true yield
True yield is the real return an investment actually pays you after fees, taxes, reinvestment timing and inflation have taken their share.
In plain English
Somebody always tells you a fixed deposit is paying 18 percent, and you nod like that number is the whole story, until the bank deducts withholding tax, adds a small commission you did not notice, and inflation calmly eats the rest before the year is out.
That gap between the shiny number advertised and what actually lands in your pocket, in real terms, is what true yield tries to capture.
Say a Lagos investor puts money into a commercial paper advertised at 20 percent yield. Sounds sweet. But there is a 10 percent withholding tax on the interest, a small custodian fee, and the interest is paid once at maturity rather than compounding along the way. Once you work through all of that, the true yield might land closer to 16 or 17 percent, still decent, but not the number on the flyer.
For someone in London sending money home through a naira denominated investment product, true yield matters even more, because currency conversion charges and transfer fees nibble at returns on both ends, and the number the app shows you in big bold letters is rarely the number you actually keep.
This is why seasoned investors ask a different question before they commit money anywhere. Not 'what is the advertised rate' but 'after tax, after fees, after inflation, what am I really earning'. That second question is the one that protects your pocket.
A fixed income fund advertises a 19 percent annual yield. After a 10 percent tax on interest, a 0.5 percent management fee, and inflation running at about 15 percent for the year, the true yield an investor actually feels in purchasing power is closer to 3 to 4 percent, even though the marketing number never changes.
Questions people ask
Is true yield the same as annual percentage yield (APY)?
Not quite. APY usually accounts for compounding but often ignores tax and fees. True yield goes further and strips out every real cost, including inflation, to show what you actually gain in value.
Why do investment products rarely advertise true yield?
Because the advertised gross yield looks more attractive, and marketing teams know a bigger number sells faster than an honest one. It is not necessarily dishonest, but it is incomplete, so the responsibility falls on you to do the extra sum.
How can I calculate true yield myself?
Start with the advertised rate, subtract any tax on the return, subtract fees or charges, then subtract the inflation rate for that period. What remains is a rough estimate of your true yield, and even a rough estimate beats none.
