Gross margin and EBITDA margin measure profit at different cost boundaries. Compare both from the same business-unit P&L, trace depreciation correctly, and reconcile the difference before deciding which unit performs better.
Gross margin vs EBITDA margin compares two different cost boundaries: gross margin stops after cost of sales, while EBITDA margin also reflects operating expenses before depreciation and amortization. A business unit can lead on gross margin and trail on EBITDA margin because it requires more sales or administrative support. Calculate both from the same P&L before treating either ranking as the whole answer.
Gross margin = (Net revenue − Cost of sales) / Net revenue
EBITDA margin = (Net income + Income tax expense + Net interest expense + Depreciation and amortization) / Net revenue
The first measure asks how much revenue remains after the costs classified as producing or acquiring what was sold. The IRS explanation of gross profit subtracts returns and allowances before deducting cost of goods sold. It supports the basic calculation; use your company's accounting policy to determine the cost boundary in its reporting P&L.
The second asks how much earnings remain before financing, income taxes and depreciation and amortization. The SEC's EBITDA guidance, Questions 103.01 and 103.02, defines earnings as GAAP net income and calls for reconciliation to net income when EBITDA is presented as a performance measure. EBITDA is a non-GAAP measure, so keep its definition visible.
| Question | Gross margin | EBITDA margin |
|---|---|---|
| What is the numerator? | Revenue less cost of sales | Net income with the specified add-backs |
| Are selling and administrative expenses included? | Generally below gross profit | Included, except their depreciation and amortization |
| Is production depreciation included? | Yes, when classified in cost of sales | Added back |
| Are interest and income taxes included? | Below gross profit | Excluded through the reconciliation |
| What decision does it support? | Pricing, sourcing and product mix | Operating expense coverage and unit economics at a broader cost boundary |
The base definitions and classification detail belong in gross profit margin and EBITDA margin. The comparison here is the bridge between them.
Bring the closed P&L with period, business unit, account, account description and amount. Map accounts to revenue, cost of sales, selling and administrative expenses, depreciation and amortization, interest, and income taxes. Preserve the original account references beside the mapping so someone can trace each subtotal back to the ledger.
Depreciation needs a second label identifying where it was originally charged. Factory depreciation in cost of sales and office depreciation in administrative expenses both enter the EBITDA add-back, but only the factory amount already reduced gross profit.
Use the same period, currency and consolidation scope. For an internal unit comparison, operating income plus depreciation and amortization equals EBITDA only when no other nonoperating items create a difference. If there are investment gains or other nonoperating amounts, extend the reconciliation rather than silently dropping them.
Consider a fictional US industrial-components company with Standard and Specialty units for the quarter ended September 30, 2026. Expenses below are positive amounts to subtract; the depreciation rows are components of the expenses shown, not additional cash payments. There are no nonoperating gains or losses in this example.
| P&L step | Standard (USD) | Specialty (USD) | Company (USD) |
|---|---|---|---|
| Net revenue | 1,200,000 | 800,000 | 2,000,000 |
| Cost of sales excluding depreciation | 720,000 | 400,000 | 1,120,000 |
| Depreciation in cost of sales | 40,000 | 20,000 | 60,000 |
| Total cost of sales | 760,000 | 420,000 | 1,180,000 |
| Gross profit: revenue less total cost of sales | 440,000 | 380,000 | 820,000 |
| Selling and administrative costs excluding D&A | 250,000 | 270,000 | 520,000 |
| D&A in selling and administrative costs | 10,000 | 20,000 | 30,000 |
| Operating income | 180,000 | 90,000 | 270,000 |
| Add back total D&A | 50,000 | 40,000 | 90,000 |
| EBITDA | 230,000 | 130,000 | 360,000 |
| Gross margin | 36.67% | 47.50% | 41.00% |
| EBITDA margin | 19.17% | 16.25% | 18.00% |
Dollar calculations are exact; displayed percentages are rounded to two decimal places. Standard gross profit is $1,200,000 − $760,000 = $440,000. Its EBITDA is $180,000 + $50,000 = $230,000. Divide each profit measure by Standard's own revenue to obtain the two margins.
Specialty has the stronger gross margin but the weaker EBITDA margin. Its selling and administrative costs consume more of its revenue, even after the related D&A is excluded. That is a reason to investigate the support required by its customers and products, rather than assuming its premium gross margin guarantees superior operating performance.
In this example, the bridge is:
EBITDA = Gross profit − Selling and administrative costs excluding D&A + D&A included in cost of sales
At company level, $820,000 − $520,000 + $60,000 = $360,000. The $30,000 of administrative D&A is absent from the expense deduction, so adding it again would overstate EBITDA.
The margin gap is 41.00% − 18.00% = 23.00 percentage points. It equals ($520,000 − $60,000) / $2,000,000. Calling that gap simply the overhead ratio would miss the production depreciation already charged above gross profit.
Confirm the company measure independently:
| Net-income reconciliation | Amount (USD) |
|---|---|
| Operating income from the unit table | 270,000 |
| Less net interest expense | 40,000 |
| Income before tax | 230,000 |
| Less income tax expense | 50,000 |
| Net income | 180,000 |
| Net income + interest + tax + total D&A | 360,000 |
Both routes reach the same EBITDA. Unit revenues and profits also sum to the company figures. Divide the summed profits by summed revenue; an unweighted average of unit percentages gives each unit equal influence despite different sales volumes.
Use gross margin when the decision concerns pricing, purchase costs or product mix. Use EBITDA margin when comparing how much revenue survives the broader operating cost structure, with allocations and nonoperating items made explicit. Review capital spending separately because excluding depreciation does not make equipment replacement unnecessary.
Keep discretionary exclusions separate: adjusted EBITDA margin addresses those changes, while an EBITDA margin bridge follows the movement between periods. Neither should replace the reported-to-EBITDA reconciliation above.
Upload your business-unit P&L and depreciation detail, or bring a Google Sheet; Covirage maps the columns, and its tools compute and check the figures against the supplied rows. The external AI model explains the comparison with every figure traced to its rows. Create a free Covirage account and bring a sample of your own export; creating the account takes about a minute.

Gross margin is often higher because EBITDA also reflects selling and administrative expenses. That ordering is not guaranteed. Depreciation included in cost of sales reduces gross profit but is added back in EBITDA, and nonoperating income can also affect the comparison.
Yes. Better pricing or lower product costs can improve gross margin while additional selling, administrative or other operating expenses reduce EBITDA margin. A reconciliation using the same revenue base shows whether the product improvement paid for the additional overhead.
No. EBITDA excludes depreciation and amortization, but revenue may remain uncollected and expenses may remain unpaid. Inventory purchases, capital expenditures, interest and taxes also affect cash. Use a cash flow statement and working-capital records when the decision concerns available cash.
Show the allocation policy with the comparison. An unallocated unit result helps assess local performance, while an allocated result shows its share of corporate support. Keep the two views separately labeled and reconcile them to the company total before ranking units.
