What could be the possible advantages and disadvantages of compound interest for savers and borrowers?
For savers, compound interest offers significant advantages. Money grows exponentially over time as interest is earned not just on the original amount but also on previously earned interest. Small regular savings can accumulate into substantial sums over long periods, and the longer the saving period, the greater the growth.
The chapter demonstrates this with an example where ₹1000 grows to ₹2012.20 in 12 years at 6% interest.
For borrowers, compound interest can be a disadvantage. Loans become more expensive over time as interest compounds, and borrowers may end up paying much more than the original loan amount. Debt can grow rapidly if not repaid promptly.
However, compound interest also incentivizes timely repayment and encourages financial discipline among borrowers.
Explanation
The chapter explains compounding through a detailed example showing how ₹1000 at 6% interest grows to ₹1060 after one year, then to ₹1123.60 after two years, as interest is earned on the accumulated amount including previous interest. The story of the King and Sage from Kerala illustrates how exponential growth through compounding can transform small amounts into enormous sums. The chapter states that compounding is a powerful financial concept that helps money grow exponentially over time.
