Lump Sum Present Value
1. **State the problem:** We want to find the lump sum deposited today (present value) that is equivalent to receiving $20,000 at the end of each year for 6 years, with an interest rate of 3% compounded annually.
2. **Formula used:** The present value of an ordinary annuity is given by:
$$PV = P \times \frac{1 - (1 + r)^{-n}}{r}$$
where:
- $P$ is the payment per period ($20,000$),
- $r$ is the interest rate per period ($0.03$),
- $n$ is the number of periods ($6$).
3. **Explanation:** This formula calculates how much a series of future payments is worth in today's dollars, considering the interest rate.
4. **Calculate:**
$$PV = 20000 \times \frac{1 - (1 + 0.03)^{-6}}{0.03}$$
5. **Evaluate the power:**
$$ (1 + 0.03)^{-6} = 1.03^{-6} \approx 0.83748 $$
6. **Substitute back:**
$$PV = 20000 \times \frac{1 - 0.83748}{0.03} = 20000 \times \frac{0.16252}{0.03}$$
7. **Simplify:**
$$PV = 20000 \times 5.4173 = 108346$$
8. **Interpretation:** The lump sum deposited today should be approximately $108,346$ to yield the same total amount as the 6 annual payments of $20,000 at 3% interest.
**Final answer:**
$$\boxed{108346}$$
