EBITDA

What Is EBITDA?

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is one of the most commonly used metrics in business finance to measure a company’s operating profitability.

It answers the question: how much profit does this business generate from its core operations, before financing decisions and accounting treatment cloud the picture?

The EBITDA Formula

EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization

Or equivalently:

EBITDA = Operating Profit (EBIT) + Depreciation + Amortization

Example:

• Revenue: $10M
• Operating costs: $7M
• EBIT (Operating profit): $3M
• Depreciation & Amortization: $500K
• EBITDA: $3.5M
• EBITDA margin: 35%

Why Each Add-Back Matters

Add-back	Why it’s excluded
Interest	Reflects capital structure (debt vs. equity), not operations
Taxes	Vary by jurisdiction and tax strategy
Depreciation	Non-cash charge based on accounting policy
Amortization	Non-cash write-down of intangible assets (patents, goodwill)

By adding these back, EBITDA creates a cleaner picture of core operating performance that allows comparison across companies with different debt levels, tax situations, and asset mixes.

EBITDA in Startup Valuations

Investors and acquirers frequently value businesses using EBITDA multiples:

• SaaS companies: 10–20× EBITDA (at scale and profitability)
• E-commerce: 5–12× EBITDA
• Services businesses: 4–8× EBITDA

The multiple varies by growth rate, industry, and market conditions. High-growth companies often trade at higher multiples even with low EBITDA, because investors value future earnings potential.

EBITDA vs. Other Profitability Metrics

Metric	What it shows	Includes
Gross Profit	Revenue minus direct costs	-
EBITDA	Operating profit before non-cash and financing items	More of the cost structure
EBIT	Operating profit after depreciation	D&A
Net Income	Profit after everything	Interest, taxes, D&A

When EBITDA Matters for Startups

For pre-revenue and early-stage startups, EBITDA is largely irrelevant — investors focus on growth, product-market fit, and revenue momentum. EBITDA becomes meaningful when:

• You’re approaching or at profitability
• You’re raising growth equity or debt financing
• You’re preparing for an acquisition
• You’re benchmarking against public company comps

The EBITDA margin (EBITDA as a percentage of revenue) is often more useful than the absolute number for tracking improvement over time.

Key Takeaway

EBITDA is a useful tool for measuring and comparing operating profitability — but it’s not the same as cash flow or profit. Use it alongside metrics like free cash flow, gross margin, and net income to get the full picture. For SaaS startups specifically, the Rule of 40 (growth rate + EBITDA margin ≥ 40%) is a more relevant and commonly used benchmark than EBITDA in isolation.
