Borrowing wisely: how much loan can you really afford?
Qualifying for a loan and affording it are not the same thing. Use these simple checks before you borrow.

Your deposits may qualify you for a large loan, but the more useful question is: what can you comfortably repay every month, even when life gets expensive?
1. Start with the one-third rule
For salaried members, Kenya’s Employment Act limits total deductions from wages so that you keep at least one-third of your pay. Treat that as the absolute floor, not a target. If a new instalment would push your take-home pay close to that line, the loan is too big.
2. Work out your real monthly budget
List what you actually spend in a typical month:
- Rent or mortgage, food, transport and utilities
- School fees and other termly costs (divide them by the months they cover)
- Existing loan repayments, including mobile loans
- Support for family and regular contributions
- Your monthly SACCO savings — do not stop saving to repay a loan
What is left is the most you could put towards a new instalment. Aim to use no more than half of it, so you keep a buffer.
3. Check your debt-to-income ratio
Add up every monthly debt repayment and divide it by your gross monthly income. Many lenders become cautious above about 40%. Lower is safer.
4. Match the loan to its purpose
- Emergencies: borrow only what the emergency needs and repay quickly.
- School fees: choose a term that ends before the next term’s fees are due.
- Development or business: make sure the project’s benefit or income is realistic and arrives in time to support repayments.
5. Stress-test it
Ask yourself: if my income fell by a fifth for three months, could I still pay? If the answer is no, reduce the amount or lengthen the term — while remembering that a longer term means more interest overall.
A good loan improves your life after the last instalment. A bad loan only moves today’s problem into next year.
Before you apply
- Use the loan calculator to see instalments, interest and charges.
- Talk to your guarantors early and honestly about the amount and term.
- Keep saving every month — it protects your future borrowing power.
