The Clintons provided the modern blueprint for how to get rich once a U.S. President leaves office, and former President Barack Obama is following their example on his way to a small fortune of his own. 

Bloomberg reported this week that Obama recently gave an address to private equity firm Carlyle Group LP. That speech follows up another one he gave to clients of Northern Trust Corp. for $400,000 last month. Obama is expected to be paid another $400,000 for a speech at a healthcare conference sponsored by Cantor Fitzgerald next week. 

It's not bad work if you can get it, and though Obama entered the White House with a rocky relationship with Wall Street's bigwigs, his working relationship with them now stays "true to his values," Kevin Lewis, a spokesman for the former president told Bloomberg. 

Timing is everything for many of these speakers. Current President Donald Trump, for instance, was able to charge $1.5 million for speeches he made in 2008 at the height of the popularity of his television show. 

Here is a look at 10 other speakers cleaning up. 

10. Al Gore

Environmentalist and former Vice President Al Gore has been able to command a $100,000 fee for his speeches.
