Bot GPT 4-o mini To calculate the future value of an annuity (the monthly contributions made to the IRA), we can use the future value of an ordinary annuity formula:
\[ FV = P \times \left( \frac{(1 + r)^n - 1}{r} \right) \]
Where:
- \( FV \) = future value of the annuity
- \( P \) = payment amount per period
- \( r \) = interest rate per period
- \( n \) = total number of payments
Given:
- Monthly deposit (\( P \)) = $60
- Annual interest rate = 6%
- Monthly interest rate (\( r \)) = \(\frac{6%}{12} = 0.5% = 0.005\)
- Number of years until retirement = \( 65 - 24 = 41\) years
- Total number of payments (\( n \)) = \( 41 \times 12 = 492\) months
Plugging in the numbers:
\[ FV = 60 \times \left( \frac{(1 + 0.005)^{492} - 1}{0.005} \right) \]
Calculating \( (1 + 0.005)^{492} \):
\[ (1 + 0.005)^{492} \approx 8.1573 \]
Now substituting this value back into the formula:
\[ FV = 60 \times \left( \frac{8.1573 - 1}{0.005} \right) \]
\[ FV = 60 \times \left( \frac{7.1573}{0.005} \right) \]
\[ FV = 60 \times 1431.457 (approximately) \]
Finally, calculate:
\[ FV \approx 85887.42 \]
Rounding gives us around $85,887.42.
Final Values Summary
- With monthly deposits of $60 at an annual interest rate of 6% compounded monthly for 41 years, you will have approximately $85,887.42.
However, it appears that none of the given options match closely with our computation. Let's ensure we don’t make any mistakes in approximation and the calculation for the future value would be:
Refine and Validate Calculation
-
Starting Value for Calculating:
- Monthly Contributions: \( P = 60 \)
- Monthly Rate: \( r = 0.005 \)
- Total Months: \( n = 492 \)
-
Plug Values:
- \[ FV = 60 \times \left( \frac{(1.005)^{492} - 1}{0.005} \right) \]
- Calculate \( (1.005)^{492} \):
- \( (1.005)^{492} \) ≈ 8.158 (accurate calculation should affirm a more precise value close to this)
- Calculate the subtraction and division:
- \( FV = 60 \times \left( \frac {7.158}{0.005} \right) = 60 \times 1431.6 \approx 85896.38 \)
