What Is Net Debt?
Net debt measures a company's true indebtedness by offsetting gross borrowings against the cash sitting on its balance sheet. The formula is net debt = total debt - cash and equivalents, where total debt includes short-term borrowings, long-term debt, and the current portion of long-term obligations. A company with $2 billion of debt and $600 million of cash carries $1.4 billion of net debt.
The logic is that cash is effectively negative debt. A buyer acquiring the company could immediately apply the cash against the borrowings, so the economic burden is the net figure rather than the gross one. Companies holding more cash than debt have negative net debt, a position common among large technology firms, which signals substantial balance sheet flexibility.
How Net Debt Is Used
Net debt is the key bridge between equity value and enterprise value: EV = equity value + net debt, plus adjustments for items like preferred stock and minority interest. If a company has a $10 billion market capitalization and $1.4 billion of net debt, its enterprise value is $11.4 billion. Getting this bridge right is essential because EV-based multiples such as EV/EBITDA must pair a capital-structure-neutral numerator with a capital-structure-neutral denominator.
Net debt also drives credit analysis through the net leverage ratio, calculated as net debt divided by EBITDA. A business with $1.4 billion of net debt and $500 million of EBITDA is levered at 2.8x, a level most investment-grade companies would find comfortable, while sponsors in a leveraged buyout might push the same business to 5x or 6x. Credit agreements frequently set covenant thresholds on this exact ratio.
Nuances and Common Pitfalls
Deciding what counts as debt requires judgment. Analysts typically include finance lease obligations and often treat items like unfunded pension liabilities as debt-like, while restricted cash that cannot actually be deployed is excluded from the offset. Convertible bonds add another wrinkle, since they may be treated as debt or as equity depending on whether conversion is in the money.
In interviews, the classic trap is mixing levels: subtracting net debt when moving from enterprise value to equity value but forgetting to add it when going the other way, or pairing an EV multiple with a metric that belongs to equity holders. A candidate who can walk cleanly from market capitalization through net debt to enterprise value, and explain why cash is subtracted along the way, demonstrates command of the most fundamental bridge in valuation.
