Bonds
Bond or mutual fund? Compare what you keep
Compare after-tax cash flows, costs and risks — not just the headline return.
The headline is only the starting point
In my LinkedIn post, I compared a bond with an equity mutual fund using the same starting amount and holding period. The useful part of that exercise was not finding one product that wins for everyone. It was seeing how much the answer depended on the assumptions.
An interest rate on a bond and an assumed return on an equity fund are different things. One describes a contractual payment subject to the issuer meeting its obligations. The other is a projection for a market-linked investment.
Write down the cash flows first
When does interest arrive? Will you spend it or reinvest it? When will you redeem fund units? What costs arise when you buy or sell? These details can change the amount left at the end.
For example, an investment paying interest regularly may suit a cash-flow need even when another option has a higher projected final value. If you plan to reinvest interest, the return you can earn on those later payments is another assumption, not a given.
Tax needs its own line in the calculation
Interest income and gains from fund units can have different tax treatment. The result can depend on the instrument, holding period, acquisition date, tax regime and the investor’s wider circumstances.
This is why I would not turn a simple comparison into a rule that everyone below or above a particular income should buy one product. Ask your tax adviser to check the rules that apply to your situation and the year in question.
Do not make unlike risks look identical
A spreadsheet can put two projected ending values next to each other. It cannot make the underlying risks the same. A corporate bond has issuer and liquidity risks; an equity fund can experience substantial market fluctuations. Both can lose money.
You also need to think about what happens before the end date. Would a delayed bond payment create a problem? Would a market fall force you to redeem fund units at a difficult time?
Ask two questions before choosing
When do I need this money, and what will I actually keep after tax and costs? Those questions are more useful than asking which product has the better advertised number.
The answer may involve more than one investment. A portfolio can give different portions of money different jobs rather than make a single product carry every goal.
