About the EBITDA Calculator
Two companies can report wildly different net income even with similar underlying operations, simply because one carries more debt or depreciates assets faster. EBITDA strips out those differences to get closer to raw operating performance. Our EBITDA Calculator adds interest, taxes, and depreciation and amortization back onto net income to compute it, plus an optional margin.
How It Works
You enter net income, interest expense, taxes, and depreciation and amortization, and the calculator adds all four together to produce EBITDA. If you also provide revenue, it divides EBITDA by revenue to calculate EBITDA margin as a percentage.
Formula & Methodology
Each add-back removes a specific layer of variation between companies. Interest is added back because it reflects financing choices (how much debt versus equity a company uses), not operating performance. Taxes are added back because tax rates vary by jurisdiction and tax strategy. Depreciation and amortization are added back because they're non-cash accounting allocations of past capital spending, not current cash costs. What remains is meant to approximate operating cash profit before any of those structural or accounting differences, which is why EBITDA is popular for comparing companies that otherwise look quite different on the bottom line.
Examples
Basic calculation
With $200,000 net income, $30,000 interest expense, $60,000 in taxes, and $50,000 depreciation and amortization, EBITDA comes to $340,000.
With margin
If that same company reports $1,200,000 in revenue, its EBITDA margin works out to roughly 28%, showing what share of revenue converts to operating profit before financing and accounting adjustments.
Advantages
- Strips out financing structure, tax jurisdiction, and depreciation policy for cleaner comparisons
- Widely used in valuation multiples like EV/EBITDA, making it easy to benchmark against peers
- Simple to calculate directly from figures already on an income statement
- Adds an EBITDA margin so profitability can be compared as a percentage of revenue too
Common Mistakes
- Treating EBITDA as equivalent to actual cash flow, when it ignores capital expenditures and changes in working capital
- Comparing one company's self-reported "adjusted EBITDA" to another's unadjusted figure without checking what was added back
- Using EBITDA alone to judge a highly leveraged company, since it ignores the real cash cost of servicing that debt
- Forgetting that non-cash D&A still reflects real past spending on equipment or assets that will eventually need replacing
Edge Cases to Watch For
- EBITDA margin only calculates if you enter a revenue figure; otherwise the calculator shows a dash for that field.
- EBITDA ignores capital expenditures entirely, so a capital-intensive business can show strong EBITDA while still spending heavily just to maintain its asset base.
- It's not a measure recognized under GAAP or IFRS, so companies can define and calculate their own "adjusted EBITDA" with additional add-backs, making cross-company comparisons less reliable than they first appear.
- A company with negative net income can still show positive EBITDA if depreciation, interest, and taxes are large enough, which can mask real profitability problems.
Common Use Cases
- Comparing operating performance across companies with different debt loads or tax situations
- Calculating valuation multiples like EV/EBITDA for M&A or investment analysis
- Tracking a company's operating profitability trend over time
- Quick-screening potential investments before deeper due diligence
