What a Debt Ratio Is and Why You Need It

Your debt ratio is a single number that shows what fraction of your assets are financed by debt. It answers this question: if you sold everything you own and paid off all your debts, how much would be left? A debt ratio of 0.5 means half your assets are funded by borrowing; a ratio of 0.8 means 80 percent are.

Lenders use this number to decide whether to lend you money and at what interest rate. A lower ratio signals that you own more than you owe, which makes you less risky. Banks, credit card companies, and mortgage lenders all look at debt ratio before they say yes or no.

You should calculate your own debt ratio at least once a year, or whenever you take on a major loan or pay off a large balance. It takes about 15 minutes if you have your account statements in front of you.

Key Takeaways

  • Debt ratio equals your total debts divided by your total assets, expressed as a decimal between 0 and 1.
  • You need a current list of everything you owe (mortgages, car loans, credit cards, student loans) and everything you own (cash, investments, property, vehicles).
  • Most lenders prefer to see a debt ratio below 0.6, though the acceptable range depends on the type of loan you are seeking.
  • Your debt ratio changes every time you pay down a balance or acquire a new asset, so recalculate before major financial decisions.

Gather Your Debt Information

Start by listing every debt you carry. Open your most recent statements or log into your online accounts and write down the current balance for each one. Include mortgage balances, car loans, personal loans, credit card balances, student loans, medical debt, and any other money you owe.

Be thorough. A debt you forgot about will skew your calculation. If you have multiple credit cards, list each one separately—do not add them together yet. The same applies to student loans: if you have five federal loans, write down all five balances.

Once you have the list, add all the balances together. This total is your total debt. Write it down clearly; you will need it in the final step.

List Your Assets and Calculate Total Assets

An asset is anything of value that you own. This includes cash in checking and savings accounts, money in retirement accounts (401k, IRA, Roth IRA), stocks and bonds, the current market value of your home, the current market value of your car, and any other property you own outright or partly own.

For your home and car, use the current market value, not what you paid for them. You can find your home's value on Zillow, Redfin, or your property tax assessment. For your car, use the Kelley Blue Book value or the NADA Guides value for your make, model, and condition. If you own a business, include its estimated value.

Do not include items with sentimental value only—jewelry, art, or collectibles—unless you have had them professionally appraised and are confident you could sell them at that price. Stick to things with a clear market value.

Add all your asset values together. This total is your total assets.

Perform the Debt Ratio Calculation

The formula is straightforward:

Debt Ratio = Total Debt ÷ Total Assets

Divide your total debt by your total assets. The answer will be a decimal between 0 and 1. For example, if you owe $150,000 and own $300,000 in assets, your debt ratio is 150,000 ÷ 300,000 = 0.5.

If your total debt is higher than your total assets, your debt ratio will be greater than 1. This is possible and not uncommon—it means you are underwater, or owe more than you own. A ratio of 1.2 means your debts exceed your assets by 20 percent.

Round your answer to two decimal places. A ratio of 0.47 is easier to track than 0.4687.

Understand What Your Ratio Means

A debt ratio below 0.4 is generally considered strong. Most traditional lenders feel comfortable lending to people in this range because the borrower owns substantially more than they owe.

A ratio between 0.4 and 0.6 is acceptable to most lenders, though you may face slightly higher interest rates or stricter terms. Many people fall into this range.

A ratio above 0.6 signals higher risk to lenders. You may still may have access to for loans, but you will likely pay more in interest, face lower credit limits, or encounter stricter approval requirements. A ratio above 0.8 makes borrowing difficult and expensive.

Keep in mind that lenders also look at other numbers—your credit score, your income, and your payment history—so a single high debt ratio does not automatically disqualify you. But it is one of the first things they check.

Common Mistakes to Avoid When Calculating

The most frequent error is forgetting to include all debts. People often overlook medical bills in collections, old personal loans, or a car loan in a spouse's name. Pull your credit report from AnnualCreditReport.com to make sure you have not missed anything.

Another mistake is using the wrong asset values. Do not use the purchase price of your home or car—use what it is worth today. A home you bought for $200,000 ten years ago may be worth $350,000 now, or $150,000, depending on your market. Using the old number will throw off your entire calculation.

Some people include retirement account balances but forget to account for the tax penalty if they withdrew the money early. For the purposes of a debt ratio, include the full balance—lenders see it as an asset you could theoretically access—but understand that the real value is lower if you would actually need to withdraw it.

When to Recalculate Your Debt Ratio

Recalculate your debt ratio before you explore for a major loan—a mortgage, a car loan, or a business loan. Lenders will calculate it themselves, and knowing your number in advance lets you decide whether to explore or wait until you have paid down some debt.

Recalculate once a year as part of your annual financial review. Your ratio changes as you pay down balances and as your assets gain or lose value. Tracking the trend over time shows whether you are moving in the right direction.

You should also recalculate if you receive a large inheritance, sell a property, pay off a major loan, or take on significant new debt. These events shift your ratio enough to matter.

Frequently Asked Questions

Is debt ratio the same as debt-to-income ratio?

No. Debt ratio compares what you owe to what you own. Debt-to-income ratio compares what you owe to how much you earn each month. Lenders use both numbers, but they measure different things. A mortgage lender cares most about debt-to-income; a bank evaluating a business loan cares more about debt ratio.

What if I have a mortgage and a home equity line of credit on the same house?

List both debts separately in your total debt. Use the current market value of the house only once in your total assets. Do not count the house twice. The equity you have in it is the difference between its market value and the sum of all loans against it.

Should I include my spouse's debts and assets if we are married?

If you file taxes jointly or have commingled finances, yes. If you keep finances separate, calculate your own ratio using only your own debts and assets. Some lenders will ask for a joint calculation anyway, so check with them first.

Does paying off a credit card improve my debt ratio?

Yes. When you pay off a credit card, your total debt decreases, which lowers your ratio. Your total assets stay the same, so the improvement is when ready. Paying off a $5,000 credit card balance when you have $200,000 in total assets improves your ratio from 0.50 to 0.475.

What if my debt ratio is above 1?

It means you owe more than you own. This is not uncommon—many people carry a mortgage larger than their home's value, or have student loans that exceed their assets. Focus on paying down debt or increasing assets over time. Most lenders will still work with you, but expect higher interest rates and stricter terms.
