Looking at two bonds from the same issuer. Same rating, similar yield, same tenure. One pays semi-annually and one pays monthly. The monthly payout one sounds more appealing because of more frequent income. But a friend told me the actual return ends up being the same. Is she right or is monthly genuinely better?
Your friend is broadly right on the underlying return if you are looking at it purely as a YTM comparison. A bond with an annual coupon of 9% pays the same total coupon whether it comes in two payments of 4.5% each or twelve payments of 0.75% each. The YTM calculation accounts for the timing and gives you a comparable annualised figure regardless of payout frequency. So on a pure return basis, if the YTM is the same, the actual return over the tenure is the same.
then why do some bonds advertise monthly payout as a feature. feels like marketing
It is partly marketing and partly genuinely useful depending on your situation. For someone who needs regular income, a retiree drawing down their portfolio for example, monthly payments smooth out cash flow. You receive money every month rather than waiting six months between payments. For someone reinvesting the coupons rather than spending them, monthly frequency theoretically allows more frequent reinvestment. But at realistic rates the compounding difference between monthly and semi-annual is very small.
is there a tax difference between monthly and semi-annual payout
No difference in tax rate. Both are taxable as income from other sources at your slab rate in the year received. The TDS threshold of Rs 5,000 per issuer per year applies the same way. The only practical tax timing difference is that with monthly payouts you receive taxable income spread across more dates in the year, which might affect advance tax calculations for large holdings. But the total annual tax liability is identical.
One thing worth checking when comparing monthly versus semi-annual bonds from the same issuer. Sometimes the monthly payout version carries a slightly lower YTM to compensate the issuer for the operational cost of twelve payments per year instead of two. If the monthly bond yields 8.85% and the semi-annual yields 9.00%, the semi-annual is actually better on a return basis even though the monthly feels more frequent. Always compare YTM figures, not coupon frequencies.
this is really helpful. so monthly payout is genuinely useful if I need regular income for expenses. for accumulation where I am reinvesting the coupons it does not matter much and I should compare on YTM. and I should check whether the monthly version has a lower YTM than the semi-annual from the same issuer before deciding.
That is exactly the right framework. If the YTMs are equal, choose based on your cash flow needs. If the YTMs differ, go with the higher YTM and adjust your cash management accordingly.
