💰 Profit Calculation Examples

Term deposit (5.8% annually):

• Profit after 2 years: 25,000 × (1.058)² = 27,981 PLN

ROR bonds (inflation 3.2% + 1.0% margin = 4.2%):

• Profit after 2 years: 25,000 × (1.042)² = 27,155 PLN
• Net profit: 2,155 PLN - 19% tax = 1,745 PLN

Verdict: CD wins with low inflation

Scenario 2: 10,000 PLN investment for 12 months
