Kim wants to borrow $12,000 to buy a used car. One lender offers an auto loan with a fairly low interest rate, but the car would be used as collateral. Another lender offers an unsecured personal loan with a higher rate, and it does not ask for the car.
Both options give Kim the money she needs, and both come with monthly payments. However, they do not put her at the same risk. The key difference comes down to one word: collateral.
The main difference between secured and unsecured loans
A secured loan is backed by something you own, so if you do not repay as agreed, the lender can take that asset. An unsecured loan is not backed by a specific asset. Instead, approval depends more on your credit history, income, existing debts and ability to repay.
| Feature | Secured loan | Unsecured loan |
|---|---|---|
| Collateral | Yes, something you own | No specific asset |
| Common examples | Mortgages, auto loans, home equity loans, savings-secured loans | Many personal loans and most credit cards |
| Risk for the lender | Lower, because an asset backs the debt | Higher, because nothing backs the debt |
| Interest rate | Often lower | Often higher |
| If you stop paying | The lender may take and sell the asset | The lender may use collections or go to court |
| Effect on your credit | Late payments can hurt your score | Late payments can hurt your score |
General comparison. Each loan’s terms depend on the lender and on your situation.
In short, a secured loan is not automatically better just because the rate is lower. Likewise, an unsecured loan is not free of consequences just because nothing is pledged. A good comparison looks at both the cost and what happens if things go wrong.
MONEY TRAPWhy “secured” sounds safe
“A secured loan sounds safer. Besides, the rate is lower, so it must be the better deal.”
The word “secured” describes the lender’s protection, not yours. You get a lower rate because you put something you own on the line, like your car or your home.
Why “secured” can feel safer than it is
Words shape how a choice feels. Psychologists Amos Tversky and Daniel Kahneman showed in a famous study, The Framing of Decisions and the Psychology of Choice, that people often make different choices when the same facts are described in different words. That is called framing.
“Secured” is a good example. In everyday language, the word sounds protective, so it is easy to assume it protects you. In fact, the security belongs to the lender. As a result, the lender takes less risk, and you take more: if repayment fails, you could lose something important.
There is a second trap. Most of us expect things to go better for us than they do for the average person, a pattern known as the optimism bias, described by neuroscientist Tali Sharot in Current Biology. When we sign a loan, we picture ourselves paying every month. Because of that, the risk of losing the car or the home can feel distant, even though job loss, illness or a big repair can happen to anyone.
A simple question helps you get past both traps: what would losing this asset do to the rest of my life?
What collateral means
Collateral is something valuable that you pledge when you take out a loan. Depending on the loan, it could be a home, a car, money in a savings account or certificate of deposit, or other property the lender accepts.
Usually, the lender gets a legal claim on that asset, called a lien. For example, when you finance a car, you can still drive it, but the lender keeps a claim on it until the loan is paid off. Once you repay the loan, the lender generally releases that claim.
Collateral is not a down payment
A down payment is money you put toward a purchase at the start. Collateral is the asset that backs the debt you still owe. Say a car costs $20,000 and you pay $4,000 upfront. In that case, you borrow $16,000, the $4,000 is your down payment and the car itself is the collateral for the $16,000 loan.
A cosigner is not collateral
A cosigner is a person who agrees to pay the debt if you do not. That promise may help you qualify, but a cosigner is a person, not an asset. In fact, both arrangements create serious obligations, although they work in different ways.
How secured loans work
Because there is an asset behind the debt, secured loans reduce part of the lender’s risk. For instance, a mortgage is secured by a home, an auto loan by the car, and some bank and credit union loans by money in a savings account or certificate of deposit.
Since the lender has another way to get its money back, secured loans may come with lower rates, higher limits or longer terms. These are possibilities, not guarantees, because the lender will still look at your income, credit and debts. Above all, remember that collateral does not make an unaffordable loan affordable. It only changes who carries the risk.
How unsecured loans work
An unsecured loan is not tied to a specific item. Instead, the lender looks at you: your credit reports and scores, income, job, current debts, the amount you want and the length of the loan. For example, many personal loans are unsecured, and so are most credit cards.
Without collateral, a lender may see the loan as riskier, so it may charge a higher rate, offer a smaller amount or set stricter rules. Even so, these differences are not universal. A borrower with strong credit could get a better unsecured offer than someone else gets on a secured loan. For that reason, the label alone does not tell you whether an offer is good. If you are new to these terms, start with What Is Credit and How Does It Work? and How Loans Work.
A $12,000 example: secured vs. unsecured
Back to Kim. Suppose she gets two offers for $12,000, both with fixed rates, 36 monthly payments and no fees:
| Loan feature | Secured auto loan | Unsecured personal loan |
|---|---|---|
| Amount borrowed | $12,000 | $12,000 |
| Interest rate | 7% | 11% |
| Term | 36 months | 36 months |
| Monthly payment | $370.53 | $392.86 |
| Total interest | $1,338.91 | $2,143.13 |
| Total repaid | $13,338.91 | $14,143.13 |
| Collateral | The car | None |
Original Money Behaves calculation. Fixed rates, equal monthly payments and no fees.
On paper, the secured loan saves Kim about $22 a month and $804 in total interest. So, looking only at the numbers, it is cheaper.
However, the numbers are not the whole decision. If Kim stops paying the auto loan, the car can be repossessed, and losing it could make it hard to get to work, look after her family or earn income. With the personal loan, by contrast, the lender cannot automatically take the car, because it was never pledged. Even then, Kim could still face late fees, credit damage, collections or a lawsuit.
What happens if you stop paying
Both types of loan are serious commitments. In both cases, missing payments can lead to late fees, more interest, a lower credit score, collections, legal action and trouble borrowing in the future. The big difference is what happens to the collateral, as you can see below:
SECURED LOAN
If you stop paying a car loan
- First, late fees and extra interest are added.
- Then late payments are reported and your credit score drops.
- After that, the lender can take the car (repossession) or the home (foreclosure).
- Next, the asset is sold, and you may still owe the difference.
- Finally, any remaining debt can go to collections or court.
UNSECURED LOAN
If you stop paying a personal loan
- First, late fees and extra interest are added.
- Then late payments are reported and your credit score drops.
- After that, the account can be sent to a debt collector.
- Also, the lender can sue you, and a court judgment can allow other ways to collect, depending on your state.
- However, no specific item can be taken automatically, because nothing was pledged.
Simplified overview. The exact steps and protections depend on the loan agreement and the law in your state.
Losing the asset may not end the debt
With a secured loan, the lender may take the asset: a car can be repossessed and a home can be foreclosed on. Even so, losing the asset does not always clear what you owe. Imagine you still owe $10,000 on a car when it is repossessed. Then the lender sells it for $7,500 and adds $500 in allowed repossession costs:
$10,000 + $500 − $7,500 = $3,000 still owed
That leftover amount is called a deficiency balance. In other words, you could lose the car and still owe money. The Federal Trade Commission explains how repossession and deficiency balances work and what rights you may have.
No collateral does not mean no consequences
An unsecured lender cannot simply take an item that was never pledged. Still, it has other ways to collect. For example, the account may be sent to a debt collector, and the lender may file a lawsuit. If it wins a court judgment, other ways to collect may be available, depending on your state. The FTC’s debt collection guide explains what collectors can and cannot do.
How to compare the two the smart way
First, compare APR and fees, not only the advertised rate, and compare the same amount over a similar term. After that, check for origination fees, late fees, early repayment rules and optional add-ons, and find out whether the rate is fixed or variable. Our guide on How to Compare Loan Offers walks through each step.
For a secured loan, also find out exactly what property backs the debt. Do not assume it is only the item you are buying, so read the agreement carefully. Finally, think about what would happen if your income dropped for a while, an emergency came up or the asset lost value faster than expected. That is not pessimism. Rather, it is part of judging a commitment that can last for years.
Common mistakes to avoid
- Thinking “secured” means safer for you. The security is mainly for the lender.
- Treating unsecured debt as harmless. Defaulting can still lead to credit damage, collections and legal action.
- Assuming collateral guarantees approval. In fact, a lender can still say no, and approval does not prove the payment fits your budget.
- Focusing only on the lowest monthly payment. A longer term lowers the payment but raises the total cost.

Next time you choose between a secured and unsecured loan, check this
- Ask who the word “secured” protects. Usually, the answer is the lender.
- Name the asset at risk. Then picture your life without it for a few months.
- Compare the savings with the risk. For example, is $22 a month worth putting your only car on the line?
- Check the total cost, not just the rate. Look at APR, fees and the total of payments.
- Plan for a bad month. Make sure you have some savings before you pledge something you cannot live without.
