The services banks provide fall into a handful of categories you’ll use at different points in your life: holding your money in insured accounts, lending it back to you when you need more, moving funds between people and businesses, storing valuables, and helping you invest for the future. Most U.S. banks are federally insured, which means your deposits are protected up to $250,000 per depositor, per bank, for each ownership category.1FDIC. Understanding Deposit Insurance What follows is a plain walk through what each service actually does and the rules that govern it.
Holding Your Money
The core job of a bank is to keep your cash safe and accessible. A checking account handles everyday spending through debit cards, checks, and electronic transfers. Federal rules require banks to make deposits available on a set schedule; cash deposited in person, for instance, must be available by the next business day.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC)
Savings accounts pay interest while keeping funds accessible. The Federal Reserve historically capped certain savings withdrawals at six per month but removed that limit in 2020.3Federal Register. Regulation D: Reserve Requirements of Depository Institutions Some banks still set their own transfer limits, so read your account agreement. High-yield savings accounts, mostly from online banks, paid around 4% APY in early 2026, well above what most traditional banks offered.
Money market accounts sit between checking and savings, usually paying more interest but requiring a larger minimum balance to avoid monthly fees. Certificates of deposit lock your money for a fixed term in exchange for a guaranteed rate. The bank has to disclose the maturity date and the penalty for pulling money out early, which commonly equals several months of earned interest.4eCFR. 12 CFR Part 1030 – Truth in Savings (Regulation DD)
One account cost to watch for is the overdraft fee, charged when the bank covers a transaction that exceeds your balance. These historically ran $30 to $36 at the largest banks. Capital One, Citibank, and Ally Bank have dropped them entirely, and others now waive the fee if you’re overdrawn by $50 or less. You can also ask to opt out of overdraft coverage altogether.
How Your Deposits Are Insured
FDIC insurance covers each depositor up to $250,000 per bank, per ownership category. If the bank fails, you get your money back dollar for dollar, including interest posted through the closing date.1FDIC. Understanding Deposit Insurance Credit unions provide equivalent protection through the National Credit Union Share Insurance Fund at the same $250,000 limit per member.5MyCreditUnion.gov. Share Insurance
You can hold far more than $250,000 at one bank by using different ownership categories, each insured separately:
- Single accounts: each person gets $250,000 of coverage on individually owned accounts.
- Joint accounts: each co-owner’s share across all joint accounts is insured up to $250,000.6FDIC. Joint Accounts
- Trust accounts: $250,000 per owner per eligible beneficiary, up to $1,250,000.
- Retirement accounts: IRAs and certain other retirement accounts get their own $250,000 of coverage per person.
A couple with three children, stacking all four categories, could qualify for up to $3,500,000 in coverage at a single bank.7FDIC. Your Insured Deposits Important boundary: FDIC insurance covers deposit accounts only. Anything stored in a safe deposit box, including cash, is not insured.8FDIC. Five Things to Know About Safe Deposit Boxes, Home Safes and Your Valuables
Borrowing From a Bank
Banks lend through several products, each built around a different purpose. For every one of them, the bank must disclose your annual percentage rate and the total cost of borrowing before you sign.9Federal Trade Commission. Truth in Lending Act
- Mortgages are long-term home loans, usually 15 or 30 years, with the property as collateral. Stop paying and the bank can foreclose.
- Auto loans run three to seven years and are secured by the vehicle.
- Personal loans are unsecured and can cover almost any purpose, but interest rates tend to be higher because there’s no collateral.
- Credit cards are revolving lines you can borrow against, repay, and borrow against again. Federal law caps certain fees and requires your statement to show how long payoff would take if you made only minimum payments.9Federal Trade Commission. Truth in Lending Act
- Commercial loans finance businesses, often secured by equipment or receivables, and frequently include covenants the borrower has to maintain or risk default.
What Lenders Look At
For a conventional mortgage, lenders typically require a minimum credit score of 620 for a fixed-rate loan and 640 for an adjustable-rate mortgage.10Fannie Mae. General Requirements for Credit Scores Your debt-to-income ratio matters just as much. Fannie Mae’s standard threshold is 36% of stable monthly income for manually underwritten loans, with borrowers who have stronger credit and reserves qualifying up to 45%, and automated underwriting sometimes approving as high as 50%.11Fannie Mae. Debt-to-Income Ratios FHA, VA, and USDA loans have their own rules, but 620 is generally the credit-score floor for those as well.
Moving Money
How you move money depends on how fast it needs to arrive and what you’re willing to pay.
Wire Transfers
Wire transfers are the standard for large or time-sensitive payments. Domestic wires go through the Fedwire system, a Federal Reserve service that settles in real time; once processed, the transfer is final and irrevocable.12Board of Governors of the Federal Reserve System. Fedwire Funds Services International wires generally route through SWIFT. Expect roughly $25 to $30 for a domestic outgoing wire and $35 to $50 for an international one. Incoming wires are usually cheaper or free.
ACH Transfers
Automated Clearing House transfers power direct deposits, recurring bill payments, and most bank-to-bank transfers. They’re far cheaper than wires, often free for consumers. Same-day ACH now settles multiple times per business day and handles individual payments up to $1 million.13Nacha. Same Day ACH
Person-to-Person Payments
Most banks offer app-based person-to-person transfers, with Zelle the most common. Daily sending limits run from about $500 to $15,000 depending on the bank and account type, and monthly caps, where they exist, typically fall between $3,500 and $20,000.
Cashier’s Checks, Money Orders, and Business Services
Banks issue cashier’s checks and money orders, which are backed by the bank itself rather than your personal balance and are often required for real estate closings and other large transactions. On the business side, merchant services let companies accept card payments, and treasury management helps larger businesses consolidate cash across accounts and automate internal transfers.
Banking From Your Phone
Digital banking now covers most of what you used to need a teller for. Through a mobile app or your bank’s website, you can typically deposit a check by taking a photo of it, pay bills, set up automatic transfers, freeze a lost debit card instantly, and get real-time alerts for transactions above a threshold you choose. Some banks add budgeting tools that categorize spending and flag unusual activity.
Investing and Saving for Retirement
Many banks offer brokerage accounts for buying and selling stocks, bonds, mutual funds, and other securities. These accounts are regulated by FINRA, not the FDIC, so investments are not insured against market losses.14FINRA. Brokerage and Advisory Accounts: Factors to Consider When Choosing an Account Type
Banks also offer traditional and Roth individual retirement accounts. For 2026, you can contribute up to $7,500, or $8,600 if you’re 50 or older (the $7,500 base plus a $1,100 catch-up contribution).15Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Traditional IRA contributions may be tax-deductible now; qualified Roth withdrawals in retirement are generally tax-free. Which makes more sense depends on whether you expect to be in a higher or lower tax bracket when you retire.
Beyond retirement accounts, banks can serve as trustees, managing assets for beneficiaries under a fiduciary duty to put those beneficiaries’ interests first. Trust administration fees typically run 1% to 2% of trust assets per year. Bank financial advisors provide investment guidance and must disclose any conflicts of interest, such as higher commissions on specific products, under the Investment Advisers Act.16U.S. Securities and Exchange Commission. Staff Bulletin: Standards of Conduct for Broker-Dealers and Investment Advisers Conflicts of Interest Wealth management departments coordinate tax, estate, and investment planning for clients with larger portfolios.
Your Rights When Something Goes Wrong
Federal law protects you when something goes wrong with an electronic transaction, and how much you can lose depends heavily on how fast you act.
Lost or Stolen Debit Cards
If your debit card is lost or stolen, your liability tracks the reporting timeline:17Consumer Financial Protection Bureau. 1005.6 Liability of Consumer for Unauthorized Transfers
- Reported within two business days: maximum loss of $50.
- Reported after two business days but within 60 days of your statement: maximum loss of $500.
- Reported more than 60 days after your statement: you can be liable for the full amount of unauthorized charges that occur after that 60-day window.
Report a missing card immediately. If something outside your control, such as hospitalization or extended travel, caused the delay, the bank must extend these deadlines to a reasonable period.
Fixing Errors on Your Account
When you spot a mistake, a duplicate charge, a wrong amount, or a transfer you didn’t authorize, you have 60 days from the date the bank sent the statement to report it. The bank then has 10 business days to investigate. It can take up to 45 days if it needs more time, but only if it provisionally credits your account within those first 10 days so you aren’t left short.18eCFR. 12 CFR 205.11 – Procedures for Resolving Errors For international transactions or point-of-sale debit card disputes, the investigation window extends to 90 days.
Large Cash Deposits and Reporting
Any cash deposit or withdrawal over $10,000 in a single business day generates a Currency Transaction Report filed with the Treasury Department’s Financial Crimes Enforcement Network.19Financial Crimes Enforcement Network. The Bank Secrecy Act This is routine paperwork and doesn’t suggest anything is wrong.
What does raise flags is “structuring,” which means deliberately breaking a large transaction into smaller pieces to stay under the $10,000 threshold. Banks are trained to spot it, and it can trigger a Suspicious Activity Report even when the underlying money is legitimate.20eCFR. 12 CFR 208.62 – Suspicious Activity Reports If you need to deposit $15,000 in cash, deposit it in one trip.
Other Services Worth Knowing About
Banks rent safe deposit boxes for storing valuables like original deeds, birth certificates, or jewelry. Annual fees run from about $10 to $50 for small boxes and over $100 for larger ones. Remember that contents are not covered by FDIC insurance; if you want protection for what’s inside, you’ll need a rider on your homeowner’s or renter’s policy.8FDIC. Five Things to Know About Safe Deposit Boxes, Home Safes and Your Valuables
Most banks also provide notary services, often free for account holders, and some offer Medallion signature guarantees for securities transfers. A Medallion stamp is more than a notarization: it confirms your identity and authority to transfer securities, and the bank takes on financial liability if the guarantee turns out to be fraudulent.21SEC. Medallion Signature Guarantees: Preventing Unauthorized Transfers of Securities Banks also exchange foreign currency for travelers, with a markup over the wholesale rate; ordering ahead through your bank usually gets you a better rate than an airport kiosk.
Opening an Account
Under the USA PATRIOT Act, a bank has to verify your identity before opening an account. You’ll be asked for your full legal name, physical address, date of birth, and taxpayer identification number (usually your Social Security number).22Financial Crimes Enforcement Network. Interagency Interpretive Guidance on Customer Identification Program Requirements Under Section 326 of the USA PATRIOT Act Bring a government-issued photo ID such as a driver’s license or passport. Some banks ask for a second form of ID. For a trust account, the bank uses the trust’s employer identification number instead of a personal SSN.
