To calculate the Yield to Maturity (YTM) for a bond, we can use the following formula:
The YTM can be approximated by solving the following equation, which sets the present value of future cash flows equal to the price of the bond (M):
\[
M = \sum_{t=1}^{N} \frac{C}{(1 + YTM/2)^{t}} + \frac{F}{(1 + YTM/2)^{N}}
\]
Where:
- \(M\) is the market price of the bond (which is $100 in your case).
- \(C\) is the coupon payment, which can be calculated as \(C = \text{Face Value} \times \text{Coupon Rate} / 2\). Assuming the face value (F) is $100 (standard assumption unless specified otherwise), for a 5% coupon rate, the coupon payment is:
\[
C = 100 \times 0.05 / 2 = 2.5 \quad \text{(since it is semi-annual)}
\]
- \(N\) is the total number of periods (for 5 semesters, since each semester is 6 months, N = 5).
- \(F\) is the face value of the bond, which is typically $100.
Given \(M = 100\), \(C = 2.5\), and \(N = 5\), we can calculate YTM numerically since it generally does not have an analytical solution.
The equation becomes:
\[
100 = \sum_{t=1}^{5} \frac{2.5}{(1 + YTM/2)^{t}} + \frac{100}{(1 + YTM/2)^{5}}
\]
This equation is typically solved using numerical methods or financial calculators.
### Steps to Calculate YTM
1. **Initial Guess**: Start with an initial guess for YTM. A reasonable starting point might be the coupon rate (5%).
2. **Iterative Method**: Adjust the YTM based on whether the calculated bond price is above or below the market price. Repeat until you converge to a solution.
### Example Calculation
Let's try with a few possible rates.
1. **YTM = 5% (0.05)**:
\[
100 \approx \frac{2.5}{(1 + 0.025)^{1}} + \frac{2.5}{(1 + 0.025)^{2}} + \frac{2.5}{(1 + 0.025)^{3}} + \frac{2.5}{(1 + 0.025)^{4}} + \frac{2.5}{(1 + 0.025)^{5}} + \frac{100}{(1 + 0.025)^{5}}
\]
Calculate the right side: \\
The calculations show if 5% will give you $100 or less.
Continuing the calculations may require a calculator or iterative process until convergence is achieved.
For practical calculation, a financial calculator or computational software is better to find numerical roots.
### Conclusion
To find YTM accurately, perform the calculation iteratively until \(100 = \text{calculated present value}.\)
Using a trial-and-error method or a financial calculator will give you a close approximation of the YTM. For quick approximation, you might find it to be slightly less than the coupon rate due to the bond trading at par.
If you need a specific numerical solution, I suggest inputting the values into a financial calculator or software that can compute YTM accurately.
