fin.bond-yield-to-maturity-Newton Calculator
Calculates bond yield to maturity using Newton-Raphson iteration for precise convergence on non-standard bonds. YTM assumes all coupons are reinvested at the YTM rate — when reinvestment rates differ, the realised yield will diverge from the stated YTM.
Inputs
Price
Current trading price. For bonds, rises when interest rates fall and drops when rates rise.
Face
The nominal value printed on the bond — what the issuer repays at maturity. Bonds trade above (premium) or below (discount) face value depending on interest rates.
Coupon Rate Pct
Annual interest a bond pays on its face value. A 5% coupon on a $1,000 bond pays $50/year regardless of what the bond trades for in the market.
Years
Reference formula or conversion factor shown for context.
Payments Per Yr
Reference formula or conversion factor shown for context.
Results
yield to maturity YTM
The value at the specified point or condition.
current yield
Electric charge flow rate (A). Governs wire sizing — too much current causes dangerous heating. Fuses protect circuits from overcurrent.
price vs par
The computed or recommended price.
coupon rate vs YTM
The value at the specified point or condition.
Newton-Raphson iteration for YTM
The proportional relationship between two quantities.
