How to Calculate Net Debt

Net debt is total debt less cash and cash equivalents. It measures what a company would still owe if it used every available dollar of cash to pay down borrowings. Net debt is the key term in the bridge between enterprise value and equity value, so getting its components right is essential to any valuation that starts from an EV multiple.

The formula and what counts

The formula is Net Debt = Total Debt - Cash and Equivalents. Total debt includes short-term and long-term borrowings, the current portion of long-term debt, and finance lease liabilities. Cash and equivalents include cash on hand plus highly liquid short-term investments.

Net debt feeds the bridge Equity Value = Enterprise Value - Net Debt. Because enterprise value is capital-structure neutral, subtracting net debt converts it to the value attributable to shareholders. Net debt can be negative, called a net cash position, when cash exceeds debt; that adds to equity value.

Worked example

A company has short-term debt of 50, long-term debt of 350, finance leases of 40, and cash and equivalents of 120. Enterprise value is 1200.

1. Total debt: =50+350+40 returns 440.
2. Net debt: =440-120 returns 320.
3. Equity value: =1200-320 returns 880.
4. If cash were 500 instead: =440-500 returns -60, a net cash position that lifts equity value.

=(50+350+40)-120 returns 320.

Laying it out in a model

Build net debt as a small stacked block so each debt line and the cash offset are visible and the total flows into the equity bridge.

• List each debt instrument on its own row, then a subtotal for total debt.
• Put cash and equivalents as a clearly labeled subtraction line.
• Feed the single net debt cell into the EV-to-equity bridge.
• Pull each figure from the balance sheet so it traces back to a source.

Pitfalls

The most common error is netting the wrong cash. Restricted cash or cash trapped in foreign subsidiaries may not be freely available to repay debt, so including it overstates the offset and understates net debt. Use only cash genuinely available.

Omitting finance lease liabilities, the current portion of long-term debt, or preferred stock understates total debt and overstates equity value. Some analysts also add pension deficits and minority interests in the bridge; be consistent about what belongs in the debt-like bucket. Above all, never type a hardcoded number over a balance-sheet link, or the figure stops updating when the model changes.
