How is it Calculated?
A = P × (1 + r/n)^(n×t)
Where:
ATotal amount after interestPPrincipal (initial investment)rAnnual interest rate / 100nCompounding frequency per year (1=annual, 12=monthly, 365=daily)tTime period in yearsCompound interest is interest calculated on both the initial principal and the accumulated interest. More frequent compounding increases the effective annual rate (EAR). Daily compounding gives slightly more returns than monthly, which gives more than annual.
Worked Examples
1₹1L at 10% for 5 years (Monthly compounding)
P = ₹1,00,000, r = 10% = 0.10
n = 12 (monthly), t = 5 years
Result: A = ₹1,00,000 × (1+0.10/12)^(60) = ₹1,64,701 | CI = ₹64,701
