Fixed Income Fund Returns in Kenya: Normalised Yield Table with As-At Dates
Comparing fixed income fund returns in Kenya should be straightforward: put each fund's yield into a table and find the highest.
In practice, it is more complicated.
Fund managers can report daily yields, effective annual yields, average returns or historical performance. Some figures are net of management fees but gross of withholding tax, while other comparison tables show returns after estimated tax.
The date matters too. A 14% yield reported in May should not automatically be compared with a 14% yield reported in August as though both describe today's market.
That is why a normalised yield table with clear as-at dates is useful.
Quick Answer: What Is a Normalised Yield?
Normalising means putting fund returns onto a reasonably consistent basis before comparing them.
For example, if Fund A reports an effective annual yield and Fund B reports an annualised average return, the labels should remain visible rather than pretending the figures are identical.
You should also record the date attached to every return.
The goal isn't to make different funds artificially identical. It is to make their differences transparent.
Imagine This
Suppose you see:
Fund A: 14.25%
Fund B: 14.18%
Fund A appears to be ahead.
But Fund A's figure may be a July net return after estimated withholding tax, while Fund B's figure may be an effective annual yield net of fees but before withholding tax.
Those numbers cannot fairly be ranked without understanding their basis.
This is one reason investors searching for the best fixed income funds in Kenya should never rely on percentages alone.
Normalised Fixed Income Yield Table
A useful market snapshot comes from July 2026 reporting compiled by Vasili Africa. The comparison applies the same methodology across the funds and reports both average and net returns.
| Fixed Income Fund | Annualised Return | Net Return | As-At Date |
|---|---|---|---|
| Mayfair Fixed Income Fund | 16.77% | 14.25% | 31 Jul 2026 |
| Nabo Africa Fixed Income Fund | 13.45% | 11.43% | 31 Jul 2026 |
| Zimele Fixed Income Fund | 11.66% | 9.91% | 31 Jul 2026 |
| NCBA Fixed Income Fund | 10.95% | 9.31% | 31 Jul 2026 |
| Kuza Fixed Income Fund (KES) | 10.94% | 9.30% | 31 Jul 2026 |
| Madison Fixed Income Fund | 10.34% | 8.79% | 31 Jul 2026 |
The category averaged approximately 11.02% before tax and 9.37% net during July.
This makes the table much more useful than combining figures collected randomly from different months.
Why Are As-At Dates So Important?
Fixed income funds do not maintain one permanent yield.
Their portfolios change, securities mature and interest rates move.
Mayfair illustrates this clearly. A May 2026 comparison reported its net return at approximately 14.14%, while the July comparison placed it at approximately 14.25%.
Neither figure is necessarily wrong.
They describe the fund at different times.
When building a fixed income fund returns Kenya calculator or comparison table, always attach a date to the input.
Without an as-at date, a yield quickly loses context.
What Does "Net" Actually Mean?

This requires particular care.
"Net" does not always mean the same thing across every website or factsheet.
For example, Etica states that the yield on its KES Fixed Income Fund is net of all fees but gross of withholding tax. Its management fee is 2% per year.
NCBA similarly states that its Fixed Income Fund rates are quoted gross of withholding tax and net of expenses, with a 2% annual management fee.
A third-party table may instead calculate a "net return" after applying withholding tax.
That means two percentages both labelled "net" could still represent different things.
Always read the methodology.

A Practical Etica Example
Etica's May 2026 factsheet reported an effective annual yield of 13.17% for its KES Fixed Income Fund. The figure was net of fees but gross of withholding tax. The fund had a KSh100 minimum investment and 2% annual management fee.
An Etica Fixed Income Fund calculator using that figure would therefore need to make clear whether tax is being deducted separately.
For example, applying 13.17% directly to KSh100,000 gives an illustrative annual amount of:
KSh100,000 × 13.17% = KSh13,170
But that should not automatically be described as the investor's final take-home income because the quoted yield was gross of withholding tax.
Gross, Net and Effective Annual Yield
These terms are worth separating.
Gross yield generally describes performance before specified deductions.
Net yield describes performance after specified costs—but you must check which costs.
Effective annual yield expresses the annual return while accounting for the applicable compounding methodology.
A high-quality comparison should therefore show both the percentage and its definition.
Without that information, ranking the best fixed income funds to invest in can create false precision.
Does the Highest Yield Mean the Best Fund?
No.
Mayfair's strong July figure put it well above the category average, but higher return should encourage further investigation rather than automatic selection.
A fixed income portfolio can increase potential returns by taking different levels of duration, credit or liquidity risk.
Longer-duration bonds, for example, can rise strongly when interest rates fall but can also experience greater price declines when rates rise.
This matters particularly when researching best 30 yr fixed income funds or other long-duration strategies.
Are Fixed Income Funds More Safe to Invest In?
The question "are fixed income funds more safe to invest in?" cannot be answered from a yield table.
Fixed income funds may generally experience less volatility than equity funds, depending on their portfolios, but they still carry investment risk.
Duration risk affects bond prices when interest rates move. Credit risk concerns whether borrowers can repay. Liquidity risk affects how easily investments can be sold.
The highest yield therefore isn't automatically the safest yield.
How Should You Compare Funds?
If you're researching fixed income mutual funds how to invest, use returns as one part of the decision.
Compare yields from the same period wherever possible. Check whether they are annualised, whether fees have already been deducted and whether withholding tax is included.
Then examine minimum investment, withdrawal time, portfolio composition and risk.
That gives you a much fairer comparison.
Frequently Asked Questions
Why do fixed income fund yields change?
Interest rates, bond prices, portfolio holdings and market conditions change over time, causing fund yields and performance to move.
Can I compare yields from different months?
You can use them for historical context, but they should not be treated as a like-for-like current ranking.
Are published net returns always after tax?
No. Some providers describe yields as net of fees but gross of withholding tax. Always check the methodology.
Final Thoughts
A normalised fixed income fund return table is valuable only when investors understand what the numbers mean.
The percentage, reporting basis and as-at date belong together.
Removing any one of them can turn a useful comparison into a misleading ranking.
Quick Tip
Never record a fund yield without recording its date and basis.
"14%" tells you very little.
"14% effective annual yield, net of fees, gross of tax, as at 31 July 2026" tells you considerably more.
