Debt to Equity Ratio: How to Calculate It, What Is Normal and Why Net Debt to EBITDA Is Often Better

The debt to equity formula

Debt to equity = total debt ÷ shareholders' equity
Total debt = short-term borrowings + long-term debt + lease liabilities

Some sources divide total liabilities, not just debt, by equity; that version includes payables, deferred revenue and provisions, which are obligations but not borrowings, and it runs much higher. Know which version a figure uses before comparing it with another. Debt and equity both come from the balance sheet; leases belong in debt since the accounting change that put them there, and preferred stock is usually treated as equity, though a lender would count it as a prior claim.

PackCo, the fictional packaging maker used in the what is ROIC article, has $600 million of debt including leases and $1,150 million of shareholders' equity. Its debt to equity ratio is 600 ÷ 1,150 = 0.52×: for every dollar of owners' capital, lenders have supplied 52 cents.

Worked example: the same business, three times the ratio (illustrative)

Now suppose PackCo borrows $500 million and uses it to buy back shares. The factories, the customers and the operating profit are unchanged. Debt rises to $1,100 million; equity falls to $650 million, because the repurchased shares are deducted from it.

The ratio more than tripled. The company is genuinely more leveraged, so part of that is right, but the size of the jump comes from the denominator shrinking as fast as the numerator grew. Interest coverage, which compares the operating profit with the cost of the debt, fell by about half, a fairer picture of how much riskier the company became. The return on equity formula article shows the mirror image of the same transaction: return on equity jumps while the business stands still.

What counts as normal

As conventions rather than rules, for an industrial, consumer or technology company: below 0.5× is conservative, 0.5× to 1.5× is typical for a mature business, and above 2× is high enough that a downturn becomes a solvency question. Capital-intensive industries with steady revenue run higher: utilities, telecoms and property companies often sit at 1× to 2× or more without strain, because their cash flows are predictable. Banks and insurers are a different world; their liabilities are deposits and policy reserves, their ratios are regulated, and debt to equity in the ordinary sense says nothing useful about them. Within an industry, compare a company with its peers and with its own history, and read a rising ratio as a question: what is the borrowing for, and what cash flow will service it?

Reading the trend, not the level

For a single company the ratio is most useful as a trend. A debt to equity ratio drifting up over five years while operating income is flat means the company is borrowing to stand still, to pay dividends it does not earn or to buy back shares it cannot afford, and each of those is worth a question. A ratio falling as debt is repaid from cash flow is the signature of a business deleveraging after an acquisition or a bad period. Pair the trend with the maturity schedule in the debt note: a stable ratio with half the debt due next year is a different risk from the same ratio with nothing due for a decade. Companies in a downturn also see the ratio rise without new borrowing, as losses and write-downs eat the equity, which is why the level alone can mislead at exactly the moment it matters most.

Why book equity misleads

• Buybacks. A company that has repurchased shares above book value for years can have little or negative equity, giving an enormous or meaningless ratio while carrying modest debt against strong cash flow.
• Write-downs. An impairment removes equity at a stroke and raises the ratio, though the company's debt and cash flow are unchanged.
• Goodwill. Acquisitions add goodwill to equity, so an acquisitive company shows a comfortable ratio on equity that is mostly the premium it paid for other companies. Tangible equity, less goodwill and intangibles, is stricter.
• Intangible businesses. Companies whose value was built by expensed research or marketing carry tiny book equity, so even small borrowings look like heavy leverage.
• Negative equity. The ratio is negative and undefined in meaning; judge the company on cash-flow measures instead.

The ratios lenders use instead

Debt is serviced from cash flow, not from book equity, so the measures that matter compare borrowing with the profit and cash that will repay it:

1. Net debt to EBITDA, debt less cash over operating profit before depreciation: how many years of cash profit the debt represents. PackCo, with $600 million of debt, $200 million of cash and EBITDA of, say, $380 million, is at about 1.1×. The net debt to EBITDA article covers the thresholds.
2. Interest coverage, operating income over interest expense: whether the profit can carry the cost of the debt. Below about 3× is uncomfortable.
3. Net debt to free cash flow: how long repayment would take after the business has funded its own investment.

Debt to equity still earns a place as a quick first look and as a trend indicator for a single company over time. For comparing companies, and for any decision, the cash-flow measures come first; the value trap article shows what happens to a cheap stock when they are ignored, and the enterprise value vs market cap article shows how leverage changes what a share price means. In a stock screen, a debt to equity ceiling is best paired with an interest-coverage floor, and VALYSTR's screener computes both from the filed balance sheet and income statement, leases included.
