What tool demonstrates the time value of money by considering principal, rate, and time?

• A. Budget planner
• B. Compound interest calculator
• C. Loan amortization schedule
• D. Credit score calculator

Answer: (B)

Time value of money is the idea that money you have now is worth more than the same amount in the future because it can earn interest. The tool that demonstrates this using principal, rate, and time is the compound interest calculator. By inputting the initial amount (principal), the interest rate (rate), and the number of years (time), it shows how the money grows due to interest that compounds over each period, highlighting how longer time horizons or higher rates lead to greater future value. This helps you see why investing sooner can yield more money later.

A budget planner focuses on tracking income and expenses rather than how money grows with interest. A loan amortization schedule breaks down payments over time to show how much goes to interest versus principal as a loan is repaid, which is about debt reduction rather than growth. A credit score calculator estimates creditworthiness, not the growth of money over time.
