Key Formulas in Government Bond Calculation
1. Current Yield
Current Yield=Annual Coupon PaymentPurchase Price×100\text{Current Yield} = \frac{\text{Annual Coupon Payment}}{\text{Purchase Price}} \times 100Current Yield=Purchase PriceAnnual Coupon Payment×100
2. Yield to Maturity (Approximate)
YTM≈C+F−PnF+P2YTM \approx \frac{C + \frac{F – P}{n}}{\frac{F + P}{2}}YTM≈2F+PC+nF−P
Where:
- CCC = annual coupon payment
- FFF = face value
- PPP = purchase price
- nnn = years to maturity
3. Maturity Value
The principal amount repaid at maturity, usually the face value.
Example Calculation
Assume you buy a government bond with:
- Face value: $1,000
- Purchase price: $950
- Coupon rate: 5%
- Years to maturity: 10 years
Annual coupon payment = 5% of $1,000 = $50
Current yield: 50950×100=5.26%\frac{50}{950} \times 100 = 5.26\%95050×100=5.26%
Approximate YTM: 50+1,000−950101,000+9502=50+5975=5.64%\frac{50 + \frac{1,000 – 950}{10}}{\frac{1,000 + 950}{2}} = \frac{50 + 5}{975} = 5.64\%21,000+95050+101,000−950=97550+5=5.64%
You can expect an approximate yield to maturity of 5.64%.
