Loans 101 — What Borrowing Really Costs
🏷️ The sticker price of a loan is a polite lie. Borrow $30,000 for a car and you might hand back $36,000 — the extra $6,000 is rent you paid for using money that wasn't yours. The dealership prefers to call it 'affordable monthly payments.'
💡 Key idea
Loans repay principal + interest over a term. Longer term = lower payment but more total interest. Judge the total cost, not the monthly.
🧠 Why it matters
A LOAN gives you a lump sum now that you repay in fixed installments over time, with interest. Most loans are AMORTIZED: early payments are mostly interest, later payments mostly principal — so at the start you're barely denting what you owe. Two numbers decide the real cost: the INTEREST RATE and the TERM (length). A longer term means smaller monthly payments but MORE total interest. Salespeople love quoting the monthly payment because it hides the total cost. Always look at what you repay in total, not just per month.
🌍 In the real world
💡 Stretch a car loan from 4 years to 7 to get a 'lower payment,' and you'll pay thousands more in interest while owing more than the car is worth for years. The low monthly number is the bait; the total repaid is the real price.
📌 Takeaways
- Loans repay principal + interest in installments over a term
- Amortization: early payments are mostly interest
- Longer term = lower payment but more total interest paid
📖 Terms in this lesson
Principal: The original amount you borrowed or invested, before interest is added.
Secured debt: A loan backed by something the lender can take if you don't pay, like a car or a house.
Unsecured debt: A loan with nothing backing it, like a credit card, so the rate is higher.
Collateral: The thing a lender can take if you stop paying a secured loan.
Loan term: How long you have to pay a loan back; longer means smaller payments but more interest overall.
Default: Failing to pay a loan as agreed, which damages your credit for years.
✅ Test yourself
In an amortized loan, early payments are mostly...
- Principal
- Interest
- Fees
- Savings
Answer: B · Interest
Amortization front-loads interest, so early on you barely reduce the principal.
A longer loan term usually means...
- Less total interest
- A lower monthly payment but more total interest
- No interest
- A higher monthly payment
Answer: B · A lower monthly payment but more total interest
Stretching the term lowers the monthly payment but increases total interest paid.
