LCI vs CDB Calculator

Compare a tax-exempt LCI with a taxed CDB using rates and term entered by you.

What this tool does

The LCI vs CDB calculator compares two Brazilian fixed-income products with different tax treatment. It estimates CDB with a simplified regressive tax and LCI as tax-exempt return, using the rates entered by the user.

The goal is to understand when a tax-exempt rate can compete with a taxed rate. The calculation does not replace product documents, liquidity rules, guarantees, institutional fees or professional advice.

How to use

  1. Enter amount and term.
  2. Type annual LCI and CDB rates.
  3. Compare estimated net result and difference.
