What your debt-to-income ratio is and why lenders look at it

Your debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes toward debt payments. Lenders use it to decide whether you can afford a consolidation loan, a mortgage, or any other credit. A lower ratio means you have more money left over each month after debt; a higher ratio means debt is consuming more of what you earn.

Most lenders want to see a DTI below 43 percent, though some consolidation loan programs accept ratios up to 50 percent. If your ratio is above 43 percent, you may still find lenders willing to work with you, but you will face higher interest rates or stricter terms. Understanding your own number before you shop for a loan tells you what to expect and helps you decide whether consolidation makes sense for your situation.

Key Takeaways

  • Debt-to-income ratio is calculated by dividing your total monthly debt payments by your gross monthly income, then multiplying by 100 to get a percentage.
  • Gross monthly income includes salary, wages, self-employment income, Social Security, disability payments, and alimony — before taxes or deductions.
  • Monthly debt payments include credit cards (minimum payment), car loans, student loans, mortgages, and personal loans, but not utilities or groceries.
  • Most lenders prefer a DTI below 43 percent, though consolidation loan programs sometimes work with borrowers at 50 percent or higher.
  • You can lower your DTI by paying down debt, increasing income, or both — consolidation itself does not lower your ratio unless the new loan has a lower monthly payment.

How to add up your monthly debt payments

Start by listing every debt you currently owe. Include credit card minimum payments (not the full balance), car loans, student loans, mortgages, personal loans, medical debt in repayment plans, and any other loan with a monthly payment. Do not include utilities, groceries, insurance premiums, rent (unless you are calculating a mortgage process), or childcare — those are living expenses, not debt payments.

Write down the minimum or scheduled payment for each one. If you have multiple credit cards, use the minimum payment shown on each statement, not the full balance. For a car loan or student loan, use the payment amount from your loan documents or statement. Add all these payments together to get your total monthly debt payments.

If you are self-employed or your income varies, use an average of the last two years of tax returns or the most recent year if that is higher. If you receive income from multiple sources — a job plus freelance work, or a pension plus part-time wages — add them all together before taxes.

How to calculate your gross monthly income

Gross income is what you earn before taxes, Social Security, or any other deduction. If you are salaried, take your annual salary and divide by 12. If you are paid hourly, multiply your hourly rate by the number of hours you typically work per week, then multiply by 52 weeks and divide by 12.

Include all income sources: wages from a job, self-employment income, Social Security, disability payments, pension income, alimony or child support received, rental income, or investment income. Use the amount before any taxes are taken out. If your income is irregular or seasonal, use an average of the last two years of tax returns.

Do not include money from loans, gifts, or one-time payments. Do not count income from a spouse or partner unless you are explore for a joint loan — lenders calculate DTI on the individual borrower's income unless the process is joint.

The formula and what the number means

The calculation is straightforward: divide your total monthly debt payments by your gross monthly income, then multiply by 100 to convert to a percentage.

(Total monthly debt payments ÷ Gross monthly income) × 100 = Debt-to-income ratio

For example: if your gross monthly income is $4,000 and your total monthly debt payments are $1,200, your DTI is 30 percent. If your gross monthly income is $3,500 and your debt payments are $1,750, your DTI is 50 percent.

A DTI of 30 percent or below is considered good by most lenders. Between 30 and 43 percent is acceptable, though you may pay a higher interest rate. Above 43 percent, many traditional lenders will decline you, though some consolidation loan companies will still work with you at higher rates. Above 50 percent, options narrow significantly.

Why consolidation does not automatically lower your ratio

A common misconception is that consolidating debt lowers your DTI. It does not — unless the new loan has a lower monthly payment than the sum of your old payments. Consolidation combines multiple debts into one, which simplifies your payments and usually lowers your interest rate, but the total amount you owe stays the same.

If you consolidate $15,000 in credit card debt at 20 percent interest into a personal loan at 10 percent interest, your monthly payment will likely drop. That lower payment does lower your DTI. But if you consolidate and extend the repayment term to keep payments low, you pay more interest overall. The DTI improvement is real, but it comes from the lower payment, not from the consolidation itself.

Before you explore for a consolidation loan, calculate what your new monthly payment would be and recalculate your DTI with that number. That shows you whether consolidation will actually improve your ratio enough to matter for future borrowing.

How to lower your debt-to-income ratio

The two levers are income and debt. Increasing your income raises the denominator, making the ratio smaller. Paying down debt lowers the numerator, also making the ratio smaller. The fastest results usually come from doing both.

On the income side: a raise, a second job, or increased hours at your current job all count. If you are self-employed, documenting higher income on your next tax return will improve your ratio for future loan applications. On the debt side: paying more than the minimum on any loan reduces your monthly payment obligation. Paying off a credit card or small personal loan entirely removes that payment from your calculation.

If you are considering a consolidation loan specifically to lower your DTI, focus on whether the new loan's monthly payment is lower than what you are paying now. If it is not, consolidation will not help your ratio. In that case, paying down debt before explore for any new loan is the better strategy.

Frequently Asked Questions

Does my spouse's income count toward my DTI?

Only if you are explore for a joint loan. If you are explore alone, lenders calculate your DTI using only your income. If you explore jointly, they typically add both incomes and both debts together. Check with the lender about their specific policy, as some treat spousal income differently depending on community property laws in your state.

Should I include my mortgage payment in my DTI?

Yes, if you are calculating your overall DTI for a consolidation loan or other credit. Include your full mortgage payment (principal, interest, taxes, and insurance). If you are explore for a mortgage, lenders calculate a separate "housing ratio" using only housing costs, and a "back-end ratio" using all debt. Ask the lender which number they need.

What if I am about to pay off a debt — should I count it?

Count it as long as you are still making payments. Once the debt is paid off and the account is closed, you can remove it from your calculation. If you are close to paying something off, you can show the lender a payoff letter to demonstrate the payment will disappear soon, which may help your case even if the current ratio is high.

Does my DTI include rent or utilities?

No. Rent and utilities are living expenses, not debt payments. They do not count toward your DTI. However, if you are explore for a mortgage, the lender will look at your housing costs separately as part of the approval decision, even though they are not part of your DTI calculation.

Can I lower my DTI by paying off credit cards?

Yes, but only if you close the account or stop using it. Paying down the balance does not lower your DTI unless you also reduce the minimum payment. Many lenders calculate minimum payments as a percentage of the balance, so paying off a card entirely removes that payment from your ratio. Paying it down partway may lower the minimum slightly, but the effect is usually small.
