1. The Australian Business Valuation Framework (2026–27)
Business valuation in Australia follows established corporate finance methodologies endorsed by the Australian Institute of Business Brokers (AIBB).
Whether preparing for a business sale, partner buyout, commercial loan application, or ATO tax reorganization, establishing a credible valuation rests on normalized earnings and objective industry risk multiples.
2. SDE Earnings Level & Business Valuation Benchmarks
| Annual Profit / SDE | EBITDA Multiple | Tangible Asset Value | Estimated Valuation | Method Used |
|---|---|---|---|---|
| $150,000 SDE | 2.0x Multiple | $30,000 Assets | $330,000 ($300k Goodwill + $30k Equipment) | SDE Multiple + Assets |
| $350,000 SDE | 3.0x Multiple | $75,000 Assets | $1,125,000 Total Valuation | EBITDA Multiple |
| $750,000 EBITDA | 3.8x Multiple | $200,000 Assets | $3,050,000 Total Valuation | Capitalization of Earnings |
| $1,500,000 EBITDA | 4.5x Multiple | $500,000 Assets | $7,250,000 Enterprise Value | EBITDA Multiple (Mid-Market) |
3. The Mathematics of Earnings Multiples & Goodwill
Total Enterprise Business Valuation (Val_total) for normalized annual earnings (SDE), earnings multiple (M), and tangible net assets (NTA) is:
Example Calculation ($350,000 SDE @ 3.0x Multiple + $75,000 NTA):
- Business Goodwill: $350,000 × 3.0 = $1,050,000.00.
- Plant & Equipment Assets: $75,000.00.
- Total Estimated Enterprise Valuation = $1,050,000 + $75,000 = $1,125,000.00 (+ SAV Stock).

Frequently Asked Questions (FAQ)
What is the most common business valuation method for Australian small businesses?
The Earnings Multiple method (using EBITDA or Seller Discretionary Earnings - SDE) is the most widely accepted method for Australian small businesses earning under $5 million. Valuation = Normalized Annual SDE/EBITDA × Industry Multiple (typically 2.0x to 4.5x).
What is the difference between EBITDA and Seller Discretionary Earnings (SDE)?
EBITDA stands for Earnings Before Interest, Tax, Depreciation, and Amortization. SDE starts with net profit and adds back a working owner’s salary, personal expenses, and non-recurring items, measuring total financial benefit generated for a single owner-operator.
What typical EBITDA multiples apply to Australian small-to-medium businesses?
Micro businesses (under $200k SDE) typically fetch 1.5x – 2.5x SDE. Established small businesses ($200k–$1M EBITDA) fetch 2.5x – 4.0x EBITDA. Medium enterprises ($1M–$5M EBITDA) with recurring revenue and strong management teams fetch 4.0x – 6.0x EBITDA.
How does Stock on Hand (SOH) affect total business sale price in Australia?
In Australian business sales, stock is usually sold "plus stock at valuation" (SAV). Total Purchase Price = Agreed Business Valuation (Goodwill + Fixtures) + Wholesale Value of Saleable Stock on Hand.
Can business valuation expenses be claimed as a tax deduction?
Valuation costs incurred for operational purposes or asset restructuring may be deductible. Valuations undertaken solely for selling a business are capital in nature and are added to the cost base for CGT calculations rather than immediately deducted.
