When taking a loan in Kenya—whether from a bank, Sacco, or a mobile lender—you will often hear the terms reducing balance and flat rate. These two interest calculation methods determine how much you end up repaying in total, and the difference can be huge.
At JazaLoan Calculator, our goal is to break down complex financial concepts into clear, practical knowledge so that Kenyans can make smarter borrowing decisions. Let’s explore how these loan types work, their advantages, disadvantages, and when to choose each one.
A reducing balance loan is calculated based on the remaining principal of your loan. With every repayment you make, your outstanding principal goes down, and so does the interest charged in the next cycle. This creates a repayment schedule where interest gradually decreases, while the portion of principal repayment increases over time.
For example, banks like KCB, Equity Bank, and Standard Chartered use this method for products such as mortgages, asset financing, and long-term personal loans.

A flat rate loan charges interest on the original principal throughout the loan’s entire term. This means the total interest is calculated upfront, added to the loan, and divided evenly across the repayment period. Each installment remains fixed—making it predictable, but often more expensive.
This method is common among mobile loan apps (M-Pesa, Tala, Branch), microfinance institutions, and hire purchase agreements. It’s attractive for short-term borrowing but comes with hidden costs.

There’s no one-size-fits-all answer. Your choice depends on your financial goals and the size of the loan:
Always request a repayment schedule from your lender before signing. Better yet, run the numbers yourself with a trusted loan repayment calculator.

This means as you repay, your interest amount reduces, making it more affordable in the long run. Common examples include mortgages, car loans, and business loans from Kenyan banks like KCB, Equity, and Co-op Bank.
A flat rate loan charges interest on the original loan amount for the entire period, regardless of repayments made. This type is mostly used by mobile lenders (M-Pesa, Tala, Branch), hire purchase dealers, and microfinance institutions due to its simplicity.
A reducing balance loan is almost always cheaper because your interest reduces as you repay. Flat rate loans may look affordable at first but end up costing much more in the long run. For large loans, reducing balance is the smarter choice.
Yes! Early repayment reduces your outstanding principal, which lowers future interest. This can save you a significant amount of money — especially with mortgages and long-term bank loans.
Mobile loan apps prefer flat rate because it’s simple and predictable. Every borrower knows exactly what they’ll pay. However, the downside is much higher effective interest costs, so always calculate the true cost before borrowing.
