Learn what an amortizable bond premium is and why investors and accountants spread a bond premium over the security's remaining life.
An amortizable bond premium is the amount paid above a bond’s face value that can be allocated over the bond’s remaining life rather than treated as one undivided amount forever.
The premium exists because the bond’s coupon is more attractive than current market yields. Amortization gradually reduces the carrying amount of the premium and helps align reported interest income or expense with the bond’s effective yield over time. The exact treatment depends on whether the focus is accounting, tax reporting, or issuer-side amortization.
If an investor pays $1,080 for a bond with a $1,000 face value, the $80 premium can be amortized over the remaining periods until maturity.
An investor says, “If I paid a premium, my coupon alone tells me my real return.” Is that correct?
Answer: No. The premium lowers the effective yield, which is why amortization matters.
