**Summary**

The chapter titled “Why Save?” explains the concept of saving and its importance in managing money for the future. It begins by introducing the idea of disposable income, which is the money left after paying taxes. People can either spend or save this income. Saving means setting aside a part of the income to use in the future, helping people afford things they desire, like vacations or large purchases.

The chapter explains that saving early allows the money to grow, as saved money earns interest. Interest is the extra money that banks or companies give for keeping the money with them. There are two main types of interest: simple interest and compound interest.

Simple interest is calculated only on the initial amount saved, known as the principal. The formula for simple interest is straightforward, involving the principal amount, the rate of interest, and the time period for which the money is saved. For example, if ₹100 is saved at a 10% interest rate for one year, the interest earned will be ₹10.

Compound interest, on the other hand, is more powerful because it is calculated not only on the principal amount but also on the interest that has already been earned. This means that each year, interest is calculated on a growing amount. For example, if ₹100 is saved at a 10% interest rate, in the second year, interest is calculated on ₹110, not just ₹100. This process of earning interest on interest helps savings grow much faster over time.

The chapter concludes by stressing that saving is essential for financial growth. Starting early and understanding the difference between simple and compound interest can make a big difference in achieving financial goals.
