How It Works
The calculator uses the standard mortgage payment formula:
M = P × [r(1 + r)^n] ÷ [(1 + r)^n – 1]
Where:
- M is your monthly payment
- P is the loan amount (principal)
- r is the monthly interest rate (annual rate ÷ 12)
- n is the total number of payments (loan term in years × 12)
This formula calculates fixed monthly payments that include both interest and part of your loan principal.

Example
If you borrow KES 3,000,000 at an annual interest rate of 10% for 15 years:
- Monthly interest rate = 10 ÷ 12 = 0.833%
- Number of payments = 15 × 12 = 180
Your monthly payment will be about KES 32,237, and the total payment over 15 years will be around KES 5,802,660.
This means you’ll pay KES 2,802,660 in total interest.
