The Basic Formula for Debt-to-Equity Ratio

The debt-to-equity ratio is calculated by dividing your total debt by your total equity. The formula is: Total Debt ÷ Total Equity = Debt-to-Equity Ratio. This single number tells you how much you owe relative to what you own, and it matters because lenders and creditors use it to decide whether to lend you money and at what interest rate.

To find your total debt, add up every loan and credit balance you carry: mortgage, car loans, student loans, credit card balances, medical debt, personal loans, and any other money you owe. To find your total equity, add up the current value of everything you own minus what you still owe on it. For a house worth $300,000 with a $200,000 mortgage remaining, your equity in that house is $100,000.

Once you have both numbers, divide debt by equity. If you owe $80,000 total and your equity adds up to $120,000, your ratio is 0.67. This means you owe 67 cents for every dollar of equity you own.

Key Takeaways

  • Total debt includes every loan and credit balance you carry, from mortgages to credit cards to medical debt.
  • Total equity is the current market value of what you own minus what you still owe on it.
  • A ratio below 1.0 means you own more than you owe; a ratio above 1.0 means you owe more than you own.
  • Lenders typically prefer to see a ratio below 0.5, though acceptable ratios vary by industry and loan type.
  • Your ratio changes whenever you pay down debt, increase savings, or your assets gain or lose value.

Gathering Your Debt Numbers

Start by listing every debt you carry. Pull your credit report from annualcreditreport.com, which is free and shows most of your debts. Write down the current balance for each account, not the minimum payment or the original loan amount. If you have a mortgage, use the remaining balance shown on your most recent statement, not the original loan size.

Include debts that may not appear on your credit report: medical bills sent to collections, personal loans from family members, money owed to your employer, or business loans if you are self-employed. The goal is to capture what you actually owe, not just what creditors are tracking. Add all these balances together to get your total debt number.

If you are calculating this for a business rather than personal finances, include all liabilities: accounts payable, short-term loans, long-term debt, and any other obligations. The principle is the same—capture everything the business owes.

Calculating Your Total Equity

Equity is what remains after you subtract debt from value. For each asset you own, estimate its current market value and subtract any debt attached to it. Your home may be worth $350,000 today, but if you owe $220,000 on the mortgage, your home equity is $130,000. A car worth $15,000 with a $10,000 loan remaining gives you $5,000 in car equity.

For assets with no debt attached—savings accounts, investment accounts, jewelry, or other possessions—the full current value is your equity. If you have $25,000 in a savings account and $8,000 in investments, that is $33,000 in equity. Be realistic about current value, not what you paid. A used car depreciates; a house may appreciate or depreciate depending on your market.

Add up all your equity across all assets. This total goes in the denominator of your ratio formula. If you own a home with $130,000 equity, a car with $5,000 equity, and have $33,000 in savings and investments, your total equity is $168,000.

Working Through a Real Example

Suppose you are calculating your personal debt-to-equity ratio. Your debts are: mortgage balance of $180,000, car loan of $12,000, credit card balance of $4,500, and student loans totaling $28,000. Your total debt is $224,500.

Your assets are: home worth $320,000 (minus the $180,000 mortgage = $140,000 equity), car worth $18,000 (minus the $12,000 loan = $6,000 equity), savings account with $15,000, and investment account with $9,000. Your total equity is $140,000 + $6,000 + $15,000 + $9,000 = $170,000.

Now divide: $224,500 ÷ $170,000 = 1.32. This ratio of 1.32 means you owe $1.32 for every dollar of equity you own. Most lenders would consider this moderate to high leverage, depending on the type of loan you are seeking.

What Your Ratio Number Means

A ratio below 1.0 is generally considered healthy because it means your assets exceed your debts. A ratio of 0.5 means you owe 50 cents for every dollar you own—this is often the threshold lenders prefer for personal borrowers. A ratio of 1.0 means you owe exactly as much as you own. A ratio above 1.0 means you owe more than you own, which signals higher financial risk.

Context matters. A mortgage lender may accept a ratio of 0.43 (the debt-to-equity threshold used in many lending guidelines), while a credit card company may look at your ratio differently. A business with a ratio of 2.0 might be normal in capital-intensive industries like manufacturing, but the same ratio would be risky for a retail business. Compare your ratio to others in your situation, not to a universal standard.

Your ratio also reflects your financial stage. A recent college graduate with student loans and no home equity may have a ratio above 1.0 and still be on a healthy path. Someone nearing retirement with paid-off assets and minimal debt should have a ratio well below 0.5. The number is a snapshot, not a judgment.

Why Lenders Care About This Ratio

Lenders use your debt-to-equity ratio to measure your ability to repay new debt. If you already owe more than you own, taking on more debt increases the risk that you cannot pay it back. A high ratio signals that you are heavily leveraged—most of your assets are financed by borrowing rather than by money you have already paid for.

When you explore for a mortgage, car loan, or business loan, the lender calculates this ratio from your financial statements or credit report. They compare it to their lending standards. If your ratio exceeds their threshold, they may deny the loan, offer a higher interest rate, or require a larger down payment to lower your leverage.

Your ratio also affects how lenders view your other debts. If you have a high ratio and miss a payment, creditors are more likely to assume you are in financial distress and may be less willing to work with you on a payment plan.

How to Improve Your Ratio

You can lower your debt-to-equity ratio in two ways: reduce debt or increase equity. Paying down your largest debts—usually your mortgage or student loans—directly lowers the numerator. Paying off a $10,000 credit card balance reduces your total debt by $10,000 and improves your ratio when ready.

Increasing equity works on the other side of the equation. Saving money adds to your equity without adding debt. Investing in assets that gain value—a home in an appreciating market, for example—also raises your equity. If your home appreciates $20,000 in value, your equity increases by $20,000 and your ratio improves even if you have not paid down the mortgage.

The fastest path for most people is a combination: pay down high-interest debt like credit cards while building savings. This lowers debt and raises equity at the same time, creating a double improvement in your ratio. Even small monthly payments toward debt reduction compound over time.

Frequently Asked Questions

What if I have negative equity in an asset?

Negative equity occurs when you owe more than an asset is worth—common with cars that depreciate quickly or homes in declining markets. Count the full amount you owe as debt. For equity, use zero, not a negative number. A car worth $12,000 with a $15,000 loan has zero equity in your calculation, and the $15,000 counts as debt.

Should I include my retirement accounts in my equity calculation?

Yes, include the current balance of retirement accounts like 401(k)s and IRAs in your total equity. These are assets you own. However, be aware that lenders may not count them the same way—some will not lend against retirement funds because of tax penalties for early withdrawal. Calculate your ratio both ways to see how lenders might view it.

How often should I recalculate my ratio?

Recalculate whenever you explore for a loan, since lenders will calculate it themselves. For personal tracking, recalculate every six months or annually to watch your progress. Your ratio changes whenever you pay down debt, add to savings, or your assets gain or lose value, so frequent recalculation is not necessary unless you are actively working to improve it.

Is a debt-to-equity ratio of 1.0 bad?

A ratio of 1.0 means you owe as much as you own, which is neither inherently good nor bad—it depends on your age, income, and goals. Someone in their 30s with stable income and a ratio of 1.0 may be fine; someone nearing retirement with the same ratio may need to reduce debt. Most lenders prefer to see ratios below 0.5 for personal borrowers.

Can I have a negative debt-to-equity ratio?

No. Both debt and equity are positive numbers in this formula. If you have no debt, your ratio is zero. You cannot have negative debt or negative equity in the calculation itself, though you can have negative equity in individual assets (which you count as zero in the formula).
