Savings vs. Fixed Income: The Real Comparison

Discover exactly how much return rate you are leaving on the table by keeping your money in a traditional savings account instead of switching to safe fixed income options (such as CDB (bank certificate of deposit) 100% CDI (interbank rate) and Selic Treasury rate).

Savings vs. Fixed Income: Where Does Your Money Grow Faster?

A traditional savings account is the most traditional investment in Brazil due to its simplicity and ease of access. However, its return rate is limited by law and, in most cases, it yields less than the official inflation rate or low-risk investments with FGC (Credit Guarantee Fund) guarantee.

How does the savings account return rate work?

The savings return rate is defined by two rules established according to the Selic rate:

The TR is usually zero or very close to zero, making the real return rate of savings very low in times of medium and long-term inflation.

Advantages of Fixed Income (CDB (bank certificate of deposit) 100% CDI (interbank rate))

A CDB (bank certificate of deposit) that pays 100% of the CDI (interbank rate) yields almost exactly the basic interest rate (Selic rate). Even with the charge of regressive Income Tax (which varies from 22.5% to 15% of the yield), the final net result of Fixed Income surpasses savings in almost 100% of normal economic scenarios in Brazil.

Frequently Asked Questions (FAQ)

No. Although savings are exempt from IR and CDB (bank certificate of deposit)s are not, the gross yield of CDB (bank certificate of deposit) (which follows the CDI (interbank rate)) is so superior to that of savings that, even after deducting the tax at redemption, the final net balance of CDB (bank certificate of deposit) remains much higher. This calculator deducts IR accurately to demonstrate this net difference.

The Reference Rate (TR) is a rate calculated by the Central Bank that serves as a financial index (adjustment of the FGTS (Severance Fund) balance, savings, and real estate financing). It is linked to the interest rate practiced by banks and only becomes positive when the Selic rate market exceeds the threshold of approximately 8.5% p.a. At low interest rates, the TR is zero.

Yes. The CDB (bank certificate of deposit) with daily liquidity is one of the main recommendations for an emergency reserve in Brazil. It combines a higher yield than savings (usually 100% of the CDI (interbank rate)), security covered by the FGC, and the possibility of immediate redemption at any time on business days or even on weekends and holidays (depending on the issuing bank).
