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

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
