How Much You're Losing by Not Shopping Your Savings Rate (by Income)

Most coverage of the savings-rate gap uses one illustrative balance, usually $25,000, and reports one dollar figure. That's a fine way to make the point that the gap is real, but it describes almost nobody's actual account -- the real median American bank balance is $7,850, not $25,000, and it varies by roughly 139x across income brackets. This piece uses real Fed-sourced balances instead of a flat example, so the dollar figure you see is closer to what the gap is actually worth for someone at your income level, not a hypothetical. This page is reviewed by the SwitchWize Editorial Team; the figures are sourced below with dates.

The gap is fixed. The stakes aren't.

As of August 2026, the best widely-available savings APY is 4.10%, against a FDIC national-average savings rate of 0.38% -- a 3.72-point gap, sourced live from SwitchWize's Bank Gap Index. That gap doesn't care about your income or your balance; it's the same 3.72 points whether you have $500 sitting at a big bank or $500,000. What changes is what that percentage is worth in real dollars, and that depends entirely on how much money is actually behind it.

That's the problem with a single flat example balance: it makes the gap concrete, but concrete for whom? Using the average balance by income bracket -- a direct recomputation of the Fed's own 2022 Survey of Consumer Finances microdata -- instead of a hypothetical $25,000, the real picture looks like this:

The 40th-60th percentile bracket -- roughly the median American household -- is losing about $268 a year, not because of anything they're doing wrong, but purely because of which account the money happens to sit in.

Why the flat-example approach understates it for some people, overstates it for others

A single illustrative balance is a legitimate simplification -- it's easier to write and easier to remember than a six-row table. But it has a real cost: for anyone below the median, a $25,000 example overstates what they're actually losing, which can make the whole argument feel disconnected from their real finances ("I don't have $25,000 sitting in savings, so this doesn't apply to me"). For anyone above the median, especially the top 10-20% of households by income, it dramatically understates the real number -- someone with $111,600 in transaction accounts at the national average rate is leaving over $4,100 a year on the table, more than 16 times the flat-example figure.

Neither error is intentional; it's just what happens when one number stands in for a distribution that spans 139x. Using the real bracket data instead doesn't change the underlying math -- the rate gap is still the rate gap -- it just makes the dollar figure honest for more readers.

What actually closes the gap

The fix costs nothing and takes minutes: move the balance (or open a new account and redirect deposits) to an account paying closer to the best widely-available rate instead of the national average. FDIC insurance limits apply the same way regardless of which insured bank holds the money, so there's no meaningful risk tradeoff -- the entire 3.72-point gap is unpriced convenience, not compensation for anything.

The honest counterargument

A few real limits are worth naming. The balances above are medians for an income bracket, not a prediction of any individual's account -- age, region, debt, and how much of someone's liquidity sits in checking versus savings all shift the real number for a given household. The 3.72-point gap itself is a snapshot as of August 2026 and will move as rates move; the live dataset always reflects the current figure, this article does not. And some balances genuinely need to stay in checking for cash-flow reasons rather than earning the top savings rate -- this isn't a claim that every dollar should move.

None of that changes the direction of the finding. Whatever bracket you're actually in, the gap between the account you have and the account you could have is real, it's measurable, and closing it doesn't require earning more or saving more.

Methodology

The 3.72-point rate gap (4.10% best widely-available vs. 0.38% FDIC national average) comes from SwitchWize's Bank Gap Index, the same live inputs used across our rate-spread indices. Balance-by-income-bracket figures are SwitchWize's own direct recomputation of the Federal Reserve's 2022 Survey of Consumer Finances public microdata (see the average balance by income bracket report for full methodology). Per-bracket annual gap = bracket median balance x (best available APY - national average APY). Because both the rate gap and the balance figures are wave/date-specific, treat the exact dollar amounts as illustrative of the current gap, not a permanent constant.
