  • Sometimes, perpetual bonds are preferred instead of dividend stocks. However, the similarities between the two are extremely limited.

  • Dividend interests are not mandatory to be paid. That is in the case of dividend payments, there are subtle fluctuations while in the case of dividend bonds, the payment is fixed.

According to some economists, perpetual bonds are excellent for raising money. However, some say that there is no point in creating debt that has to be paid forever. It might affect the fiscal and economic policies of the entities.

Do the Issuers Pay Forever?

The answer to this question is both yes and no. In the cases of perpetual bonds, the issuers usually continue with coupon payments forever. And, the payments are usually regular too. However, in some cases, the issuers can call and redeem the bonds. The issuers of bonds still get benefits as the perpetuities do not have a fixed and permanent redemption date.

Calculation of the Yield

The current yield on perpetual bonds is equal to the total number of coupons received annually divided by the market value of the bond multiplied by 100.

For example, assume that one has invested in a perpetual bond with a par value of INR 1,000 by purchasing the bond at a discounted price of INR 950. He/she receives a total of INR 80 per year in coupon payments.

$$ Current\:Yield = \frac{80}{950}× 100 = 8.42 % $$

The current yield from the bond is 8.42 %.
