- $75,000 at a 4.00% annual percentage yield (APY) earns about $16,249 over five years, or about $3,250 a year.
- The same $75,000 in a 0.01% APY example earns about $38 over five years, or about $8 a year.
- That's a gap of about $16,211 on money that could still stay in a savings account.
- 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've ever left a big cash cushion in the same familiar account for years, the logic probably made sense at the time. The money was visible, easy to reach, and safely out of your spending account. That simplicity has real value.
But when the balance is $75,000 and the rate is 0.01%, the account's convenience starts carrying a dollar cost. Compared with a high-yield savings account, or HYSA, that low-rate example can turn into a five-year gap large enough to make the account worth a second look.
The useful question is which part of your cash needs instant access, which part can sit in higher-yield savings, and whether the interest you're giving up is worth the comfort of leaving things alone.
A familiar account can be expensive
A 0.01% savings-rate example feels harmless because the missing interest doesn't show up as a bill. Nobody sends an invoice for the money your cash didn't earn. Your savings account balance just sits there, doing almost nothing, while better-paying savings accounts work on the same basic job.
That's what makes a large low-rate balance easy to ignore. The account still looks stable, so the problem feels theoretical until the math turns the rate difference into dollars.
| If you have | One year at 0.38% APY (national average) | One year at 3.80% APY (example) | You are leaving behind |
| $10,000 | $38 | $380 | $342 |
| $25,000 | $95 | $950 | $855 |
| $40,000 | $152 | $1,520 | $1,368 |
| $50,000 | $190 | $1,900 | $1,710 |
| $100,000 | $380 | $3,800 | $3,420 |
The gap is about $16,200
Start with the familiar account. If $75,000 earns 0.01% APY for five years and interest compounds annually, the balance grows to about $75,038. That means the account earns about $38 total over five years.
Now compare that with a high-yield savings account paying 4.00% APY, a rate currently available on some high-yield savings accounts (as of 09/02/26). If the same $75,000 earns 4.00% APY for five years and interest compounds annually, the balance grows to about $91,249. That's about $16,249 in interest.
The gap between those two outcomes is about $16,211. Put another way, the same $75,000 earns about $8 a year at 0.01%, or about $3,250 a year at 4.00% when averaged across the five-year result.
That's why APY is the useful number here. APY lets you compare accounts on a compounding basis, which matters when you're looking at several years instead of one monthly statement.
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.

It won't buy the average car
A car comparison needs a reality check. Kelley Blue Book reported that the average new-vehicle transaction price was $49,766 in October 2025, so the roughly $16,211 five-year interest gap doesn't pay for the average new car.
Even so, the number still matters. About $16,211 could be a serious car down payment, several months of household expenses, or the difference between using cash and taking on more debt. The average-new-car version stretches the claim, but the lost-interest math still deserves attention.
Put each dollar on a clock
Before moving money, sort the $75,000 by when you might need it. A high-yield savings account can be a strong place for cash that needs to stay available, but timing decides whether that account fits the job.
Use a simple clock:
- Money needed this week should stay where you can use it immediately, especially if it covers groceries, rent, payroll transfers, or a payment that's already scheduled.
- Money for next month's automatic bills belongs somewhere predictable, because a transfer delay at the wrong moment can create an avoidable headache.
- Emergency reserves can be a strong HYSA candidate if you can access the money quickly enough for the kinds of emergencies you're planning for.
- Cash for taxes, tuition, insurance premiums, or a home repair fund often fits well because the money has a near-term job and sits for months.
- Down payment money tied to a closing or purchase deadline should follow the instructions for that transaction, even if the rate is boring.
- Money you won't need for five years or more may deserve a different long-term plan, because savings accounts are built for access and stability rather than long-term growth.
So sort the $75,000 by fit rather than moving all of it into a HYSA. Focus on which dollars can earn more without getting in the way of bills, emergencies, or a deadline that's already on the calendar.
The practical snags are checkable
The annoying parts are real, but most are easy to check before you move eligible cash. A few minutes with the account terms can tell you whether the better rate comes with friction you don't want.
Check these items first:
- Transfer timing: Some account providers describe standard ACH settlement for external transfers as taking 1 to 2 business days. If you need same-day spending access, keep that portion where you can reach it the same day.
- Emergency access: A HYSA can work for emergency savings if you know how you'd pull money out. Some people keep a smaller buffer in checking and keep the larger emergency reserve in savings.
- Deposit insurance structure: Confirm whether the account is covered by the appropriate federal deposit or share insurance program, and check how ownership-category rules apply if you have other deposits at the same institution.
- Minimums and fees: Current high-yield savings listings show that minimum deposit and balance requirements vary, while fee structures are account-specific. Look for terms that match how much you actually plan to keep there.
- Rate movement: Savings rates can move, so don't treat today's 4.00% example like a five-year guarantee.
The tradeoff is pretty plain. You might give up some instant familiarity, and the rate isn't locked for five years. In exchange, money that fits the HYSA job could earn meaningfully more while staying in a savings account.
Run your own five-year test
You don't need a perfect spreadsheet to get a useful answer. The earlier $16,211 gap used annual compounding, but a simple-interest estimate gives you a fast gut check.
$ gap estimate = balance x rate difference x years
For example, comparing $75,000 at 0.01% with $75,000 at 4.00% for five years gives you a rate difference of 3.99%. So the rough estimate is:
$75,000 x 0.0399 x 5 = $14,963
That rough estimate comes in below the compounded result, but it tells the same story: the low-rate account is expensive over time.
Try a quick audit:
- Check the current rate on your existing savings account.
- Mark the cash you need this week or next month.
- Identify the cash that can sit in savings for months or years.
- Compare your current rate with a HYSA rate you can actually find.
- Estimate the dollar gap, then decide whether convenience is worth that price.
Bottom line
The five-year math is hard to shrug off. $75,000 at 0.01% APY earns about $38 over five years, while the same $75,000 at a 4.00% high-yield savings example earns about $16,249.
That's about $16,211 more for cash that still belongs in savings if the timing fits. Sort your money first, then compare the lost-interest number with the convenience of leaving everything where it is.
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.
