How to Calculate Goodwill in an Acquisition

How to calculate goodwill comes down to a single subtraction: take the consideration paid for a business and deduct the fair value of the identifiable assets and liabilities acquired. The remainder is goodwill, the amount paid above the value of everything that can be measured separately.

This is goodwill as a balance sheet item arising from an acquisition, not goodwill in the sense of general benevolence. It exists only after a transaction: internally generated goodwill is never recognised, however strong the brand or the customer base.

For a controller the number matters far beyond the deal. It drives the carrying amount of intangible assets, the annual charge in the income statement and the equity ratio the bank tests its covenant against. Allocate too little of the price to identifiable assets and goodwill is overstated for years, on the wrong line, with no deferred tax recognised beside it.

What is goodwill?

Goodwill is the difference between the price paid for a business and the fair value of its identifiable net assets. It is the price of what cannot be measured on its own: an experienced team, a customer base with low churn, an established process, a position in the market.

Only acquired goodwill qualifies as an asset. That is why a group growing organically carries a smaller balance sheet than a group that bought the same revenue, even where the underlying businesses are identical.

How to calculate goodwill: the formula

Goodwill = consideration transferred − fair value of the identifiable assets and liabilities acquired

Under IFRS 3 the comparison base is wider: add any non-controlling interest in the acquiree and the fair value of a previously held equity interest to the consideration before deducting the identifiable net assets.

1. Establish the consideration: cash and shares transferred, plus the fair value of any contingent consideration such as an earn-out.
2. Identify every asset acquired, including those absent from the seller's books: brands, customer contracts, an order book, a patent.
3. Measure those assets at fair value rather than carrying amount. A building bought in 1998 is rarely on the books at its market value.
4. Do the same for the liabilities, including obligations not yet recognised: a pending claim, a pension deficit, an onerous contract. Recognise the deferred tax on the remeasurements.
5. Deduct the net result of steps 2 to 4 from the consideration. What remains is goodwill. Every euro allocated to an identifiable asset is a euro less of goodwill.

Worked example: how to calculate goodwill on an acquisition

A group acquires all shares in a service business for € 3,200,000. Equity on the seller's books is € 1,800,000. The allocation shows the building is worth € 250,000 more than its carrying amount, and identifies a customer base and an onerous lease that appear nowhere in the accounts.

Item	Amount
Equity per the seller's books	€ 1,800,000
Remeasurement of the building	+ € 250,000
Customer base (identifiable)	+ € 400,000
Onerous lease	− € 90,000
Deferred tax on the remeasurements (25%)	− € 140,000
Fair value of identifiable assets and liabilities	€ 2,220,000
Consideration transferred	€ 3,200,000

3,200,000 − 2,220,000 = € 980,000 of goodwill. Skip the allocation and the answer would have been € 1,400,000, almost half again as much. The € 420,000 difference does not disappear: it now sits on the building and the customer base, each with its own useful life, with the deferred tax liability recognised alongside.

Is goodwill a fixed asset, and where does it sit?

Goodwill is a non-current intangible asset, presented above tangible and financial fixed assets. In the acquirer's separate accounts the picture differs: a share purchase first lands entirely in the investment in the subsidiary. Only in the consolidated balance sheet does that investment break down into the subsidiary's assets and liabilities plus goodwill. The same acquisition therefore appears in two places; see the article on preparing financial statements for the presentation.

Impairment under IFRS versus amortisation under Dutch GAAP

Under IFRS, goodwill is not amortised. IAS 36 requires an impairment test at least annually, at the level of the cash-generating unit to which goodwill has been allocated, and additionally whenever there is an indication of impairment in between. An impairment loss on goodwill is never reversed.

Under Dutch GAAP (Title 9 of Book 2 of the Civil Code), acquired goodwill is amortised over its expected useful life. Where that life cannot be estimated reliably, article 2:386(3) caps amortisation at ten years, which in practice has made ten years the default and anything longer the exception to be justified in the notes. Dutch tax law is stricter still: at most 10 per cent of cost per year.

A Dutch group therefore carries a fixed charge for ten years, among amortisation of intangible assets in the profit and loss statement, while an IFRS group carries nothing at all until a single year brings a write-down of tens of per cent. Reporting under both frameworks, fix the useful life and the cash-generating unit before the first period is closed.

Negative goodwill

If the consideration falls below the fair value of the net assets acquired, the result is negative. Reassess the allocation first: that arises from a forgotten liability far more often than from a bargain. If it survives the reassessment, IFRS 3 takes the difference straight to profit or loss as a bargain purchase gain, while Dutch GAAP presents it as a separate negative item within intangible assets, released as the expected losses occur.

Keeping goodwill reconciled in the consolidation

Once the acquired entity sits inside the consolidation scope, goodwill returns every period. The investment in the parent's books is eliminated against the subsidiary's equity, and the difference between the two is exactly goodwill plus the non-controlling interest. Those three figures have to reconcile every month: see non-controlling interest for the other half of that calculation, and eliminating intercompany transactions for the balances that sit outside it.

In Smartbooks you group the investments in group companies into a subfolder with the Group Companies behaviour, and the equity accounts into a subfolder set to Equity. The system adds a calculated Group Equity Difference line that exposes the moment those two stop matching, typically because group equity moves monthly while the investment is updated once a year. Goodwill itself and its amortisation are kept in a manual entity: a company without a link to an accounting system, intended for adjustment entries.

Pitfalls

• Working from carrying amounts. Every hidden reserve and every unrecognised obligation then ends up inside goodwill, measured over too long a life and with no deferred tax beside it.
• Leaving the earn-out outside the consideration. Contingent consideration belongs in the price at fair value, and a later remeasurement hits either goodwill or profit depending on the framework.
• Counting goodwill twice. Inside the carrying amount of the investment and again as a separate line in the consolidation. One place only, and the elimination should prove it.
• Allocating goodwill to no cash-generating unit. An unallocated balance cannot be tested under IAS 36, which means the annual test is not actually being performed.
• Recognising internally generated goodwill. Not permitted, even with a valuation report supporting the brand.

Frequently asked questions about how to calculate goodwill

How to calculate goodwill in an acquisition?

Deduct the fair value of the identifiable assets and liabilities acquired from the consideration transferred. Measure every acquired item at fair value first, including assets and obligations that never appeared in the seller's books; whatever remains is goodwill.

Is goodwill amortised?

Under IFRS, no: it is tested for impairment at least annually under IAS 36. Under Dutch GAAP it is amortised over its expected useful life, capped at ten years where that life cannot be estimated reliably.

What is negative goodwill?

Consideration below the fair value of the identifiable net assets acquired. Reassess the measurement first; if the difference stands, IFRS 3 recognises it immediately in profit or loss as a bargain purchase gain.

Does goodwill include the non-controlling interest?

Under the full goodwill method it does: the non-controlling interest is measured at fair value and added to the consideration before the net assets are deducted. Under the proportionate method only the parent's share of goodwill is recognised.

From one-off calculation to a standing balance

Knowing how to calculate goodwill is the straightforward part; keeping it reconciled for ten years is not. Fix the allocation, the useful life and its justification at the acquisition date, then let the amortisation and the elimination run every period instead of resurfacing at year-end. The full sequence is set out in the article on mastering financial consolidation, and how it is configured in a system on the page about consolidation software.
