A good interest rate depends on what you're saving in and what the market is offering right now
There is no single "good" interest rate — it changes based on the type of account, the current economic environment, and what other banks are paying. A rate that was excellent two years ago might be below average today. What matters is comparing what you're being offered to what competitors are offering for the same product, right now, and understanding how that rate affects your money over time.
The Federal Reserve sets a benchmark rate that influences what banks pay on savings. When that rate is higher, banks typically offer higher rates on savings accounts, certificates of deposit (CDs), and money market accounts. When it's lower, so are the rates banks offer you. This means you should check rates frequently — what was competitive last month may not be this month.
Key Takeaways
- Compare rates across at least three banks for the same account type, because rates vary widely even when the Federal Reserve rate stays the same.
- High-yield savings accounts typically pay more than traditional savings accounts at the same bank, sometimes by 10 to 15 times as much.
- A CD locks your money away for a set period (three months to five years) in exchange for a may provide rate, which is useful only if that rate beats what a savings account offers.
- The real value of a rate depends on how long you keep money in the account — a 0.01% difference on $1,000 for one year costs you about $0.10, but on $100,000 it costs $10.
How to compare rates across account types
Start by deciding what type of account fits your goal. If you need the money within a year, a savings account or money market account makes sense because you can withdraw without penalty. If you won't touch the money for two to five years, a CD might offer a higher rate because the bank knows it can use your money for longer.
Once you've picked the account type, visit the websites of at least three banks — including online banks like Ally, Marcus, or Discover, which typically pay more than brick-and-mortar banks. Write down the rate each one offers, the minimum deposit required, and any fees. The rate alone doesn't tell the full story; a bank that charges a monthly maintenance fee or requires a $10,000 minimum deposit may not be the best choice even if the rate looks higher.
Check the Annual Percentage Yield (APY), not just the interest rate. APY includes the effect of compounding — how often the bank adds interest to your balance — so it's the true number that matters for your money.
Why high-yield savings accounts often beat regular savings accounts
A traditional savings account at a large bank might pay 0.01% APY. A high-yield savings account at an online bank might pay 4.00% to 5.00% APY. On $10,000, that difference means earning roughly $10 per year in the traditional account versus $400 to $500 in the high-yield account — the same money, the same bank rules, but a vastly different outcome.
High-yield accounts work the same way as regular savings accounts: your money is insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000, you can withdraw anytime without penalty, and there are no strings attached. The reason online banks pay more is that they have lower overhead costs — no physical branches to maintain — so they pass some of that savings to you.
The trade-off is convenience. You can't walk into a branch or call a local phone number. Most high-yield accounts are managed entirely online through a website or app. If you need to move money quickly or prefer in-person banking, that matters. But if you're saving money you won't need immediately, the rate difference is usually worth the slight inconvenience.
When a CD rate makes sense versus a savings account
A CD typically locks your money away for a fixed period — three months, six months, one year, two years, or five years. In exchange, the bank guarantees a set interest rate for that entire period. If you withdraw early, you pay a penalty, usually a few months' worth of interest.
A CD only makes sense if the rate is noticeably higher than what a high-yield savings account offers for the same timeframe. If a one-year CD pays 4.50% and a high-yield savings account pays 4.75%, the savings account is better because you keep your money accessible and earn more. But if the CD pays 5.25% and the savings account pays 4.75%, the extra 0.50% might be worth locking your money away — that's an extra $50 per year on $10,000.
CDs are useful when you know you won't need the money for a specific period and want to may provide a rate before rates fall. They're not useful if you might need the money early or if savings account rates are already competitive.
How inflation affects whether a rate is actually good
A 4.50% interest rate sounds good until you remember that inflation — the rate at which prices rise — affects your purchasing power. If inflation is running at 3.50% per year and you earn 4.50%, your money is only growing 1.00% faster than the cost of living. That's still a gain, but smaller than the headline rate suggests.
When inflation is high, even seemingly good rates may not keep pace. When inflation is low, a 2.00% rate might be genuinely strong. This is why comparing your rate to what other banks offer matters more than comparing it to a number you remember from years ago. The current market tells you whether you're being treated fairly.
What to do if rates drop after you open an account
If you lock money into a CD and rates drop, you're protected — your rate stays the same for the full term. If you're in a savings account and rates drop, your bank will lower your rate too, and there's nothing you can do about it except move your money to a bank offering a better rate.
If you're in a savings account and rates rise, you benefit immediately if your bank raises your rate. Some banks do this quickly; others lag. If your bank isn't raising your rate when competitors are, that's a signal to shop around and move your money. Banks count on inertia — the assumption that you won't bother switching — so they sometimes pay less to existing customers than to new ones.
Check your rate once or twice a year. If it's fallen significantly below what competitors offer, moving your money takes about 15 minutes and can earn you hundreds of dollars per year on a large balance.
The math: how much difference does a rate actually make
The impact of a rate depends on three things: how much money you have, how long you keep it there, and how much the rate differs from alternatives.
| Balance | Rate A (2.00%) | Rate B (4.50%) | Difference per year |
|---|---|---|---|
| $1,000 | $20 | $45 | $25 |
| $10,000 | $200 | $450 | $250 |
| $50,000 | $1,000 | $2,250 | $1,250 |
| $100,000 | $2,000 | $4,500 | $2,500 |
If you have $10,000 and the difference between two banks is 0.50%, you earn an extra $50 per year. That's not life-changing, but it's also not nothing — it's a free lunch if you're going to keep the money somewhere anyway. If you have $100,000, that same 0.50% difference is $500 per year. Over five years, that's $2,500 in extra earnings just from picking the right bank.
The longer your money sits, the more the rate matters. A 0.50% difference on $50,000 for one year costs you $250. For five years, it costs you roughly $1,250 (the math is slightly more complex because of compounding, but the principle holds). This is why shopping around takes so little time but pays so much.
Frequently Asked Questions
Is 4% a good interest rate right now?
It depends on the account type and when you're reading this. In 2024, 4% to 5% is typical for high-yield savings accounts, so 4% is on the lower end of competitive. For a CD, 4% might be below what's available. Check what three online banks are currently offering for the same account type — if 4% is in the middle of that range, it's reasonable; if it's below, look elsewhere.
Should I move my money if I find a better rate?
Yes, if the difference is meaningful to your balance. Moving $50,000 from a 2% account to a 4.5% account earns you an extra $1,250 per year. The transfer takes about a week and requires filling out a form. If you're keeping the money there for at least a year, the extra earnings almost always justify the small effort.
Do I lose money if I break a CD early?
You don't lose your principal, but you pay an early withdrawal penalty, usually three to six months of interest. If you withdraw from a one-year CD after six months and the penalty is three months of interest, you lose roughly half of what you would have earned. This is why CDs only make sense if you're confident you won't need the money before the term ends.
Why do online banks pay more than big banks?
Online banks have no physical branches, no tellers, and lower staff costs, so they pass some of those savings to customers through higher rates. They make money on the difference between what they pay you and what they charge borrowers for loans. Big banks have higher overhead and often prioritize other products, so they pay less on savings.
What if my bank stops paying interest on my account?
Banks can lower rates anytime, and they do when the Federal Reserve rate drops. You can't stop them, but you can move your money to a bank that's still paying competitively. This is why checking your rate once or twice a year matters — if it's fallen far behind, switching takes minutes and can save you hundreds per year.
