How much money do the US tax payers save when a former US president dies?

Answer 1

When you consider the annual budget is in the trillions even a million dollars is not a lot. That is about 33 cents per citizen I cannot cite any specifics but I would assume the secret service detail can't exceed $150,000 annually. I believe the pension is about $170,000 per year.
