Simple Interest Formula
SI = (P × R × T) ÷ 100
Interest is only earned on the initial principal. The interest amount stays strictly constant across every time period.
Compound Interest Formula
A = P × (1 + R / (n × 100))^(n × T)
Interest generates its own interest over each compounding cycle (n). Wealth grows exponentially rather than linearly.
