WASHINGTON — Businesses owned by President-elect Donald Trump made $14.6 million off his campaign, according to a Bloomberg News analysis of Trump's most recent campaign finance reports.

If that sounds like a lot of money, consider this: Trump spent $66.1 million of his own money on his campaign, putting the venture at a $51.5 million personal loss.

The expenditures are legal, and in some cases, required under federal campaign finance law. Otherwise, Trump's use of his company's properties would constitute illegal in-kind contributions by his businesses to his campaign.

Here's how much of his own money Trump spent on his campaign

Still, the expenditures provide an interesting snapshot of the breadth of Trump business enterprises:

► $14.1 million on air travel, reimbursing Trump-owned TAG Air for the use of the Trump plane. That doesn't include $1.6 million from taxpayers for airfare for the Secret Service, which pays its own way on privately owned jets.

► $2.1 million for rent in Trump Tower for the campaign headquarters.

► $790,000 for facility rentals for Trump campaign events, including catering and meals at Trump-owned restaurants.

► $790,000 in lodging for staff at Trump hotels.

► $400,000 in payroll, reflecting the degree to which Trump's business and campaign operations were intertwined. Many employees of the Trump organization also did work on the campaign, and their time was reimbursed.

► $8,040.01 to Trump’s bottled water company, Trump Ice LLC.
