EBITDA Multiple Valuation Calculator
EBITDA multiples are the standard valuation shortcut for profitable businesses, especially in private equity and lower-mid-market M&A. They work best when EBITDA is a reasonable proxy for cash flow.
The EBITDA multiple formula
EBITDA — earnings before interest, taxes, depreciation, and amortization — strips out capital structure (interest), tax jurisdiction effects, and non-cash accounting (D&A) to produce a comparable proxy for operating cash flow. Multiplying by a sector multiple converts current operating performance into an enterprise value estimate.
Why net debt matters
Enterprise value covers the whole capital stack — debt and equity. To get the price an equity buyer would pay, subtract net debt (debt minus excess cash) from EV. Two companies with identical EBITDA and identical multiples can have very different equity values if one is leveraged and the other isn't.
Normalizing EBITDA
For private companies and especially owner-operated businesses, reported EBITDA usually understates the cash flow available to a new owner. Common addbacks: owner salary above market, family members on payroll, one-time legal or restructuring expense, discretionary travel, and personal vehicles. Sellers' brokers maximize addbacks; buyers' diligence teams minimize them. The negotiated figure — adjusted EBITDA — is what the multiple gets applied to.
Worked example
A regional services business has $3.2M of trailing EBITDA, $400K in addbacks (owner salary normalization, personal expenses run through the business), and $800K of net debt. Adjusted EBITDA: $3.6M. At a 5.5× multiple typical for the sector, EV = $19.8M. Equity value = $19M. The implied revenue multiple, against $14M of revenue, would be ~1.4× — useful for cross-checking against public comparables.
What EBITDA multiples don't account for
- Capex intensity. A capital-intensive business with $1M of EBITDA but $700K of annual capex has very different free cash flow than a low-capex business with the same EBITDA. EBITDA-CapEx multiples address this; pure EBITDA multiples don't.
- Working capital needs. Growing businesses need to fund receivables and inventory; EBITDA ignores this drag.
- Customer concentration and contract durability. Two businesses with the same EBITDA but very different revenue quality should trade at different multiples, but lazy comp work treats them identically.
- Comparable selection. Sector multiples come from picking comparables; pick them strategically and you can justify almost anything. Independent diligence reframes this often.
