A reducing balance loan calculator helps you estimate your monthly loan repayments in Kenya by applying interest only to the remaining loan balance. As the principal reduces each month, the interest charged also decreases—making it more affordable long-term.

JazaLoan is a free, mobile-friendly financial tool designed to help Kenyans — including employees, self-employed individuals, and SMEs — make informed loan and salary-related decisions. We offer calculators for loan repayment, PAYE, NHIF, and NSSF with downloadable PDF breakdowns.
We support a wide range of loans including reducing balance, flat rate, SACCO loans, HELB, mobile loans (like M-Shwari or Fuliza), and SME financing. Our main goal is to help you understand and compare loans before making a financial decision.
A reducing balance loan charges interest on the remaining loan balance each month, meaning your interest reduces over time. A flat rate loan charges interest on the original loan amount for the entire period. Reducing balance is more cost-effective over time, and JazaLoan clearly explains both with full breakdowns.
PAYE is calculated based on income tax bands provided by KRA, along with deductions like housing levy, personal relief, and more. JazaLoan stays updated with the latest Finance Act changes to calculate your tax correctly.
As of 2025, NHIF contributions are calculated as a percentage of gross salary. JazaLoan reflects this updated formula, including minimum thresholds and employer contributions, based on the latest NHIF guidelines.
