Washington (CNN) Michael Bloomberg has spent an astonishing $464 million on his presidential campaign -- which he launched just 10 weeks ago, as he noted on the debate stage Wednesday night.

That debate was the major debut of Bloomberg's presidential campaign -- and he came off a bit rusty. His debate performance has been widely panned. Bloomberg has spent the most money of anyone on that stage, and he spoke the least , coming in at 13 minutes and 6 seconds, just behind Joe Biden.

Let's do a little math ( Andrew Yang-style ) on how much Bloomberg's campaign spent to appear onstage:

$590,330.78 per second. That works out to $35,419,847 per minute! $464 million (thanks to Bloomberg campaign's filing released Thursday) ÷ 13 minutes and 6 seconds (or 786 seconds) of speaking time =. That works out to $35,419,847 per minute!

The wild thing about Bloomberg is that his success basically has nothing to do with his debate performance (unlike fellow billionaire candidate Tom Steyer, who advertised, in part, to get ON stage ). Bloomberg has so much money that he can use his own preferred platforms to get his message out the way he wants to, through paid media, rather than the traditional earned media methods, like sit-down interviews and town halls, where he'd face tougher scrutiny.
