The yield to maturity of the bond is 10.5%.
To calculate the yield to maturity (YTM) of the bond:
1. Identify the variables:
Face Value (FV) = $1,000
Purchase Price (PV) = $875
Coupon Payment (PMT) = $80 (semi-annual)
Number of Years to Maturity (N) = 10 years
Number of Coupon Payments per Year (P/YR) = 2 (semi-annual)
2. Set up the formula:
The formula for YTM is:
YTM = PMT * [(1 - (1 + I/YR)^(-N * P/YR)) / (I/YR)] + (FV - PV) / (N * P/YR)
3. Substitute the values:
YTM = 80 * [(1 - (1 + I/YR)^(-10 * 2)) / (I/YR)] + (1000 - 875) / (10 * 2)
4. Solve for YTM using a financial calculator:
Set P/YR to 2 (semi-annual)
Set N to 20 (total number of coupon payments)
Set PV to -875 (negative because it represents an outflow)
Set PMT to 80
Set FV to 1000
Solve for I/YR (YTM)
5. Calculate the YTM:
Using a financial calculator, we get the YTM as:
YTM = 10.5%
Therefore, the yield to maturity of the bond is 10.5%.
