Comparison: CDB vs LCI/LCA vs Savings

CDB, LCI, LCA and savings accounts are popular fixed-income investments in Brazil with different tax treatment.

How we calculate

CDB is taxed on a regressive scale (22.5% to 15%). LCI, LCA and savings are tax-exempt for individuals in Brazil.

Each option projects gross value via compound interest; CDB has regressive tax deducted from the return.

Compara o valor líquido final de CDB (tributado), LCI/LCA e poupança (isentas de IR)

A 100% CDI CDB may net less than a 90% CDI LCI over the same term, because LCI pays no income tax.

Compare the final net amount of each option — it already accounts for taxation (or exemption).

CDI rate and the savings rule use reference values that may be outdated.

Why are LCI and LCA tax-exempt?

They fund the real estate (LCI) and agribusiness (LCA) sectors, and Brazil exempts individuals from income tax on them as an incentive.
