Tom wants to retire with $1,000,000 in 30 years. If his investments earn 6% annually, how much should he approximately invest each year to reach his goal?

To find out how much Tom should invest each year to reach his goal of $1,000,000 in 30 years with an annual interest rate of 6%, we can use the future value of an annuity formula:

\[
FV = P \times \frac{(1 + r)^n - 1}{r}
\]

Where:
- \(FV\) is the future value of the annuity (the amount he wants, $1,000,000),
- \(P\) is the annual payment (amount he needs to invest each year),
- \(r\) is the annual interest rate (6% or 0.06), and
- \(n\) is the number of years (30).

We need to rearrange this formula to solve for \(P\):

\[
P = \frac{FV \times r}{(1 + r)^n - 1}
\]

Substituting the values into the formula:

- \(FV = 1,000,000\)
- \(r = 0.06\)
- \(n = 30\)

Now we calculate:

\[
P = \frac{1,000,000 \times 0.06}{(1 + 0.06)^{30} - 1}
\]

Calculating \((1 + 0.06)^{30}\):

\[
(1.06)^{30} \approx 5.74349
\]

Now substituting that back into the equation:

\[
P = \frac{1,000,000 \times 0.06}{5.74349 - 1}
\]

Calculating the denominator:

\[
5.74349 - 1 \approx 4.74349
\]

Now substitute this value back into the equation for \(P\):

\[
P \approx \frac{60,000}{4.74349} \approx 12,629.70
\]

Thus, Tom should invest approximately **$12,630** each year. The closest answer from the options given is:

**B. $12,000** (as it's the closest approximation).
