The most important difference between the face value of a bond and its price is that the face value is fixed, while the price varies due to outside influences. The amount set for face value remains the same until the bond reaches maturity.
If you buy a new bond directly from the issuer and plan to keep it to maturity, changing prices, market interest rates, and yields typically do not affect you, unless the bond is called. However, you can also buy bonds from other investors on the secondary market. Similar to stocks, bonds can be higher or lower than the face value of the security because of the current economic environment and the financial health of the issuer.
