How to read your result.
For anyone weighing a money market fund or a Treasury bill for an emergency fund or short-term savings.
Balance after tax
What you could have at the end once 15% withholding tax is taken from the interest. The yield is illustrative, so change it to match what you are seeing this week.
Interest you keep
The interest after tax. Compare this figure, not the headline rate, when you look at different options.
T-bill: pay today, receive at maturity
With a Treasury bill you pay less than the face value now and receive the face value at the end. The difference, minus tax, is your return.

Questions people ask.
How is money market fund interest taxed in Kenya?
Interest earned in a money market fund is generally subject to 15% withholding tax, which the fund deducts before the interest reaches you. This calculator applies 15% by default.
How does a Treasury bill work?
You lend money to the government for 91, 182 or 364 days. You pay less than the face value today, and at maturity you receive the face value. The difference is your interest, and withholding tax is taken from it.
Which money market fund has the best rate?
Fnsoko does not recommend specific providers. Rates change every week, so look at the fund's fees, how fast you can withdraw, and whether it is licensed by the Capital Markets Authority, not just the headline yield.
Is the MMF yield fixed?
No. A money market fund's yield moves with interest rates in the economy. The number you see advertised today is a recent average, not a promise.
