Step 1: The lesson

What are the main types of loans?

Credit cards are revolving credit. Most other loans are installment loans: you borrow a set amount, then repay it in equal payments over a set time.

Key term

Principal and term

The principal is the amount you borrow. The term is how long you have to repay it — for example, 60 months.

  • Auto loans — for a car. The car secures the loan.
  • Student loans — for education. Federal student loans have protections and repayment options that private loans usually don't.
  • Personal loans — for almost anything. Usually unsecured, so rates depend heavily on your credit.
  • Mortgages — for a home. The home secures the loan, and terms are often 15 or 30 years.

Key term

Secured vs. unsecured

A secured loan is backed by something the lender can take if you stop paying — like repossessing a car. An unsecured loan isn't, so it usually costs more.

The key tradeoff is term. A longer term makes each payment smaller but costs more interest in total. Compare loans by APR and total cost, not just the monthly payment.

Think hard before co-signing

A co-signer is fully responsible for the loan if the borrower doesn't pay. It shows up on the co-signer's credit, and missed payments hurt both people.

Step 2: See it

A $20,000 car loan at 7% APR: total interest by term

A $20,000 car loan at 7% APR: total interest by termHypothetical example

For a $20,000 loan at 7% APR, a 3-year term costs about $2,232 in interest, a 5-year term about $3,761, and a 7-year term about $5,356.

Step 3: Real-world example

"What monthly payment works for you?"

At a car dealership, a salesperson asks Alex what monthly payment fits the budget. Alex says $300.

The dealer finds a way: a 7-year loan on a $20,000 car at 7% — about $302/month. It fits. But the total interest is about $5,356, compared with $2,232 on a 3-year loan.

A better approach: decide on a total price first, get pre-approved by a bank or credit union so you know your rate, and choose the shortest term you can comfortably afford.

Step 4: Try it

Step 5: Knowledge check

Quiz: Types of Loans (3 questions)

Answer each question, then check your answer to see the explanation. Retake it as many times as you like.

Question 1 of 3

ScenarioTwo car loans have the same amount and the same APR. One lasts 3 years, the other 6.Which costs more in total interest?

Choose an answer.

Step 6: Summary

Summary: Types of Loans

Installment loans have a fixed amount, fixed payments, and an end date. Secured loans are backed by collateral; unsecured loans aren't and usually cost more. Longer terms lower the payment but raise the total cost. Compare APR and total cost, and be careful about co-signing.

Step 7: What you should remember

Key takeaways: Types of Loans

  • Installment loans: fixed amount, fixed payments, set end date.
  • Secured loans have collateral that can be taken if you don't pay.
  • Longer term = smaller payment, more total interest.
  • Shop by APR and total cost, not monthly payment.
  • Co-signers are fully on the hook.
