Rrsp Future Value
1. **Problem Statement:** Caleb contributes 2750 at the end of every 3 months (quarterly) for 5 years into an RRSP earning 2.50% interest compounded quarterly. We need to find:
a. The future value of the fund at the end of 5 years.
b. The amount of interest earned over the 5-year period.
2. **Formula Used:** The future value of an ordinary annuity compounded periodically is given by:
$$FV = P \times \frac{(1 + r)^n - 1}{r}$$
where:
- $P$ = payment amount per period
- $r$ = interest rate per period
- $n$ = total number of payments
3. **Given Data:**
- $P = 2750$
- Annual interest rate = 2.50% = 0.025
- Compounded quarterly, so quarterly interest rate $r = \frac{0.025}{4} = 0.00625$
- Number of years = 5
- Number of quarters $n = 5 \times 4 = 20$
4. **Calculate Future Value:**
$$FV = 2750 \times \frac{(1 + 0.00625)^{20} - 1}{0.00625}$$
Calculate $(1 + 0.00625)^{20}$:
$$1.00625^{20} \approx 1.131408$$
Then:
$$FV = 2750 \times \frac{1.131408 - 1}{0.00625} = 2750 \times \frac{0.131408}{0.00625}$$
$$= 2750 \times 21.02528 = 57819.52$$
5. **Calculate Interest Earned:**
Total amount contributed:
$$2750 \times 20 = 55000$$
Interest earned:
$$57819.52 - 55000 = 2819.52$$
**Final Answers:**
- a. Future value of the fund after 5 years is **57819.52**
- b. Interest earned over 5 years is **2819.52**
