Final answer:
The fee lenders charge borrowers for the use of money and the return on investment is known as interest. Stocks have higher historical returns than bonds or savings accounts. Simple interest can be calculated using the formula involving principal, rate, and time.
Step-by-step explanation:
The fee charged by a lender to a borrower for the use of borrowed money, as well as the return on an investment, is known as interest. When money is deposited in a savings account at a bank, the depositor earns interest, which is a percentage of the deposit. This is the same principle when it comes to borrowing money for purchasing items like cars or computers, where the borrower must pay interest on the funds that are loaned.
Historical returns show that, on average, stocks have a higher return over time when compared to bonds and savings accounts. This is because stocks, which represent ownership in a company, can grow in value as the company grows and can also provide dividends to the shareholders. While higher risk can sometimes lead to higher rewards, it doesn't necessarily guarantee low returns; however, it does increase the potential for loss.
To calculate simple interest: use the formula Interest = Principal × Rate × Time. For a $5,000 loan at a 6% interest rate over three years, the total amount of interest would be $900 (5,000 × 0.06 × 3). Similarly, if $500 in simple interest was earned on a $10,000 loan over five years, the interest rate charged would have been 1% (500 / (10,000 × 5)).
