What this calculator does
Find out how much a company owes for every dollar its owners have in the business. The debt-to-equity ratio compares what the company owes (its liabilities) with the owners' stake (shareholders' equity). Equity is the money owners have put in and kept in the business. A ratio of 1.5 means there is $1.50 of liabilities for every $1 of shareholders' equity. It's a quick measure of leverage. Leverage means how much the company leans on borrowed money and other debts, rather than owners' money, to pay for what it owns.
The calculator divides total liabilities by total shareholders' equity. What a company owns (its assets) always equals what it owes plus the owners' stake. So the same two numbers also give two more figures. The debt-to-assets ratio is the share of the assets paid for by liabilities. The equity multiplier shows how many dollars of assets each dollar of equity supports.
Where it's used
Why this math matters outside the classroom:
- Measuring leverage. A business with $300,000 of liabilities and $200,000 of equity has a debt-to-equity ratio of 1.5.
- Balance sheet check. Analysts confirm that total assets equal liabilities plus equity, $500,000 in that example.
- Debt-to-assets. The same company finances 60% of its $500,000 of assets with debt, since 300,000 ÷ 500,000 = 0.6.
- Accounting classes. Students compute leverage ratios from a sample balance sheet and compare two companies in the same industry.

How to use it
- Find total liabilities on the company's balance sheet.
- Find total shareholders' equity on the same balance sheet. It must be a positive number.
- Enter both figures.
- Read the debt-to-equity ratio, the debt-to-assets percentage and the equity multiplier.
What the inputs mean
- Total liabilities
- This version uses all liabilities. That includes accounts payable (bills owed to suppliers) and other debts that charge no interest. Some analysts use only debt that charges interest instead. You can enter that figure here. But then the debt-to-assets result no longer matches the balance sheet total.
- Total shareholders' equity
- Shareholders' equity is sometimes called owners' equity or net worth. If it's zero or negative, the company owes more than its assets are worth. Then the ratio can't be read in a useful way, so the calculator asks for a positive figure.
Formula and method
debt-to-equity = total liabilities ÷ shareholders' equity total assets = total liabilities + shareholders' equity debt-to-assets = total liabilities ÷ total assets × 100 equity multiplier = total assets ÷ shareholders' equity = 1 + debt-to-equity
Every asset on a balance sheet is paid for in one of two ways. Either lenders and others the company owes paid for it (liabilities), or the owners did (equity). The debt-to-equity ratio compares those two sources head to head. Debt-to-assets compares liabilities with the total.
The ratios are linked, so knowing any one of them tells you the others. D/E is short for debt-to-equity. A D/E of 1.5 always means liabilities pay for 60% of assets, with an equity multiplier of 2.5. The equity multiplier is also the leverage part of the DuPont breakdown. That's a common way to split return on equity (the owners' yearly return) into its parts.
Worked example
A company's balance sheet shows it owes $600,000 in total liabilities. The owners' stake, its shareholders' equity, is $400,000.
- Debt-to-equity: $600,000 ÷ $400,000 = 1.50.
- Total assets: $600,000 + $400,000 = $1,000,000.
- Debt-to-assets: $600,000 ÷ $1,000,000 × 100 = 60%.
- Equity multiplier: $1,000,000 ÷ $400,000 = 2.50.
Result: The company has $1.50 of liabilities for every $1 of equity. Debts pay for 60% of what it owns. Each dollar the owners have in it supports $2.50 of assets.
Understanding the result
A higher ratio means more leverage. Borrowing can boost returns to owners when the business earns more on its assets than its debt costs. But it also raises fixed payments. And it raises the risk of trouble when sales fall.
What counts as high varies a great deal by industry. Utilities and banks often carry large liabilities compared with their equity. Many software and service companies carry very little. Compare a company with similar companies and with its own history, not with a single number.
A ratio below 1 means owners have paid for more of the assets than lenders have. That points to a careful, low-risk balance sheet. It may also mean the company isn't using cheap borrowing it could afford.
Assumptions and limitations
- Both figures come from the same balance-sheet date.
- Total assets are taken as liabilities plus equity. That's the basic accounting equation, which always holds.
- Ratios aren't rounded while the calculator works. They're shown to two decimal places.
- The values on the books (book values) can differ greatly from market values, what things would sell for today. That's especially true for older assets, or companies whose value is mostly things you can't touch, like brands.
- Some obligations, such as certain guarantees, may not appear in total liabilities.
- The ratio doesn't tell you whether the company can afford its payments. Interest coverage (how many times profit covers interest) and cash flow measures answer that.
Frequently asked questions
What is a good debt-to-equity ratio?
There's no single answer; it depends on the industry. Businesses that need lots of costly equipment, such as utilities, often carry far more liabilities for their equity. Businesses that own little, such as software firms, carry less. A ratio that's rising quickly, or that's far above similar companies, deserves a closer look.
Should I use total liabilities or only debt?
Both versions are common. Total liabilities give the broadest view and tie neatly to total assets. Using only debt that charges interest focuses on borrowing that costs money and has fixed repayments. Whichever you pick, use the same one every time you compare companies.
What does negative equity mean?
It means liabilities are larger than assets, so the owners' stake is below zero on paper. The debt-to-equity ratio turns negative or can't be worked out, and it stops being a useful comparison. That's why the calculator requires positive equity. Debt-to-assets above 100% is another way of showing the same situation.
How is the equity multiplier related to D/E?
The equity multiplier is total assets divided by equity. Assets equal liabilities plus equity, so the multiplier always equals 1 plus the debt-to-equity ratio.
How this calculator is checked
Method: Standard balance-sheet leverage ratios: liabilities ÷ equity, liabilities ÷ assets, assets ÷ equity, with assets = liabilities + equity. The calculation is covered by automated tests with known reference values and edge cases. Last updated 2026-10-18. Found a problem? Tell us.
