Flat rate vs reducing balance loans in Kenya: which costs more?
A 14% flat-rate loan costs far more than a 14% reducing-balance loan. See the real difference on a KES 500,000 loan and how to compare any offer.
On a KES 500,000 loan at 14.3% over 36 months, the reducing-balance repayment is KES 17,162 a month, but the same rate charged "flat" costs KES 19,847. That's KES 96,677 more over the loan.
The difference, in shillings
| Loan | Term | Reducing balance / month | Flat rate / month | Extra cost of flat rate |
|---|---|---|---|---|
| KES 200,000 | 12 months | KES 17,986 | KES 19,050 | KES 12,772 |
| KES 500,000 | 36 months | KES 17,162 | KES 19,847 | KES 96,677 |
| KES 1,000,000 | 60 months | KES 23,424 | KES 28,583 | KES 309,556 |
Both at 14.3% a year, before fees.
Why flat rate costs more
With a reducing balance, you pay interest only on what you still owe. As you repay, the interest shrinks. With a flat rate, interest is charged on the full original amount for the whole term, even when you've repaid most of it. A flat rate of 14% works out to roughly 23 to 25% on a reducing-balance basis, depending on the term.
Don't forget fees
Processing fees, insurance and excise duty on fees raise the true cost. A 2.5% upfront fee on a three-year loan adds about a percentage point a year. The loan calculator works out the true APR including fees.
What's a normal rate in 2026?
The Central Bank Rate has been 8.75% since February 2026, and the average commercial bank lending rate was about 14.3% in July 2026. Rates vary a lot by bank and borrower. The Hustler Fund charges 8% a year on short-term personal loans. Digital lenders must be licensed by the CBK, so check the CBK list before borrowing.
Five questions to ask before you sign
- Is the rate flat or reducing balance?
- What are all the upfront fees, including insurance?
- Is the rate fixed or can it change?
- What's the penalty for paying early?
- What's the total amount I'll repay?
How to convert a flat rate quote
Ask the lender for the total amount you'll repay, then put the loan amount, term and monthly payment into the loan calculator. If a lender only gives a flat rate, a quick guide is to multiply it by about 1.7 to get the reducing-balance equivalent for a two-to-five-year loan.
Mobile and digital loans
Mobile loans are often priced per 30 days, which looks small but is large per year. A "7.5% for 30 days" loan works out to more than 90% a year before compounding. Use them for real emergencies only, and repay on time to avoid penalties and negative credit bureau listings.
How much can you comfortably borrow?
Lenders often cap repayments at about a third to a half of take-home pay. A safer target is to keep all loan repayments under about 30% of take-home, so you can still save. Check your numbers with the salary calculator first.
Frequently asked questions
What is the difference between flat rate and reducing balance?
Flat rate charges interest on the original loan for the whole term. Reducing balance charges interest only on what you still owe, so it costs less at the same quoted rate.
Which is better, flat rate or reducing balance?
Reducing balance is cheaper at the same quoted rate. A flat rate is roughly equivalent to a reducing-balance rate about 1.7 times higher.
What is the average loan interest rate in Kenya in 2026?
About 14.3% for commercial banks in July 2026, according to CBK data, with individual banks ranging widely.
