The Savings Gap: what the big banks pay you, and what everyone else does
By Paul Knag, Founder, RateZip ·
As of September 1, 2026, Chase, Bank of America, Wells Fargo pay an average of 0.02% APY on savings. The best online savings rate RateZip tracks, CIT Bank, pays 4.1% APY. That is a 408 basis point gap. On a $50,000 balance it works out to $2,040 of forgone interest in a single year.
The number usually quoted for “the average savings account” blends thousands of institutions and arrives weeks late. This page measures something different and more useful: the gap an actual shopper faces today, comparing posted rates captured on the same day. RateZip has tracked both sides every day since July 16, 2026 — 48 days — and the gap has not closed once.

Figures are simple interest on a static balance, before taxes, and are illustrative.
Why do big banks pay so little on savings?
Branch-network banks fund themselves largely from checking and savings deposits that customers leave in place for convenience, so they have little competitive pressure to price up. Online banks have no branch overhead and must win deposits on rate alone, so they price near the short-term rate environment. That structural difference, not a temporary promotion, is why the gap in RateZip's tracking has persisted every single day it has been measured.
Is the savings gap getting wider or narrower?
Across RateZip's daily tracking since July 16, 2026, the gap peaked at 413 basis points on July 16, 2026 and was narrowest at 408 basis points on July 22, 2026. It currently sits at 408 basis points.
Methodology
RateZip snapshots the publicly posted savings APYs on its own deposit tables every hour. For each day we take each bank's highest posted savings APY, average the three branch-network banks we carry as editorial comparison rows (Chase, Bank of America, Wells Fargo), and compare that average with the highest APY among all other tracked banks on the same day. Because both sides come from the same day's snapshot, the gap never mixes as-of dates. Year-one dollar figures are simple interest on a static balance, before taxes, and are illustrative only.
Current rates for every tracked bank, with 16 years of history, are on the RateZip Rate Index. Weekly notes on which banks moved are in Rate Moves.
