How Do You Calculate Goodwill?
I'll walk you through the complete process of calculating goodwill in M&A deals. No accounting degree required—just clear explanations and real-world examples.
The Quick Answer
Goodwill = Purchase Price − Net Assets
Where Net Assets = Fair Value of Assets − Fair Value of Liabilities
That's it! Goodwill is simply what you paid minus what you got. The difference represents intangible value like brand, customer relationships, and synergies.
How to Calculate Goodwill in 3 Simple Steps
I've broken down the goodwill calculation process into three manageable steps. Here's how it works in practice.
Step 1: Determine the Purchase Price
Identify the total amount paid for the acquisition. This includes cash, stock, debt assumed, and any other consideration transferred to the seller.
Step 2: Calculate Net Assets
Determine the fair value of all identifiable assets and liabilities. Net Assets = Assets − Liabilities. This represents what you're actually buying.
Step 3: Calculate Goodwill
Subtract Net Assets from the Purchase Price. The result is goodwill—the premium paid for intangible value that can't be separately identified.

Calculate Goodwill NowWhy I Wrote This Guide
When I first learned about goodwill calculation, I found most resources confusing. They either overcomplicated things with accounting jargon or oversimplified to the point of being useless.
I created this guide to fill that gap. Whether you're a student learning M&A accounting, a business owner preparing to sell, or an investment professional analyzing deals, I'll explain goodwill calculation clearly and practically.
Understanding the Goodwill Formula
Let me break down the goodwill formula in detail:
Goodwill = Purchase Price − (Assets − Liabilities)
Purchase Price: The total consideration paid. This could be cash, stock, debt assumption, earn-outs, or any combination thereof. It's what the buyer actually parts with.
Fair Value of Assets: The market value of everything you're acquiring—tangible assets like cash, inventory, equipment, and property, plus identifiable intangible assets like patents, trademarks, and customer lists.
Fair Value of Liabilities: The market value of all debts and obligations you're assuming—loans, accounts payable, warranties, legal contingencies, and any other liabilities.
Real-World Goodwill Calculation Example
Let me walk you through a detailed example. Imagine TechCorp acquires SoftwareInc for $50 million.
The Deal Structure
Purchase Price: $50 million (comprising $40M cash and $10M in TechCorp stock)
What SoftwareInc Owns (Fair Values)
- • Cash: $5 million
- • Equipment & Property: $10 million
- • Software Code (identifiable intangible): $8 million
- • Customer Contracts (identifiable intangible): $7 million
- • Patents (identifiable intangible): $5 million
- • Total Assets: $35 million
What SoftwareInc Owes (Fair Values)
- • Bank Loan: $8 million
- • Accounts Payable: $4 million
- • Total Liabilities: $12 million
Step 1: Calculate Net Assets
Net Assets = $35M − $12M = $23 million
Step 2: Calculate Goodwill
Goodwill = $50M − $23M = $27 million
💡 TechCorp paid $50M for $23M of net identifiable assets. The $27M difference represents goodwill—brand value, customer relationships, synergies, and everything else that makes SoftwareInc valuable beyond its balance sheet.
What Each Component Really Means
Let me dive deeper into each component of the goodwill calculation, because understanding the nuances is crucial for getting it right.
Purchase Price Considerations
The purchase price isn't always just cash. It can include:
- Cash payments at closing
- Stock or equity issued to the seller
- Debt assumed from the target company
- Earn-out provisions (contingent payments based on future performance)
- Non-compete agreements paid to key executives
- Consulting arrangements with the seller
Pro Tip: Under ASC 805, you need to value the earn-outs at fair value at the acquisition date, even though payment is uncertain. This affects your goodwill calculation.
Identifiable Net Assets
This is where most people make mistakes. You need to identify and value EVERY asset and liability:
- Tangible assets: Cash, accounts receivable, inventory, equipment, property, vehicles
- Identifiable intangible assets: Patents, trademarks, customer lists, software, non-compete agreements, domain names
- Liabilities: Accounts payable, loans, warranties, legal contingencies, deferred revenue, pension obligations
Key Point: If you can separate an asset from the business and sell it, it's identifiable. If you can't, it gets bundled into goodwill.
Alternative Goodwill Calculation Methods
While the purchase price allocation method I described is the standard for M&A accounting, there are other ways to think about goodwill for business valuation purposes. Let me explain them.
1. Average Profit Method
This method calculates goodwill based on excess earnings:
Goodwill = Average Profits × Number of Years
Or alternatively: Goodwill = (Average Profits − Normal Return) × Years
Example: If a business earns $200K/year in profit (above industry average) and you multiply by 5 years, goodwill = $1M. This is more common in small business valuations than corporate M&A.
2. Capitalization of Earnings Method
This method calculates goodwill based on capitalized excess earnings:
Goodwill = (Average Profits − Normal Return on Assets) ÷ Capitalization Rate
Example: If excess earnings are $100K and the capitalization rate is 20%, goodwill = $500K. This treats goodwill like a perpetuity.
3. Replacement Cost Method
This method asks: "How much would it cost to recreate this business from scratch?"
Goodwill = Cost to Recreate − Net Asset Value
Example: If it would cost $10M to build the brand, customer base, and systems from scratch, and net assets are $3M, goodwill = $7M. Useful for tech companies with strong platforms.
⚠️ Important Note: For financial reporting under ASC 805 (US GAAP) and IFRS 3 (International), you MUST use the purchase price allocation method (Purchase Price − Net Assets). The alternative methods are for business valuation and negotiation purposes, not accounting.
Negative Goodwill: When It Happens & What It Means
What if the calculation results in negative goodwill? This is called a bargain purchase, and it's rare but real.
Understanding Bargain Purchases
Negative goodwill means you paid less than the fair value of net identifiable assets. This can happen in:
- Distressed sales: The seller is desperate and willing to accept below-market value
- Forced liquidations: Bankruptcy sales, divorce settlements, estate sales
- Fire sales: Quick exits due to health issues, retirement urgency, or other pressures
- Strategic buyers: Sellers who value a quick, certain closing over maximum price
- Miscalculated valuations: Sometimes the buyer just gets an incredible deal
Accounting Treatment: Under ASC 805 and IFRS 3, negative goodwill is recognized as a gain in the income statement at the acquisition date. It's like finding money on the ground—you record an immediate gain.
However, before recognizing a gain, you must reassess all assets and liabilities to make sure you didn't miss anything. The accounting standards assume bargain purchases are rare, so they require extra scrutiny.
Bargain Purchase Example
Imagine you acquire a business for $15 million. The fair value of assets is $30 million, and liabilities are $10 million.
Net Assets = $30M − $10M = $20M
Goodwill = $15M − $20M = −$5M (Negative Goodwill)
You recognize a $5M gain on your income statement. This is rare but legitimate—distressed sellers do exist.
Common Goodwill Calculation Mistakes to Avoid
In my experience, these are the mistakes I see people make most often when calculating goodwill:
❌ Using Book Value Instead of Fair Value
Assets and liabilities should be recorded at fair value, not book value. Book value is historical cost minus depreciation. Fair value is what you could sell it for today. These can be dramatically different, especially for long-held assets.
❌ Forgetting Identifiable Intangible Assets
Customer lists, software, patents, trademarks, non-compete agreements—these are all identifiable intangible assets that should be valued separately, not lumped into goodwill. Missing these inflates goodwill and can cause problems later.
❌ Ignoring Contingent Liabilities
Lawsuits, warranties, environmental obligations—these need to be valued and included in liabilities, even if they're uncertain. Underestimating liabilities inflates net assets and understates goodwill.
❌ Mishandling Earn-Outs
Earn-outs should be valued at fair value at acquisition date and included in the purchase price. Don't wait until they're paid to recognize them. This affects your goodwill calculation from day one.
❌ Double-Counting Assets
Make sure you're not counting the same asset twice. For example, if you value customer contracts as an identifiable intangible, don't also include that value in goodwill. Each asset gets counted once.
Goodwill Impairment Testing Explained
After goodwill is recorded, it's not set in stone. Under current accounting rules, goodwill must be tested for impairment at least annually, or more frequently if there are indicators of decline.
How Impairment Testing Works
Here's the simplified process:
- Assign goodwill to reporting units: Goodwill is allocated to the business units that benefited from the acquisition. You can't test goodwill at the corporate level—it must be tied to operating units.
- Step 1 - Fair Value Test: Compare the fair value of the reporting unit to its carrying value (including goodwill). If fair value ≥ carrying value, no impairment. Skip to Step 2.
- Step 2 - Implied Goodwill Test: If fair value < carrying value, calculate implied goodwill (pretend you're acquiring the unit today) and compare to recorded goodwill. The difference is your impairment loss.
- Recognize impairment loss: The impairment loss reduces goodwill on the balance sheet and hits the income statement. Goodwill can never go below zero—you can't have negative goodwill after impairment.
Key Point: Impairment is a one-way street. Once goodwill is impaired, it's gone forever. It doesn't recover if the business improves later. This is why buyers are so careful about what they pay.
Impairment Example
Five years after an acquisition, the acquired business unit has:
- Carrying value (including goodwill): $100M
- Fair value: $75M
- Implied goodwill (if acquired today): $15M
- Recorded goodwill on balance sheet: $35M
Impairment Loss = $35M − $15M = $20M
You record a $20M impairment loss and reduce goodwill from $35M to $15M on the balance sheet. This is a painful hit to earnings.

Goodwill in Different Contexts
Goodwill calculation varies depending on the context. Let me explain how it differs across scenarios.
Corporate M&A (ASC 805 / IFRS 3)
For public companies and large private acquisitions, goodwill is calculated using formal purchase price allocation. Independent valuation experts are often hired. The result is audited and appears in financial statements. This is the most rigorous approach.
Small Business Acquisitions
For main street businesses (restaurants, retail, services), goodwill is often calculated more informally. Buyers might use the "excess earnings" method or simple multiples of SDE/EBITDA. The calculation is less about accounting compliance and more about negotiation.
Startup Acquisitions
Startup deals often have significant goodwill because buyers pay for team, technology, and market potential rather than hard assets. Purchase price allocation can be tricky when there's little revenue and no profits. Much of the value ends up in goodwill or "developed technology" intangible assets.
Asset Purchases vs. Stock Purchases
In an asset purchase, you buy specific assets and assume specific liabilities. Goodwill is calculated only on what you actually acquire. In a stock purchase, you buy the entire entity, including all assets and liabilities, known and unknown. Goodwill calculation differs between these structures.
Frequently Asked Questions
What is the simplest way to calculate goodwill?
The simplest goodwill calculation is: Goodwill = Purchase Price − (Fair Value of Assets − Fair Value of Liabilities). First, determine what you paid. Then, calculate the fair value of all identifiable assets and liabilities. Subtract liabilities from assets to get net assets. Finally, subtract net assets from the purchase price. The result is goodwill.
Can you calculate goodwill with an example?
Sure! If Company A acquires Company B for $50 million, and Company B has $40 million in assets (fair value) and $15 million in liabilities (fair value), then Net Assets = $40M − $15M = $25M. Goodwill = $50M (Purchase Price) − $25M (Net Assets) = $25 million. This $25M represents the premium paid for intangible value.
How do you calculate goodwill on a balance sheet?
Goodwill appears as a separate line item under non-current assets on the balance sheet. It's recorded at the acquisition date and is tested for impairment annually, not amortized. To calculate it, use the purchase price allocation formula: Purchase Price − (Assets − Liabilities) = Goodwill. This amount is then reported on the acquiring company's balance sheet.
What is the formula for calculating goodwill?
The standard formula for goodwill calculation is: Goodwill = Purchase Price − Fair Value of Net Identifiable Assets. Alternatively: Goodwill = Purchase Price − (Fair Value of Assets − Fair Value of Liabilities). This formula applies under ASC 805 (US GAAP) and IFRS 3 (International Financial Reporting Standards).
How do you calculate average profit goodwill?
The average profit method calculates goodwill as: Goodwill = Average Profits × Number of Years. For example, if a business has average profits of $200,000 and you use a 5-year multiple, goodwill = $1,000,000. Alternatively, some versions use: Goodwill = (Average Profits − Normal Return on Assets) × Years. This method is more common in small business valuation than corporate accounting.
How do you calculate negative goodwill?
Negative goodwill (also called a bargain purchase) occurs when Purchase Price < Net Assets. For example, if you pay $15 million for a business with $30 million in assets and $10 million in liabilities, Net Assets = $20 million. Goodwill = $15M − $20M = −$5 million. Under ASC 805 and IFRS 3, negative goodwill is recognized as a gain in the income statement at acquisition.
Do you calculate goodwill before or after deducting debt?
Goodwill is calculated AFTER deducting debt. The formula is: Goodwill = Purchase Price − (Assets − Liabilities). Liabilities include all debts. So you subtract liabilities (debt) from assets to get net assets, then subtract net assets from the purchase price. Debt reduces net assets, which increases goodwill for a given purchase price.
How do you calculate goodwill impairment?
Goodwill impairment testing involves two steps. Step 1: Compare the fair value of the reporting unit to its carrying value (including goodwill). If fair value ≥ carrying value, no impairment. If fair value < carrying value, proceed to Step 2. Step 2: Calculate implied goodwill as if acquiring the unit today, then compare implied goodwill to recorded goodwill. If recorded goodwill exceeds implied goodwill, the difference is the impairment loss.
How is goodwill different from other intangible assets?
The key difference is separability. Identifiable intangible assets (patents, trademarks, customer lists) can be separated from the business and sold independently. Goodwill cannot be separated—it's the residual value of everything that can't be specifically identified. When calculating goodwill, you first value all identifiable intangibles separately, then whatever is left becomes goodwill.
Why do buyers pay goodwill?
Buyers pay goodwill because they're acquiring more than just tangible assets. Goodwill represents: (1) Brand reputation and recognition, (2) Customer relationships and recurring revenue, (3) Synergies from combining businesses, (4) Assembled workforce and expertise, (5) Market position and competitive advantages, (6) Technology and processes. These have real economic value even if they can't be separately measured.
How do you calculate goodwill for a small business?
For small businesses, goodwill is often calculated using the excess earnings method: Goodwill = (Average Profits − Reasonable Return on Assets) × Multiplier. Alternatively, buyers simply calculate: Total Price − Fair Value of Tangible Assets = Goodwill. This is less formal than corporate M&A but follows the same principle—paying for intangible value beyond hard assets.
What happens to goodwill after acquisition?
After acquisition, goodwill is recorded on the balance sheet and is tested for impairment annually (under ASC 805/IFRS 3). It is not amortized. If the fair value of the acquired business falls below its carrying value, an impairment loss is recognized, reducing goodwill. Goodwill stays on the balance sheet indefinitely unless impaired. Unlike depreciation, goodwill doesn't create a recurring expense.
