Use the result with context

Results are estimates for planning and education. Confirm rates, taxes, fees, and legal requirements with the relevant institution or a qualified professional before making a financial decision.

Formula and method

Subtract identifiable assets at fair value from the purchase price, then add assumed liabilities at fair value. This simplified full-acquisition model estimates the amount above net identifiable assets.

Goodwill estimate = purchase price − asset fair value + liability fair value

Worked example

Enter these known values and leave the other values blank.

Purchase price
100000 USD
Fair value of the asset
90000 USD
Fair value of the liabilities
10000 USD
Goodwill
20000 USD

Assumptions and limitations

  • Use values from a consistent period, scope and currency. The stated formula defines this simplified model; the explanation describes quantities it leaves out.

Common questions

Does a negative amount mean negative goodwill is booked?

A negative result flags a possible bargain purchase for review. Actual accounting treatment requires the applicable acquisition rules and a review of the valuation inputs.
