Your debt-to-income ratio is the percentage of your gross monthly income that goes toward debt payments

Debt-to-income ratio (often called DTI) is a number lenders use to decide whether to lend you money. It compares how much you owe each month to how much you earn each month, before taxes. If you earn $5,000 gross per month and your debt payments total $1,500 per month, your DTI is 30 percent.

Lenders care about this number because it shows them how stretched your budget already is. A high DTI means less room for a new loan payment. A low DTI means you have breathing room. Most mortgage lenders want to see a DTI below 43 percent, though some will go higher. Credit card companies, auto lenders, and personal loan companies each have their own thresholds.

Your DTI does not measure whether you are a good person or a responsible borrower overall. It is a single financial snapshot. You can have a high DTI and still pay every bill on time, or a low DTI and miss payments. But to a lender deciding whether to take the risk, it is one of the fastest ways to see if you have room to handle another payment.

Key Takeaways

  • Debt-to-income ratio is calculated by dividing your total monthly debt payments by your gross monthly income and multiplying by 100 to get a percentage.
  • Most mortgage lenders prefer a DTI of 43 percent or lower, though some conventional loans accept up to 50 percent.
  • Your DTI includes car loans, student loans, credit card minimum payments, and mortgage or rent payments, but not utilities or groceries.
  • A lower DTI makes you a more attractive borrower and can help you get better interest rates on loans.
  • You can lower your DTI by paying down existing debt or increasing your income, though lenders typically use your current income at the time you explore.

How to calculate your own debt-to-income ratio

Start with your gross monthly income — the money you earn before taxes, not your take-home pay. If you are salaried, divide your annual salary 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. If your income varies month to month, use an average from the last two years or the last 12 months, whichever is lower.

Next, list every monthly debt payment you make. Include the minimum payment on credit cards (not the full balance), car loans, student loans, personal loans, and any mortgage or rent payment. Do not include utilities, insurance premiums, groceries, or other living expenses. Some lenders also count child support or alimony if you are obligated to pay it.

Add all those debt payments together. Divide that total by your gross monthly income. Multiply by 100. That is your DTI percentage. If your debt payments are $1,200 and your gross income is $4,000, your DTI is 30 percent.

What counts as debt in the calculation

Lenders include any payment you are legally obligated to make each month. This covers car loans, student loans (federal and private), personal loans, credit card minimum payments, mortgage payments, and rent if you are renting. If you co-signed a loan for someone else, that payment counts even if they make it — you are still legally responsible.

Credit card debt is tricky. Lenders do not count the full balance you owe; they count the minimum payment shown on your statement. If you owe $5,000 on a credit card with a 2 percent minimum, they count $100 per month, not the full $5,000. This is why paying down credit card balances can lower your DTI even if you still carry debt.

Payments that do not count include utilities, insurance, groceries, gas, phone bills, and other regular living expenses. Medical debt that is not in active collection also typically does not count. If you are unsure whether a specific payment counts, ask the lender directly — rules vary slightly between mortgage companies, credit card issuers, and other creditors.

Why lenders use debt-to-income ratio

A lender's job is to predict whether you will repay them. DTI is one fast way to see if you have room in your budget for a new payment. If you already owe half your income to other creditors, adding another payment becomes risky. If you owe only 20 percent, you have more cushion.

DTI is not the only thing lenders look at. They also check your credit score, your payment history, your savings, and your employment stability. But DTI is one of the first filters. If your DTI is too high, some lenders will reject you before they even pull your credit report. Others will offer you a loan at a higher interest rate to compensate for the higher risk.

The threshold varies by loan type. Mortgage lenders are typically stricter because mortgages are large, long-term commitments. Credit card companies are often more flexible because credit lines are smaller and shorter-term. Auto lenders fall somewhere in the middle. Understanding what threshold matters for the loan you are seeking helps you know whether you have a realistic shot.

How to lower your debt-to-income ratio

You have two levers: reduce your debt payments or increase your income. Reducing debt is usually faster. Paying off a car loan or credit card balance lowers your monthly obligations when ready. Paying down credit card balances is especially effective because it lowers both the minimum payment and your overall debt load.

Increasing income takes longer but is permanent. A raise, a second job, or a side income source all raise your gross monthly income, which lowers your DTI ratio. However, lenders typically verify income through recent tax returns or pay stubs, so a brand-new income source may not count yet. Ask the lender what documentation they need before you rely on new income.

Some people try to lower their DTI by not explore for new credit for a few months before explore for a mortgage or large loan. This does not work. Your DTI is based on debts you already have, not on debts you might take on. The only way to change it is to pay down existing debt or earn more money.

Debt-to-income ratio and mortgage approval

Mortgage lenders use DTI as a major approval factor. Most conventional mortgages require a DTI of 43 percent or lower. Some lenders will go up to 50 percent if you have a strong credit score, a large down payment, or significant savings. Federal Housing Administration (FHA) loans sometimes allow DTI up to 50 percent. Veterans Affairs (VA) loans have no official DTI limit but typically expect 41 percent or lower.

When a mortgage lender calculates your DTI, they include your new mortgage payment in the calculation. So if you earn $5,000 per month, have $800 in existing debt payments, and are explore for a mortgage with a $1,500 monthly payment, your new DTI would be ($800 + $1,500) / $5,000 = 46 percent. Many lenders would reject this process because it exceeds their 43 percent threshold.

This is why people sometimes need to pay down debt before they can may have access to for a mortgage. Paying off a car loan or credit card can free up enough room in the DTI calculation to make the mortgage payment fit within the lender's limits.

Debt-to-income ratio versus credit score

DTI and credit score are different measures. Your credit score reflects your payment history, how long you have had credit, and how much of your available credit you are using. Your DTI reflects only your current monthly obligations relative to your income. You can have a high credit score and a high DTI, or vice versa.

A person who pays every bill on time but carries a lot of debt might have a high credit score but a high DTI. A person who recently missed payments but has paid off most of their debt might have a lower credit score but a lower DTI. Lenders look at both numbers because they measure different things.

If you are trying to improve your chances of loan approval, focus on both. Pay down debt to lower your DTI, and make on-time payments to improve your credit score. Both matter, and both take time.

Frequently Asked Questions

Does rent count toward my debt-to-income ratio?

Yes, most lenders count rent as a debt payment when calculating DTI. If you are renting and explore for a mortgage, they include your current rent payment. If you are already a homeowner explore for a second mortgage or home equity line of credit, they include your mortgage payment. Some lenders count rent; others do not. Ask before you explore.

What if my income varies month to month?

Lenders typically average your income over the last two years or the last 12 months, whichever is lower. If you are self-employed or work on commission, bring tax returns and recent bank statements to show your typical earnings. Lenders want to see a pattern, not a single high month.

Can I lower my DTI by paying off a credit card in full?

Yes, but only if you close the account or stop using it. If you pay off the balance but keep the account open and active, the lender may still count a minimum payment based on your credit limit. Closing the account removes it from the calculation entirely. However, closing old accounts can lower your credit score, so weigh the trade-off.

Do student loans count if I am on an income-driven repayment plan?

Yes, but the amount counted depends on your plan. Lenders use the payment amount shown on your loan statement or calculate it based on your income and family size. If you are in deferment or forbearance, some lenders count a payment anyway; others do not. Check with your lender about how they handle your specific situation.

What is a good debt-to-income ratio?

Below 36 percent is considered good by most lenders. Below 20 percent is excellent. Between 36 and 43 percent is acceptable for mortgages but may limit your options or raise your interest rate. Above 43 percent makes mortgage approval difficult. For other types of loans, thresholds vary — credit card companies and auto lenders are often more flexible.
