Find out what percentage of your income goes to debt payments — and whether lenders will approve your next loan application.
Your Debt-to-Income ratio (DTI) is one of the most important numbers in your financial life. It tells lenders how much of your income is already committed to debt repayments — and tells you whether you have room to borrow more, or whether your debt load is becoming dangerous.

Frequently Asked Questions
Questions About Debt-to-Income Ratio
What is a Debt-to-Income ratio and why does it matter in Nigeria?
Your Debt-to-Income (DTI) ratio is the percentage of your monthly income that goes toward debt payments. It matters because Nigerian banks and licensed lenders use it to decide whether to approve your loan application. A high DTI signals that you are already stretched financially and may struggle to repay new debt. It also matters personally — a DTI above 40% is a warning sign that debt is consuming too much of your income.
What is a good DTI ratio in Nigeria?
Generally, a DTI below 20% is considered excellent. Between 20% and 35% is manageable and most lenders will approve you. Between 35% and 50% is a caution zone where some lenders may decline your application. Above 50% is considered high risk and above 60% is critical — meaning debt is consuming the majority of your income and immediate action is needed.
Should I include loan app payments in my DTI calculation?
Yes, absolutely. Every debt obligation counts — loan apps, bank loans, informal debts from family or friends, cooperative contributions tied to borrowing, and any other regular debt payment. The more complete your picture, the more accurate and useful your DTI result will be.
Should I use gross income or take-home pay for this calculation?
For Nigerian salary earners, entering your gross salary (before deductions) gives you the standard lender-assessed DTI figure. However for a more realistic personal financial picture, entering your actual take-home pay after tax and pension deductions is more useful, since that is the money you actually have available to service debts.
How do I lower my DTI ratio quickly?
There are two ways to lower your DTI: reduce your debt payments or increase your income. On the debt side, use the Debt Snowball method to eliminate smaller debts completely, which removes those payments from your DTI immediately. On the income side, adding a side hustle or negotiating a salary increase raises the denominator in the DTI calculation, reducing the ratio even without changing your debt level.
Can a high DTI affect my mental health?
Yes. A high DTI means a large portion of your income is committed before it even arrives — leaving little room for living expenses, emergencies, or enjoyment. This constant financial tightness is one of the leading causes of financial stress, anxiety, and depression in Nigeria. Reducing your DTI is not just a financial goal — it is a mental health goal too.
Will Nigerian banks check my DTI before approving a loan?
Yes. Most Nigerian commercial banks, microfinance banks, and licensed digital lenders assess your debt obligations relative to your income as part of their credit evaluation. A DTI above 40% to 50% can result in loan rejection or being offered a lower loan amount than you requested. Knowing your DTI before applying helps you understand your approval chances and what lenders will see.
What is the difference between front-end and back-end DTI?
Front-end DTI includes only housing costs (rent or mortgage) as a percentage of income. Back-end DTI includes all debt payments — housing, loans, credit cards, and everything else. This calculator computes your back-end DTI, which is the more comprehensive and commonly used figure for overall financial health assessment.
