About the Debt to Equity Calculator
The debt-to-equity ratio compares what a company owes with what its owners have put in. A higher figure means more of the business is financed with borrowing. This calculator gives the ratio, the share of capital that is debt and, if you add total assets, the equity multiplier. Type debt, equity and optionally total assets and the debt-to-equity ratio appears at once, with a few related figures underneath, and you can copy the result with one tap. The sums run in your browser, so nothing you enter is uploaded.

When you need the debt-to-equity ratio
Investors and lenders use it to measure financial risk. Owners use it to plan how much to borrow.
A ratio near 1 or below is often seen as safe, but capital-heavy industries such as utilities run higher. The equity multiplier shows how much the assets are leveraged.
How the debt-to-equity ratio is worked out
Debt-to-equity = total debt ÷ shareholders' equity. Debt share = debt ÷ (debt + equity). Equity multiplier = total assets ÷ equity. Debt of 300,000 against equity of 200,000 gives a ratio of 1.5, so 60% of the capital is debt. With assets of 500,000, the equity multiplier is 2.5.
Every answer on this page comes from that one rule, so you can check any result by hand with a calculator. The figures shown underneath, such as other units, are conversions of the same answer.

Mistakes to avoid with debt-to-equity ratio

On phone and computer
On a phone, type into the boxes one after another and read the debt-to-equity ratio underneath; Copy result puts it on the clipboard for a message or a note. On a computer the inputs sit on the left and the answer on the right, so you can change one figure and watch the debt-to-equity ratio move. The debt to equity calculator works the same on both.
Checking your debt-to-equity ratio by hand
A good habit is to test the debt to equity calculator with a case you already know. Debt of 300,000 against equity of 200,000 gives a ratio of 1.5, so 60% of the capital is debt. With assets of 500,000, the equity multiplier is 2.5.
If your own figures give a surprising answer, repeat the working yourself: Debt-to-equity = total debt ÷ shareholders' equity. Debt share = debt ÷ (debt + equity). Equity multiplier = total assets ÷ equity. Small differences usually come from rounding, from mixing units, or from a typing slip in one of the inputs. Debt level is just one angle on a company's finances.
