What is Donald Trump's Net Worth? $100 Million Loss Marks Two Years of Consecutive Decline

President Donald Trump's net worth took a $100 million tumble to $2.8 billion over the past year to its lowest amount since his presidential campaign, according to a report.

The dip from $2.9 billion last June—which the Bloomberg Billionaires Index calculated through information from lenders, annual reports, property records and Trump's May 16 financial disclosure—marks the second consecutive year of decline and is largely attributed to lower revenue at his properties and golf courses since he became president.

Bloomberg, which started tracking Trump's net worth in 2015, on Thursday reported that the biggest losses, amounting to $220 million, came from Trump Tower in midtown Manhattan and adjacent 6 E. 57th St., which lost NikeTown as its tenant.

Trump's 16 golf courses and resorts plummeted in value by $70 million, and together are worth around $650 million, according to the report.

Trump Organization spokeswoman Amanda Miller criticized Bloomberg's methodology in estimating the value of Trump's Manhattan buildings, saying the borough-wide data it used reduces their worth. "The location of a property affects the rents it can achieve," Miller told the media outlet.

It is not the first report that Trump's presidency has not helped his businesses, which he refused to divest from, unlike past presidents. Revenue to Trump's golf courses has been flat, according to his financial disclosure report released mid-last month.

The President did not make the Bloomberg Billionaires Index of the 500 richest people in the world, from American tech entrepreneur Jeff Bezos at number one with a $136 billion net worth, to Swedish real estate businessman Fredrik Lundberg at number 500 with a $4.01 billion net worth. The wealth of the group was up 9.4 percent since last year.

Trump has claimed his net worth is much higher. In June 2015, he claimed his net worth was about $8.7 billion, and a month later filed financial disclosure forms that reflected his net worth surpassed $10 billion.
