What is a High Yield Savings Account (HYSA)?

Two savings accounts. Same $1,000. One earns pennies, the other earns real interest, without any extra risk. Here’s why the difference matters.

Traditional savings accounts at large banks pay little to no interest, which means your money isn’t really working for you. As inflation and everyday costs rise, leaving your savings in a low-interest account quietly erodes its purchasing power. Most people keep their savings at the same bank as their checking account because it’s convenient, familiar, and “good enough.” I did the same for years, until I realized there was a better option: a High-Yield Savings Account (HYSA).

Using a HYSA could earn you 8 to 10 times more interest than your current bank gives you. The national average for savings accounts is currently 0.40% APY, while many high-yield savings accounts offer rates around 3.5% (as of December 2025).

What is APY?

APY stands for Annual Percentage Yield. Simply put, it is the rate of return on the money you deposit over one year. It helps you understand how much your money will grow in the account over time, taking compound interest into account.

Compounding can significantly increase your total earnings and outperforms simple interest over time. Compound interest gives you a return on both your initial deposit and previous earnings, while simple interest only pays you based on your initial deposit.

At larger amounts, the difference between simple and compound interest becomes significant. (that’s exactly what we want). 

Finding the best HYSA

1. Look for accounts with the highest interest rates.

2. Check if there is an initial deposit requirement or minimum balance, ideally $0 for both.

3. Choose an account with no fees.

4. Determine if the bank is right for you. I prefer banks that are well-known, reliable, and have easy-to-use interfaces. If you already have another type of account or a credit card at a bank, opening your HYSA there can help keep everything in one place. Remember: APY isn’t the only factor that makes a good account.

Examples of HYSAs:

• Capital One - Capital One Online Performance Savings (Best Overall)

• Ally - Ally Online Savings Account

• SoFi - SoFi Savings Account

• Marcus - Marcus High Yield Savings (I use this one)

Is getting a HYSA difficult?

No, it’s really simple! Opening a HYSA only takes a few minutes and requires basic information such as your name, email address, and Social Security number. Most of the time, your account will be approved immediately.

Funding your HYSA

Your HYSA can be linked to other bank accounts. Start by connecting your checking account, you’ll just need your account and routing numbers. Once connected, you can set up automatic contributions to your HYSA at any frequency and amount you choose. This removes the manual work from saving and makes it easy to grow your account. Adjusting contributions later is quick and simple.

How to use a HYSA

A HYSA is a short-term savings vehicle, not a long-term investment, so it’s not meant for retirement or a vacation home you plan to buy in 20 years. It’s also important not to use it for regular withdrawals.

Your HYSA is best used for your emergency fund (3–6 months of living expenses) and other short- to mid-term goals, such as a new car, vacation fund, wedding fund, or down payment for a home. Avoid using a HYSA for paying monthly or weekly bills.

Pro Tip: Some banks allow you to open multiple HYSAs for free, and you can label each account for its intended purpose.

Things to know before opening

• Make sure your account is with an FDIC-insured bank to protect your money.

• HYSAs are online-only accounts. You won’t receive a debit card, and you won’t be using it for everyday transactions.

• Read the disclosures on fees, minimum balance requirements, and any initial deposit requirement.

Taxes on your HYSA earnings

Yes, all earnings in a HYSA are taxed as ordinary income. The bank will send you a tax form at the end of the year to report your earnings.

How I use my HYSA

I’ve been using my HYSA for years, starting with Marcus by Goldman Sachs. Marcus offers competitive rates, no minimums, and allows me to open multiple accounts at no cost.

When I had a consistent paycheck, I linked my HYSA to my direct deposit at my employer so a portion of each paycheck went automatically into my account. This allowed me to fund multiple savings goals without thinking about it. Now, with fluctuating monthly income, I deposit everything into my checking account first, then transfer to my HYSA manually. Do what works best for you, you can always adjust later.

I use my HYSA for my emergency fund, travel fund, tax savings, and a new car fund. As I develop new goals, I open separate HYSAs and fund them accordingly. Determining how much you need for each goal adds clarity and makes the process simple.

Sample Case: You want to buy a car for $12,000 in one year and get paid bi-weekly. Starting with $0, you can automatically contribute $500 every two weeks or $1,000 per month. Within 12 months, you’ll hit your goal, earn extra interest, and be glad you automated your savings. That’s the power of letting your money work for you!

Now you have all the information you need. It’s time to open your HYSA and start saving today!
