Since 2012, savings use two rules: if Selic > 8.5% p.a. → 0.5%/month + TR; if Selic ≤ 8.5% p.a. → 70% of Selic/month + TR.
Savings Account Yield Calculator (Poupança)
Simulate Brazilian savings account returns with 2025 TR + Selic rules.
How savings account yield is calculated in Brazil and its two rules.
Brazilian savings accounts (poupança) earn differently depending on the Selic rate. When Selic is above 8.5% per year, savings earn 0.5% per month plus TR. When Selic is at or below 8.5% per year, savings earn 70% of the Selic rate plus TR. Savings returns are fully tax-exempt for individuals. This makes them competitive for short-term and small-amount reserves, though CDB and Tesouro Direto generally offer better returns.
