Calculate how much your money can earn in CDB, LCI, LCA, or investments linked to CDI, IPCA, or fixed rate. Compare gross earnings, income tax, and net amount.

The CDB (Certificado de Depósito Bancário) is a debt security issued by banks to raise funds. In practice, you "lend" your money to the financial institution in exchange for interest after a certain period.
The LCI (Letras de Crédito Imobiliário) and LCA (Letras de Crédito do Agronegócio) are securities issued to finance the real estate and agribusiness sectors. The big difference between LCI and LCA and CDB is the exemption from Income Tax for individuals. Because of this, LCI/LCA nominal rates, slightly lower, often surpass CDB with higher rates. This calculator performs exactly this comparative calculation of net equivalence for you to make the best decision.
The main difference lies in the collection of Income Tax. While CDB has IR withheld at source following the regressive table (from 22.5% to 15% on profits), LCI is totally exempt from income tax for individuals. To compare both fairly, it is necessary to calculate the net yield. For example, in a 1-year term (17.5% IR), an LCI that pays 90% of CDI is equivalent to a taxable CDB of approximately 109% of CDI.
Income Tax on taxable fixed income investments only applies to the yield (profit) of the investment and decreases as the time the money remains invested increases:
The CDI (Certificado de Depósito Interbancário) is a rate that reflects the average cost of daily loans that banks make to each other to close the day's accounts. It closely follows the basic interest rate of the Brazilian economy (the Selic rate), usually 0.10 percentage points below it.
