MMF Calculator Kenya — Estimate Your Daily & Monthly Returns
Introduction
Thinking about investing in a Money Market Fund (MMF) in Kenya?
One of the first questions most people ask is:
“How much money will I actually earn?”
The good news is:
MMFs make it fairly easy to estimate your potential returns.
In this guide, we’ll show you:
- How MMF returns are calculated
- Daily and monthly earnings examples
- Simple formulas you can use
- What affects your actual returns
Let’s break it down.
First, What Is an MMF?
A Money Market Fund is a low-risk investment fund that invests in:
- Treasury Bills
- Bank deposits
- Government securities
- Short-term debt instruments
In Kenya, MMFs are regulated by the Capital Markets Authority.
Most MMFs:
✅ Earn interest daily
✅ Credit returns monthly
✅ Allow flexible withdrawals
✅ Offer higher returns than normal savings accounts
How MMF Returns Are Calculated

MMFs usually advertise an annual interest rate, also called:
- Annual Yield
- Net Return
- Effective Annual Rate
To estimate your earnings:
Daily Return Formula
Daily Return = (Investment Amount × Annual Rate) ÷ 365
Monthly Return Formula
Monthly Return = (Investment Amount × Annual Rate) ÷ 12
Example 1: KSh 50,000 Investment
Let’s assume:
- Investment Amount = KSh 50,000
- Annual MMF Rate = 12%
Estimated Daily Earnings
= (50,000 × 0.12) ÷ 365
Approximate result: KSh 16.44 per day
Estimated Monthly Earnings
= (50,000 × 0.12) ÷ 12
Approximate result: KSh 500 per month

Example 2: KSh 200,000 Investment
Assuming the same 12% annual return:
Estimated Daily Earnings
= (200,000 × 0.12) ÷ 365
Approximate result: KSh 65.75 per day
Estimated Monthly Earnings
= (200,000 × 0.12) ÷ 12
Approximate result: KSh 2,000 per month
Quick MMF Earnings Table
| Investment | 10% Annual Return | 12% Annual Return | 15% Annual Return |
|---|---|---|---|
| KSh 10,000 | ~KSh 83/month | ~KSh 100/month | ~KSh 125/month |
| KSh 50,000 | ~KSh 417/month | ~KSh 500/month | ~KSh 625/month |
| KSh 100,000 | ~KSh 833/month | ~KSh 1,000/month | ~KSh 1,250/month |
| KSh 500,000 | ~KSh 4,167/month | ~KSh 5,000/month | ~KSh 6,250/month |
These are estimates before taxes and fees.
What Affects Your Actual Returns?

Your actual MMF earnings can change depending on:
1. Interest Rate Changes
MMF rates fluctuate based on market conditions and Treasury Bill rates.
2. Management Fees
Some funds deduct annual management fees.
3. Withholding Tax
Interest income in Kenya may attract withholding tax.
4. Compounding
Some MMFs reinvest earnings automatically, helping your money grow faster over
time.
Why MMF Returns Change Often
Unlike Fixed Deposits, MMF returns are:
Not fixed or guaranteed.
Returns move depending on:
- Central Bank rates
- Treasury Bill performance
- Market liquidity
- Economic conditions
That’s why one MMF may earn:
- 10% this month
- 12% another month
Simple Rule Most Investors Use
Here’s a quick shortcut many investors use:
At 12% annual return:
- Every KSh 100,000 earns roughly:
KSh 1,000 per month before tax
This is only an estimate, but it helps you plan quickly.
Is an MMF Worth It?
For many Kenyan savers, MMFs are attractive because they offer:
- Better returns than ordinary savings accounts
- Flexible access to funds
- Low starting amounts
- Daily interest accumulation
They are commonly used for:
- Emergency funds
- Savings goals
- Business reserves
- Short-term investing
