$10,000 in a big bank earning almost nothing

Interest earned in one year at a rate of 0.01%: $1

For better or worse, big banks typically don’t have to jockey for new customers. The name recognition alone of a national bank is enough of a draw that big banks don’t have much incentive to offer competitive perks like high-yield savings accounts.

As a result, many big banks offer interest rates as low as 0.01%. If you have $10,000 in savings, you’ll earn $1 a year (based on a simple interest calculation, not compounding interest). 

Worse, many big banks charge a monthly or yearly savings account maintenance fee — so storing your savings in a low-interest savings account with a big bank could lose you money.

$10,000 in a bank earning the national average rate

Dragana Gordic/Adobe A financial advisor

Interest earned in one year at the current national average rate of 0.46%: $46

The Federal Deposit Insurance Corporation (FDIC) is the independent federal agency that backs bank account deposits and oversees banks and credit unions. 

The FDIC also calculates monthly interest rate caps for banking products, which include savings accounts, money market accounts, certificates of deposit (CDs), and interest checking accounts.

For March 2024, the FDIC monthly rate cap for savings accounts is 0.46%. If you deposit $10,000 in an account with that interest rate, you’ll earn $46 in one year.

Again, this is a simple interest calculation. If your savings account earns compound interest (and most do), your interest also earns interest. Whether your interest compounds monthly, quarterly, semi-annually, or annually impacts the amount of interest you’ll earn.

$10,000 in a competitive high-yield savings account

Interest earned in one year at the competitive rate of 4.00%: $400

Many non-traditional, new, or online banks use high-yield savings (and even checking) accounts to get new customers interested in their banking services. 

While 4.00% is considered a competitive rate — especially compared to almost comically low big-bank rates — it’s entirely possible to find high-yield savings accounts with even higher rates.

Of course, you should carefully vet banking options to ensure you choose the best bank for you, not just the bank with the highest interest rate.

If you open a high-interest savings account with a rate of 4.00%, deposit $10,000, and don’t touch that money for an entire year, you’ll earn $400 worth of simple interest on your principal deposit (about $408 if compounded daily).

Resolve $10,000 or more of your debt

Credit card debt is suffocating. It constantly weighs on your mind and controls every choice you make. You can end up emotionally and even physically drained from it. And even though you make regular payments, it feels like you can never make any progress because of the interest.

National Debt Relief could help you resolve your credit card debt with an affordable plan that works for you. Just tell them your situation, then find out your debt relief options.1

$50,000 in a big bank earning almost nothing

Interest earned in one year at a rate of 0.01%: $5

Earning $5 on a deposit of $50,000 is better than earning either nothing or $1 … but not by much, especially if you’re paying a monthly service fee just to keep the account.

Interest earned in one year at the current national average rate of 0.46%: $230

There’s more than one reason to leave your savings untouched for as long as possible, but one is definitely that the more money you’re able to deposit, the higher your return will be. 

At a fixed rate of 0.46%, you could earn $230 in one year or over $1,000 in five years with practically no effort required.

Interest earned in one year at the competitive rate of 4.00%: $2,000

Yes, you read that right. Depositing $50,000 into a low-interest savings account earns you around $5 — but depositing that same amount into a high-yield account with a different bank nets you $2,000 in simple interest alone (about $2,040 if compounded daily).

$100,000 in a big bank earning almost nothing

N Lawrenson/ Person talking to financial advisor

Interest earned in one year at a rate of 0.01%: $10

The $10 of interest you earn by depositing $100,000 with a big bank demonstrates that it isn’t necessarily the amount of money you save that counts — it’s where and how you store that money. 

And if increasing your saving ability is one of the main things you look for in a bank, just know that you’ll rarely find it with a big bank’s savings account.

Interest earned in one year at the current national average rate of 0.46%: $460

$460 isn’t the highest amount you could earn on a $100,000 savings deposit, but it’s a respectable amount to earn over a year (especially compared to $10). 

If your current bank or credit union offers interest rates around the national average and has a series of other perks for long-term customers, sticking with that bank might be a wise choice for your financial future.

Interest earned in one year at the competitive rate of 4.00%: $4,000

$4,000 (about $4,080 if compounded daily) is an incredible amount to gain by doing nothing more than depositing cash into an account.

That's precisely why looking into a high-yield savings account with a non-traditional bank could be the smartest move you make to boost your retirement savings.
