Net debt is a company’s interest-bearing debt minus its cash and cash equivalents. It shows how much borrowing would remain if the company used its liquid funds to pay down what it owes. A business with $300 million of loans and bonds and $100 million in the bank has net debt of $200 million. If cash exceeds debt, net debt is negative, which is usually described as a net cash position.

What net debt measures

Total debt counts every borrowed dollar. Net debt asks a narrower question: how much of that borrowing is not already covered by cash on hand? Two companies can each owe $500 million, but one with $400 million of cash is in a very different position from one with $20 million.

That is why net debt comes up in credit analysis, valuation and acquisitions. Lenders and rating analysts use it to gauge leverage. Equity investors use it to move from the value of the whole business to the value of the shares. During downturns, stakeholders watch it closely because it indicates how much room a company has before it must refinance or raise new capital.

How to calculate net debt

The formula

Net debt = Short-term debt + Long-term debt − Cash and cash equivalents

All three inputs come from the balance sheet, with detail in the debt and cash notes:

• Short-term debt: borrowings due within 12 months, such as short-term bank loans, commercial paper issued by the company, drawn revolving credit lines and the current portion of long-term debt.
• Long-term debt: obligations due after one year, such as bonds, term loans and notes, net of the current portion so nothing is counted twice.
• Cash and cash equivalents: cash in the bank plus highly liquid investments with original maturities of roughly 90 days or less, such as Treasury bills, certificates of deposit and money market holdings.

Net debt focuses on financing obligations. Operating liabilities such as accounts payable, accrued wages and deferred revenue are generally left out because they arise from day-to-day trading rather than borrowing.

Choices that change the number

Because no single accounting standard defines net debt, companies and analysts make different choices:

• Marketable securities: short-term investments that can be sold quickly are often subtracted alongside cash. Longer-dated or illiquid investments usually are not.
• Restricted cash: cash pledged as collateral, held in escrow or otherwise unavailable is normally excluded, since it cannot repay debt.
• Lease liabilities: since lease accounting moved most leases onto the balance sheet (IFRS 16 and ASC 842), some measures include lease liabilities and some do not. This can move net debt materially for retailers, airlines and other lease-heavy businesses.
• Other debt-like items: preferred stock, unfunded pension obligations and earnout liabilities are sometimes added, especially in valuation and deal work.

When a company publishes its own net debt figure, it is typically a non-GAAP measure with a reconciliation showing what was included. Compare companies only after putting them on the same definition.

Worked example

The following figures are hypothetical, in millions of dollars.

Company A

• Short-term borrowings: $40
• Current portion of long-term debt: $10
• Long-term debt: $250
• Cash and cash equivalents: $60
• Short-term marketable securities: $20
• Restricted cash: $5

Using cash only: 40 + 10 + 250 − 60 = $240 million net debt.

Subtracting marketable securities as well: 40 + 10 + 250 − 60 − 20 = $220 million.

The restricted $5 million is excluded in both versions. The $20 million gap between the two results is purely a definitional choice.

Company B

• Short-term debt: $20
• Long-term debt: $280
• Cash and cash equivalents: $180

Net debt: 20 + 280 − 180 = $120 million.

Both companies carry $300 million of total debt. On a total debt basis they look identical. On a net basis, Company B has half the leverage of Company A because its cash covers a larger share of what it owes.

Interpreting the result

Positive net debt means borrowing exceeds liquid funds. That is normal for most established companies, and its significance depends on earnings, cash flow and industry. Capital-intensive sectors such as utilities, telecommunications and mining tend to carry more debt than software or service firms. A rising figure may reflect heavy investment in plants or acquisitions that are expected to pay off later, so the reason for the debt matters as much as the size.

Negative net debt means cash exceeds debt. It gives a company flexibility to invest, buy back shares, make acquisitions or ride out a downturn without new financing. It can also mean capital is sitting idle, earning less than the business could earn by reinvesting it or returning it to shareholders.

Net debt of zero means cash and debt offset exactly. The company still owes creditors and pays interest; it could, in principle, retire its debt with the cash it holds.

How net debt is used in analysis

Enterprise value

Enterprise value measures the value of the whole business to all capital providers:

EV = Market capitalization + Net debt + Preferred equity + Minority interest

If Company A has a market capitalization of $500 million and no preferred stock or minority interests, its EV is $500 + $240 = $740 million. Working in the other direction, a discounted cash flow model usually produces an enterprise value first, and net debt is subtracted to reach equity value.

This also explains how acquisitions are priced. A buyer acquiring the shares takes on the company’s debt and receives its cash. Deals are therefore often agreed on a “cash-free, debt-free” basis: the headline price reflects enterprise value, and the seller’s proceeds are reduced by estimated net debt at closing. After closing, the parties calculate the actual net debt from the completion accounts and settle any difference.

Leverage ratios

• Net debt to EBITDA: net debt divided by annual EBITDA, read as the approximate number of years of operating earnings needed to repay net debt. With EBITDA of $80 million, Company A’s ratio is 240 ÷ 80 = 3.0x. A rule of thumb treats readings below about 3x as comfortable and above about 5x as heavy, but acceptable levels differ widely by industry, and loan covenants often set specific limits.
• Net debt to equity (net gearing): net debt divided by shareholders’ equity. If Company A has $400 million of equity, net gearing is 240 ÷ 400 = 0.6, or 60%. Higher gearing can amplify returns on equity when borrowed money earns more than it costs, and amplifies losses when it does not.
• Net debt to free cash flow: net debt divided by annual free cash flow. With $30 million of free cash flow, Company A would need about 240 ÷ 30 = 8 years to clear net debt, assuming every dollar of free cash flow went to repayment and nothing else changed.

Net interest coverage

Standard interest coverage divides EBIT by interest expense. A net version divides EBIT by interest expense minus interest income, reflecting that income on cash balances offsets part of the cost of debt. A company with large cash holdings and large debt can look weaker on the gross measure than on the net one.

Limitations of net debt

• It is a snapshot. Net debt is measured on the balance sheet date. Seasonal businesses may hold peak cash at year end, and companies can time repayments or collections around reporting dates.
• Not all cash is spare. A business needs some cash to operate. Cash held in foreign subsidiaries may face tax or legal barriers to moving it. Subtracting every dollar of cash can overstate repayment capacity.
• It ignores debt terms. Maturity dates, interest rates, fixed versus floating pricing and covenants are invisible in a single figure. Two companies with identical net debt can face very different refinancing risk.
• It says nothing about cash generation. Net debt is only meaningful alongside earnings and cash flow, which is why it is usually expressed as a ratio.

Net debt vs. related terms

Total debt vs. net debt: total debt is the gross amount of borrowings. Net debt subtracts cash and equivalents. Total debt is always zero or more; net debt can be negative.

Net debt vs. net borrowing: net debt is a balance at a point in time. Net borrowing (or net new borrowing) is a flow over a period: debt issued minus debt repaid. On a cash flow statement, a line such as “issuance/(reduction) of debt, net” shows this flow. A positive figure means the company borrowed more than it repaid; a figure in parentheses means a net reduction in debt.

Net debt vs. net worth: net worth (shareholders’ equity) is all assets minus all liabilities. Net debt considers only financial debt and liquid assets.

The Bottom Line

Lenders, rating analysts, equity investors and deal makers rely on net debt to judge leverage and to bridge enterprise value and equity value. Because no single standard defines it, comparisons work only after putting companies on the same treatment of securities, leases and restricted cash. The figure is a snapshot that hides debt terms and cash generation, so it is most useful when read alongside earnings and cash flow ratios.
