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.

Yield has two sources Bond return and coupon reinvestment can differ.
Timing matters Earlier coupons compound longer.
Face value is principal Do not count it as coupon income.
Calls alter the path Cash flows may end early.

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.

Reinvestment risk

Test more than one future rate

The eventual coupon value depends on rates not known today.

Low Coupons earn less than expected.
Central Uses the entered assumption.
High Coupons compound faster.
Cash Unreinvested coupons earn no modeled gain.

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.
