If your savings are sitting in a traditional bank savings account, there’s a good chance you’re earning close to nothing on them.
The national average interest rate on a traditional savings account sits around 0.45% APY. At that rate, $10,000 saved earns about $45 in a year.
A high-yield savings account at an online bank currently offers 4–5% APY on the same balance. That same $10,000 earns $400–$500 in a year — roughly 10 times as much — with zero additional effort.
The only thing standing between most people and that difference is not knowing it exists, or assuming it’s complicated to set up. Neither is true. This guide explains exactly how high-yield savings accounts work and how to choose one.
What Is a High-Yield Savings Account?
A high-yield savings account (HYSA) is a savings account that pays a significantly higher interest rate than the national average. They work identically to a regular savings account — you deposit money, it earns interest, it’s FDIC insured, and you can withdraw it when needed.
The difference is purely the interest rate.
High-yield savings accounts are almost exclusively offered by online banks — financial institutions that operate without physical branch locations. Because they don’t pay for physical branches, ATMs, and large local staff, they pass the cost savings to customers in the form of higher interest rates.
Traditional banks like Chase, Bank of America, and Wells Fargo offer savings accounts with APYs as low as 0.01%. Online banks like Ally, Marcus by Goldman Sachs, and SoFi regularly offer 4–5% APY on the same type of account.
How Interest Works in a High-Yield Savings Account
Interest in a savings account is expressed as APY — Annual Percentage Yield. APY accounts for compound interest, meaning interest is calculated not just on your original deposit but on previously earned interest as well.
Simple example:
$5,000 deposited at 4.5% APY:
The compounding effect grows over time. The longer money sits in a high-yield account, the more meaningful the interest becomes — especially for emergency funds and sinking funds that aren’t touched for extended periods.
What to Look for in a High-Yield Savings Account
Not all HYSAs are equal. Here’s what to evaluate before opening one:
APY (Interest Rate)
This is the primary factor. Compare current rates across multiple banks before deciding. Rates fluctuate with the federal funds rate — when the Fed raises rates, HYSA rates typically rise; when the Fed cuts rates, they fall. Check current rates at NerdWallet or Bankrate for up-to-date comparisons rather than relying on any single source.
No Monthly Fees
A monthly maintenance fee can easily wipe out your interest earnings. Look for accounts with zero monthly fees and no minimum balance requirement to waive them.
No Minimum Balance Requirement
Some accounts require a minimum deposit to open or maintain. Avoid accounts with requirements you can’t comfortably meet from day one.
FDIC Insurance
All legitimate US banks offer FDIC insurance up to $250,000 per depositor, per bank. Verify FDIC status before opening any account — you can check at fdic.gov.
Transfer Speed
Online-only banks typically take 1–3 business days to transfer money to and from your linked checking account. For an emergency fund, this is fine. For a primary spending account, it would be too slow. Know the transfer timeline before you need money in an emergency.
Mobile App and Ease of Access
Since you’ll manage this account entirely online, the bank’s app and website need to work well. Read user reviews before committing.
The Best High-Yield Savings Accounts (What to Look For in 2025)
Rather than recommending specific accounts (rates and terms change frequently), here are the institutions consistently known for competitive HYSA offerings. Always verify current rates before opening:
Ally Bank — No minimum balance, no monthly fees, consistently competitive rates, strong mobile app. One of the most popular choices for emergency funds.
Marcus by Goldman Sachs — No fees, no minimum, historically strong rates, clean interface. Good for straightforward savings without extras.
SoFi — Offers higher rates for members who set up direct deposit. Also provides checking and savings in one account, which some people find convenient.
American Express High Yield Savings — Competitive rates, no fees, backed by a well-known institution. No checking account option, which keeps it purely savings-focused.
Discover Online Savings — No fees, no minimum, reliable rates, and Discover’s customer service reputation is strong.
Compare current APYs across these at NerdWallet or Bankrate before deciding; the rankings shift as rates change.

Common Questions About High-Yield Savings Accounts
Are they safe?
Yes. FDIC-insured accounts are protected up to $250,000 per depositor per bank. Your money is as safe in an online high-yield savings account as in any traditional bank.
Do rates stay fixed?
No. HYSA rates are variable — they change with the federal funds rate. When you open an account, the rate is not locked in. It can go up or down over time.
Is there a limit on withdrawals?
Federal regulations previously limited savings account withdrawals to 6 per month. That limit was officially removed in 2020, though some banks still enforce their own limits. Check the specific account terms.
Can I have more than one?
Yes. Many people keep multiple high-yield savings accounts for different goals — one labeled “Emergency Fund,” one labeled “Vacation,” one labeled “Car Fund.” This makes it easy to track progress toward each goal without commingling funds.
Will I owe taxes on the interest?
Yes. Interest earned in a savings account is considered taxable income and must be reported on your federal tax return. Your bank will send a 1099-INT form for any year you earn $10 or more in interest.
How to Open a High-Yield Savings Account
The process takes 5–10 minutes:
- Choose a bank based on the criteria above
- Visit the bank’s website and click “Open an Account”
- Provide your personal information (name, address, Social Security number, date of birth)
- Link your existing checking account for transfers
- Make an initial deposit (many accounts have no minimum — even $1 to open)
- Confirm account via email
Most accounts are fully functional within one business day of opening.
Conclusion
A high-yield savings account is one of the simplest, most impactful personal finance moves available. No complexity, no risk, no fees, just a significantly better return on money you already have sitting in savings.
If your emergency fund, sinking funds, or short-term savings goals are sitting in a traditional bank savings account earning 0.01–0.45%, moving them takes less than 10 minutes and earns 10 times more interest immediately.
There’s no good reason to leave money in a low-yield account once you know the alternative exists.
