Annual Percentage Rate (APR)

The yearly cost of borrowing shown as a percentage, including interest and most fees. It lets a borrower compare loan offers on one common scale rather than by interest rate alone.

Related: Finance Charge, Compound Interest
Finance Charge

The total dollar amount paid to use credit, covering interest plus fees such as origination or service charges. It appears on credit card and installment loan disclosures.

Related: Annual Percentage Rate (APR), Minimum Payment
Compound Interest

Interest calculated on both the original amount and previously earned interest, so the balance grows faster over time. The same effect works against borrowers carrying unpaid credit card balances.

Related: Annual Percentage Rate (APR), Future Value
Credit Utilization Ratio

The share of available revolving credit a person is actually using, usually computed per card and overall. High utilization signals risk to lenders and can lower credit scores.

Related: Credit Score, Minimum Payment
Credit Score

A number summarizing how reliably a person has repaid debt, derived from payment history, amounts owed, length of history, new credit, and credit mix. Lenders use it to price and approve loans.

Related: Credit Utilization Ratio, Secured Credit Card
Secured Credit Card

A card requiring a cash deposit that becomes the credit limit, reducing risk for the issuer. It is often used to rebuild a damaged credit history.

Related: Credit Score, Grace Period
Grace Period

The interval after a statement closes during which a cardholder can pay the full balance and owe no interest on purchases. Carrying a balance usually ends this benefit.

Related: Minimum Payment, Secured Credit Card
Minimum Payment

The smallest amount a creditor requires by the due date to keep an account current. Paying only this amount stretches repayment for years and increases total interest.

Related: Finance Charge, Grace Period
Debt-to-Income Ratio

Monthly debt obligations divided by gross monthly income, expressed as a percentage. Lenders use it to judge whether a borrower can handle an additional payment.

Related: Preapproval, Private Mortgage Insurance (PMI)
Preapproval

A lender's written estimate of how much it will lend a buyer, based on verified income, assets, and credit. It strengthens an offer but is not a guarantee of final financing.

Related: Debt-to-Income Ratio, Earnest Money
Earnest Money

A deposit a buyer puts down to show serious intent to complete a purchase. It is typically credited toward the purchase price but can be forfeited if the buyer backs out without a contractual escape.

Related: Preapproval, Closing Costs
Closing Costs

Fees and charges paid at the final settlement of a real estate purchase, such as loan origination, title insurance, and recording fees. Buyers should budget for them separately from the down payment.

Related: Earnest Money, Private Mortgage Insurance (PMI)
Private Mortgage Insurance (PMI)

Insurance a lender requires when a home buyer's down payment falls below roughly twenty percent. It protects the lender, not the borrower, and adds to the monthly payment.

Related: Debt-to-Income Ratio, Closing Costs
Depreciation

The decline in a vehicle's market value over time, steepest in the first years of ownership. It is often the largest cost of new-car ownership and matters when comparing buying with leasing.

Related: Lease, Residual Value
Lease

A contract granting use of an asset for a set period in exchange for payments, without transferring ownership. Vehicle leases typically cap mileage and charge for excess wear.

Related: Depreciation, Residual Value
Residual Value

The projected worth of a leased asset at the end of the contract term. It drives monthly lease payments and sets the buyout price a lessee may pay to keep the asset.

Related: Lease, Depreciation
Adjusted Gross Income (AGI)

Gross income minus certain above-the-line adjustments such as retirement contributions and student loan interest. It is the starting point for many deductions, credits, and phase-outs.

Related: Taxable Income, Standard Deduction
Taxable Income

The amount on which income tax is actually computed, after subtracting adjustments and either the standard or itemized deduction. Tax brackets apply to this figure, not to total earnings.

Related: Adjusted Gross Income (AGI), Standard Deduction
Standard Deduction

A fixed amount most filers may subtract from income instead of tracking individual deductible expenses. Taxpayers generally choose whichever is larger between it and their itemized deductions.

Related: Itemized Deductions, Taxable Income
Itemized Deductions

Specific expenses a taxpayer lists individually, such as mortgage interest, charitable gifts, and state taxes paid. They reduce taxable income only when their total exceeds the standard deduction.

Related: Standard Deduction, Tax Credit
Tax Credit

A direct reduction of the tax owed, dollar for dollar, rather than a reduction of taxable income. Credits are generally more valuable than an equal-sized deduction.

Related: Itemized Deductions, Withholding
Withholding

Income tax an employer removes from each paycheck and sends to the government on the employee's behalf. Too little withholding can create a balance due; too much produces a refund.

Related: Tax Credit, Adjusted Gross Income (AGI)
Marginal Tax Rate

The rate applied to the next dollar of taxable income, determined by the bracket that dollar falls into. It differs from the effective rate, which is total tax divided by total income.

Related: Taxable Income, Tax-Deferred
Premium

The amount paid, usually monthly or annually, to keep an insurance policy in force. It is owed regardless of whether a claim is ever filed.

Related: Deductible, Coinsurance
Deductible

The amount an insured person pays out of pocket before the insurer begins paying a covered claim. Choosing a higher deductible usually lowers the premium.

Related: Premium, Coinsurance
Coinsurance

The share of covered costs the insured pays after the deductible is met, often stated as a percentage split with the insurer. It continues until an out-of-pocket maximum is reached.

Related: Deductible, Premium
Umbrella Policy

Extra liability coverage layered above auto and homeowners limits to protect against large claims or lawsuits. It is relatively inexpensive because it applies only after underlying coverage is exhausted.

Related: Premium, Beneficiary
Beneficiary

The person or entity named to receive policy proceeds or account assets upon the owner's death. Designations generally override instructions in a will.

Related: Umbrella Policy, Probate
Diversification

Spreading money across different assets, sectors, and regions so that one poor performer cannot sink the whole portfolio. It reduces company-specific risk but not overall market risk.

Related: Mutual Fund, Risk Tolerance
Mutual Fund

A pooled investment that combines money from many shareholders to buy a diversified portfolio managed professionally. Shares are priced once daily at net asset value.

Related: Diversification, Expense Ratio
Expense Ratio

The annual percentage of a fund's assets deducted to cover management and operating costs. Small differences compound into large sums over decades of investing.

Related: Mutual Fund, Compound Interest
Risk Tolerance

A person's willingness and financial ability to accept investment losses in pursuit of higher returns. It shapes how much should be held in stocks versus safer assets.

Related: Diversification, Asset Allocation
Asset Allocation

The mix of stocks, bonds, cash, and other asset classes in a portfolio. It is a primary driver of both long-run return and short-term volatility.

Related: Risk Tolerance, Diversification
Bond

A loan an investor makes to a government or corporation that pays periodic interest and returns principal at maturity. Bond prices generally fall when market interest rates rise.

Related: Asset Allocation, Mutual Fund
Tax-Deferred

Describing an account or investment whose earnings are not taxed until money is withdrawn. Deferral lets the full balance keep compounding in the meantime.

Related: Marginal Tax Rate, Required Minimum Distribution (RMD)
Required Minimum Distribution (RMD)

The minimum amount that must be withdrawn annually from most traditional retirement accounts after a set age. Failing to take it triggers a substantial penalty tax.

Related: Tax-Deferred, Probate
Probate

The court-supervised process of validating a will and distributing a deceased person's assets. It is public and slow, which is why people use trusts and beneficiary designations to avoid it.

Related: Beneficiary, Power of Attorney
Power of Attorney

A legal document authorizing one person to act on another's financial or medical decisions. A durable version remains effective if the principal becomes incapacitated.

Related: Probate, Beneficiary
Future Value

The amount a sum will grow to after earning interest over time at a given rate. It underlies savings and retirement projections and depends heavily on the number of compounding periods.
