Budgeting & Cash Flow
Budget
A budget is a plan for how you expect to use your income during a specific period—usually one month.
Example: If you expect to receive $5,000 this month, your budget shows how much you plan to spend on housing, food, transportation, savings, debt payments and other expenses.
Why it matters: A budget helps you decide where your money should go before it disappears into unplanned spending.

Cash Flow
Cash flow describes when money enters and leaves your accounts.
Example: You may earn enough during the month to cover all your expenses but still run short if several bills are due before your next paycheck arrives.
Why it matters: A budget shows the overall plan. Cash-flow planning helps make sure the money is available on the day you need it.
Due Date
A due date is the date by which a bill or payment must be received.
Why it matters: Missing a due date can result in late fees, interest charges, service interruptions or damage to your credit.
Expense
An expense is money you spend or owe.
Expenses can include bills, groceries, transportation, subscriptions, entertainment, savings contributions and debt payments.
Fixed Expense
A fixed expense normally stays the same from month to month.
Examples: Rent, mortgage payments, car payments and certain insurance premiums.
Why it matters: Fixed expenses are usually easier to predict and should be included in your plan before flexible spending.
Income
Income is money you receive from sources such as wages, Social Security, pensions, investment distributions, rental income or a business.
Why it matters: Knowing the amount and timing of your income gives you the starting point for building a realistic financial plan.
Net Income
Net income—sometimes called take-home pay—is the amount you receive after taxes, insurance premiums, retirement contributions and other payroll deductions.
Example: Your gross paycheck may be $3,000, but the amount deposited into your checking account could be $2,250.
Why it matters: Your budget should generally use the amount you actually receive, not your gross salary.
Recurring Payment
A recurring payment happens on a regular schedule.
Examples: A monthly mortgage payment, weekly daycare payment or annual insurance premium.
Why it matters: Including recurring payments in your forecast helps prevent predictable expenses from becoming surprises.
Variable Expense
A variable expense can change from one month to the next.
Examples: Groceries, gasoline, electricity, dining out and entertainment.
Why it matters: Variable expenses provide more room for adjustment when you need to reduce spending.

Payment Schedules
Annual
Annual means once per year.
Examples: Property taxes, membership renewals and certain insurance premiums.
Why it matters: Annual expenses can be easy to overlook because they do not appear every month.
Biweekly
Biweekly means once every two weeks, resulting in 26 payments or paychecks during most years.
If you are paid biweekly, two months of the year will normally include three paychecks instead of two.
Monthly
Monthly means once per month, resulting in 12 payments or deposits per year.
Semi-Monthly
Semi-monthly means twice per month, usually on two established dates such as the 15th and the last day of the month. This normally results in 24 payments or paychecks per year.
Weekly
Weekly means something occurs once every week, resulting in approximately 52 payments or paychecks per year.
Why the distinction matters: Biweekly and semi-monthly may sound similar, but they produce different payment dates and a different number of annual payments.

Accounts, Savings & Transfers
Account Balance
Your account balance is the amount of money currently recorded in an account.
Keep in mind that pending purchases or deposits may not yet be reflected in the displayed balance.
Cash Cushion
A cash cushion is an amount you intentionally keep in your checking account above what is needed for scheduled expenses.
Why it matters: A cushion provides breathing room for timing differences, small unexpected expenses or transactions that post earlier than expected.
Checking Account
A checking account is generally used for everyday transactions such as deposits, purchases, bill payments and transfers.
Emergency Fund
An emergency fund is money reserved for significant, unexpected expenses or a temporary loss of income.
Examples: An urgent home repair, major vehicle repair, medical expense or job loss.
Why it matters: Emergency savings can reduce the need to rely on credit cards or loans when something unexpected happens.

Savings Account
A savings account is generally used to hold money that you do not plan to spend immediately.
Examples: Emergency savings, vacation savings or money reserved for a future purchase.
Sinking Fund
A sinking fund is money saved gradually for an expense you know is coming.
Examples: Holiday spending, car repairs, insurance premiums, travel or replacing an appliance.
Why it matters: The exact cost or date may be uncertain, but the expense itself is predictable. Saving a little at a time makes it easier to handle.

Transfer
A transfer moves money from one account to another. It does not create new income or represent a new expense.
Example: Moving $200 from checking to savings is a transfer. The money still belongs to you—it is simply being held in a different account.
Why someone might make a transfer: Transfers can help reserve money for emergencies, future bills, planned purchases, debt payments or other financial goals.

Debt, Credit & Housing
Credit Limit
A credit limit is the maximum amount a lender allows you to borrow on a revolving credit account, such as a credit card.
Interest
Interest is the cost charged for borrowing money.
The interest rate helps determine how much borrowing will cost over time.
Minimum Payment
The minimum payment is the smallest amount a lender requires you to pay by the due date.
Why it matters: Paying only the minimum can keep an account current, but it may take much longer—and cost considerably more in interest—to eliminate the balance.
Mortgage
A mortgage is a loan used to purchase or refinance real estate. The property generally serves as collateral for the loan.
A monthly mortgage payment may include principal, interest, property taxes and homeowners insurance.
Net Worth
Net worth is the value of what you own minus what you owe.
Example: If your assets total $500,000 and your debts total $200,000, your net worth is $300,000.
Why it matters: Net worth provides a broader picture of your financial position than income alone.

Principal
Principal is the amount borrowed that has not yet been repaid.
When part of a loan payment is applied to principal, the remaining loan balance decreases.
Statement Balance
The statement balance is the amount owed at the end of a credit card billing cycle.
This may differ from the current balance because purchases, payments or credits made after the statement closed are not included.
