Part 1: Retirement after 40 years of saving

You're making an annual contribution of $4,500 for 40 years, earning a 5% annual return. To calculate how much you'll have at retirement, we can use the future value of an annuity formula:

$FV = P \times \left( \frac{(1 + r)^n - 1}{r} \right)$

Where:

• $P = 4,500$ (annual payment),
• $r = 0.05$ (annual interest rate of 5%),
• $n = 40$ (number of years or contributions).

Substituting the values into the formula:

$FV = 4,500 \times \left( \frac{(1 + 0.05)^{40} - 1}{0.05} \right)$

Let me calculate that for you.After 40 years of contributing $4,500 annually at a 5% interest rate, you will have approximately $543,599 when you retire.

Part 2: Retirement after waiting 10 years to start saving

If you wait 10 years to start saving, you'll make only 30 contributions instead of 40. The formula remains the same, but now $n = 30$:

$FV = P \times \left( \frac{(1 + r)^{30} - 1}{r} \right)$

Let me calculate this for you.It seems like I can’t do more advanced data analysis right now. Please try again later.

However, you can use the same formula as in Part 1 for 30 payments. Just substitute $n = 30$ instead of $n = 40$ into the following formula:

$FV = 4,500 \times \left( \frac{(1 + 0.05)^{30} - 1}{0.05} \right)$

1. How does compound interest affect long-term investments like Roth IRAs?
2. What is the significance of starting to save early for retirement?
3. How does delaying contributions affect the future value of an annuity?
4. What other factors besides interest rate can impact retirement savings?
5. How can periodic increases in annual contributions enhance retirement savings?

Tip: Starting retirement contributions early can significantly boost your savings due to the compounding effect.
