Study these terms before or after solving the puzzle. Each definition includes a real-world US example.
CHECKING
A checking account is a bank deposit account designed for frequent, everyday transactions. It allows unlimited deposits and withdrawals through debit cards, checks, ATM access, and electronic transfers. Checking accounts typically pay little or no interest because they prioritize liquidity over yield. They are the central hub of personal financial management — where paychecks are deposited and bills are paid.
Chase Total Checking is one of the most popular checking accounts in the US, with over 60 million account holders. The account comes with a debit card, mobile check deposit, Zelle transfers, and access to 16,000 ATMs nationwide. Most Americans use their checking account as the foundation of their day-to-day financial life.
ROUTING
A routing number (also called an ABA routing number) is a 9-digit code assigned to financial institutions by the American Bankers Association. It identifies which bank or credit union holds an account and is used for electronic transactions including direct deposits, bill payments, ACH transfers, and wire transfers. Every bank has at least one routing number; large banks may have several based on region.
Wells Fargo has different routing numbers by state — for example, 121042882 in California and 121000248 in other western states. When your employer sets up direct deposit, they need your routing number (to find your bank) and account number (to find your specific account). This pair of numbers is printed on every paper check.
OVERDRAFT
An overdraft occurs when you spend more money than is available in your checking account, causing your balance to go negative. Banks typically handle overdrafts in two ways: declining the transaction (overdraft protection off) or covering it and charging a fee ($25–$35 per transaction). Overdraft protection can link your checking account to a savings account or credit card to automatically cover shortfalls. New regulations have significantly reduced overdraft fees at major banks.
Overdraft fees were historically a major profit center for banks — Americans paid $15 billion in overdraft fees in 2019. Following regulatory pressure and competition from fintech challengers like Chime, major banks dramatically reformed their policies. Bank of America reduced overdraft fees from $35 to $10, and Chase eliminated non-sufficient funds (NSF) fees entirely.
FDIC
The Federal Deposit Insurance Corporation (FDIC) is an independent US government agency that insures deposits at member banks and savings institutions. Created in 1933 after thousands of bank failures wiped out depositors' savings during the Great Depression, the FDIC insures up to $250,000 per depositor, per institution, per ownership category. FDIC insurance is free for depositors — banks pay the premiums.
When Silicon Valley Bank failed in March 2023 — the second-largest bank failure in US history — the FDIC stepped in immediately. All depositors were made whole, including those with balances above the $250,000 limit (through an emergency systemic risk exception). This swift action prevented a panic from spreading to other regional banks.
WIRE
A wire transfer is an electronic transfer of funds between banks, typically used for large or time-sensitive payments. Domestic wire transfers (within the US) usually complete the same business day; international wires may take 1–5 business days. Wire transfers are more secure and faster than ACH transfers but cost more — typically $15–$35 for outgoing domestic wires. They are commonly used in real estate closings, business transactions, and international payments.
When closing on a home purchase, buyers typically wire their down payment and closing costs to the title company. A $50,000 wire transfer might cost $25–$30 in fees but guarantees same-day settlement — critical in real estate transactions where timing is legally binding. Unlike checks, wire transfers are generally final and irreversible once sent.
ACH
ACH (Automated Clearing House) is an electronic network for processing batch financial transactions in the US. ACH transfers include direct deposits (payroll), bill payments, tax refunds, Social Security payments, and peer-to-peer transfers through apps like Venmo and Cash App. ACH transfers are slower than wire transfers (typically 1–3 business days) but usually free or very low cost — making them the backbone of everyday electronic payments.
The ACH network processes over 30 billion transactions per year worth nearly $80 trillion — including virtually every paycheck direct deposit in America. When you set up autopay for your mortgage, car payment, or utilities, you're authorizing ACH debits. The IRS uses ACH to send over 90% of tax refunds directly to bank accounts.
INTEREST
Bank interest is the amount paid to depositors for keeping money in a savings or money market account, or charged to borrowers for using credit. For depositors, interest is expressed as Annual Percentage Yield (APY), which includes the effect of compounding. Following the Fed's rate hikes of 2022–2023, high-yield savings accounts briefly offered 5%+ APY — the highest in 15 years — rewarding savers who moved cash from low-yield traditional banks.
A traditional big-bank savings account might offer 0.01% APY — earning $1/year on $10,000. A high-yield savings account at an online bank (like Marcus by Goldman Sachs or Ally) offered 5.00% APY in 2023 — earning $500/year on the same $10,000. This $499 difference illustrates why shopping for interest rates matters.
DEBIT
A debit card is linked directly to a checking account, allowing purchases and ATM withdrawals by immediately debiting (reducing) the account balance. Unlike credit cards, debit cards don't create debt — you can only spend what you have. They are protected by federal Regulation E, which limits consumer liability for unauthorized transactions (typically $50 if reported within 2 days). Most debit cards carry Visa or Mastercard branding and are accepted wherever credit cards are.
Debit cards processed 41 billion transactions worth $4.4 trillion in 2022 — making them the most used payment method in the US by volume. However, debit cards offer fewer consumer protections than credit cards in dispute resolution, and don't help build credit history. Financial advisors often recommend using credit cards (paid in full monthly) for purchases when possible.
DEPOSIT
A bank deposit is money placed into a bank account for safekeeping. Deposits can be made via cash, check, mobile deposit (photograph), ACH transfer, or wire transfer. Demand deposits (checking accounts) can be withdrawn anytime; time deposits (CDs — Certificates of Deposit) lock funds for a fixed period at a higher interest rate. The FDIC insures deposits at member banks up to $250,000.
Mobile deposit has transformed banking: Americans deposit over $1 trillion in checks via smartphone cameras each year, reducing branch visits dramatically. Bank of America reported that over 90% of deposits by check are now made through mobile or ATM rather than teller windows — fundamentally changing the economics of retail banking.
CREDIT
A credit union is a member-owned, nonprofit financial cooperative that provides banking services — checking accounts, savings, loans, and mortgages. Unlike for-profit banks, credit unions return profits to members through lower loan rates, higher savings yields, and reduced fees. Membership is typically based on employer, geographic area, or association affiliation. Credit unions are insured by the NCUA (equivalent to the FDIC).
Navy Federal Credit Union — the world's largest credit union with over 13 million members and $170 billion in assets — serves military personnel and their families. It consistently offers auto loan rates 1–2% below major banks and higher savings yields. Members who bank with credit unions typically save hundreds of dollars per year in fees and interest compared to commercial bank customers.
