What is Controlling Interest?
Controlling Interest in the company is when a single shareholder or the group of shareholders who are acting collectively own a majority of the voting shares (more than 50 % ) of a company.
Suppose a person or the group person who has less than 50% of the ownership in the company can still have the controlling interest if a significant portion of voting shares is there with that person or the group of persons. It is so because, in many cases, share does not carry the voting rights in meetings of the shareholder.
Example
Mr. X is holding the 5,100 shares in the company XYZ Ltd. The total outstanding shares of the company XYZ Ltd. in the market is $10,000. Whether Mr. X has controlling interest in the company XYZ or not? All shares have equal votes.
Solution:
In the present case the percentage of holding by Mr. X in the company XYZ is calculated as below:

4.9 (1,067 ratings) 250+ Courses | 40+ Projects | 1000+ Hours | Full Lifetime Access | Certificate of Completion
Holding Percentage = Shares of Mr. X / Total outstanding shares of Company XYZ Ltd;
- Holding Percentage = 5,100 / 10,000 * 100
- Holding Percentage = 51%
Since Mr. X is holding at least 50 % of voting shares of the given company XYZ Ltd. plus one, so Mr. X is having controlling interest in the company;
Real-World Example

It is one classic example of the controlling interest by Michael Dell in the company Dell technologies.
