Frequently Asked Questions

What is CDI?

CDI (Certificado de Depósito Interbancário) is a benchmark interest rate used in Brazil for interbank loans and as a reference for many financial investments, similar to the SELIC rate.

How is the CDI calculation performed?

The calculator uses compound interest formula: Final Amount = Initial Investment × (1 + (CDI Rate/100))^(Period in years). For days/months, it converts to years. Tax is applied to the gross profit: Net Profit = Gross Profit × (1 - Tax Rate/100).

What tax rate should I use?

Use the applicable tax rate for your investment type (e.g., income tax on financial investments in Brazil). If unsure, consult a financial advisor or use 15% as a common rate for illustration.

Can I calculate for different period units?

Yes, you can select days, months, or years. The calculator automatically converts to years for accurate compound interest calculations.
