Coupon Reinvestment Income Calculator
Future value of reinvested coupons and the share of total bond return that depends on the reinvestment rate.
Formula
On a 20-year 6% bond, interest-on-interest can be a third of total coupon wealth — which is why realized compound yield falls short of quoted YTM whenever reinvestment rates drop. Long, high-coupon bonds carry the most reinvestment risk.
