If you believe that being President cost him money, count yourself as one of his suckers.
Forbes Magazine is a widely accepted source for tracing the monetary worth of the rich. Trump was worth about $3.5 billion when he ran for office. In 2016 New York real estate lost value, costing him about $400-million. In Europe, his property lost money because of the image problems they had during his run for office. He lost another $500-million from decreased revenues and value of hotels because of the Coronavirus Pandemic. But, the entire industry lost money, not just President Pandemic. Forbes says he is worth about $3-billion still.
His "Save America PAC," has taken the place of his foundation that he was forced to dissolve due to illegal use as his personal ATM. He signed an agreement to never have another private foundation, to avoid further prosecution. But, he said nothing about not using a PAC in the same way. The way his PAC is set up, he can spend the over $200-million it has raised recently on almost anything he wants, including daily expenses, air travel, etc.
