield between 7% and 8.4% per year. This value is well below investments like CDB, LCI/LCA and Treasury Selic, which more directly track rising interest rates.
Are savings accounts still worthwhile in 2025?
For emergency funds and ultra-conservative profiles, yes. However, those seeking profitability will find better options in CDB, LCI/LCA and Treasury Selic. Savings accounts lost attractiveness with the new rule and high interest rates.
How can I simulate my savings account return?
Use our free savings calculator. Enter the invested amount, time period and the tool will automatically calculate returns based on the current Selic rule, showing final value and monthly gains.
Can I withdraw from savings accounts at any time?
Yes, savings accounts have daily liquidity. However, if you withdraw before the monthly anniversary date, you lose all returns for the period. Therefore, plan withdrawals for after the anniversary if you want to maintain profitability.
Is there a limit on savings account amounts?
There’s no minimum or maximum limit for investing in savings accounts. The FGC guarantee covers up to R$ 250,000 per CPF and financial institution. Amounts above this limit have no government guarantee, but continue earning returns normally.
