How the calculator works
- Money market funds work out interest every day on your balance and credit it to your account at the end of each month.
- Funds advertise an effective annual yield. We convert it to a daily rate so that a full year earns exactly the advertised yield before tax.
- 15% withholding tax is deducted from each month's interest before it is credited.
- Top-ups land on the same date each month as your first deposit and start earning from that day. Funds may take a day or two to process a deposit, so real figures can be slightly lower.
- Yields change every day. A fund's yield today is not a promise of what it will pay next month.
Common questions
How much does KES 100,000 earn per day in a money market fund?
At an 11% effective annual yield, KES 100,000 earns about KES 28.70 a day before tax, or about KES 24.40 after 15% withholding tax. The calculator shows the exact daily figure for any amount and yield.
How is money market fund interest calculated in Kenya?
Interest is calculated daily on your balance and credited monthly, after 15% withholding tax. Because credited interest earns interest the next month, your money compounds monthly.
Which money market fund pays the highest interest?
Yields change daily. The comparison table below ranks the funds by their latest published yield, and our money market fund rates page shows the full list with minimum investments.
Is the advertised yield before or after tax?
Before tax. Kenyan funds quote effective annual yields before the 15% withholding tax, and after their management fee. The calculator deducts the tax for you.
How long does it take to withdraw from a money market fund?
Most Kenyan money market funds pay withdrawals within two to three working days.
