What Adjustments Are Usually Made to EBITDA and Why?

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is a widely used financial metric that provides a clearer picture of a company’s operating performance. Since it already strips out interest, taxes, and non-cash depreciation and amortization, you might assume it gives you a clean view of the business. But EBITDA still includes every operating expense on your P&L — and that’s where distortions hide.

Owner salaries that don’t reflect market rate. Personal expenses coded as business costs. One-time charges that won’t recur under new ownership. These all sit inside operating expenses and inflate or deflate EBITDA in ways that misrepresent the true run-rate earnings of the business.

Adjusted EBITDA normalizes for these distortions so buyers, sellers, and investors are looking at the same number: what this business would earn under standard management with recurring operations only. This article breaks down the adjustments that actually matter — with specific examples from home services where these normalizations routinely add six or seven figures to enterprise value.

What Adjusted EBITDA Actually Means

Standard EBITDA already removes interest, taxes, depreciation, and amortization from the picture. Adjusted EBITDA goes further by normalizing the remaining operating expenses to reflect what a business would look like under a new owner running it at arm’s length. The adjustments fall into a few categories: compensation normalization, personal expense add-backs, non-recurring operating costs, and related-party transaction corrections. Every adjustment must be to an item that actually flows through operating income — if something is already below the EBITDA line, it’s not an EBITDA adjustment.

The Core EBITDA Adjustments

1. Owner Compensation Normalization

This is typically the single largest EBITDA adjustment in home services transactions. Owner compensation sits in SG&A (or sometimes COGS if the owner runs jobs), so it directly impacts EBITDA. The goal is to replace what the owner actually takes with what a hired general manager would cost. If an HVAC company owner pays themselves $350,000 in W-2 wages and the market rate for a competent GM at that company size is $200,000, the $150,000 difference gets added back. At a 6x multiple, that one normalization adds $900,000 to enterprise value.

2. Family Member Compensation Adjustments

Related to owner comp but tracked separately. Spouses, children, and relatives on payroll are extremely common in home services. The adjustment normalizes their pay to market rate for the role they actually perform — or eliminates the cost entirely if the role wouldn’t exist under professional management. A spouse earning $85,000 as an office manager when market rate is $55,000 creates a $30,000 add-back. A nephew on payroll who doesn’t show up creates a full-salary add-back.

3. Personal Expenses Run Through the Business

This is where small and mid-size home services companies consistently have material add-backs. These are real operating expenses on the P&L that benefit the owner personally rather than the business. Common examples include personal vehicles (lease payments, fuel, insurance — typically $15,000-$40,000/year), cell phone plans for family members, country club or gym memberships, personal travel coded as business trips, meals and entertainment beyond normal business use, owner health insurance premiums above what a standard employee plan would cost, and charitable donations made through the company. Every one of these sits in operating expenses and reduces reported EBITDA. Adding them back is legitimate because a new owner wouldn’t incur them.

4. Non-Recurring Operating Expenses

One-time costs that hit operating expenses but won’t repeat under normal operations. In home services, common examples include legal fees from a specific lawsuit, costs from a warehouse or office relocation, expenses from a failed acquisition or partnership, natural disaster cleanup not covered by insurance, and one-time technology migration costs (like switching from paper to ServiceTitan). The key test: would this cost recur in a typical year? If you had one unusual legal dispute, that’s non-recurring. If you have legal expenses every year from different disputes, a buyer will argue litigation is a normal cost of doing business and reject the add-back.

5. Above- or Below-Market Related Party Transactions

Many home services owners own their shop, warehouse, or yard in a separate LLC and charge the operating company rent. That rent expense is in operating costs and directly affects EBITDA. If the owner charges $8,000/month but market rate for comparable space is $5,000, the $36,000 annual difference gets added back. The reverse also happens — some owners charge below-market rent, which inflates EBITDA. Buyers will normalize to market rate in either direction. The same logic applies to any related-party transactions: subcontracting work to a company the owner also owns, purchasing materials through a related entity at non-market prices, or leasing equipment from a family member’s business.

6. Revenue and Expense Normalization

Some items aren’t add-backs in the traditional sense — they’re corrections to get EBITDA to reflect sustainable run-rate operations. If an owner slashed marketing spend from 12% of revenue to 5% before a sale (inflating short-term EBITDA while cannibalizing lead flow), a buyer will adjust EBITDA downward to reflect what marketing actually needs to be. Similarly, if a company received ERTC credits that were recorded as a reduction to payroll expense rather than as other income, those need to be normalized out since they’re a one-time government program, not recurring savings. Deferred maintenance — skipping fleet replacements or delaying facility repairs to boost near-term profitability — is another area where sophisticated buyers, especially private equity firms, will adjust EBITDA to reflect what true maintenance spend should be.

EBITDA Adjustments Specific to Home Services

Home services businesses — HVAC, plumbing, electrical, and roofing — have a predictable set of adjustments that come up in nearly every acquisition. If you’re thinking about selling your home services business, here’s what buyers will look for.

Owner vehicles. Most home services owners run personal trucks or SUVs through the business. A buyer adds back the personal-use portion — typically $15,000-$40,000/year in combined lease, insurance, fuel, and maintenance per vehicle. Two personal vehicles through the company and you’re looking at a meaningful add-back.

Owner compensation structures. In HVAC and plumbing, owner comp varies wildly. Some pay $150,000 salary plus $200,000 in distributions. Others take $400,000 in W-2 wages. Buyers normalize to what a hired GM or president would cost — typically $150,000-$250,000 depending on company size and market. Everything above that, across all compensation forms, gets added back.

One-time equipment purchases vs. maintenance capex. A $180,000 crane truck or $90,000 fleet vehicle purchased in the trailing twelve months may get added back as non-recurring — but only if it’s truly one-time. If you replace trucks on a regular cycle, that’s maintenance capex and stays in the numbers. This distinction can swing EBITDA by six figures, so have your fleet replacement schedule documented.

Marketing spend manipulation. Cutting marketing before a sale to inflate EBITDA is one of the most common — and most transparent — games sellers play. Buyers look at cost-per-lead trends, lead volume, and revenue trajectory. If leads are declining while EBITDA looks great, they’ll adjust downward to normalized marketing spend.

Software implementation costs. Ongoing ServiceTitan, Housecall Pro, or FieldEdge subscriptions are legitimate operating expenses and stay in EBITDA. But one-time setup, training, data migration, and integration costs from a recent platform switch can be added back as non-recurring.

Facility rent normalization. If your operating company pays rent to your real estate LLC, buyers adjust to market rate. This also drives the decision about whether to include real estate in the deal or structure a separate lease — a choice that significantly impacts both purchase price and the owner’s post-sale income.

How EBITDA Adjustments Affect Your Valuation

The math is straightforward but the stakes are enormous. Home services companies typically trade at 4x-8x adjusted EBITDA, with the multiple depending on size, growth trajectory, customer concentration, recurring revenue mix, and operational maturity. Every $100,000 in legitimate EBITDA adjustments adds $400,000 to $800,000 in enterprise value.

Here’s an example from a $12M revenue HVAC company. Their reported EBITDA was $1.1M. After normalizing operating expenses, adjusted EBITDA came to $1.75M:

• Owner excess compensation (above GM market rate): +$175,000
• Spouse above-market salary (office manager role): +$30,000
• Personal vehicles through business (2 vehicles): +$48,000
• Owner cell phones, meals, travel: +$18,000
• Country club membership: +$15,000
• One-time warehouse relocation costs: +$95,000
• Non-recurring legal fees (subcontractor dispute): +$42,000
• ServiceTitan migration (one-time setup/training): +$35,000
• Above-market rent to owner’s real estate LLC: +$36,000
• Charitable donations through company: +$18,000
• ERTC credits recorded in payroll expense (non-recurring): -$62,000

Note that last line — adjustments go both ways. The ERTC credits reduced payroll expense and inflated EBITDA in the period they were recorded. Since they won’t recur, a buyer normalizes them out, which actually reduces adjusted EBITDA. Honest, bidirectional adjustments build credibility with buyers.

At a 6x multiple, the difference between $1.1M reported and $1.75M adjusted EBITDA is $3.9 million in purchase price. For a comprehensive look at how buyers calculate your company’s valuation, see our guide to home services valuation multiples.

Making Your Adjustments Defensible

Not every add-back survives buyer scrutiny. During due diligence, buyers and their Quality of Earnings (QoE) firms challenge every adjustment. Here’s what separates defensible adjustments from wishful thinking.

Documentation is everything. Every adjustment needs a paper trail. Personal vehicle add-backs need mileage logs or a clear split between business and personal plates. Compensation adjustments need market salary data from recruiting firms or industry surveys. One-time expenses need invoices with dates and descriptions that clearly show the non-recurring nature.

Consistency matters. If you claim an equipment purchase is one-time but your books show similar purchases in three of the last five years, the buyer will reclassify it as maintenance capex. Review at least three to five years of financials to make sure your adjustment narrative holds up over time.

Aggressive adjustments backfire. Buyers expect reasonable adjustments. When an owner presents a schedule claiming $500,000 in add-backs on $800,000 of reported EBITDA, it raises red flags. Quality buyers know what typical adjustments look like for a company of your size and trade. Overreaching erodes trust and can cause buyers to discount legitimate adjustments too.

Prepare 12-18 months before going to market. The worst time to figure out your EBITDA adjustments is during a live transaction. Identify and document adjustments early. Stop running personal expenses through the business. Build clean trailing-twelve-month financials. For a step-by-step approach, see our guide on pre-exit value optimization.

Understanding how adjustments interact with purchase agreement terms is equally important. Working capital pegs, earn-out calculations, and indemnification thresholds are all derived from the adjusted EBITDA baseline. Getting the adjustments wrong doesn’t just affect the headline price — it ripples through every financial term in the deal.

Getting these adjustments right — and having them documented and defensible before you go to market — is one of the highest-ROI things you can do before selling. A fractional CFO who understands home services can typically identify $100,000-$500,000 in legitimate EBITDA adjustments that owners miss or can’t defend. At a 5x-8x multiple, that’s $500,000 to $4 million in additional enterprise value.

Frequently Asked Questions

What is the difference between EBITDA and adjusted EBITDA?

EBITDA removes interest, taxes, depreciation, and amortization from the equation but still includes all operating expenses — including owner-specific costs, one-time charges, and personal expenses run through the business. Adjusted EBITDA normalizes those remaining operating expenses to reflect what the business would earn under standard management. For home services companies, adjusted EBITDA is typically 15-40% higher than reported EBITDA once legitimate normalizations are applied.

What are the most common EBITDA add-backs for home services companies?

The biggest add-backs are owner excess compensation above GM market rate, family member salary normalization, personal vehicles and expenses coded as business costs, one-time legal or relocation costs, and above-market rent paid to an owner’s related real estate entity. For a typical $8M-$15M HVAC or plumbing company, these adjustments collectively range from $200,000 to $750,000.

Can aggressive EBITDA adjustments hurt my sale price?

Yes. Buyers and their Quality of Earnings firms scrutinize every adjustment. Overstating add-backs erodes trust, causes buyers to discount legitimate adjustments, and can lead to price reductions or deal termination during due diligence. The best approach is to present conservative, well-documented adjustments that can withstand third-party verification.

How far in advance should I prepare EBITDA adjustments before selling?

Ideally 12-18 months before going to market. This gives you time to stop running personal expenses through the business, build clean trailing-twelve-month financials, and document every adjustment with supporting evidence. A solid understanding of your P&L is the starting point for identifying which expenses are truly adjustable.
