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.
