About this calculator
The TR annual approximation calculator estimates Brazil's Reference Rate (TR) based on the Selic. The TR is calculated by multiplying the current Selic rate by 0.02. This formula serves as a quick approximation, as the official TR is defined monthly by the Central Bank but does not directly depend on the Selic.
To use the tool, input the current or estimated Selic rate. The calculator will apply the formula TR = Selic × 0.02 and display the result. It's useful for quick comparisons in contexts like loans, investments, or cost analysis, but it does not replace the Central Bank's official data.
Note: The actual TR may vary due to monetary policies and government adjustments. The Selic-based approximation is only a guideline. For critical financial decisions, always refer to the updated tables from Brazil's Central Bank.
Frequently asked questions
What is TR and how does it relate to the Selic?
TR (Reference Rate) is a rate used in Brazilian interest calculations. The Selic is the country's basic interest rate. The approximate TR is calculated as 2% of the Selic, but the Central Bank may adjust it independently.
When to use this TR approximation calculator?
Use it for quick cost estimates of loans, return comparisons, or financial planning. It does not replace the Central Bank's official data.
Why might the official TR differ from the Selic-based approximation?
Because the official TR is set monthly by the government and may consider factors beyond the Selic, such as fiscal policies or market adjustments.
Does the calculator work with future or hypothetical Selic rates?
Yes, simply input any valid Selic value. The result will be an estimate based on that hypothetical rate.
