What is EBITDA?

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) measures operating profitability by excluding non-cash expenses and financing costs. For professional service firms, EBITDA is calculated as Net Income plus Interest plus Taxes plus Depreciation plus Amortization. A consulting firm with $400,000 net income, $15,000 in interest, and $12,000 in depreciation has $427,000 in EBITDA. EBITDA approximates cash generated from operations and is commonly used in business valuations: service firms typically sell for 4-8x EBITDA depending on size, growth rate, and client concentration.

Key characteristics of EBITDA

1. Formula: Net Income + Interest + Taxes + Depreciation + Amortization = EBITDA

2. Alternative calculation: Operating Income + Depreciation + Amortization

3. Non-GAAP metric: Not required in financial statements but widely used in business analysis

4. Valuation multiple: Professional service firms are typically valued at 4-8x EBITDA

5. Cash proxy: Approximates cash generated before debt service and capital expenditures

Why ebitda matters for service firms

EBITDA is the primary metric for business valuation and acquisition pricing. A consulting firm with $600,000 in EBITDA, valued at 6x, is worth approximately $3.6M. EBITDA enables comparison across firms with different capital structures and tax situations: one firm might be debt-free (no interest), another heavily leveraged; EBITDA removes financing differences to show underlying operating performance. Lenders evaluate EBITDA for loan capacity: the debt service coverage ratio compares EBITDA to loan payments. Growing EBITDA from $400,000 to $700,000 increases business value by approximately $1.8M at a 6x multiple. EBITDA is imperfect: it it ignores changes in working capital and capital expenditure requirements.
