Formula and method
This calculator uses the values you enter and applies the calculation immediately in your browser. The main output formulas are:
- Approximate YTM:
((annualCoupon + (faceValue-price)/years) / ((faceValue+price)/2)) * 100
Some formulas are undefined for certain input combinations, such as division by zero, equal x-values in a slope calculation, or logarithms of non-positive numbers. In those cases the live tool reports that the result is undefined instead of displaying Infinity or NaN.
Examples
- Example: with Annual coupon payment = 50, Face value = 1000, Current price = 950, Years to maturity = 10, this calculator returns Approximate YTM = 5.641 %.
