Former President Barack Obama will cost taxpayers $1,153,000 next year, according to a Congressional Research Service memo.

That amount will make Obama's expenses the highest of the five living ex-presidents, the Washington Times reported.

The Former Presidents Act, which became law in 1958, provides former White House occupants with lifetime benefits after leaving office. Each ex-president receives a base pension of $205,700 annually, but the budget requests they submit to Congress may also address additional expenses, such as for staff salaries, office allowances, travel and Secret Service protection.

Obama’s $1,153,00 budget request for 2018 is nearly $100,000 more than that of former President George W. Bush, and around $200,000 higher than for former President Bill Clinton.

Former President George H.W. Bush has requested $942,000, while former President Jimmy Carter comes in at $456,000, the Times reported.

A large portion of the former presidents’ budgets go toward leasing office space, such as the $536,000 cost for Obama’s office in Washington, $518,000 for Clinton’s setup in New York City, and $497,000 for Bush 43's office in Dallas.

Bush 41's space is much cheaper, located in Houston and costing $286,000, while Carter’s space in Atlanta is a relative bargain at only $115,000, the Times reported.
