Does investor has options of Compound Frequency

In most real-world investments, no, investors usually do not choose the compounding frequency. The fund or investment product determines how earnings are calculated and credited.
The confusion often comes from financial calculators, which allow you to compare hypothetical scenarios.
What happens in a Money Market Fund?
For a Nigerian money market fund such as those managed by:
arm.com.ng
stanbicibtc.com
meristemng.com
you typically see an annualized yield (for example, 18% p.a.).
This does not mean interest is paid once per year.
Instead:
The fund earns income daily from treasury bills, deposits, commercial papers, etc.
The fund’s Net Asset Value (NAV) is updated regularly (usually daily).
Your returns are automatically retained in the fund unless you redeem.
Future returns are earned on both your principal and accumulated gains.
In effect, the compounding is happening automatically.
Why calculators ask for monthly, quarterly, or yearly compounding
The calculator is asking:
“If an investment earns 18% per year, how often are gains added back to the principal?”
For the same 18% nominal rate:
Annual compounding → slightly lower ending value
Quarterly compounding → slightly higher
Monthly compounding → higher still
Daily compounding → highest
But the differences are usually modest.
For Nigerian Money Market Funds
A practical way to think about them is:
Returns accrue daily.
The published yield is annualized.
Reinvestment is automatic while your money remains invested.
You generally cannot tell the fund manager, “Please compound quarterly instead of daily.”
The fund’s operating structure determines that.
Example
Suppose:
Initial investment = ₦1,000,000
Fund yield averages 18% per annum
You leave everything invested
Whether the fund compounds daily or monthly is determined by the fund’s accounting and NAV calculation methodology, not by your preference.
Your main decision is usually:
Option A: Leave earnings in the fund (compound growth).
Option B: Redeem part or all of the investment periodically (reducing compounding).
For your long-term wealth-building goal
The more important factor is usually whether you keep reinvesting and adding fresh contributions, not whether compounding is monthly versus daily.
For example:
₦15,000 monthly contribution for 20 years at 15–18% average returns
versus
₦15,000 monthly contribution for 20 years with a slightly different compounding convention
The monthly contributions have a much larger effect on the final portfolio value than the difference between monthly and daily compounding.
So when you see “18% annualized yield” on an ARM or other money market fund, assume the fund handles the compounding internally. Your job is mainly to decide:
How much to invest,
How often to add money, and
Whether to leave the gains invested.
