Secured vs. Unsecured Personal Loans: Costs and Risks
Secured vs. unsecured personal loans compared: how collateral affects rates, what you risk if you default, and a computed $15,000 cost example.
Short answer: a secured personal loan is backed by collateral you pledge, such as a savings balance or a vehicle, while an unsecured personal loan is backed only by your promise to repay. Because collateral lowers the lender's risk, secured loans may carry a lower interest rate, but if you cannot repay, the lender can take the collateral. Unsecured loans put no specific asset at risk, though lenders may charge more for them.

What Makes a Personal Loan Secured or Unsecured?
The FDIC puts it plainly: with a secured loan, "you pledge collateral to secure repayment of the loan," and collateral is "an asset you own, such as your house, vehicle or cash." If you stop paying, "the lender can take your collateral and use it to get some or all of their money back," and you may still owe the remaining balance if the collateral does not cover the debt. Unsecured loans, in the FDIC's words, "are made based only on your promise to repay the money you borrow," and lenders "may charge a higher interest rate than for a secured loan" because they consider them riskier. Both points are from the FDIC's consumer guide to loans.
Common forms of collateral for personal-sized loans include a savings account or certificate of deposit held at the lender, or a vehicle. Availability varies by lender, so ask each one what it accepts. Check each lender's current offerings rather than assuming a secured option exists.
How the Cost Can Differ: A Computed Example
Lender pricing varies, so the numbers below are assumptions, not quotes. Suppose a borrower is offered 10% APR on a secured loan and 14% APR on an unsecured loan for the same $15,000 over 48 months, with no origination fee on either. Computed with the standard amortization formula in Python:
| Secured (10% APR) | Unsecured (14% APR) | Difference | |
|---|---|---|---|
| Monthly payment | $380.44 | $409.90 | $29.46 |
| Total interest over 48 months | $3,261.06 | $4,675.06 | $1,414.00 |
A four-point spread saves roughly $1,400 in this example. But the saving is only real if the rate gap exists in the offers you actually receive. Some secured loans carry fees, and some unsecured lenders price very competitively for borrowers with strong profiles. Compare the APR and the fee on each, and see origination fees vs. APR.
For federal credit unions, the NCUA currently allows loan interest up to an 18% ceiling, extended through September 10, 2027. That is a ceiling on the rate, not a prediction of any particular offer.
What Happens If You Cannot Repay
This is the dimension that rate-focused comparisons often skip.
Unsecured loan. No asset is pledged. If you do not repay, the CFPB notes the lender can pursue debt collection, report negative information on your credit report, and might sue you. Learn more in the CFPB's secured and unsecured loan teaching guide.
Secured loan. The lender has a claim on the collateral. If the collateral is a deposit the lender already holds, the lender may be able to apply it to the debt. If it is a vehicle or other property, the lender may repossess it, and under the FDIC's description you may owe the remaining balance if the sale does not cover the loan. The loan agreement spells out the process, so read it before signing.
The practical question: could you manage without the pledged asset if your income changed? If the answer is no, that is a reason to weigh an unsecured option more heavily, or to borrow less. See how to read a personal loan agreement and our guide to hardship options.
Feature-by-Feature Comparison
| Feature | Secured personal loan | Unsecured personal loan |
|---|---|---|
| Collateral | Required (savings, CD, vehicle or other, depending on lender) | None |
| Interest rate | May be lower, per the FDIC; varies by lender | May be higher, per the FDIC; varies by lender |
| What underwriting weighs | Your credit and income, plus the collateral | Your credit and income |
| If you default | Lender can take the collateral and you may still owe a balance | Collections, credit reporting and possible lawsuit |
| Typical speed | Depends on the collateral; deposit-backed is often simple | Many online lenders fund in a few business days |
| Often considered by | Borrowers with assets to pledge and a need for a lower rate | Borrowers who prefer not to put an asset at risk |
When a Secured Loan May Be Worth Considering
- You have a savings balance or CD you can afford to tie up and want to compare its cost with an unsecured rate. Keep in mind the pledged amount may be unavailable while the loan is open.
- You are building credit. A credit builder loan is a related product in which the lender holds the loan money as savings while you repay over about six to 24 months, then releases it. The CFPB describes it as a way to build savings and credit history at once. It is not the same as a general-purpose personal loan because the money is not available for spending.
- Your unsecured offers are expensive. Compare them with secured alternatives, including a co-signer or joint application, which also change pricing and risk.
When an Unsecured Loan May Fit Better
- You do not want an asset tied to the loan or at risk of repossession.
- You need to keep your savings liquid.
- You want to compare many lenders quickly. Online lenders commonly offer prequalification, so you can see indicative terms before applying.
- The rate gap on your actual offers is small once fees are included.
Questions to Ask a Lender Before You Choose
- Do you offer both secured and unsecured loans, and how do the APRs compare for the amount and term I need?
- What collateral do you accept, and is any of it frozen or unavailable to me while the loan is open?
- What exactly happens, and on what timeline, if I miss a payment or default?
- Is there an origination fee or prepayment penalty on either product, and does paying off early release the collateral right away?
- How will the loan be reported to the credit bureaus?
Write the answers next to each offer, then compare total cost (interest plus fees) at the same term. If a lender will not answer clearly, treat that as a reason to compare further.
Frequently Asked Questions
Is a secured personal loan cheaper than an unsecured one? It can be, because collateral reduces the lender's risk, which the FDIC says may mean a lower rate. It depends on the lender, the collateral and the fees, so compare actual offers using APR and total cost.
Can I lose my savings or car with a secured personal loan? If you cannot repay, the lender can take the pledged collateral, and you may owe the remaining balance. Read the default terms in your agreement.
Does an unsecured personal loan have no consequences for default? No. The CFPB notes that lenders can pursue collection, report the debt to credit bureaus and may sue.
Which is better for building credit? Credit builder loans are designed for that purpose, with payments reported to credit bureaus, according to the CFPB. A general personal loan is designed to provide funds. Compare purposes, not just labels. See how a personal loan affects your credit.
Can I qualify for a secured loan with weaker credit? Approval is never guaranteed and each lender decides how much weight collateral carries. Ask lenders directly, and use prequalification to see indicative terms without a commitment.
How do I estimate the monthly payment on each? Use the loan calculator with the APR, amount and term from each offer, or the affordability calculator to check the payment against your budget.
