Winning the Mega-Sena lottery is a dream for many Brazilians. With prizes that can transform lives, it's no wonder so many people invest in the hope of one day being drawn. Recently, the accumulated prize reached the impressive mark of R$37 million. But a common question that arises is: how much would this amount yield if deposited in a savings account? Let's explore this question in detail.
How Savings Works
Savings accounts are one of the most traditional forms of investment in Brazil. Their popularity stems from their security and ease of access, as well as the fact that they don't require extensive financial knowledge to use. Currently, the return on savings is determined as follows:
- When the Selic rate is above 8.5% per year, the savings account yield is 0.5% per month + TR (Reference Rate).
- When the Selic rate is equal to or below 8.5% per year, the savings account yield is 70% of the Selic rate + TR.
For the sake of simplicity in this example, let's consider the TR (reference rate) to be zero, since it has been zero for an extended period.
Monthly Income
Assuming the Selic rate is above 8.5% per year (current scenario in Brazil in 2024), savings accounts yield approximately 0.5% per month.
With that in mind, let's calculate how much the R$ 37 million would yield in savings in one month.

Calculation
Monthly income can be calculated using the formula:
Therefore, by depositing R$ 37 million into savings, the amount would yield R$ 185,000 in one month.
Annual income
To understand the long-term impact, it's helpful to project the annual return. Using the same reasoning, but now considering the effect of compound interest, where each monthly return is reinvested in savings.
Calculation
The formula for the accumulated amount with compound interest is:
Therefore, at the end of a year, the R$ 37 million would become approximately R$ 39,283,000, generating an income of R$ 2,283,000 during the period.
Simplicity and security
Although savings accounts offer security and convenience, they are not the most profitable investment option available. With a significant amount like R$ 37 million, considering other investment options such as Certificates of Deposit (CDBs), Treasury Direct, real estate funds, and stocks can provide higher returns.
However, for those who prefer the simplicity and security of saving, knowing that the Mega-Sena prize would yield R$185,000 per month or approximately R$2,283,000 per year is valuable information. This amount is enough to guarantee a comfortable life without financial worries, provided it is well managed.
