What is a Retired presidential salary?

Answer 1

From Wikipedia:

Before passage by Congress of the Former Presidents Act (FPA) in 1958, retired Presidents did not receive a pension. All living Presidents in 1959 began to receive a pension of $25,000 per year, an office and a staff. The pension has increased numerous times with Congressional approval. Retired Presidents now receive a pension based on the salary of the current administration's cabinet secretaries (Executive Level I), which is $191,300 as of 2008.[22] Some former Presidents have also collected congressional pensions.[23] The FPA, as amended, also provides former presidents with travel funds and mailing privileges.
