If an investor purchases the bond at face value ($500) and the bond has a yield of 2% with a maturity of 1 year, the interest payment can be calculated as follows:
Interest payment = Face value × Yield = $500 × 2% = $500 × 0.02 = $10.
At maturity, the bondholder will receive the face value of the bond plus the interest payment. Therefore:
Total payment at maturity = Face value + Interest payment = $500 + $10 = $510.
So, the bondholder should expect to receive $510 at maturity.
