Final answer:
By investing $100,000 at an 8% annual interest rate, compounded annually, for 5 years, you will have $146,933 at the time of retirement.
Step-by-step explanation:
If you invest $100,000 at an 8% annual interest rate today, the amount you will have when you retire in 5 years can be calculated using the formula for compound interest. The formula for compound interest is A = P(1 + r/n)nt, where:
- P is the principal amount (the initial amount of money)
- r is the annual interest rate (decimal)
- n is the number of times the interest is compounded per year
- t is the number of years the money is invested for
- A is the amount of money accumulated after n years, including interest.
Assuming that the interest is compounded annually (n=1), the formula simplifies to A = P(1 + r)t. Plugging in your values: A = $100,000(1 + 0.08)5 = $100,000(1.08)5Calculating this out, A = $100,000 * 1.46933 = $146,933 (rounded to the nearest dollar). Therefore, you will have $146,933 when you retire in 5 years.
