Interest = Principal × Rate% × Time
Simple Interest = Principal × Annual Rate % × Time (years) ÷ 100. Compound Interest Amount = Principal × (1 + Rate ÷ (100 × n))^(n × t) − Principal, where n = compounding periods per year.
* Ejemplo: $1,000 at 5% for 2 years → $100 interest

Multiply $10,000 by 0.05, which equals $500 annual interest.
