Money money money!

Reading "Around the World", and something struck me... didn't Fogg spend MORE money on his trip that he'd collect upon winning his bet?

The bet was 20,000 pounds, right?

But I'm itemizing his expenses, and they add up to more than 20,000 pounds, so even if he wins, he lost money, right? He's basically bleeding money to gain back some of it?

5000 bribes, bail, elephants etc.

750 Bribes to the Tankadere to get to Shanghai

8000 Passage on the Henrietta (2000 x 4 passengers)

12320 To buy the Henrietta and chop it up for fuel (1 pound=$4.87 in 1870)

100 Cab to get to the Reform Club

26170 Total expenditures vs. 20000 winnings

Am I missing something? I had originally thought that he was spending just enough money to ensure his win, but when he bought the entire Henrietta for $60,000, I had to say, "Stop! WHAT? lemme convert this to pounds and total this all up!"
