President Donald Trump is no stranger to boasting about his wealth.

“I’m really rich,” he announced, after launching his presidential run in 2015.

But how exactly does Trump earn his income?

Business Insider poured through the president’s executive branch personnel public financial disclosure report to find out more about how much money he earns – and how he makes it.

The 98-page document, which is available on the Center for Responsible Politics' website, reveals the president earned anywhere from $597,396,914 to $667,811,903. The information was voluntarily provided to the Office of Government Ethics and covers January 2016 through Spring 2017.

The president never released his tax returns - despite promising to, during the election. The White House says it is because of an audit, a claim disputed by tax experts. The lack of clarity has sparked speculation that Republicans' ongoing tax reform efforts - which have proved deeply unpopular with the public - will benefit the president's own finances.

While Trump has claimed the bill will hurt him, White House press secretary Sarah Huckabee Sanders admitted to reporters it "could" help his business interests, Business Insider reported.
