1. **State the problem:** You want to retire in 16 years with a future value equivalent to 15,000,000 in today's money, considering 3% inflation.
2. **Adjust the target amount for inflation:** The future value needed is calculated by adjusting for inflation using the formula:
$$FV = PV \times (1 + i)^n$$
where $PV=15,000,000$, $i=0.03$, and $n=16$.
Calculate:
$$FV = 15,000,000 \times (1.03)^{16}$$
3. **Calculate the future value:**
$$FV = 15,000,000 \times 1.604706 = 24,070,590$$
4. **Determine the annual contribution needed:** You will contribute every year for 16 years with an investment return rate of 5%. The future value of an ordinary annuity formula is:
$$FV = P \times \frac{(1 + r)^n - 1}{r}$$
where $P$ is the annual contribution, $r=0.05$, and $n=16$.
Rearranged to solve for $P$:
$$P = \frac{FV \times r}{(1 + r)^n - 1}$$
5. **Substitute values:**
$$P = \frac{24,070,590 \times 0.05}{(1.05)^{16} - 1}$$
Calculate denominator:
$$(1.05)^{16} = 2.182874$$
So:
$$P = \frac{24,070,590 \times 0.05}{2.182874 - 1} = \frac{1,203,529.5}{1.182874}$$
6. **Simplify the fraction:**
$$P = \frac{\cancel{1,203,529.5}}{\cancel{1.182874}} = 1,017,600$$
7. **Final answer:** You need to contribute approximately **1,017,600** every year for 16 years to reach your retirement goal adjusted for inflation.
