APY (Annual Percentage Yield)
The rate of interest your savings account pays over a year, including the effect of compounding. A higher APY means your money grows faster. See How Much Interest Can You Actually Earn on Savings? for real examples.
Budget
A plan that compares your income to your expenses so you know where your money is going, instead of finding out after the fact. See Budgeting for People Who Have Never Budgeted Before.
Checking Account
A bank account designed for frequent, everyday spending — bill payments, debit card purchases, and receiving your paycheck. See Checking vs. Savings Account.
Compound Interest
Interest calculated not just on your original deposit, but also on interest you've already earned. Over time, this means your money grows a bit faster than simple, flat-percentage math would suggest.
Debt Avalanche
A debt payoff method where you pay minimums on all debts and put any extra money toward the debt with the highest interest rate first. Usually saves the most money in total interest. See Emergency Fund vs. Paying Off Debt.
Debt Snowball
A debt payoff method where you pay minimums on all debts and put any extra money toward the smallest balance first, for quicker psychological wins.
Direct Deposit
An electronic payment, such as a paycheck, deposited automatically into your bank account rather than paid by paper check.
Emergency Fund
Money set aside specifically for unexpected, necessary, urgent costs — not your regular bills or spending money. See What Is an Emergency Fund and Why Beginners Need One.
FDIC Insurance
Federal Deposit Insurance Corporation coverage that protects deposits at insured banks up to a set limit per depositor, per bank, if the bank fails. Credit unions have equivalent coverage through the NCUA. Always confirm an institution is insured before opening an account.
Fixed Expense
A regular expense that stays roughly the same amount each month, like rent or a phone bill — as opposed to a variable expense.
High-Yield Savings Account (HYSA)
A savings account, often offered by an online-only bank, that pays a meaningfully higher APY than a typical savings account at a traditional bank. See What Is a High-Yield Savings Account?.
Income Buffer
A cushion of savings, separate from an emergency fund, used to smooth out unpredictably low-earning months — especially useful for irregular income. See How to Budget on an Irregular or Low Income.
Minimum Balance
The smallest amount of money a bank account must hold, in some cases, to avoid a fee or to earn the account's advertised interest rate.
Monthly Maintenance Fee
A fee some banks charge simply for holding an account, sometimes waived if you meet certain conditions like a minimum balance or direct deposit.
NCUA Insurance
National Credit Union Administration coverage that protects deposits at insured credit unions, similar to FDIC insurance for banks.
Net Income
The amount of money you actually take home after taxes and other deductions — as opposed to gross income, which is your pay before deductions. Budgets should generally be built around net income.
No-Spend Month
A time-limited challenge where you pause non-essential spending (not bills or essentials) for 30 days to reset spending habits and free up money for savings. See No-Spend Month: A Beginner's Step-by-Step Guide.
Overdraft Fee
A fee a bank charges when your checking account balance goes negative, typically because a payment or withdrawal exceeded your available balance.
Round-Up Savings
A savings feature offered by some banks and apps that rounds each debit card purchase up to the nearest dollar and automatically moves the difference into savings.
Savings Account
A bank account designed to hold money you're not spending right away, which usually earns some interest over time. See Savings Account Basics.
The 50/30/20 Rule
A simple budgeting method that splits after-tax income into roughly 50% needs, 30% wants, and 20% savings and debt payoff. See The Simplest Budgeting Method for Beginners.
Variable Expense
An expense that changes from month to month, like groceries or entertainment — as opposed to a fixed expense.
