- Amortization — Loan Amortization
- The process of paying off a loan through regular payments that cover both principal and interest. Early payments are mostly interest; later payments are mostly principal.
- Why it matters: Understanding amortization explains why paying extra early in a loan saves the most money — you're reducing the principal that interest is calculated on.
- Example: Month 1 of a $200,000 mortgage at 6%: your $1,199 payment splits as $1,000 interest + $199 principal. By month 300: only $47 goes to interest and $1,152 goes to principal.
- Balloon Payment
- A large lump-sum payment due at the end of a loan, after a period of smaller monthly payments. The loan isn't fully paid off by the regular payments — the balloon settles it.
- Why it matters: Balloon payments make monthly payments look affordable but create a financial cliff. If you can't pay or refinance at the end, you could lose your home or asset.
- Example: A 5-year balloon mortgage on $200,000: you pay $1,054/month (as if it were a 30-year loan), but after 5 years you owe a balloon of $186,108 all at once.
- Collateral — Loan Collateral
- An asset you pledge to the lender as security for a loan. If you stop paying, the lender can seize and sell that asset to recover their money.
- Why it matters: Secured loans (with collateral) have lower interest rates because the lender has less risk. But you could lose your home, car, or savings if you default.
- Example: A mortgage uses your house as collateral. A car loan uses your vehicle. A title loan uses your car title. If you miss payments, the lender can foreclose or repossess.
- Cosigner — Loan Cosigner
- A person who agrees to repay your loan if you can't. They're equally responsible for the debt, and their credit is affected by your payment behavior.
- Why it matters: Cosigning helps people with thin credit get approved or get better rates. But it's a huge risk for the cosigner — they're on the hook for the full amount if you default.
- Example: A parent cosigns their child's $30,000 student loan. The child stops paying after 6 months. The parent is now legally required to make the payments or face collections, lawsuits, and credit damage.
- Credit Bureau — Credit Reporting Agency (Bureau)
- A company that collects and sells information about your credit history. The three major bureaus are Equifax, Experian, and TransUnion.
- Why it matters: Not all lenders report to all three bureaus, so your reports may differ. You should check all three reports because an error on one could be costing you money.
- Example: Your car loan only reports to Equifax and TransUnion. Your Experian report doesn't show that good payment history, so your Experian score is 15 points lower.
- Credit Freeze — Security Freeze / Credit Freeze
- A free tool that locks your credit report so no one (including you) can open new accounts until you lift it. It's the strongest protection against identity theft.
- Why it matters: A credit freeze prevents criminals from opening loans in your name, even if they have your Social Security number. It's free by law and doesn't affect your credit score.
- Example: Your data was in a breach. You freeze your credit at all 3 bureaus (takes 10 minutes online). A thief tries to open a credit card in your name — denied because the lender can't pull your frozen report.
- Credit Mix — Credit Mix (Types of Credit)
- The variety of credit accounts you have — credit cards (revolving), auto loans (installment), mortgage, student loans, etc. Having multiple types shows you can manage different kinds of debt.
- Why it matters: Credit mix accounts for about 10% of your FICO score. Having only credit cards isn't as strong as having a card, an installment loan, and a mortgage.
- Example: Borrower A has 3 credit cards. Borrower B has 2 credit cards, a car loan, and a student loan. Even with the same payment history and utilization, Borrower B's score is typically higher.
- Credit Report — Consumer Credit Report
- A detailed record of your borrowing history maintained by credit bureaus. It lists every loan, credit card, payment history, collection, and public record tied to your name.
- Why it matters: Errors on credit reports are common — 1 in 5 consumers has at least one mistake. Checking your report regularly is the first step to fixing errors that are costing you money.
- Example: You pull your free report from AnnualCreditReport.com and find a $2,400 medical collection you already paid. You dispute it, the bureau verifies it's resolved, and your score goes up 40 points.
- Credit Score
- A 3-digit number (300-850) that summarizes how reliably you've handled borrowed money. Higher scores mean lower risk to lenders and better loan terms for you.
- Why it matters: Your credit score determines whether you get approved and at what rate. A 100-point difference can mean thousands of dollars more or less in interest over a loan's life.
- Example: On a $250,000 30-year mortgage: a 760 score gets you 6.2% ($1,536/month). A 660 score gets 7.4% ($1,729/month). Over 30 years, the lower score costs you $69,480 more.
- Credit Utilization — Credit Utilization Ratio
- The percentage of your available credit that you're currently using. If you have $10,000 in credit limits and owe $3,000, your utilization is 30%.
- Why it matters: Utilization is the second-biggest factor in your credit score (after payment history). Keeping it below 30% helps your score; below 10% is ideal.
- Example: You have 3 cards with a $15,000 total limit. You're carrying $4,500 in balances (30% utilization). Paying down to $1,500 (10% utilization) could boost your score by 20-50 points.
- Default — Loan Default
- When you fail to repay a loan according to the agreed terms — usually after 90-180 days of missed payments. It's the point where the lender gives up on collecting normally.
- Why it matters: Default triggers severe consequences: credit score drops 100+ points, the debt may be sent to collections, you could be sued, and your wages or assets could be seized.
- Example: You miss 4 consecutive car payments. The lender declares your loan in default, repossesses your car, sells it at auction for $8,000, and you still owe the remaining $5,000 (called a deficiency balance).
- FICO Score — Fair Isaac Corporation Score
- The most widely used credit scoring model, created by Fair Isaac Corporation. 90% of top lenders use FICO scores for lending decisions.
- Why it matters: FICO has many versions (FICO 8, 9, 10). Mortgage lenders still use older versions (FICO 2, 4, 5), so your mortgage score may differ from what free apps show you.
- Example: Your FICO 8 score (used for credit cards) is 740. Your FICO 5 score (used for mortgages) is 725 because it weighs collections differently. Same credit history, different scores.
- Hard Inquiry — Hard Credit Inquiry (Hard Pull)
- When a lender checks your credit report because you've applied for credit. Each hard inquiry can lower your score by 5-10 points and stays on your report for 2 years.
- Why it matters: Multiple hard inquiries in a short period suggest you're desperately seeking credit, which is a red flag. Exception: mortgage and auto loan shopping within 14-45 days counts as one inquiry.
- Example: You apply for 5 credit cards in one month. Each application triggers a hard inquiry. Your score drops 25-50 points from the inquiries alone, making each subsequent application harder.
- Loan Term (Tenor) — Loan Term / Tenor
- How long you have to repay the loan, measured in months or years. A shorter term means higher monthly payments but less total interest paid.
- Why it matters: Longer terms feel more affordable monthly but cost much more overall. A 30-year mortgage costs almost double in interest compared to a 15-year mortgage on the same amount.
- Example: Borrowing $200,000 at 6.5%: A 15-year term costs $1,742/month ($113,561 total interest). A 30-year term costs $1,264/month ($255,088 total interest). You save $141,527 with the shorter term.
- Origination Fee — Loan Origination Fee
- A one-time fee the lender charges to process and set up your loan. It covers their costs for underwriting, verifying your information, and preparing paperwork.
- Why it matters: Origination fees are usually 1-8% of the loan amount and are often deducted from your loan proceeds — so you receive less than you borrowed.
- Example: You're approved for a $10,000 personal loan with a 5% origination fee. The lender deducts $500 upfront, so you receive $9,500 in your bank account but owe $10,000 plus interest.
