Current Yield = (Annual Interest Payment / Purchase Price) × 100%. Yield to Maturity considers both interest payments and the difference between purchase price and face value at maturity.
- Current yield: $500 annual interest / $9,500 purchase price = 5.26%
- YTM adds capital gain/loss: ($500 + ($10,000 – $9,500)/10) / $9,500 = 5.79%
- Coupon rate is fixed at issuance; yield changes as market price fluctuates
- When bond prices drop 10%, yields rise proportionally – they move inversely
