A
Account Balance
The total amount of money currently in a bank account. It changes every time money is deposited or withdrawn.
Example: "After depositing my paycheck, my account balance went from $250 to $1,450."
Try it: Check your balance in the budget calculator or practice in CustomBank.
ACH (Automated Clearing House)
An electronic network used for processing financial transactions like direct deposits and bill payments between banks.
Example: "My employer pays me through ACH direct deposit every two weeks."
APR (Annual Percentage Rate)
The yearly interest rate charged on borrowed money (loans, credit cards) or earned on savings. Includes fees and other costs.
Example: "A credit card with 22% APR means you would pay about $220 per year in interest on a $1,000 balance."
APY (Annual Percentage Yield)
The actual rate of return you earn on a savings account or investment in one year, including the effect of compound interest.
Example: "My savings account earns 4.5% APY, so $1,000 would grow to about $1,045 in a year."
ATM (Automated Teller Machine)
A machine that lets you withdraw cash, check your balance, and make deposits using a debit card and PIN. Available 24/7.
Example: "I used the ATM at the grocery store to withdraw $60 for the weekend."
Automatic Transfer
A scheduled, recurring transfer of money between accounts. Often used to build savings or pay bills on time without manual action.
Example: "I set up an automatic transfer of $100 every payday from checking to savings."
Try it: Practice setting up transfers in CustomBank.
B
Bank Statement
A monthly document from your bank showing all transactions (deposits, withdrawals, fees) and your ending balance for that period.
Example: "I review my bank statement every month to make sure there are no charges I don't recognize."
Try it: Practice reading statements with our Bank Statement Reading Worksheet.
Budget
A plan for how you will spend and save your money over a period of time, usually monthly. Lists income and all expected expenses.
Example: "My monthly budget puts $1,200 toward rent, $400 toward groceries, and $200 toward savings."

Bounced Check
A check that a bank refuses to process because the account doesn't have enough money to cover it. Also called a "returned check" or "NSF check."
Example: "The rent check bounced because I forgot about the utility payment that cleared first."
C
Checking Account
A bank account designed for everyday transactions: paying bills, buying things with a debit card, and receiving deposits like paychecks.
Example: "I use my checking account for rent, groceries, and gas. My savings account is separate."
Try it: Practice managing checking accounts in CustomBank.
Compound Interest
Interest calculated on both the original amount and any interest already earned. Your money grows faster over time because you earn "interest on interest."
Example: "$1,000 at 5% compound interest becomes $1,050 after year one, $1,102.50 after year two (you earned interest on $1,050, not just $1,000)."
Credit Score
A number (300-850) that represents how reliable you are at paying back borrowed money. Higher scores make it easier to get loans and lower interest rates.
Example: "A credit score of 750 is considered 'good' and will qualify you for better loan rates."
Credit Union
A nonprofit financial institution owned by its members. Similar to a bank but often offers lower fees and better interest rates.
Example: "My credit union offers free checking with no minimum balance, unlike the big bank down the street."
D
Debit Card
A card linked to your checking account that lets you make purchases. The money comes directly out of your account immediately, unlike a credit card.
Example: "I paid for lunch with my debit card and the $12 was instantly deducted from my checking account."
Deposit
Adding money to your bank account. Can be done through direct deposit, ATM, mobile check deposit, or in person at a bank branch.
Example: "I deposited my birthday check for $100 using my bank's mobile app."
Try it: Practice making deposits in CustomBank.
Direct Deposit
Your paycheck or other regular payment is sent electronically straight to your bank account. No paper check needed.
Example: "With direct deposit, my paycheck hits my account every Friday morning automatically."
E
Emergency Fund
Money set aside in a savings account for unexpected expenses like car repairs, medical bills, or job loss. Experts recommend 3-6 months of expenses.
Example: "My emergency fund covered the $800 car repair so I didn't have to use a credit card."
Endorse
To sign the back of a check so it can be cashed or deposited. Required before a bank will process the check.
Example: "Don't forget to endorse your paycheck before depositing it at the ATM."

F
FDIC (Federal Deposit Insurance Corporation)
A government agency that insures bank deposits up to $250,000 per depositor. If your bank fails, the FDIC guarantees you get your money back.
Example: "I keep my savings in an FDIC-insured bank, so even if the bank went bankrupt, my money is protected."
Fee
A charge from the bank for a service or penalty. Common fees include monthly maintenance fees, overdraft fees, and ATM fees.
Example: "My bank charges a $3 fee if I use an ATM that isn't part of their network."
Fixed Expense
A regular cost that stays the same amount each month, like rent, a car payment, or a subscription. Easier to budget for than variable expenses.
Example: "Rent ($1,200) and my phone bill ($50) are fixed expenses. Groceries vary month to month."
I
Interest
Money a bank pays you for keeping your money in a savings account, or money you pay a bank for borrowing money (like a loan).
Example: "My savings account earns 4% interest, so my $5,000 earns about $200 a year."
Interest Rate
The percentage used to calculate interest. For savings, a higher rate means more earnings. For loans, a higher rate means more cost.
Example: "I chose the savings account with the highest interest rate: 4.5% versus 0.5% at my old bank."
L
Loan
Money borrowed from a bank that must be paid back with interest over a set period. Common types: auto loans, student loans, mortgages, personal loans.
Example: "I took out a $15,000 student loan at 5% interest with a 10-year repayment term."
M
Minimum Balance
The lowest amount of money a bank requires you to keep in your account to avoid fees or maintain the account.
Example: "My checking account requires a $500 minimum balance or I get charged a $12 monthly fee."
Mobile Banking
Using a smartphone app to manage your bank account: check balances, transfer money, deposit checks, and pay bills from anywhere.
Example: "I deposited my paycheck through mobile banking by taking a photo of the check."
Try it: CustomBank simulates a mobile banking app so you can learn the interface.
Monthly Statement
See Bank Statement.
N
Net Income
The amount of money you take home after taxes and other deductions are subtracted from your gross (total) pay. Also called "take-home pay."
Example: "My gross salary is $3,500/month, but my net income after taxes is $2,800."
Try it: Use your net income in the budget calculator to plan your spending.
NSF (Non-Sufficient Funds)
When your account doesn't have enough money to cover a transaction. The bank declines the payment and usually charges an NSF fee ($25-$35).
Example: "My $200 rent payment was declined for NSF because I only had $180 in my account."
O
Online Banking
Managing your bank account through a website on your computer. Similar to mobile banking but accessed through a browser rather than an app.
Example: "I pay my credit card bill through online banking every month."
Overdraft
When you spend more money than is in your account and the bank covers the difference. The bank then charges you an overdraft fee (typically $30-$35).
Example: "I had $50 in my account and bought $75 worth of groceries. The bank covered the $25 overdraft but charged me a $34 fee."
P
Payee
The person or company who receives a payment. On a check, the payee is the name written on the "Pay to the Order of" line.
Example: "When writing a rent check, my landlord is the payee."
Try it: Practice with our Check Writing Worksheet.
PIN (Personal Identification Number)
A secret 4-digit code used to access your bank account at ATMs and authorize debit card purchases. Never share your PIN with anyone.
Example: "I chose a PIN that isn't my birthday or any number someone could guess."
Principal
The original amount of money deposited or borrowed, before any interest is added. Interest is calculated based on the principal.
Example: "I borrowed $10,000 (the principal). Over 5 years at 6% interest, I'll pay back $11,600 total."
R
Receipt
A record of a completed transaction showing the date, amount, and what was purchased or paid. Important for tracking spending and returns.
Example: "I saved my ATM receipt to confirm the $200 deposit went through."
Routing Number
A 9-digit number that identifies your bank. Used for setting up direct deposits, wire transfers, and automatic payments. Found on checks and in your banking app.
Example: "My employer asked for my routing number and account number to set up direct deposit."
S
Savings Account
A bank account designed for storing money you don't need right away. Earns interest over time. Not meant for everyday spending.
Example: "I keep my emergency fund in a savings account where it earns 4% interest."
Try it: Practice managing savings in CustomBank.
Simple Interest
Interest calculated only on the original amount (principal), not on any previously earned interest. The simpler form of interest calculation.
Example: "$1,000 at 5% simple interest earns exactly $50 per year, every year."
Statement
See Bank Statement.
T
Transaction
Any activity that moves money in or out of your account: deposits, withdrawals, purchases, transfers, and fee charges.
Example: "My bank statement shows 47 transactions this month, including 12 deposits and 35 purchases."
Transfer
Moving money from one account to another, either within the same bank or between different banks.
Example: "I transferred $500 from my checking account to my savings account."
Try it: Practice transferring money between accounts in CustomBank.
V
Variable Expense
A cost that changes from month to month, like groceries, gas, entertainment, or clothing. Harder to predict than fixed expenses.
Example: "I spent $350 on groceries last month but only $280 this month. That's why groceries are a variable expense."
W
Withdrawal
Taking money out of your bank account. Can be done at an ATM, bank branch, or through electronic transfers.
Example: "I made a $60 ATM withdrawal for spending cash this weekend."
Try it: Practice withdrawals in CustomBank.
Wire Transfer
An electronic transfer of money between banks, often used for large amounts or international payments. Usually processed the same day but may have fees ($15-$50).
Example: "I used a wire transfer to send the $5,000 down payment to the real estate company."
Y
Yield
The income earned from an investment or savings account, expressed as a percentage. See also APY.
Example: "The high-yield savings account offers 4.5% — much better than the 0.5% from a regular account."
