About this calculator
The LCI × CDB calculator is a useful tool for investors who want to compare the returns of two popular investment products in Brazil: LCI (Real Estate Credit Letter) and CDB (Bank Deposit Certificate).
The formula behind the calculator is straightforward: LCI equivalent = CDB × (1 − IR), where IR represents the income tax rate. This means that, to compare the two investments, it is necessary to discount the income tax from the CDB.
The calculator is useful in real-life scenarios, such as when an investor needs to decide between investing their money in an LCI or a CDB. For example, if an investor has R$ 10,000.00 to invest and needs to choose between an LCI with a 10% annual return and a CDB with a 12% annual return, the calculator can help determine which is the better investment.
It is essential to be cautious when using the calculator, as the income tax rate can vary depending on the investor's situation. Additionally, it is crucial to consider other factors, such as the investment risk and liquidity, before making a decision.
