Banking and Personal Finance Terms
This category covers the essential tools and services that help people manage their money, from everyday bank accounts to credit, loans, and international transfers. Understanding these terms makes it easier to handle your finances and avoid costly mistakes.
📌Checking Account
A checking account is a bank account used for daily spending—like paying bills, shopping, or withdrawing cash. It typically comes with a debit card and check-writing privileges.
📌Savings Account
A savings account is designed for storing money you don’t need right away and earning interest over time. It usually limits how often you can withdraw money each month.
📌Interest Rate
An interest rate is the percentage a bank pays you for saving money—or the amount you pay when borrowing. It’s how money grows or costs more over time.
📌Compound Interest
Compound interest means you earn interest on your original amount and on the interest already added. Over time, it can grow your money much faster than simple interest.
📌Simple Interest
Simple interest is calculated only on the original amount of money (the principal). It doesn’t increase as quickly as compound interest.
📌Annual Percentage Rate (APR)
APR shows the total yearly cost of borrowing money, including interest and fees. It helps you compare loans or credit cards on equal terms.
📌Annual Percentage Yield (APY)
APY tells you how much interest you’ll earn on savings in a year, factoring in compounding. A higher APY means your money grows faster.
📌Overdraft
An overdraft happens when you spend more than you have in your account. The bank covers the difference, but usually charges you a fee or interest.
📌Minimum Balance
This is the lowest amount of money you must keep in your account to avoid fees or earn interest. Falling below this amount can trigger penalties.
📌Credit Score
A credit score is a number that shows how reliable you are at repaying debt. Lenders use it to decide if they’ll give you a loan or credit card.
📌Credit Limit
Your credit limit is the maximum amount you’re allowed to borrow on a credit card or line of credit. Going over it can lead to fees and harm your credit score.
📌Credit Report
A credit report is a detailed record of your borrowing history, including loans, credit cards, and payment behavior. It’s used to assess your financial trustworthiness.
📌Direct Deposit
Direct deposit means your paycheck or other income goes straight into your bank account electronically. It’s faster and more secure than receiving a paper check.
📌Routing Number
A routing number identifies your bank and is used for transferring money, especially in the U.S. It’s like your bank’s address for sending or receiving funds.
📌SWIFT Code
A SWIFT code is an international banking ID used for global wire transfers. It ensures money reaches the correct bank across countries.
📌Standing Order
A standing order is an instruction you give your bank to pay the same amount regularly to someone, like for rent or a subscription. It’s set up once and runs automatically.
📌Wire Transfer
A wire transfer is a fast, secure way to send money from one bank to another, even across countries. It often comes with a fee but works within hours or a day.
📌Remittance
A remittance is money sent by someone working abroad to family or others in their home country. It’s a major income source for many households worldwide.
📌Bank Statement
A bank statement is a summary of all your account activity—deposits, withdrawals, fees—for a specific period. It helps you track your spending and catch errors.
📌Money Market Account
A money market account combines features of savings and checking accounts, usually offering higher interest and limited check-writing. It often requires a higher minimum balance than regular savings.
📌Emergency Fund
A cash reserve set aside to cover unexpected expenses like medical bills or job loss. It helps you avoid going into debt during a crisis.
📌Logbook Loan
A logbook loan is when you borrow money using your car as collateral. If you don’t repay, the lender can take your vehicle.
📌Principal
The original amount of money you invest or borrow, before interest is added.
📌Debt-to-Income Ratio (DTI)
A measure of how much of your monthly income goes toward debt payments. Lenders use it to assess your creditworthiness.

Gross income is the total amount you earn before any taxes or deductions are taken out. It includes wages, bonuses, rental income, and other earnings.
📌Net Income
Net income is what’s left after taxes and deductions—your actual take-home pay. It’s the amount you can spend or save.
📌Taxable Income
Taxable income is the portion of your income that’s subject to tax after deductions and exemptions are applied. It’s what the government uses to calculate how much you owe.

AGI is your gross income minus specific deductions like student loan interest or retirement contributions. It’s used to determine your eligibility for certain tax benefits.
📌Marginal Tax Rate
Your marginal tax rate is the rate you pay on your next dollar of income. It increases as your income moves into higher tax brackets.
📌Effective Tax Rate
This is the average percentage of your total income that you actually pay in taxes. It’s usually lower than your marginal rate because it accounts for deductions and lower tax brackets.
📌Capital Gains Tax (CGT)
Capital gains tax is charged on profits you make from selling assets like stocks or property. The rate depends on how long you held the asset before selling.
📌Income Tax
Income tax is a government levy on your earnings from work, business, or investments. It’s usually collected through payroll or annual tax filings.

Withholding tax is money taken out of your paycheck or payments by an employer or payer and sent directly to the tax authority. It’s a prepayment of your expected tax bill.
📌Tax Deduction
A tax deduction reduces the amount of income you’re taxed on. Common examples include deductions for mortgage interest, charitable donations, or medical expenses.

A tax credit directly lowers the amount of tax you owe. Unlike deductions, credits are subtracted from your final tax bill dollar-for-dollar.

Tax deferral means delaying payment of taxes to a future date. Retirement accounts like IRAs often allow you to defer taxes until withdrawal.
📌Tax-Efficient Investing
Tax-efficient investing involves choosing assets or strategies that minimize the taxes you owe. This might include holding investments long-term or using tax-sheltered accounts.

Double taxation happens when the same income is taxed in two different jurisdictions—often in both your home country and the country where it was earned. Tax treaties sometimes help avoid this.
📌Offshore Income
Offshore income is money earned from outside your home country. Depending on your tax residency, you may still need to report and pay taxes on it.

VAT is a consumption tax added at each stage of production or distribution. The end consumer ultimately pays it as part of the final purchase price.

GST is a type of sales tax charged on most goods and services. Like VAT, it’s usually included in the price and collected by the seller on behalf of the government.
📌Tax Residency

A legal strategy or vehicle that reduces taxable income, such as retirement accounts or depreciation on rental property.
