What savings interest rates are and how they're set

A savings interest rate is the percentage of your account balance that a bank or credit union pays you each year for keeping money with them. If you have $1,000 in a savings account earning 4.5% APY, the bank will add roughly $45 to your account over twelve months (the exact amount depends on how often interest compounds, which varies by institution).

Banks set their own rates based on what the Federal Reserve does with its benchmark rate. When the Fed raises rates, banks typically raise what they pay on savings accounts within weeks or months. When the Fed cuts rates, banks usually lower savings rates faster than they raise them. This means your rate can change without warning, even if you do nothing.

The rate you see advertised is not may provide to stay the same. Banks can lower it at any time, though they must notify you before the change takes effect. Some accounts lock in a rate for a set period (like a certificate of deposit), but most savings accounts have variable rates that move with market conditions.

Key Takeaways

  • Savings rates vary widely by bank and account type, ranging from nearly 0% at some traditional banks to over 5% at online banks and credit unions.
  • The Federal Reserve's benchmark rate drives all savings rates upward or downward, but banks move at different speeds and by different amounts.
  • Online banks typically pay higher rates than brick-and-mortar banks because they have lower operating costs.
  • Your rate can change without your permission, so checking your account terms and shopping around every few months helps you keep more money.
  • Certificates of deposit (CDs) lock in a fixed rate for a specific time period, while money market accounts and high-yield savings accounts have variable rates.

Where rates differ most: online banks versus traditional banks

Online banks and credit unions almost always pay more on savings than traditional brick-and-mortar banks. A large national bank might pay 0.01% APY on a basic savings account, while an online bank pays 4.5% or higher on the same type of account. The difference comes down to overhead: online banks have no physical branches, fewer employees, and lower rent, so they pass those savings to customers through higher rates.

Credit unions, which are member-owned cooperatives rather than for-profit corporations, also tend to pay competitive rates. Some credit unions pay as much as online banks; others pay less. The rate depends on the individual credit union's size, membership, and lending activity.

Traditional banks justify lower rates by pointing to branch access, customer service, and brand recognition. If you value being able to walk into a physical location or speak to someone in person, you may accept a lower rate. If you're comfortable managing your account online and by phone, an online bank or credit union usually makes more financial sense.

How different account types affect your rate

Not all savings accounts pay the same rate, even at the same bank. High-yield savings accounts pay significantly more than regular savings accounts—sometimes 10 to 20 times as much. Money market accounts typically fall between regular savings and high-yield savings in terms of rate, though they often come with check-writing privileges and a debit card.

Certificates of deposit (CDs) lock in a fixed rate for a set term—usually three months to five years. Because you agree not to touch the money for that period, banks pay more on CDs than on savings accounts. A one-year CD might pay 5.0% while a high-yield savings account at the same bank pays 4.5%. If you withdraw money from a CD before the term ends, you pay an early withdrawal penalty that can erase months of interest.

Money market accounts require a higher minimum balance than savings accounts, sometimes $2,500 or more. In exchange, they pay a higher rate and may offer limited check-writing or debit card access. Some money market accounts have tiered rates: you earn more if your balance is higher.

Why your rate might drop even if the Fed doesn't cut

Banks can lower your savings rate whenever they want, as long as they give you notice first (usually 30 days). This happens most often when the Fed stops raising rates or when a bank decides it has enough deposits and doesn't need to attract new customers anymore.

If you opened a high-yield savings account at 5.0% six months ago, that rate may have already dropped to 4.75% or 4.5% without any change in Fed policy. Banks compete aggressively for deposits when rates are rising, but once they have enough money, they reduce rates to improve their profit margins. This is why checking your rate periodically and comparing it to what other banks offer matters: you may be earning significantly less than you could elsewhere.

The only way to lock in a rate is to open a CD. Once the CD term begins, the bank cannot lower your rate, no matter what happens in the market. The tradeoff is that you cannot access the money without paying a penalty.

How to compare rates across banks

The easiest way to compare is to visit bank websites directly and note the APY for each account type. Most banks display rates prominently on their savings or deposit pages. Write down the rate, the minimum balance required, and any fees (some banks charge monthly maintenance fees that eat into your earnings).

Websites like Bankrate, DepositAccounts, and the FDIC's BankFind tool let you filter banks by rate, account type, and location. These sites update rates regularly, though not always in real time, so always confirm the current rate on the bank's own website before opening an account.

When comparing, look at the APY, not just the interest rate. APY accounts for how often interest compounds (daily, monthly, or quarterly), so it shows you the true annual return. Two banks might advertise different rates, but if one compounds daily and the other compounds quarterly, the daily-compounding account will earn more.

What happens to your rate when the Fed changes policy

When the Federal Reserve raises its benchmark rate, banks typically raise savings rates within one to four weeks. The increase is usually smaller than the Fed's increase, and it varies by bank. A 0.25% Fed rate hike might result in a 0.20% increase to your savings rate at one bank and a 0.10% increase at another.

When the Fed cuts rates, banks lower savings rates much faster—sometimes within days. This asymmetry means your rate rises slowly but falls quickly. Over time, this pattern erodes your earnings if you stay with the same bank through multiple rate cycles.

You can track Fed policy through the Federal Reserve's website or financial news sites. The Fed meets eight times per year to decide on rate policy, and these meetings are announced in advance. If you expect the Fed to cut rates soon, locking in a CD rate now protects you from future drops.

Frequently Asked Questions

Can I move my money to a higher-rate account without losing interest?

Yes. You can withdraw money from one account and deposit it into another at any time without penalty (unless it's a CD before the term ends). The interest you've already earned stays with you. Some people move money between banks every few months to chase the highest available rates, though this requires more active management.

What's the difference between APY and interest rate?

Interest rate is the percentage the bank pays, but APY (annual percentage yield) includes the effect of compounding—how often interest is added back to your account and earns interest itself. APY is always equal to or higher than the stated interest rate. Always compare APYs, not interest rates, to see which account truly earns more.

Is my money safe if I move it to an online bank for a higher rate?

Yes, as long as the bank is FDIC-insured (most are). FDIC insurance protects up to $250,000 per account type per person at each bank, regardless of whether it's online or has physical branches. Check the bank's website or the FDIC's BankFind tool to confirm it's insured before opening an account.

Do I have to keep a minimum balance to earn the advertised rate?

Most high-yield savings accounts do not require a minimum balance to earn the full rate, but some do. Money market accounts and CDs often require minimums of $500 to $2,500. Read the account terms carefully, because if your balance falls below the minimum, the bank may lower your rate or charge a fee.

What happens to my rate if I don't touch my account for years?

Your rate can drop at any time, even if you never withdraw money. Banks notify you before lowering rates, but you have to read those notices or check your account regularly to know it happened. If you want a may provide rate for years, open a CD with a term that matches how long you plan to leave the money untouched.
