Prime Bank interest rates explained
Under CBK’s Risk-Based Credit Pricing Model, a variable-rate loan is priced as a reference rate (the Central Bank Rate, 8.75% as of October 2026, or KESONIA) plus a customer premium called “K”. Fees and charges come on top. CBK data shows Prime Bank Limited lent at an average of 13.96% in August 2026, 0.38 percentage points below the sector-wide 14.34%. That places it 12th of 36 lenders by cost.
Getting an accurate estimate
The rate box is editable, so the more exact your input, the better the result. Use the figure from your Prime Bank quotation if you have one, or keep the CBK average to get a rough idea. Compare a few terms, such as 12, 24 and 36 months, and watch how the monthly cost and the total interest move in opposite directions.
For example, KES 100,000 over 36 months at 13.96% on a reducing balance costs about KES 3,416 a month.
What you typically need
Expect to provide your national ID or passport, KRA PIN, payslips or six months of bank statements, and a clean credit bureau record. Secured facilities, such as car or property loans, need valuation and ownership documents too.
Reducing balance vs flat rate
The method matters as much as the headline rate. Take a 12-month loan at 14%: on a reducing balance, the interest shrinks every month as you pay down the principal. A flat rate charges 14% on the full original amount for the whole year, which makes the true cost much higher, close to double. Switch the method dropdown above to see the difference for your own Prime Bank loan.
Tips for a cheaper loan
- Pay down existing debts first to improve your credit score.
- Offer security if you can, because secured loans usually carry lower premiums.
- Ask whether you can make early repayments without a penalty.
- Read the key facts document Prime Bank gives you before you sign.
