Yes, savings accounts do accrue interest. Every savings account at a federally insured bank or credit union earns interest on your deposited balance, though how much you actually pocket depends on the account’s annual percentage yield (APY), how often the bank compounds that interest, your balance, and any fees skimming off the top. The national average APY on savings accounts sits around 0.39% as of early 2026, while high-yield savings accounts at online banks are paying 4% to 5%.
How the Interest Is Calculated
Banks pay you interest because they lend out and invest your deposits. Two numbers describe that payment, and they are not the same. The interest rate is the simple annual rate applied to your balance. The APY is the number that matters, because it reflects your total return after compounding.
Compounding is where a savings account quietly does work for you. When a bank compounds interest daily, it calculates a small amount of interest on your balance each day and adds it to the balance before calculating the next day’s interest. You start earning interest on yesterday’s interest. Over a year, that snowball pushes the APY slightly above the stated interest rate on any account that compounds more than once a year.1Consumer Financial Protection Bureau. 12 CFR Part 1030 – Appendix A to Part 1030 Annual Percentage Yield Calculation
Most banks compound daily but only credit interest to your account monthly or quarterly. Between crediting dates, interest accrues in the background but hasn’t been deposited yet. Once it’s credited, your principal is a little higher, so the next cycle generates a slightly larger payment. The dollar difference between daily and monthly compounding is small on a typical balance, but it stacks up over years.
How the Bank Figures Your Balance
Two common methods are in use. The daily balance method applies the daily rate to whatever your full balance is on each individual day, so a Wednesday deposit starts earning interest on Wednesday. The average daily balance method adds up your balance for every day in the statement period, divides by the number of days, and applies the rate to that average. Results come out close if your balance stays stable. The daily balance method rewards mid-cycle deposits a bit faster.
Federal law requires banks to disclose the APY, the compounding frequency, and the crediting frequency before you open an account, and to flag any variable rate and how it can change.2eCFR. 12 CFR Part 1030 – Truth in Savings (Regulation DD) APY is the one figure that lets you compare accounts across banks on equal footing.
What Makes One Account Pay More Than Another
The biggest driver of savings rates is Federal Reserve policy. When the Fed raises its benchmark rate, banks generally lift APYs on savings accounts. When the Fed cuts, APYs usually drop. Savings account rates are variable, meaning the bank can change your APY at any time without advance notice. There is no lock-in like you’d get with a certificate of deposit.
The type of bank matters almost as much as the rate environment. Traditional banks carry branch overhead and tend to pass those costs through as lower rates. Online-only banks run leaner and consistently offer APYs several times higher than the national average. A large brick-and-mortar bank might advertise 0.01% APY while an online competitor pays 4% or more on the same type of account.
Tiered Rates
Some banks use tiered structures where the APY rises as your balance crosses thresholds. A bank might pay 0.05% on balances up to $25,000, then 1.00% between $25,000 and $100,000. Tiered accounts can carry conditions: minimum daily balances, monthly transaction minimums, or similar strings. Check those before chasing a top-tier rate you can’t consistently qualify for.
Your Balance
A larger balance earns more interest in dollars at any given APY. At 4%, $1,000 earns about $40 a year; $50,000 earns roughly $2,000. The practical upshot is that the gap between a bad rate and a good one costs you more as your balance grows. On $500, the difference between 0.01% and 4% APY is about $20 a year. On $50,000, that same gap is nearly $2,000.
Fees That Eat Into Your Interest
Interest means nothing if fees cancel it out. The common culprit is a monthly maintenance fee, typically $5 to $15 at banks that charge one. If your account earns $8 a month in interest but the bank charges $12 in maintenance, you’re down $4 a month for the privilege of keeping the account open. Compare the APY against the full fee schedule, not just the headline rate.
Paper statement fees are another quiet drain, usually $1 to $5 a month, and switching to electronic statements eliminates them at nearly every institution. Some banks also charge $5 to $15 for excess withdrawals over their internal limit. Many online banks have dropped maintenance fees and minimum balance requirements entirely, which widens their effective-return advantage over traditional banks beyond the rate difference alone. When evaluating any account, subtract every recurring fee from the projected annual interest to see your real return.
Withdrawals and Deposit Insurance
A quick note on two things people often lump in with “how savings accounts work.” The federal six-per-month withdrawal cap under Regulation D was suspended in April 2020 and that change is not temporary, but many traditional banks still enforce the old limit on their own and may charge excess transaction fees, convert the account, or close it for repeat violations. And your deposits at an FDIC-insured bank are protected up to $250,000 per depositor, per ownership category, with equivalent coverage at credit unions through the NCUA Share Insurance Fund.3Federal Deposit Insurance Corporation.

Taxes on the Interest You Earn
Interest earned on a savings account is ordinary income to the IRS. You owe federal income tax on it in the year the bank credits it, whether or not you withdraw the money. Credit union “dividends” on share savings accounts are treated the same way despite the different name.5Internal Revenue Service. Publication 17 (2025), Your Federal Income Tax
If you earn $10 or more in interest in a calendar year, the bank sends you Form 1099-INT and files a copy with the IRS.6Internal Revenue Service. About Form 1099-INT Interest Income Below $10, no form shows up, but you still owe the tax. The $10 threshold only triggers the bank’s paperwork; the IRS requires you to report all interest income regardless of amount and regardless of whether you received a form.7Internal Revenue Service. Topic No. 403, Interest Received Most states with an income tax tax interest income too, so check your state’s rules alongside the federal ones.
