Savings Account Returns: Understand How Your Money Grows
The savings account is historically Brazil’s most popular investment. Simple to open, tax-free for individuals, and protected by the Credit Guarantor Fund (FGC), it wins over millions of Brazilians seeking security for their money. But this popularity hides a silent trap: many people don’t know exactly how much their savings account earns — or whether that return is enough to at least preserve purchasing power over time.
Understanding the savings account remuneration rules isn’t a technical detail reserved for experts. It’s essential information for anyone who wants to make conscious financial decisions. After all, saving money in a product without understanding how it grows is like driving without looking at your dashboard: you might reach your destination, but without knowing if you’re on the right path.
In this article, we’ll explain clearly and accurately how savings account returns work, what its real advantages are, its important limitations, and what you should consider when comparing it to other options available in the market.
How Savings Account Returns Are Calculated
The savings account remuneration rule changed in 2012 and follows two distinct scenarios, defined based on the Selic rate — the basic interest rate of the Brazilian economy, established by the Monetary Policy Committee (Copom) of the Central Bank.
When Selic is above 8.5% per year
When Selic exceeds this threshold, the savings account earns 0.5% per month (equivalent to approximately 6.17% per year) plus the Referential Rate (TR). The TR is an index calculated by the Central Bank that, depending on the economic scenario, can be zero or a very low value. To find out the current TR value, consult directly the Central Bank of Brazil website.
When Selic is equal to or below 8.5% per year
In this scenario, the savings account earns 70% of Selic plus the TR. This rule was created precisely to prevent the savings account from becoming more advantageous than other fixed income investments in low-interest periods.
To know which scenario applies at the moment you’re reading this article, visit the Central Bank website and check the current Selic rate. This data changes at each Copom meeting, which occurs approximately every 45 days.
The Anniversary Date Question
A detail that many people don’t know about and that can make a practical difference: the savings account only earns on the anniversary date of the deposit, not daily. If you deposit money today and need to withdraw before one month passes, you won’t receive any return on that amount — it will sit without growing.
This means that:
- Deposits made on the 29th, 30th, or 31st have their anniversary on the 1st of the following month.
- If you withdraw before the anniversary, you lose all the period’s earnings.
- For those who use savings accounts as emergency reserves with frequent withdrawals, this characteristic can significantly reduce the real return received.
Real Advantages of Savings Accounts
Savings accounts have legitimate attributes that explain their popularity. It’s important to recognize them without exaggeration:
- Income Tax exemption for individuals: while other fixed income investments are subject to regressive taxation (from 22.5% to 15%, depending on the term), savings accounts don’t deduct income tax, which improves net returns in direct comparison.
- FGC protection: savings deposits are guaranteed by the Credit Guarantor Fund up to R$ 250,000 per CPF per financial institution, with a global limit of R$ 1 million per CPF every four years. This guarantee provides security for amounts within this ceiling.
- Immediate liquidity: money can be withdrawn at any time, although returns are only credited on the anniversary date.
- No fees or costs: there is no charge for administration fees, custody, or other expenses.
- Accessibility: anyone can open a savings account with no minimum required value at most institutions.
Limitations and Risks You Need to Know
Honesty demands we also discuss the other side of the coin. Savings accounts have concrete disadvantages worth noting:
- Risk of real loss to inflation: savings account returns don’t always exceed inflation as measured by the IPCA (Broad National Consumer Price Index). In scenarios of high inflation, it’s possible that money in a savings account will lose purchasing power over time, even with positive returns in nominal terms.

- Potentially lower returns than alternatives: in many scenarios, products like Selic Treasury, daily liquidity CDBs, and low-cost DI funds can offer net returns superior to savings accounts — even after IR deduction. This isn’t guaranteed, but it’s a relevant aspect to evaluate.
- Institutional credit risk: although FGC protection exists, the fund has limits and it’s important not to confuse the guarantee with complete absence of risk, especially for amounts above covered limits.
- The TR can be zero: in certain economic scenarios, the TR equals zero, which means the return consists only of the fixed portion (0.5% per month or 70% of Selic).
How to Calculate Savings Account Returns in Practice
To get a practical sense, see a simple example of how the calculation works — remembering that the numbers below are only illustrative for educational purposes:
Hypothetical example:
- Amount invested: R$ 10,000.00
- Scenario: Selic above 8.5% per year (0.5% per month + TR)
- Period: 12 complete months (with anniversaries respected)
- TR: considered zero for simplification
Approximate calculation:
- R$ 10,000 × (1.005)^12 ≈ R$ 10,616.78
- Gross return over the period: approximately R$ 616.78
- Income tax: zero (savings accounts are exempt for individuals)
- Net return: approximately R$ 616.78
Attention: this is merely an illustrative example. Actual returns will depend on the Selic rate in effect during each period, the TR value, and any withdrawals before the anniversary. Never take this number as a guaranteed projection.
Savings Account Versus Other Alternatives: A Comparative View
It’s common to see comparisons between savings accounts and other products. The table below organizes some general aspects — it’s not a recommendation, but a guide to help you ask the right questions before deciding:
| Characteristic | Savings Account | Selic Treasury | CDB (daily liquidity) |
|---|---|---|---|
| Income Tax | Exempt (individuals) | Yes (15% to 22.5%) | Yes (15% to 22.5%) |
| FGC Guarantee | Yes | No (National Treasury guarantee) | Yes (within limits) |
| Liquidity | Immediate (no returns before anniversary) | D+1 (withdrawal in 1 business day) | Immediate (generally) |
| Cost | No fees | B3 custody fee (check current value) | Varies by bank/brokerage |
| Potential Return* | Limited by Selic rule | Close to gross Selic | Varies (% of CDI) |
*Potential return is not guaranteed return. Always verify current conditions at institutions and official sources.

What to Check Before Leaving Your Money in Savings
If you’re evaluating whether a savings account is the right place for your money right now, here are the points worth checking:
- Check the current Selic on the Central Bank website (bcb.gov.br) and understand which return scenario the savings account is in.
- Compare with accumulated IPCA from the last 12 months, available at IBGE (ibge.gov.br), to know whether the savings account return is preserving or losing to inflation.
- Evaluate what purpose the money is saved for. For short-term emergency reserves, the liquidity of savings accounts can be convenient. For medium and long-term goals, other alternatives may be more suitable — but this depends on your profile and situation.
- Check your total deposits. If you have amounts exceeding FGC limits at a single institution, consider diversifying across different financial institutions.
- Consider the opportunity cost. Simple and powerful question: “Is there another equally safe and accessible product that would deliver me higher net returns?” The answer can vary depending on the economic moment.
Conclusion: Knowledge Is the First Step
The savings account is neither villain nor hero of personal finances. It’s a product with specific characteristics — real advantages in simplicity, tax exemption, and FGC protection — but also with important limitations, especially regarding returns relative to inflation and available market alternatives.
Most importantly, you need to understand exactly how it works before deciding to use it. Well-informed financial decisions, even the simplest ones, make accumulated differences over time. There is no single answer for everyone: what makes sense for one person may not work for another, depending on goals, timeframe, risk tolerance, and financial situation.
