How Much Does KSh 100,000 Earn in a 91-Day Treasury Bill in Kenya?
Updated June 2026 Guide Using Latest CBK Treasury Bill Auction Rates
🇰🇪 Treasury Bills Remain One of Kenya's Safest Investments
If you have KSh 100,000 and want a low-risk investment backed by the Government of Kenya, a 91-Day Treasury Bill (T-Bill) is one of the safest places to put your money.
Treasury Bills are short-term government securities issued by the Central Bank of Kenya (CBK). They allow investors to lend money to the government and earn a return over a fixed period.
Unlike shares whose prices fluctuate daily, Treasury Bills provide predictable returns and are considered among the lowest-risk investments available in Kenya.
Important Update:
The current minimum face value investment for Treasury Bills is KSh 50,000 for non-competitive bids and KSh 2,000,000 for competitive bids.
📘 What is a 91-Day Treasury Bill?
A 91-Day Treasury Bill is a short-term government security that matures after 91 days (approximately 3 months).
When you invest in a Treasury Bill, you do not receive monthly interest payments. Instead, Treasury Bills are sold at a discount and redeemed at their full face value upon maturity.
The difference between what you pay and what you receive at maturity becomes your profit.
Example:
You may pay approximately KSh 97,830 today and receive KSh 100,000 after 91 days.
Your profit is approximately KSh 2,170.

🧮 How Much Does KSh 100,000 Earn in a 91-Day Treasury Bill?
Using the latest available 91-Day Treasury Bill average rate of 8.7067% per annum, we can estimate the return an investor may earn over a 91-day investment period.
Because Treasury Bills are sold at a discount, investors pay less than the face value and receive the full face value when the bill matures.
Remember: The 8.7067% figure is an annualized rate. Investors earn only the portion corresponding to the 91-day investment period.
📐 Treasury Bill Calculation Formula
Treasury Bills use discount pricing rather than traditional interest payments.
Purchase Price = Face Value × [1 − (Rate × Days ÷ 365)]
Using:
- Face Value = KSh 100,000
- Rate = 8.7067%
- Days = 91
Estimated Purchase Price:
≈ KSh 97,830
At maturity, the investor receives:
KSh 100,000
Estimated Gross Profit:
KSh 2,170

💡 Understanding Treasury Bill Discount Pricing
One of the biggest misconceptions among investors is believing that Treasury Bills pay interest like a bank account.
They do not.
Instead, Treasury Bills are issued below their face value.
You buy cheaper today and receive the full amount at maturity.
For example:
- You invest in a Treasury Bill with a face value of KSh 100,000.
- You pay approximately KSh 97,830.
- After 91 days, CBK pays you KSh 100,000.
- Your gain is approximately KSh 2,170.
This discount system is what generates your return.
