Estimate bond yield to maturity from annual coupon C, face value F, current price P and years to maturity n using YTM ≈ [C + (F−P)/n] / [(F+P)/2].
输入年利息 C、面值 F、价格 P 与剩余年限 n,求近似 YTM。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| YTM approx | YTM ≈ [C+(F-P)/n]/[(F+P)/2] | Standard fixed income approx |
| Exact YTM | Solve P = sum(CF/(1+y)^t) | Iterative solver |
| Caveat | Approx ignores coupon reinvestment | Approximation error |
