Take a borrower earning KES 150,000 gross a month who already pays KES 10,000 a month on an existing loan, and wants a new loan at 16% a year over 60 months under a 40% debt-service ratio. Net pay after Kenyan deductions is about KES 105,130. Forty percent of that is KES 42,052, and once the existing KES 10,000 commitment is taken out, KES 32,052 a month is free to service a new loan.

How it is calculated
The calculator works out how large a new loan your income can support without breaching a debt-service ratio. It runs your gross through the Kenyan payslip to find net pay, applies the chosen ratio to net pay, and subtracts any existing monthly debt repayments to leave the room available for a new loan. That free amount is then converted into a principal by inverting the reducing-balance amortisation formula: the loan equals the payment times one minus (1 plus the monthly rate) raised to the negative number of months, divided by the monthly rate. The monthly rate is the annual rate divided by 12. If existing debt and the ratio leave no room, the tool reports that no new loan fits. Lenders in Kenya often use a one-third to 40% ratio and look at net pay, so this gives a realistic ceiling, though your actual approval also depends on credit history and the lender's own policy.
Frequently asked questions
How much can I borrow on my salary in Kenya?
Lenders cap your loan by a debt-service ratio, the share of income that can go to loan repayments. Many Kenyan banks and SACCOs work to roughly a third of net pay. This calculator takes your gross salary, deducts PAYE and statutory contributions to get net pay, subtracts any existing debt repayments, applies your chosen ratio, and converts the affordable monthly payment into a maximum loan at your rate and term.
Why do Kenyan lenders use net pay rather than gross pay for loan affordability?
Net pay reflects the money actually available to service a loan after mandatory statutory deductions have been taken. Using gross would overstate borrowing capacity because a portion of every shilling is already committed to PAYE, NSSF, SHIF and the Housing Levy before it reaches the borrower. By working from net take-home, the debt-service ratio gives a more realistic ceiling that the borrower can genuinely afford.
What debt-service ratio do Kenyan banks and SACCOs typically apply?
Most Kenyan banks and SACCOs work to a debt-service ratio of around one-third to 40% of net monthly income. SACCOs sometimes allow slightly higher ratios for members with long savings histories. The exact limit varies by lender and also depends on credit history, employment type, and the specific loan product, so this calculator uses a ratio you can adjust to match your lender's actual policy.
How does a longer loan term affect the maximum loan amount in Kenya?
A longer term reduces the monthly repayment on a given loan, which means your affordable monthly payment can service a larger principal. Extending a 36-month loan to 60 months at the same rate and same monthly payment roughly increases the maximum loan by about 30%, though the total interest paid also rises significantly. Use the term input to see how stretching the repayment period changes both the maximum loan and the total cost.
