Adjusted EBITDA: Complete Normalization Guide
Learn how to properly adjust EBITDA for business valuation with expert guidance on normalization techniques, acceptable adjustments, and documentation requirements
Calculate Your Adjusted EBITDAWhat is Adjusted EBITDA?
Is your company's standard income statement telling the whole story? For most businesses, it isn't. One-time expenses or unusual events can obscure a company's true earning power. That's where Adjusted EBITDA comes in. It's a crucial metric designed to show a potential buyer the real, sustainable cash flow your business generates.
Adjusted EBITDA (also called Normalized EBITDA) is the base EBITDA calculation with additional adjustments to remove non-recurring, unusual, or non-business expenses to show the true operating performance of a business. Understanding the difference between EBITDA and SDE is crucial before making adjustments.
Common EBITDA Adjustments
Adjusting for documented, one-time costs that are not part of normal operations:
- Legal settlement costs
- Restructuring expenses
- Major equipment repairs
- Acquisition costs
- COVID-related expenses
Normalizing owner compensation to a fair market rate and adding back verified personal expenses paid for by the business:
- Above-market owner salary
- Owner bonuses
- Family member wages
- Excessive benefits
- Owner pension contributions
Personal expenses inappropriately run through the business:
- Personal vehicle expenses
- Personal travel/entertainment
- Family cell phone bills
- Personal insurance premiums
- Non-business meals
Non-cash expenses that reduce reported income:
- Stock-based compensation
- Impairment charges
- Bad debt write-offs
- Asset write-downs
- Goodwill amortization
Adjustments to reflect market conditions or normalize operations:
- Below-market rent
- Above-market rent
- Related party transactions
- Unusual bad debt losses
- Seasonal adjustments
Adjustments for recent business model or operational changes:
- Discontinued operations
- New product launch costs
- System implementation
- Training and startup costs
- Lost customer transitions
A Word of Caution: The Art and Science of Adjustments
Every adjustment, whether adding back an expense or normalizing revenue, must be rigorously documented and defensible. An unsubstantiated adjustment is worthless under scrutiny from the IRS, a buyer's due diligence team, or in court.
A credible valuation hinges on the quality and proof of its adjustments. This means maintaining detailed records, supporting documents, and clear explanations for every normalization made.
5-Step Adjusted EBITDA Process
Calculate Base EBITDA
Start with net income and add back interest, taxes, depreciation, and amortization to establish your base EBITDA figure.
Identify Adjustments
Review financial statements for the past 3-5 years to identify potential adjustments. Look for unusual, non-recurring, or personal items.
Pro Tip: Review each expense category line-by-line and ask "Would a new owner incur this expense in normal operations?"
Validate Each Adjustment
Each adjustment must be reasonable, well-documented, and pass the "would a buyer accept this?" test. Conservative adjustments are more defensible.
✓ Valid Adjustments
- • Documented one-time expenses
- • Personal expenses with receipts
- • Above-market owner compensation
- • Non-business travel
✗ Invalid Adjustments
- • Normal business expenses
- • Required maintenance costs
- • Regular operating expenses
- • Reasonable owner salary
Document Everything
Maintain detailed documentation for every adjustment including supporting documents, explanations, and calculations. This is critical for credibility.
Documentation Requirements:
- Clear description of each adjustment
- Supporting invoices, receipts, contracts
- Calculation methodology
- Justification for normalization
Calculate Final Adjusted EBITDA
Add all validated adjustments to your base EBITDA to arrive at your final adjusted EBITDA figure for valuation purposes.

Adjusted EBITDA Best Practices
1. Over-Adjusting
Adding back legitimate business expenses that a new owner would incur.
2. Poor Documentation
Failing to maintain supporting documentation for adjustments.
3. Inconsistent Treatment
Applying adjustments inconsistently across different time periods.
4. Ignoring Buyer Perspective
Not considering what adjustments buyers will accept.
5. Timing Issues
Making adjustments for expenses that haven't actually been incurred.
1. Be Conservative
When in doubt, don't adjust. Conservative adjustments are more credible. Learn about common valuation mistakes to avoid over-adjusting.
2. Maintain Documentation
Keep detailed records and supporting documents for every adjustment.
3. Use Market Benchmarks
Base compensation adjustments on market data for similar roles.
4. Get Professional Review
Have adjustments reviewed by a valuation professional.
5. Consider Multi-Year Average
Use 3-5 year average adjusted EBITDA for more stable valuations.
Adjusted EBITDA FAQ
How much can I reasonably adjust EBITDA?
There's no hard rule, but adjustments typically range from 10-30% of base EBITDA for most small businesses. Larger adjustments require exceptional documentation and justification. Focus on quality and defensibility over quantity.
Should I adjust for COVID-related impacts?
Yes, but carefully. Add back extraordinary COVID expenses (PPP loan costs, one-time safety equipment) but be cautious about operational changes that may be permanent. Consider both positive and negative COVID impacts for fairness.
Can I adjust for future synergies or improvements?
No. Adjusted EBITDA should reflect historical performance normalized for one-time items, not future potential. Synergies and improvements are considered separately in valuation analysis and may justify premium pricing.
How do I handle owner salary adjustments?
Research market salaries for similar positions in your industry and geography. Adjust to market rate, not to zero. Document your research with salary surveys or job postings. Remember that buyers need to budget for replacement management.
