Why Leaving $20,000 in Your Current Savings Account Could Cost You Almost $600 in a Year

A better rate won't change your balance overnight, but on $20,000 it can turn low interest into about $600 more a year.

Quick Read

$20,000 at 4.00% APY earns about $800 over one year, or roughly $67 a month.
The same $20,000 at 1.00% APY earns about $200 over one year, or roughly $17 a month.
That's a gap of about $600 a year on savings you might already have set aside.
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.

You might have a savings account you haven't thought about in months. It's doing its job in the background, holding cash for emergencies, bills, or the vague category known as life being life.

When there's $20,000 in that account, the rate matters more than it feels like it should. A few percentage points can separate coffee-money interest from hundreds of dollars over a year.

The cleaner decision is about matching the right dollars to the right job. Keep bills and your buffer easy to reach, then see whether the rest of your savings could earn more somewhere else.

$20,000 earning nothing could mean $66 a month, gone. Move it to SoFi and earn up to 4.00% APY on Savings for up to 6 months.¹ Earn up to 4.00% Annual Percentage Yield (APY) on one SoFi Savings account with a 0.90% APY Boost (added to the 3.10% APY as of 5/28/26) for up to 6 months.

Where the $600 goes

The nearly $600 comes from the spread between a low savings rate and a competitive one. Say your current savings account pays 1.00% annual percentage yield, or APY. On a $20,000 balance, 1.00% APY earns about $200 over one year.

Now say you find a high-yield savings account paying 4.00% APY, which is an achievable rate in the high-yield savings market right now. The same $20,000 at 4.00% APY earns about $800 over one year.

Subtract the two, and the difference is about $600 in missed interest over 12 months. The missing money doesn't leave your account as a penalty or charge. It never shows up because the account rate is doing less work than it could.

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

Find your actual APY first

Before you move anything, find the APY your current savings account pays today. The number often appears on your monthly statement, in the account details area of online banking, or on a rate information page inside your bank's app or website.

APY is the cleanest number to compare because it reflects the account's yearly return with compounding included. Your listed interest rate might look similar, but APY is usually the number banks use when showing what a savings account pays over a full year.

If your account is close to 1.00% APY, the $600 example could feel very relevant. If your account already pays closer to 4.00% APY, there's less urgency.

We did the research for you.

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.

No account fees: No overdraft fees.³ Overdraft Coverage is a feature automatically offered to SoFi Checking and Savings account holders who receive at least $1,000 or more in Eligible Direct Deposits within a rolling 31 calendar day period on a recurring basis. Eligible Direct Deposit is defined on the SoFi Bank Rate Sheet, available at <a href="https://www.sofi.com/legal/banking-rate-sheet">https://www.sofi.com/legal/banking-rate-sheet</a>.

Get paid up to two days early: Feel the magic of payday up to two days earlier — automatically — when you set up direct deposit.⁵ Early access to direct deposit funds is based on the timing in which we receive notice of impending payment from the Federal Reserve, which is typically up to two days before the scheduled payment date, but may vary.

Access additional FDIC insurance up to $3M: Typically, single-member deposit accounts are federally insured up to $250,000. With SoFi, FDIC insurance up to $3 million on deposits is available through a seamless network of participating banks.⁶ SoFi Bank is a member FDIC and does not provide more than $250,000 of FDIC insurance per depositor per legal category of account ownership, as described in the FDIC’s regulations. Any additional FDIC insurance is provided by the SoFi Insured Deposit Program. Deposits may be insured up to $3M through participation in the program. See full terms at <a href="http://sofi.com/banking/fdic/sidpterms">SoFi.com/banking/fdic/sidpterms</a>.

Some money should stay close

A higher APY gets attention, but convenience still matters. Money for rent, your mortgage, insurance premiums, tuition, or a credit card payment due soon probably belongs in the account that connects most smoothly to your monthly bills.

You might also want a small cushion in a familiar checking-linked savings account. That cushion can help cover a timing mismatch, a forgotten automatic payment, or the kind of surprise that arrives at 7 p.m. on a Friday.

The useful split is between money you need to grab quickly and money that's sitting there because it's always sat there. The first category buys convenience. The second category could earn more.

A split can still pay

Moving savings doesn't have to be an all-or-nothing decision. If you have $20,000, you might keep $5,000 close for bill timing and quick access, then move $15,000 into a high-yield savings account paying 4.00% APY, a rate available in the current high-yield savings market.

That moved $15,000 at 4.00% APY earns about $600 over one year. If the same $15,000 stayed at 1.00% APY for one year, it'd earn about $150.

So the split still creates about $450 in extra interest on the portion you moved. You keep the comfort of a cushion while making the rest of your savings compete a little harder.

Your money is already saved. Now see how it could be earning you hundreds per year.

Check costs before chasing APY

A higher APY is only useful if the account still works for your life. Before you move savings, look past the headline rate and check the terms that affect how much benefit you actually keep.

Pay special attention to:

Monthly maintenance charges or activity requirements
Minimum balance rules to earn the higher APY
Transfer or withdrawal limits that could slow you down
Required linked accounts or deposit rules
Balance tiers that pay the quoted APY only on part of your money

This is where the biggest number on the screen can lose some shine. If a higher rate comes with chores you won't realistically keep up with, the account could turn into a hassle instead of an upgrade.

Safety is not about familiarity

A familiar name or nearby branch can feel reassuring, but safety depends on coverage structure. For deposit insurance, the key details are the institution, the ownership category, and how much money you keep there.

As a general rule, FDIC insurance for banks covers up to $250,000 per depositor, per FDIC-insured bank, per ownership category, and NCUA insurance for federally insured credit unions covers up to $250,000 per depositor, per federally insured credit union, per ownership category. That limit is why a single account with $20,000 is usually a simpler coverage question than a household with several large balances spread across account types.

If your savings grows well beyond the example balance, pay closer attention to how accounts are titled and where the money sits. Familiarity feels nice. Coverage rules matter more.

Rates deserve a recheck

A good savings move today shouldn't become another account you ignore for years. Savings rates move as the rate environment changes, and promotions or special terms can also change the value of an account over time.

A simple reminder every few months can do the job. You might also recheck your APY after a noticeable market-rate shift, when a promotional period ends, or when your balance grows enough that the difference in interest becomes worth another look.

Think maintenance over perfection. Five minutes with your statement could be enough to spot when your savings account has quietly fallen behind.

Saving for a down payment, a wedding, or next April's tax bill? That money could be earning up to 4.00% APY for up to 6 months while it sits.¹ Earn up to 4.00% Annual Percentage Yield (APY) on one SoFi Savings account with a 0.90% APY Boost (added to the 3.10% APY as of 5/28/26) for up to 6 months.

Bottom line

If your current savings account pays around 1.00% APY, $20,000 earns about $200 over one year. If you can find a high-yield savings account paying 4.00% APY, a rate that's achievable right now, that same $20,000 earns about $800 over one year.

That's the nearly $600 gap. Keep the cash that needs instant convenience close, especially bill money and your personal buffer. Then make the rest of your savings prove it's in the right place by running the same one-year math on the amount you'd be comfortable moving or splitting.

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.
