Money Market Fund Calculator (Kenya, 2026)
By Nash Thuo · Updated June 2026
Money sitting idle loses value to inflation every month. A money market fund pays around 9% a year and you can still reach your cash within days. Use this calculator to see what consistent saving could become.
See your money grow
See how your money grows in a Kenyan money market fund. Add a starting amount and a monthly top-up, and watch compounding do the work.

Estimates assume monthly compounding and that you keep topping up every month. Real MMF yields move with interest rates, and interest is subject to 15% withholding tax (deducted at source). Use the tax toggle above to see the after-tax figure. This is an estimate, not a guarantee.
The power of compounding
Compounding means you earn returns on your returns. The interest your money makes this month starts earning its own interest next month. The two things that matter most are how much you add every month and how long you stay invested — far more than chasing the highest rate.
Take the default example: KES 10,000 to start and KES 5,000 a month at 9% for 5 years grows to about KES 392,000. You will have put in KES 310,000 of your own money; the other ~KES 82,000 is interest. Stretch it to 10 years and the interest portion grows much faster than the amount you save, because compounding accelerates with time.
Why a money market fund, not a savings account
- Higher return: ~9% a year versus the 0–2% most bank savings accounts pay.
- Still liquid: withdraw within 2–3 days, unlike a fixed deposit that locks your money.
- Low minimum: start with KES 1,000 and add any amount, any time.
- Low risk: the fund holds short-term government and bank instruments, regulated by the CMA.

Frequently Asked Questions
How much can a money market fund make in Kenya?
It depends on how much you save and the rate. As an example, KES 10,000 to start plus KES 5,000 a month for 5 years at 9% grows to about KES 392,000 — of which roughly KES 82,000 is interest you did not work for.
What is the current money market fund rate in Kenya?
Top Kenyan money market funds pay roughly 9% a year (gross) in 2026, though rates move with Central Bank policy and Treasury bill yields. This calculator lets you set your own rate.
Is money market fund interest taxed in Kenya?
Yes. MMF interest is subject to 15% withholding tax, deducted at source by the fund before it reaches you. Tick the tax box in the calculator to see your after-tax return.
How much do I need to start a money market fund?
Most Kenyan money market funds let you start with as little as KES 1,000, and you can top up any amount, any time.
Can I lose money in a money market fund?
Money market funds are low-risk and invest in short-term government and bank instruments, but they are not guaranteed and returns are not fixed. They are far safer than shares, and far more productive than cash sitting idle.
How fast can I withdraw from a money market fund?
Typically within 2 to 3 working days, straight to your bank or M-PESA — one of the reasons MMFs suit an emergency fund.
