Forbes has been calculating Trump's fortune, and last September they gave the figure of $7.3 billion in the article "The Definitive Net Worth of Donald Trump", as his fortune shot up in the first nine months of his presidency with $3 extra billions made on his cryptocurrency ventures, his legal team successes and the licences his branding company has sold to foreign developers. The report includes some personal and family data, like his pension fund ($2 million) and the $50,000 annual interest that his three eldest children pay him for loans that amount to $5 million.
If you want to find out the details of Trump's assets and liabilities, you can read the Forbes article, "The Definitive Net Worth of Donald Trump" which is short, but it is recommended for C2 students for its abundant business & finance vocabulary, where you will encounter interesting American-spelt expressions like:
