There isn’t a single official “net worth” number for the 5 million richest Americans, because the cutoff depends on the wealth data source and whether you mean households or individuals. But as a rough guide, recent reporting suggests the top 10% of U.S. households starts around $1.8 million in net worth, and “rich” is often described by Americans themselves as around $2.3 million or higher.

What that means for the top 5 million

The U.S. has over six million high-net-worth individuals with at least $1 million in investable wealth, so the “5 million richest Americans” would include a very broad slice of people above that level, not just billionaires.

Practical estimate

A reasonable shorthand is:

  • Lower end: around $1 million to $2 million net worth.
  • Middle of the group: several million dollars.
  • Upper end: far above that, including ultra-wealthy households and billionaires.

Bottom line

If you mean the cutoff for entering the 5 million richest Americans, it is probably somewhere around the low millions of dollars , but there is no single public number that precisely defines that exact rank. TL;DR: A good estimate is that the 5 million richest Americans start around the $1M–$2M+ net-worth range, with the top far beyond that.
