Washington CNN — Being president pays; $400,000 a year, in fact.

Washington's wealth in present-day terms has been estimated at more than a half-billion dollars.

That salary has increased over time. President Harry Truman left office in 1949 making $100,000. When Richard Nixon entered the White House in 1969 the salary went up to $200,000. It remained there for 30 years, until Congress doubled the presidential salary effective in 2001, when President George W. Bush took office.

Aside from the pay, theres the free transportation in the presidential limousine, Marine One and Air Force One. And dont forget the free housing in Washingtons most famous mansion, complete with a killer view of the Washington Monument, along with other perks a personal chef, for one.

When a president leaves the White House hes still on the government payroll, receiving an annual pension of about $200,000, health care, paid official travel and an office.

Rent for President Jimmy Carters Atlanta office is $102,000 per year, according to 2010 figures compiled by the Congressional Research Service. President George H. W. Bushs Houston office costs $175,000 per year. President Bill Clintons office in the pricey real estate market of New York City is $516,000.

Not too bad, huh?

But these taxpayer-funded benefits are nothing compared to the big bucks presidents rake in writing books.

“My Life” netted Bill Clinton a $15 million advance.

George W. Bush earned $7 million for the first 1.5 million copies of “Decision Points.”

Jimmy Carter has written 14 books.
