An investment that pays you a set amount of money at regular intervals.

What is a fixed-income security?

A fixed-income security is a type of investment that pays you a set amount of money at regular intervals – kind of like earning interest on a savings account. The most common examples are bonds, where you lend money to a government or company in exchange for fixed interest payments (also called coupons) and your money back at the end of the term.

Fixed-income securities are generally seen as lower risk than stocks because they provide steady, predictable returns. However, they’re not completely risk-free – if the issuer struggles financially, they might not be able to pay you back.
