Final answer:
To reach your retirement goal of $2.5 million in 45 years, you will need to earn a certain rate of return on your account. By using the formula for compound interest, you can calculate the rate of return needed based on the given information.
Step-by-step explanation:
To calculate the rate of return you need to earn on your account to reach your goal, you can use the formula for compound interest:
Final Amount = Principal imes (1 + Rate)^n
Let's break down the information given:
- Principal (P) = $20,000
- Annual Contribution (C) = $25,000
- Time Period (n) = 45 years
- Final Amount (A) = $2,500,000
Using the formula, we want to solve for the Rate (r):
$2,500,000 = ($20,000 + $25,000) imes (1 + r)^{45}
By rearranging the equation and solving for r, we can determine the rate of return needed to reach your goal.
