On $10,000, a savings account paying 3.50% APY earns $313 a year more than the 0.37% national average. The FDIC's national average savings rate was 0.37% in its September 21, 2026 release. The 3.50% is our assumed example rate, not a quote from any bank. The deposit insurance is the same at both kinds of bank: $250,000 per depositor, per insured bank, per ownership category.

What the FDIC says the average account pays

The FDIC publishes National Rates and Rate Caps monthly. The September 2026 release:

Product	National average rate	Earnings on $10,000 a year
Interest checking	0.07%	$7.00
Savings	0.37%	$37.00
Money market	0.63%	$63.00
12-month CD	1.73%	$173.00
Example high-yield savings (our assumption)	3.50%	$350.00

Interest earned in one year on $10,000

FDIC national averages, September 21, 2026, against an assumed 3.50% example rate. Balance times rate, no compounding.

The national average is a figure for all banks. It is not what a large bank pays you, and the FDIC does not name banks in it. For a specific bank's rate, use that bank's own rate page, and check the date.

The gap in dollars

The gap is balance times the rate difference. At 3.50% against 0.37%, the difference is 3.13 points.

Balance	Extra interest in a year
$5,000	$156.50
$10,000	$313.00
$25,000	$782.50
$50,000	$1,565.00

Rates move. On $10,000 the extra interest is $263 if the high-yield rate is 3.00% and $363 at 4.00%. Over five years with no deposits and annual compounding, $10,000 grows to $11,877 at 3.50% and $10,186 at 0.37%, a gap of $1,690.

$10,000 over five years, 3.50% against 0.37%

Annual compounding, no deposits. The 3.50% rate is an assumption. The line shown is the 3.50% balance; the 0.37% balance reaches $10,186.

Compare APY, not the stated rate

Federal rules define the annual percentage yield. Regulation DD, Appendix A to 12 CFR Part 1030 gives APY = 100 [(1 + Interest/Principal)^(365/Days in term) - 1]. It is the interest you earn over a year including compounding. Two accounts with the same APY pay the same.

The compounding schedule barely matters. A 3.50% nominal rate compounded monthly yields 3.557% APY. Compounded daily it yields 3.562%. That is a difference of $0.50 a year on $10,000. The rate is what moves your money.

Insurance is the same either way

The FDIC insures deposits at $250,000 per depositor, per insured bank, per ownership category. Single accounts, joint accounts, retirement accounts and trusts are separate categories. Since April 1, 2024, trust accounts (informal POD accounts, revocable and irrevocable trusts) share one calculation: $250,000 per eligible beneficiary, up to $1,250,000 at five or more beneficiaries. Credit unions are covered the same way by the NCUA's Share Insurance Fund, up to $250,000 per member-owner, per institution, per ownership category.

The FDIC lets you check whether a bank is insured with BankFind or by phone at 1-877-275-3342. Do that before moving a large balance to an unfamiliar name.

Insurance applies per bank. If you use an app or brokerage that holds your cash at another bank, find out which bank holds it and confirm that bank is insured.

What to check before you move money

Is the rate promotional? Some rates apply only for a few months or above a minimum balance.
Are there tiers or conditions? Some accounts require direct deposit or pay the top rate only up to a cap.
How long do transfers take? External transfers can take a few business days.
Is the rate variable? Savings rates change without a contract, so look again once or twice a year.

Where cash should sit

Money for	Reasonable home
Bills this month	Checking
Emergencies, see how much emergency fund you need	Savings, kept liquid
A known expense in 1 to 3 years	Savings or a CD
Goals 5 years or more away	Not a savings account

The last row follows from inflation. The Bureau of Labor Statistics reported that consumer prices rose 3.4% over the 12 months to August 2026. A 3.50% savings rate beats that by 0.1 point. The 0.37% average loses about 3 points of buying power a year. Cash earns a real gain only at the top of the market, so use savings accounts for money you may need, and see pay off a loan early or invest for the rest.

Frequently asked questions

What is the national average savings rate?

The FDIC put it at 0.37% on September 21, 2026. Interest checking averaged 0.07% and money market accounts 0.63%.

How much more does a high-yield savings account earn?

At an assumed 3.50%, it earns $313 a year more than the 0.37% average on $10,000, and $782.50 more on $25,000. The actual gap depends on the rate you find.

Is a high-yield savings account safe?

Yes if the bank is FDIC insured or the credit union is NCUA insured, up to $250,000 per depositor, per institution, per ownership category. Check the institution on FDIC BankFind first.

Is APY or the interest rate better to compare?

APY, because it includes compounding and is defined the same way at every bank under Regulation DD. A 3.50% rate compounded daily is 3.562% APY.

Why is my big bank savings rate so low?

Banks set savings rates themselves, and the FDIC national average of 0.37% shows many pay little. Whether yours does is on your bank's own rate page.

How are trust accounts insured?

Since April 1, 2024 the FDIC covers $250,000 per eligible beneficiary, up to $1,250,000 for five or more, across an owner's trust accounts at one bank.

Does moving savings affect my credit score?

No. Deposit balances are not credit report items, and a savings balance is not a credit score factor. Ask the bank whether it runs any credit check when you open the account.
