1. **State the problem:** Sam agrees to pay $5,000 per month for 5 years on a car loan at 6.3% annual interest compounded monthly. We need to find the present value (PV) of the car loan.
2. **Formula used:** The present value of an annuity formula is
$$PV = P \times \frac{1 - (1 + r)^{-n}}{r}$$
where:
- $P$ is the monthly payment,
- $r$ is the monthly interest rate (annual rate divided by 12),
- $n$ is the total number of payments (months).
3. **Calculate the values:**
- Monthly payment $P = 5000$
- Annual interest rate = 6.3%, so monthly interest rate $r = \frac{6.3}{100 \times 12} = 0.00525$
- Number of payments $n = 5 \times 12 = 60$
4. **Substitute into the formula:**
$$PV = 5000 \times \frac{1 - (1 + 0.00525)^{-60}}{0.00525}$$
5. **Calculate the power term:**
$$ (1 + 0.00525)^{-60} = (1.00525)^{-60} $$
6. **Evaluate:**
$$ (1.00525)^{60} \approx 1.372786 $$
So,
$$ (1.00525)^{-60} = \frac{1}{1.372786} \approx 0.7281 $$
7. **Calculate numerator:**
$$ 1 - 0.7281 = 0.2719 $$
8. **Calculate fraction:**
$$ \frac{0.2719}{0.00525} \approx 51.84 $$
9. **Calculate present value:**
$$ PV = 5000 \times 51.84 = 259,200 $$
10. **Final answer:**
The present value of the car loan is approximately **259,200**.
This means the loan amount Sam is effectively borrowing is about 259,200, which is the amount needed today to cover all future payments at the given interest rate.
