Compound Interestని ఎలా లెక్కించాలి
Compound Interest అంటే ఏమిటి?
Compound interest calculates interest on both the initial principal and the previously accumulated interest. Unlike simple interest (which only grows on the principal), compound interest grows exponentially — your interest earns interest. Einstein reportedly called it "the eighth wonder of the world."
