How Much Loan Can You Afford?

Affordability is not the largest amount a lender is willing to approve. It is the payment you can continue making while meeting essential costs and absorbing normal setbacks. Start with reliable cash flow rather than a loan multiplier.

Build a realistic monthly picture

1. Use stable take-home income. Treat irregular income conservatively.
2. Add recurring income only when its pattern is defensible.
3. Subtract housing, food, transport, school, medical, utilities and other essential expenses.
4. Subtract every existing loan, hire-purchase and credit repayment.
5. Reserve money for savings, annual costs and emergencies.
6. Stress-test the remaining amount against a weak month or an interest-rate change.

Disposable income is not all repayable

If income less expenses and existing debt is KES 30,000, committing all KES 30,000 to a new loan leaves no margin for volatility or overlooked costs. A sustainable installment needs a buffer. The appropriate buffer depends on household responsibilities, income consistency and emergency savings; there is no single percentage suitable for everyone.

A worked monthly example

Assume the following self-reported figures:

KES 45,000 is the mathematical remainder, not an automatic loan installment. A proposed KES 300,000 amortised loan at 12% a year over 24 months would have an estimated monthly payment of about KES 14,122 before fees. Existing and proposed debt payments would then total about KES 24,122, or approximately 20.1% of the stated income.

The remaining cash flow after the proposed payment would be about KES 30,878 under the assumptions above. That buffer must still cover expenses omitted from the monthly estimate, price changes and emergencies.

Stress-test a weaker month

If the KES 120,000 income temporarily fell by 20% to KES 96,000 while the other amounts stayed unchanged, the cash remaining before the proposed loan would fall from KES 45,000 to KES 21,000. After the estimated KES 14,122 payment, only about KES 6,878 would remain.

This does not automatically make the loan unaffordable, but it exposes the dependency: the payment works comfortably in the normal month and becomes much tighter after an income shock. Someone with irregular income, dependants or little emergency savings may need a smaller installment or shorter list of non-essential commitments.

Convert an installment into a loan amount carefully

An affordable installment does not translate into one universal principal. The loan amount depends on the interest method, rate, payment frequency and term. A longer term may support a larger principal or lower payment but can increase the total interest paid and keep the household committed for longer.

Use the same affordable-payment ceiling to compare several terms, then reject a term that outlives the useful benefit of the borrowing. A short-lived expense financed over many years can leave repayments after the benefit is gone.

Costs the installment may not show

• Application, appraisal or legal charges.
• Credit-life or other insurance.
• Account, collection or payment-channel fees.
• A deduction from the approved amount before disbursement.
• Variable-rate changes permitted by the contract.
• Late charges and recovery expenses if repayment fails.

Ask for both the amount financed and the net cash you will receive. A loan can appear to fit monthly while delivering less usable money than expected.

Affordability and approval answer different questions

Your budget asks, “Can I keep paying without destabilising essential needs?” The lender's assessment asks whether the application meets its policy and evidence requirements. A lender may decline a loan that appears affordable because of eligibility, documentation, security or risk rules. It may also approve an amount larger than you personally consider comfortable.

The Sacco Societies Act requires evidence of ability to repay for an application covered by its lending provisions, while the applicable regulations require credit policies and lending disclosures. Neither replaces the borrower's own conservative budget.

Check the full term

• Will the income continue for the full loan duration?
• Are school fees, rent changes, insurance or taxes missing from the monthly estimate?
• Could a guarantor commitment turn into an obligation?
• Would the payment still work after a temporary income reduction?
• Does the loan finance something whose benefit lasts at least as long as the debt?

Add one final question: if the answer depends on overtime, a bonus or business sales that have not yet occurred, what happens when that income arrives late?
