User question:
user: I'm currently weighing up some investment options and would like to get an idea of their potential growth over time. Could you help me calculate the future value for a bond with an initial investment of $5000, an annual interest rate of 5%, and a term of 10 years; a mutual fund that starts with $2000, grows at an annual rate of 7%, and will be held for 15 years; and stocks starting at $1000, with an impressive annual growth rate of 10%, over a 20-year period? I need to understand the future values to make an informed decision.
