What is the average monthly U.S. Social Security retirement benefit?

How to get close to this number

Anchor on a working income and apply a replacement rate. Public pension systems typically replace somewhere around forty percent of average earnings, and median household income in this country is in the low eighties of thousands. A replacement fraction of a single earner's income gives a figure around two thousand a month.

The dependency figure in the explanation is the one that matters politically: for around forty percent of older Americans, this payment provides at least half of total income. A benefit that is supplementary in design is a primary income for a large minority, which changes what any adjustment to it means.

That is why the long-term funding gap is so politically difficult. A programme that a small share of recipients depend on can be reformed at the margins; one where four in ten recipients would lose half their income cannot. The dependency statistic, not the benefit level, is what makes the politics immovable.
