Accounting EBITDA Per-Unit Formula
Learn how EBITDA per unit, total EBITDA, and EBITDA margin are estimated from per-unit revenue and operating costs.
This calculation estimates the operating earnings contributed by each unit sold before interest, taxes, depreciation, and amortization. It helps evaluate unit economics by combining net revenue, recurring operating income, direct costs, and allocated operating expenses on a consistent per-unit basis.

EBITDA per Unit
Where:
Start with net revenue from one unit, add recurring operating income related to that unit, then subtract direct costs and operating expenses. The remaining amount is estimated EBITDA per unit.

Step-by-Step Calculation
Calculate total revenue
Multiply net revenue per unit by the number of units sold.
totalRevenue = unitsSold * revenuePerUnit
Calculate total direct costs
Multiply direct cost of goods sold per unit by sales volume.
totalCostOfGoodsSold = unitsSold * costOfGoodsSoldPerUnit
Calculate total operating expenses
Multiply the operating expense allocated to each unit by sales volume.
totalOperatingExpenses = unitsSold * operatingExpensesPerUnit
Calculate other operating income
Multiply recurring other operating income per unit by sales volume.
totalOtherOperatingIncome = unitsSold * otherOperatingIncomePerUnit
Calculate EBITDA per unit
Combine the per-unit revenue and cost figures to estimate operating earnings for one unit.
ebitdaPerUnit = revenuePerUnit + otherOperatingIncomePerUnit - costOfGoodsSoldPerUnit - operatingExpensesPerUnit
Calculate total EBITDA
Subtract total direct costs and operating expenses from total revenue plus other operating income.
totalEbitda = totalRevenue + totalOtherOperatingIncome - totalCostOfGoodsSold - totalOperatingExpenses
Calculate EBITDA margin
Divide EBITDA per unit by revenue per unit and convert the result to a percentage.
ebitdaMargin = (ebitdaPerUnit / revenuePerUnit) * 100
Example: EBITDA for a product line
Total revenue
10,000 × $50.00
$500,000
Total cost of goods sold
10,000 × $22.00
$220,000
Total operating expenses
10,000 × $15.00
$150,000
EBITDA per unit
$50.00 + $1.00 − $22.00 − $15.00
$14.00 per unit
Total EBITDA
10,000 × $14.00
$140,000
EBITDA margin
($14.00 ÷ $50.00) × 100
28.0%
Final Result
Estimated EBITDA is $14.00 per unit, total EBITDA is $140,000, and EBITDA margin is 28.0%.
Assumptions
- ✓Revenue per unit is net of applicable discounts, returns, and allowances.
- ✓Cost of goods sold and operating expenses exclude depreciation and amortization.
- ✓Other operating income is recurring, operating-related, and measured consistently per unit.
- ✓All per-unit figures and units sold relate to the same accounting period.
- ✓Operating expense allocations are representative of the units being evaluated.
Limitations
- !EBITDA definitions and expense classifications may vary between businesses, reporting frameworks, lenders, and analysts.
- !Per-unit allocations may not reflect fixed costs accurately at very different sales volumes.
- !The calculation does not include interest, taxes, depreciation, amortization, capital expenditure, or working-capital effects.
- !One-time income, restructuring costs, and other non-recurring items can make reported results differ from this estimate.
Common Mistakes to Avoid
Including depreciation or amortization in cost of goods sold or operating expenses.
Using gross list price rather than net revenue after discounts, refunds, and allowances.
Mixing costs from one period with units sold from another period.
Treating non-recurring gains as recurring other operating income.
Comparing EBITDA margin calculated on revenue with a margin calculated on revenue plus other operating income.
Allocating all fixed overhead equally when products or services consume resources very differently.

Frequently Asked Questions
What is the formula for EBITDA per unit?
EBITDA per unit equals revenue per unit plus recurring other operating income per unit, minus cost of goods sold per unit and operating expenses per unit.
How do you calculate total EBITDA from EBITDA per unit?
When each unit has the same per-unit EBITDA, multiply EBITDA per unit by units sold. The calculator also reaches the result by using total revenue, total costs, and total other operating income.
Should depreciation and amortization be included in EBITDA per unit?
No. EBITDA is measured before depreciation and amortization, so those amounts should be excluded from the entered cost figures.
Why is EBITDA margin based on revenue rather than total income?
The calculator defines EBITDA margin as EBITDA per unit divided by revenue per unit. This shows operating earnings relative to sales revenue; other operating income is included in EBITDA but not in the denominator.
Can EBITDA per unit be negative?
Yes. A negative result means the entered direct costs and operating expenses exceed revenue plus other operating income for each unit.
