- $40,000 at 3.80% APY earns about $1,520 over one year, or roughly $126 a month.
- The same $40,000 at the FDIC national average savings rate of 0.38% APY earns about $152 a year, or about $12 a month.
- That is a gap of about $1,368 a year on a balance you never have to lock up.
-
At the national average savings rate of 0.38% (as of 06/15/26), $20,000 earns $76 a year. The same balance could earn up to nine times more with a SoFi Checking and Savings account. See SoFi®'s current rate.
If you have $40,000 sitting in an older savings account, there is a good chance it paid you about $12 last month.
Move that same $40,000 into a high-yield savings account paying 3.80% APY and the number becomes about $126 a month, or roughly $1,520 over one year. Same balance. Same ability to pull the money out when you need it. The difference is about $1,368 a year, and it comes down to one number your current bank is not advertising.
Here is the math, what your own balance would earn, and how to move the money.
What $40,000 earns in a year
Start with the annual percentage yield, or APY, listed on the account. It bundles the interest rate and the compounding schedule into a single one-year number, which is why it is the figure to compare across savings accounts. If an account page pushes a promotional phrase harder than it shows the APY, slow down and find the APY.
$40,000 x 3.80% APY for one year = about $1,520
That puts the balance at about $41,520 after a year, and works out to roughly $126 a month in interest while the money sits there.
Now compare that with what your cash earns today. If your current account lists an APY, use that number. If you cannot find it, the FDIC national average savings rate is 0.38% APY (as of 06/15/26). At that rate, $40,000 held for one year earns about $152, or about $12 a month.
Same $40,000. Same year. About $1,368 apart.
Find your balance in this table
$40,000 is the example, but the gap scales with whatever you have parked. Here is one year of interest at both rates:
| If you have | One year at 0.38% (national average) | One year at 3.80% APY (example) | You are leaving behind |
| $10,000 | about $38 | about $380 | about $342 |
| $25,000 | about $95 | about $950 | about $855 |
| $40,000 | about $152 | about $1,520 | about $1,368 |
| $50,000 | about $190 | about $1,900 | about $1,710 |
| $100,000 | about $380 | about $3,800 | about $3,420 |
Every row is the same calculation: the balance, the APY, and one year. The high-yield column uses the 3.80% example APY; the national average column uses the FDIC figure of 0.38% (as of 06/15/26).
The rate window may not stay open
One thing to know before you decide: high-yield savings rates float. They are not locked in, and they move with the broader rate environment, which means a rate cut would pull savings yields down too.
That argues for moving sooner rather than later. Interest you collect while rates are higher is yours to keep, and savings accounts generally do not tie the money up, so you are not committing to anything you cannot undo.
Having your checking and savings accounts with the same financial institution can make money management a lot simpler. SoFi® was our 2026 award winner for Best Checking and Savings Combo because it delivers on interest and additional features.

How to move your money in about 10 minutes
- Compare accounts on APY first. Then check the fee schedule and any minimum balance requirement, and confirm the institution carries FDIC or NCUA coverage.
- Open the account online. You will generally need your ID, your Social Security number, and the routing and account numbers for your current bank.
- Link your existing checking account. ACH transfers typically take one to three business days, while same-day ACH depends on cutoff times and operating days.
- Move the portion you do not need right away. That may not be all $40,000, which is the next section.
- Keep your current bank if you like it. Nothing requires you to close an account you already use.
Before you move all $40,000, check four things
- Near-term bills. Transfers take time, so money that has to move today belongs in checking. Leave enough there that you are not scrambling.
- Fees. Check the fee schedule for recurring charges, transfer charges, and balance rules. If a monthly charge is unavoidable, multiply it by 12 and subtract that annual cost from your one-year interest estimate.
- Taxes. The IRS generally treats savings interest as taxable interest income. Multiply the interest earned by your own tax rate estimate and subtract it when you compare accounts.
- Insurance limits. The FDIC standard limit is $250,000 per depositor, per insured bank, per ownership category, and the NCUA standard share insurance limit is $250,000 per share owner, per insured credit union, per ownership category. Deposits in the same ownership category at the same institution are added together, so if you already hold $230,000 there, adding $40,000 brings that category to $270,000, which is $20,000 above the standard limit.
If you will need some of the cash sooner, the math still works. It just scales. $10,000 at 3.80% APY for six months comes to about $190.
Money you will not touch for a year has another option
If the $40,000 truly is not needed for 12 months, a one-year certificate of deposit is worth comparing. The tradeoff is access. A CD sets a term and can offer more rate certainty for that term, but taking money out early may trigger an early withdrawal penalty. IRS guidance for certificates of deposit refers to account maturity and interest that may be subject to a penalty for early withdrawal.
For an emergency fund, or any money with an uncertain deadline, the flexible option usually wins.
Bottom line
At 3.80% APY, $40,000 in a high-yield savings account earns about $1,520 over one year, or about $126 a month. At the FDIC national average savings rate of 0.38% (as of July 20, 2026), the same $40,000 earns about $152, or about $12 a month.
That is about $1,368 a year on money you keep full access to, for a transfer that takes about ten minutes. Every month the cash stays where it is, you give up roughly $114 of that difference.
Keep next month's bills in checking, subtract any fees and taxes, confirm your total deposits fit the coverage you are counting on, then move the rest. The easiest raise you will get this year is the one your current bank is quietly declining to give you.
Would You Spend Ten Minutes for $1,465?
That's roughly the year's difference on $40,000 between the national average and the up-to-4.00% rates available now. And ten minutes isn't a figure of speech. You just provide some information, like your name, address, Social Security number, and the account your deposit money's coming from. But rates are variable and follow the market, which is why the only number worth acting on is today's. Compare the current top accounts here.
