How Bonds Work
Bonds are loans you give to governments or companies. They pay you interest (the coupon rate) regularly and return your principal at maturity. Bond price = present value of all future payments. When interest rates go up, bond prices go down (and vice versa)—that is interest rate risk.
Key terms: Yield to Maturity (YTM) = total return if held until maturity. Duration = how sensitive the bond is to rate changes (higher duration = more price volatility). Coupon rate = annual interest as % of face value. Credit risk = chance the issuer defaults.
Frequently Asked Questions
What affects bond prices?
Interest rates (biggest factor—when rates go up, bond prices go down), credit quality (higher risk = lower price), time to maturity, coupon rate, and overall market conditions.
How do I calculate bond yield?
Yield to maturity (YTM) uses a complex formula that factors in current price, face value, coupon rate, and time to maturity. The calculator above does it for you.
Current yield vs. yield to maturity?
Current yield = annual coupon ÷ current price. YTM includes all future cash flows plus the principal you get back at maturity. YTM is more comprehensive.
