About the Bond Calculator
Bond pricing is the inverse of interest rates: when market yields rise, existing bond prices fall, and vice versa. A bond paying a fixed 5% coupon becomes less attractive when new bonds pay 6%, so its price drops until the effective yield matches the market. This calculator computes the exact price and shows the premium or discount from face value.
Yield to Maturity (YTM) is the total annualised return earned by holding a bond to maturity, accounting for the purchase price, coupon payments, and face value at redemption. A bond purchased at $920 with a $1,000 face value and 6% annual coupon maturing in 5 years has a YTM of approximately 8.1% — meaningfully higher than the stated coupon.
Duration measures a bond's sensitivity to interest rate changes. A duration of 7 years means the bond's price will fall approximately 7% for every 1% rise in rates. This is why long-duration bonds are riskier in rising-rate environments.
Credit quality (investment-grade vs. high-yield) determines the spread above the risk-free rate. Investment-grade bonds typically trade at 50–200 basis points above Treasuries; high-yield bonds may trade at 300–800 basis points above, reflecting compensation for default risk.
