Understanding Compound Interest

Compound interest is the interest calculated on the initial principal and also on the accumulated interest from previous periods. It's the foundation of wealth building through investments.

Formula

Where A = final amount, P = principal, r = annual interest rate (decimal), n = compounding frequency per year, t = time in years

Example Calculation

Scenario:

Investment of ₹1,00,000 for 5 years at 8% p.a., compounded quarterly

Calculation:

A = 1,00,000 × (1 + 0.08/4)^(4×5)

Result:

₹1,48,594.74 (Interest earned: ₹48,594.74)

Key Points

  • More frequent compounding (monthly vs. annual) leads to higher returns
  • The power of compounding increases significantly over longer time periods
  • Even small differences in interest rates compound to large differences over time
  • Time is the most powerful factor in compound interest calculations
