Learn what debt‑to‑income ratio is, why lenders use it, and how to lower your DTI to improve loan eligibility. Simple steps for Kenyan borrowers.
You apply for a loan.
Your income is good. Your credit record is clean.
But the lender still offers you less than you expected.
Why?
The answer may be your debt‑to‑income ratio (DTI) .
This number is one of the most important tools lenders use.
Yet most borrowers have never heard of it.
In this guide, you’ll learn:
What debt‑to‑income ratio is
How to calculate yours in minutes
What a good DTI looks like
How lenders use DTI to decide loan limits
Proven ways to lower your DTI fast
Let’s start with the definition.
Quick Answer- How do I calculate my debt‑to‑income ratio?
Divide your total monthly debt payments by your monthly gross income, then multiply by 100. For example, if you earn KES 60,000 and pay KES 24,000 in debts, your DTI is 40%.
Debt‑to‑income ratio is the percentage of your monthly gross income that goes toward paying debts.
These debts include loans, credit cards, and any other monthly obligations.
The formula is simple:
DTI = (Total monthly debt payments ÷ Monthly gross income) × 100
Example:
You earn KES 60,000 per month (gross).
You pay KES 15,000 for a Sacco loan, KES 5,000 for a mobile loan, and KES 4,000 for a bank loan.
Total monthly debt = KES 24,000.
DTI = (24,000 ÷ 60,000) × 100 = 40%
That means 40% of your income goes to debt every month.
Lenders use DTI to answer one question:
👉 Can you afford to take on more debt?
A low DTI tells lenders you have room in your budget for new payments.
A high DTI signals that you are already stretched thin.
Therefore, your DTI directly affects your loan limit and approval chances.
Different lenders have different thresholds, but the principle is universal.
A good debt‑to‑income ratio is typically below 30%–40%. Lenders prefer lower ratios because they indicate less risk of default.
| DTI Range | Meaning | Loan Impact |
|---|---|---|
| Below 30% | Excellent – you have low debt burden | Highest loan amounts, best rates |
| 30% – 40% | Good – acceptable for most lenders | Standard approval and limits |
| 40% – 50% | High – some lenders may reject or reduce limits | May need guarantor or collateral |
| Above 50% | Very high – risky borrower | Difficult to get loans, high interest |
In Kenya, many Saccos and banks prefer a DTI below 40% .
For mobile lenders, the threshold may be higher, but interest rates are also much higher.
Different institutions apply DTI differently.
Saccos consider your savings alongside income.
Even with a slightly higher DTI, consistent savings can compensate.
However, a DTI above 50% will still raise concerns.
Banks are stricter. They often cap loan payments at 30–40% of your income.
If your DTI already exceeds that, they may reject your application.
Mobile lenders rarely calculate DTI formally.
Instead, they use your transaction history to estimate repayment capacity.
That’s why they give smaller loans – they only see cash flow, not total debt.
Microfinance institutions may accept DTI up to 50% if the loan is for a business that generates quick cash flow.
💡 Pro tip: Even if a lender doesn’t ask for your DTI, calculate it yourself. It helps you avoid over‑borrowing.
Improving your DTI is simple in concept: reduce debt payments or increase income.
Here’s how to do it quickly.
Target mobile loans, Fuliza, or credit card balances.
These have high interest and use up monthly cash flow.
Example:
Clear a KES 5,000 mobile loan that costs KES 1,000 per month.
Your total monthly debt drops by KES 1,000, improving DTI immediately.
Every new loan increases your monthly payment.
For 3–6 months before a big loan application, stop borrowing.
Combine multiple expensive loans into one cheaper Sacco loan.
This can lower your total monthly payment if you extend the term.
Example:
Three loans with total monthly payments of KES 18,000.
Consolidation into one loan with monthly payment of KES 12,000.
Your DTI improves instantly.
Even a small side hustle can boost your gross income, lowering the DTI percentage.
Example:
Income KES 50,000, debt payments KES 20,000 → DTI = 40%.
Add a side hustle earning KES 10,000 monthly → income = KES 60,000, same debt → DTI = 33%.
Longer repayment terms mean lower monthly payments.
Ask your lender to restructure your existing loans.
Warning: This increases total interest, but it improves your DTI for new loan applications.
If you have savings, using a portion to clear a loan reduces monthly obligations.
In a Sacco, your savings remain available for emergencies after repayment.
Mary had a monthly income of KES 70,000.
Her debts:
Sacco loan: KES 12,000/month
Mobile loan: KES 4,000/month
Bank loan: KES 10,000/month
Total monthly debt = KES 26,000 → DTI = 37% (acceptable but high).
She wanted a larger loan for land.
But her DTI left little room.
She took these steps:
Paid off the mobile loan in full (used savings).
Consolidated the bank and Sacco loans into one Sacco loan at a lower rate.
New monthly payment: KES 18,000.
Total monthly debt dropped to KES 18,000.
DTI = 18,000 ÷ 70,000 = 25.7%.
Now she qualified for the land loan with better terms.
Follow these steps.
Include:
Sacco loan payments
Bank loan instalments
Mobile loan repayments (e.g., Fuliza, M‑Shwari)
Credit card minimum payments
Hire purchase or asset finance payments
Example: KES 10,000 + KES 5,000 + KES 3,000 = KES 18,000.
This is your income before tax.
For salaried workers, use your payslip.
For business owners, use average monthly net profit.
Debt total ÷ gross income × 100 = DTI.
Example: 18,000 ÷ 60,000 × 100 = 30%.
Don’t panic. You can improve it.
Pay off the smallest debt completely.
Stop using credit cards or mobile loans.
Postpone big purchases that would require new loans.
Increase income with a side hustle (see our guide on best side hustles to increase loan eligibility).
Consolidate debts into one lower‑interest loan.
Negotiate with current lenders for lower monthly payments.
Maintain a record of on‑time payments to improve creditworthiness.
Build savings so you can avoid borrowing for small expenses.
Keep debt levels low even after your DTI improves.
❌ Only looking at one debt – DTI considers all debts, not just the loan you’re applying for.
❌ Using cash for debt payments – Lenders can’t see cash payments. Always use bank or M‑Pesa.
❌ Forgetting to include personal guarantees – If you guarantee someone else’s loan, that payment counts toward your DTI.
❌ Applying for new loans while on a repayment plan – Your DTI remains high until loans are fully cleared.
A good debt‑to‑income ratio is typically below 30%–40%. Lenders prefer lower ratios because they indicate less risk of default.
Pay off small debts, avoid new loans, consolidate high‑cost debt, increase your income, or extend loan terms to reduce monthly payments.
Yes, many Saccos consider DTI alongside savings and guarantor strength. A lower DTI helps you qualify for higher loan limits.
Yes, if you can document it with bank statements for at least 3–6 months. Lenders count all verifiable income.
Most lenders prefer below 40%. For Saccos, some accept up to 50% if you have strong savings or guarantors.
Possibly, but with lower amounts and stricter terms. You may need a guarantor, collateral, or a longer repayment period.
Small improvements (paying off a mobile loan) work immediately. Significant DTI reduction may take 3–6 months of disciplined debt repayment and income increase.
Lowering your debt‑to‑income ratio opens doors to better loans, higher limits, and lower interest.
