How to Calculate Non-controlling Interest in Consolidation

Updated 11 October 2026 · Fact-checked

Non-controlling interest (NCI) is the share of a subsidiary's net assets and profit that belongs to shareholders other than the parent. Under the proportionate method, NCI in the SOFP is NCI % × the subsidiary's net assets at the reporting date. NCI in profit is NCI % × the subsidiary's profit after tax.

Understand Non-controlling Interest

When a parent owns more than half the voting shares of a subsidiary, it controls the subsidiary. Under IFRS 10 you consolidate 100% of the subsidiary's assets, liabilities, income and expenses. This is true even if the parent owns only 60%.

Because you include 100%, you must show who owns the part the parent does not own. That is the non-controlling interest (NCI). It is the equity of the subsidiary that belongs to outside shareholders. In the consolidated statement of financial position it appears within equity, shown separately from the parent's equity.

IFRS 3 allows two ways to measure NCI at acquisition: fair value, or the proportionate share of the subsidiary's net assets. This guide covers the proportionate share of net assets method. It is the simpler one. NCI at the reporting date is NCI % × the subsidiary's net assets at that date.

NCI also takes a share of profit. In the consolidated statement of profit or loss you add up 100% of the subsidiary's income and expenses. Then you split the profit after tax for the year between the owners of the parent and the NCI. The NCI share is NCI % × the subsidiary's profit after tax. The same split applies to total comprehensive income.

Think of it as a split of the same total. The whole group is shown at 100%. NCI is the slice that belongs to outsiders. The rest belongs to the parent's shareholders.

Key formulas to remember

NCI %
NCI % = 100% − parent's % shareholding
Use the percentage of ordinary shares with voting rights. In FA questions this is usually the share ownership percentage.
NCI in the consolidated SOFP (proportionate method)
NCI = NCI % × subsidiary's net assets at the reporting date
Net assets at the reporting date means share capital + reserves, after any fair value adjustments and unrealised profit adjustments on the subsidiary's side.
Subsidiary's net assets at reporting date
Net assets = share capital + reserves (adjusted for fair value changes and any unrealised profit in the subsidiary's inventory)
Either add up equity or total assets less liabilities. Both give the same figure.
NCI share of profit
NCI in profit = NCI % × subsidiary's profit after tax for the year
If the subsidiary was acquired part-way through the year, use only the post-acquisition profit. Adjust profit first for fair value depreciation or unrealised profit if the subsidiary sold the goods.
Profit attributable to owners of the parent
Group profit after tax − NCI share of profit
Show both figures at the foot of the consolidated statement of profit or loss.

How to solve Non-controlling Interest questions

Use this method for any NCI question. It works for the SOFP and for the statement of profit or loss.

  1. 1Find the parent's holding and work out the NCI percentage: 100% minus the parent's percentage.
  2. 2Decide what is asked: NCI in the SOFP (net assets) or NCI in profit (profit after tax for the year).
  3. 3For the SOFP, write down the subsidiary's net assets at the reporting date: share capital plus reserves, or assets less liabilities.
  4. 4Adjust those net assets for any fair value adjustments still in place and for unrealised profit on goods the subsidiary sold to the parent and which remain in inventory.
  5. 5Multiply the adjusted net assets by the NCI percentage. This is the NCI figure for the SOFP.
  6. 6For profit, take the subsidiary's profit after tax for the year (post-acquisition only if acquired during the year), adjust it for the same items, and multiply by the NCI percentage.
  7. 7Show NCI separately: within equity in the SOFP, and as a deduction from group profit in the statement of profit or loss.
  8. 8Check the answer: parent's share plus NCI share should equal 100% of the subsidiary's net assets or profit.

Quickest way: Percentage times net assets or profit

When to use it: Use this in Section A objective tests when the question gives a simple holding and subsidiary figures and asks for one NCI number.

  1. Write the NCI % first, for example 25% if the parent owns 75%.
  2. Pick the right base: net assets at the reporting date for the SOFP, profit after tax for the year for the income statement.
  3. Scan the question for adjustments: fair value changes, unrealised profit in the subsidiary's books, or acquisition part-way through the year.
  4. Adjust the base, then multiply by the NCI %.
  5. Eliminate options that use the parent's % or net assets at acquisition.

Common mistakes in Non-controlling Interest

  • Using the parent's percentage instead of the NCI percentage.

    The parent's holding is the number given in the question, so students multiply by it by habit.

    Fix: Always write NCI % = 100% − parent % as your first line.

  • Using the subsidiary's net assets at the acquisition date to calculate NCI in the SOFP.

    Students mix up the goodwill working, which uses acquisition-date net assets, with the NCI working.

    Fix: For the SOFP the NCI uses net assets at the reporting date. Acquisition-date net assets belong in the goodwill calculation.

  • Including the full year's subsidiary profit when the subsidiary was bought part-way through the year.

    Students forget that only post-acquisition results are consolidated.

    Fix: Time-apportion the subsidiary's profit and use only the period after acquisition, both for the group figure and for the NCI share.

  • Taking the NCI share of the parent's profit as well.

    Students think NCI owns part of the group as a whole.

    Fix: NCI shares only in the subsidiary's net assets and profit. The parent's own results belong wholly to the parent's shareholders.

  • Forgetting to adjust for unrealised profit or fair value depreciation before applying the NCI %.

    Students calculate NCI from the raw subsidiary figures.

    Fix: Adjust the subsidiary's net assets or profit first. If the subsidiary sold the goods, NCI shares in the unrealised profit adjustment.

  • Showing NCI as a liability.

    It sounds like an amount owed to outsiders.

    Fix: NCI is part of group equity. Show it within equity, separate from the parent's equity.

Worked examples

Example 1

Parent buys 80% of Sub on 1 January. At 31 December Sub has share capital of $100,000 and reserves of $140,000. There are no fair value adjustments or intragroup items. Calculate the NCI in the consolidated statement of financial position at 31 December.

Show the solution
  1. NCI % = 100% − 80% = 20%.
  2. Net assets of Sub at 31 December = $100,000 + $140,000 = $240,000.
  3. No adjustments are needed.
  4. NCI = 20% × $240,000 = $48,000.

Answer: NCI in the consolidated statement of financial position is $48,000.

Example 2

Parent owns 70% of Sub for the whole year. Sub's profit after tax is $90,000. Sub sold goods to Parent during the year and $20,000 of unrealised profit is in Parent's closing inventory. Parent's own profit after tax is $200,000. Calculate the NCI share of profit and the profit attributable to the owners of the parent.

Show the solution
  1. NCI % = 100% − 70% = 30%.
  2. Sub sold the goods, so the unrealised profit adjustment reduces Sub's profit: $90,000 − $20,000 = $70,000.
  3. NCI share of profit = 30% × $70,000 = $21,000.
  4. Group profit after tax = $200,000 + $70,000 = $270,000.
  5. Attributable to owners of the parent = $270,000 − $21,000 = $249,000.

Answer: NCI share of profit is $21,000 and profit attributable to owners of the parent is $249,000.

Exam tips

  • In Section A, the question often asks for only the NCI figure. Do that one calculation and move on rather than building a full consolidation.
  • Read the dates carefully. Net assets at the reporting date feed NCI. Net assets at acquisition feed goodwill.
  • If the subsidiary sold goods to the parent, adjust the subsidiary's figures for unrealised profit before applying the NCI %. If the parent sold them, the NCI is not affected.
  • In number entry questions, check whether the answer must be in $ or $000 and enter only digits in the format asked.
  • In Section B, show the NCI working clearly. Marks are given for the correct percentage, the correct base and the adjustments.

Non-controlling Interest: frequently asked questions

What is non-controlling interest in simple terms?

It is the part of a subsidiary's equity and profit that belongs to shareholders other than the parent. The group reports 100% of the subsidiary, so it must show how much of that is owned by outsiders.

How do you calculate NCI in the consolidated SOFP under the proportionate method?

Multiply the NCI percentage by the subsidiary's net assets at the reporting date. Adjust the net assets first for fair value changes and unrealised profit where the subsidiary made the sale.

Where does NCI appear in the consolidated financial statements?

In the SOFP it is shown within equity, separately from equity attributable to owners of the parent. In the statement of profit or loss it is shown as the split of profit for the year between owners of the parent and NCI.

Does NCI share in the parent's profit?

No. NCI shares only in the subsidiary's profit and net assets. The parent's own results belong entirely to the parent's shareholders.
