What Purchase Price Allocation Calculator does, with a checked example

After a business acquisition, the buyer must restate the target's balance sheet at fair value and show what portion of the price lands in goodwill. This tool takes the purchase price, the fair values of the tangible assets and identifiable intangibles acquired, and any liabilities assumed, then computes goodwill as the residual. The surprise: goodwill is not what you paid over book equity. Every asset must be entered at appraisal-based fair value, and assumed liabilities reduce the net assets the price is measured against, so both inputs move the residual.

Worked example

A concrete input and expected output from the current implementation.

Input

Purchase price: $12,000,000. Liabilities assumed: $2,000,000. Tangible assets at fair value: $8,000,000. Identifiable intangibles at fair value: $3,000,000 (customer relationships $2,000,000, developed technology $1,000,000).

Expected output

Goodwill: $3,000,000. Allocation: tangible assets $8,000,000, identifiable intangibles $3,000,000, goodwill $3,000,000, total recognized $14,000,000, matching consideration transferred ($12,000,000) plus liabilities assumed ($2,000,000).

Net identifiable assets are $8,000,000 + $3,000,000 minus $2,000,000 = $9,000,000, so goodwill is $12,000,000 minus $9,000,000 = $3,000,000. The recognized total of $14,000,000 equals what was paid plus the liabilities taken on, which is how the allocation must balance.

How the result is produced

1

Residual goodwill computation

Goodwill is the balancing figure: consideration transferred minus the fair value of identifiable net assets (tangible plus intangible assets, minus liabilities assumed). The tool totals the asset subtotals, subtracts the liabilities, and deducts that net amount from the purchase price. Because fair value, not book value, is the measuring stick, a large appraisal step-up shrinks goodwill dollar for dollar, and a negative residual signals a bargain purchase rather than negative goodwill.

2

Intangibles versus goodwill

Identifiable intangibles (customer relationships, developed technology, trade names, backlog, non-compete agreements) must satisfy the contractual-legal or separability criteria in ASC 805 or IFRS 3 to be recognized apart from goodwill, and most are amortized over their useful lives. Goodwill, the remainder after all identifiable items are valued, is generally not amortized and is tested for impairment, so this split largely decides the target's future earnings.

Good uses

  • Booking the acquisition's opening balance sheet after closing and setting up amortization schedules for the intangible assets.
  • Modeling a deal before signing: estimate how much of the price will land in amortizable intangibles versus non-amortizable goodwill, which changes pro forma earnings per share.
  • Reviewing a valuation firm's PPA memo: re-enter its fair values, confirm the residual goodwill moves consistently with the appraisals, and investigate a bargain-purchase result.

Limits and checks

  • The output is only as good as the fair values you enter. The tool does the arithmetic; it does not value customer lists, technology, or trade names. Without a defensible appraisal behind each number, the allocation has no support.
  • Book values are the classic mistake: entering them instead of fair values inflates net assets and shrinks goodwill. Omitting liabilities assumed does the opposite and makes the allocation fail its balance-sheet check.
  • A negative residual is not negative goodwill. Under ASC 805-30-25-2 and IFRS 3.34 it is recorded as a bargain purchase gain, and the fair values should be re-verified first. The result also ignores deferred taxes on fair value step-ups, which a complete PPA must include.

Common questions

Why is my goodwill not just purchase price minus the target's book equity?

Because the allocation never uses book equity. Book equity reflects historical cost, while the price is measured against the fair value of the identifiable net assets acquired. When appraisals value those assets above book, the goodwill residual is correspondingly smaller than price minus equity, and it can even go negative in a bargain purchase.

Can I deduct this goodwill on my tax return?

Not from this tool's output. Tax treatment is separate: goodwill and most other acquired intangibles amortize over 15 years under IRC Section 197, and whether you bought assets or stock changes what is deductible. The tool produces a financial-statement allocation under GAAP or IFRS, not a tax computation, so take the output to a tax advisor.
