Straight answer
Here's the yardstick, from the source banks use: the FDIC publishes national average deposit rates every month. As of the July 2026 table, the national average savings rate is about 0.38–0.40% APY — while widely available high-yield savings accounts pay around 3.6%.
On a typical emergency fund, that gap is hundreds of dollars a year — our live example computes to $412 — for money that's just sitting there either way.

Dusklamp's Rate Lookout checks the FDIC benchmark against your bank's advertised rate and tells you when the gap moves. The private part — what the gap costs you — is computed on your own device, from a balance you type only into your own browser. It never reaches our servers. Not "we won't look" — can't.
