Final answer:
Michael can use compound interest to calculate the future value of his TFSA investment.
Step-by-step explanation:
Compound interest is a powerful tool for saving money in the long run. If Michael saves $6,500 in his Tax-Free Savings Account (TFSA) at age 25 and assumes a 7% annual rate of return, he can calculate the future value of his investment using the compound interest formula: Future Value = Principal x (1 + Annual Interest Rate)^Number of Years. After 40 years, his $6,500 investment would have multiplied to approximately $92,413.50. Keep in mind that this calculation assumes no additional deposits or withdrawals during the 40-year period.
