What Is Yield to Maturity?
Yield to Maturity (YTM) is essentially the total return an investor can expect to receive if they hold a bond until it reaches its maturity date. Think of it as the effective annualized rate of return for a bond. It takes into account not just the regular interest payments (called coupon payments) you get, but also any difference between the price you paid for the bond and its face value (known as par value) when it matures. For instance, if you buy a bond at a discount (below its par value), that discount contributes to your total return. Conversely, if you buy it at a premium (above its par value), that premium will reduce your overall return over time. YTM also assumes that all the interest payments you receive are reinvested at the same YTM rate throughout the bond's life. This makes it a comprehensive measure of a bond's attractiveness as an investment, especially for comparing different bonds with varying prices, coupon rates, and maturity dates. For tax purposes, the original issue discount (OID) on certain bonds, which contributes to YTM, must be reported annually, even if you don't receive it in cash. This is governed by principles outlined in the Internal Revenue Code, particularly related to accrual of OID under IRC §1272, and further guidance can be found in IRS Publication 550, Investment Income and Expenses.
