Calculator guide
Understanding Bond Coupon Reinvestment Calculator
Coupon reinvestment separates cash received from the additional value earned by putting each coupon back to work before maturity.
Calculation method
How the calculation works
Compound each periodic coupon at an entered reinvestment rate through maturity and separate coupon cash, reinvestment gain, and face value. Divide annual coupon by payment frequency, calculate remaining payments, apply an ordinary-annuity future value, and add face value at maturity.

Test more than one future rate
The eventual coupon value depends on rates not known today.
Worked situations
Practical examples
- A zero reinvestment rate leaves reinvested coupon value equal to coupon cash.
- Higher reinvestment rates raise maturity wealth.
- Face value is returned separately, absent default.
Better inputs
Useful tips
- Use date-specific modeling for precise results.
- Review call risk.
- Do not assume the bond's yield equals the reinvestment rate.
Before relying on the result
Limitations and common mistakes
- Equal periods and end-of-period coupons are assumed.
- Exact settlement, accrued interest, taxes, calls, defaults, and changing rates are excluded.
- Face value return is not guaranteed by this model.
