A loan product is a lender’s packaged borrowing contract: a bank, credit union, or other lender gives you a sum of money, and you agree to pay it back on a defined schedule with interest. What makes one loan product different from another is how four basic pieces are configured, the principal, the rate, the term, and whether anything is pledged as collateral. Change those pieces and you get the full range of what lenders sell, from a 30-year mortgage to a revolving business line of credit.
The Four Parts Every Loan Product Has
Strip away the marketing and every loan product is built from the same four components.
The principal is the amount of money the lender hands you. Each payment you make puts some money toward reducing that balance.
The interest rate is the lender’s price for letting you use its money. Most lenders quote it as an Annual Percentage Rate. Under federal regulations, the APR must be disclosed to you as “the cost of your credit as a yearly rate,” and it folds in certain mandatory fees along with the stated interest.1eCFR. 12 CFR 1026.18 – Content of Disclosures That’s why APR is a better comparison tool than the raw interest rate when you’re shopping offers.
The term is how long you have to pay everything back. Terms range from a few months on short-term business financing to 30 years on a residential mortgage. A longer term shrinks each payment but increases total interest paid.
Finally, collateral is any asset you pledge that the lender can seize if you stop paying. A mortgage uses the home; an auto loan uses the car. Pledging collateral lowers the lender’s risk, which is why secured loans almost always carry lower rates than unsecured ones.
Fixed Rate or Variable Rate
A fixed-rate loan locks in your interest rate for the whole term. The monthly payment doesn’t move, which makes budgeting straightforward. Most conventional mortgages, auto loans, and personal loans are fixed.
A variable-rate loan starts at one rate and then recalculates periodically against a market benchmark. For U.S. dollar loans today, the dominant benchmark is the Secured Overnight Financing Rate, or SOFR, which measures the cost of overnight borrowing backed by Treasury securities.2Federal Reserve Bank of New York. Transition from LIBOR Your lender adds a fixed margin to the index to set your rate, so if SOFR is at 4% and your margin is 2.5%, you pay 6.5% until the next scheduled adjustment.
Adjustable-rate mortgages show how this plays out. A “5/6m ARM” holds the initial rate for five years, then adjusts every six months.3Consumer Financial Protection Bureau. Adjustable Rate Mortgages Rate caps limit how far the rate can move at each adjustment and across the life of the loan. A variable rate can save money when rates fall. It also exposes you to increases years down the road that you can’t predict when signing.
Secured or Unsecured, Term or Revolving
Beyond the rate structure, loan products split along two more lines: whether there’s collateral behind the debt, and how you access the money.
A secured loan is tied to a specific asset. The lender records a legal claim and can take possession if you default. Because the lender has recourse, rates on mortgages, auto loans, and other secured products are typically lower. An unsecured loan rests entirely on your credit history and income. With nothing to repossess, the lender charges more to offset the risk. Most credit cards and many personal loans are unsecured.
A term loan gives you a single lump sum and a fixed repayment schedule that ends on a specific date. Each payment follows an amortization schedule until the balance hits zero. A revolving credit facility works differently. The lender approves a credit limit, and you can borrow, repay, and borrow again up to that limit for as long as the account is open. You pay interest only on what you’ve actually drawn. Credit cards and business lines of credit are the common revolving products.
Loan Products for Consumers
Mortgages
A mortgage is the largest loan most people ever take on. You borrow to buy residential property, and the property itself secures the debt. Common terms are 15 or 30 years. Mortgage amortization has a quirk worth knowing: in the early years, the majority of each payment goes to interest rather than principal, so extra payments early in the loan can take years off the back end.
HELOCs
A home equity line of credit lets you borrow against the equity you’ve built in your home. It’s structured as a revolving facility, with a draw period when you can tap funds as needed, followed by a repayment period that typically runs 10 to 15 years after the draw period ends.4Consumer Financial Protection Bureau. What You Should Know About Home Equity Lines of Credit HELOC rates are almost always variable, tied to an index like the prime rate.
Auto Loans
Auto loans are secured term loans with the vehicle as collateral. The lender’s claim is recorded on the title, and if you default, the lender can repossess. In many states, repossession can begin as soon as you miss a payment, depending on how the contract defines default.5Federal Trade Commission. Vehicle Repossession Terms typically run three to seven years. Shorter terms cost more each month but less in total interest.
Personal Loans
Personal loans are lump-sum term loans that can be either secured or unsecured. The money isn’t tied to a specific purchase, which is why borrowers often use them to consolidate higher-interest debt or cover large unexpected costs. Unsecured approval leans heavily on your credit score and debt-to-income ratio. Secured versions, backed by a certificate of deposit or an investment account, usually come with lower rates.
Student Loans
Federal student loans are one of the few consumer products where the government itself is the lender. The main types are Direct Subsidized Loans, where the government pays interest while you’re in school, and Direct Unsubsidized Loans, where interest accrues from day one. For the 2025–2026 academic year, undergraduate Direct Loans carry a fixed rate of 6.39%, graduate Direct Unsubsidized Loans sit at 7.94%, and Direct PLUS Loans for parents and graduate students are at 8.94%.6Federal Student Aid. Interest Rates and Fees for Federal Student Loans Private student loans exist too, but they lack the income-driven repayment plans and forgiveness programs tied to federal loans.
Loan Products for Businesses
Term Loans and Lines of Credit
A business term loan looks much like its consumer counterpart. You get a lump sum, repay on a fixed schedule, and the loan closes when the balance reaches zero. Businesses usually reach for term loans when they need the full amount upfront, for equipment, real estate, or an expansion project.
A business line of credit is the revolving option, giving the business access to a set credit limit for inventory purchases, seasonal cash gaps, or other short-term working capital. Interest is charged only on what you actually draw, not on the full limit. Many business lines require collateral such as accounts receivable or inventory.
SBA 7(a) Loans
The Small Business Administration’s 7(a) program is the agency’s main channel for getting capital to small businesses. These aren’t government loans in a literal sense. A private bank or credit union makes the loan, and the SBA guarantees a portion, making lenders more willing to extend credit to smaller or less-established firms.7U.S. Small Business Administration. 7(a) Loans The guarantee percentage varies by product, from 50% on SBA Express loans up to 90% on certain export loans of $350,000 or less.8U.S. Small Business Administration. Types of 7(a) Loans
The maximum under the standard 7(a) program is $5 million, and the funds can be used for real estate, equipment, working capital, and business acquisitions, among other purposes.7U.S. Small Business Administration. 7(a) Loans Interest rates are negotiated between borrower and lender but can’t exceed SBA caps, which are pegged to the prime rate or an optional peg rate plus a size-based spread. On loans over $350,000, for instance, the rate can’t exceed the base rate plus 3%.9U.S. Small Business Administration. Terms, Conditions, and Eligibility
What You Pay Beyond Interest
Interest isn’t the only cost of a loan product. Most carry additional fees that increase the true price of borrowing.
An origination fee covers the lender’s cost of processing your application and setting up the loan. On mortgages, it commonly runs 0.5% to 1% of the loan amount. Some lenders split the charge into separate “processing” and “underwriting” fees, but the labeling is largely cosmetic.
Mortgages add their own closing-cost layer. Recording fees, title insurance, appraisal charges, and any mortgage taxes vary widely by location. Federal law requires lenders to provide a Loan Estimate within three business days of your application so you can compare total costs before committing. For mortgages, you must also receive a Closing Disclosure at least three business days before closing,10Consumer Financial Protection Bureau. When Do I Get a Closing Disclosure? a five-page form laying out the final loan terms, projected monthly payments, and all closing costs.11Consumer Financial Protection Bureau. What Is a Closing Disclosure? Compare it against the Loan Estimate before you sign.
Business loans secured by specific assets often involve state filing fees to register the lender’s security interest. Those filings are typically modest but add to upfront costs. Some revolving products also charge annual maintenance fees or inactivity fees if the line goes unused for a long stretch.
Protections Built Into Federal Law
Adverse Action Notices
If a lender denies your application, it can’t simply go silent. Under the Equal Credit Opportunity Act and the Fair Credit Reporting Act, the lender must send you an adverse action notice explaining why. The notice has to list the specific reasons for the denial, and if a credit score played a role, the key factors that dragged the score down. You generally receive it within 30 days of the completed application. The notice often surfaces fixable problems, like an error on your credit report, that you’d otherwise never catch.
The Three-Day Right of Rescission
For certain mortgage-related transactions that put a security interest on your primary home, federal law gives you a three-day cooling-off window. You can cancel until midnight of the third business day after closing, after receiving the required disclosures, or after receiving all material terms, whichever comes last.12Consumer Financial Protection Bureau. 12 CFR 1026.23 – Right of Rescission This applies to refinances and home equity loans. It does not apply to the mortgage used to purchase your home in the first place. During those three days, you can walk away at no cost.
Limits on Prepayment Penalties
Paying a loan off early sounds like it should always be welcome, but some loan agreements charge a prepayment penalty for exactly that. Federal rules have narrowed when such penalties can appear. FHA, VA, and USDA loans cannot carry them at all, and most conventional mortgages are similarly restricted.
Where a qualified mortgage does include a prepayment penalty, it cannot exceed 2% of the prepaid balance during the first two years and 1% during the third year. No penalty is allowed after the third year.13Consumer Financial Protection Bureau. Ability-to-Repay and Qualified Mortgage Rule High-cost mortgages are prohibited from including prepayment penalties at all.14eCFR. 12 CFR 1026.32 – Requirements for High-Cost Mortgages A lender that offers a loan with a prepayment penalty must also offer you an alternative loan without one.
Acceleration Clauses
Most loan agreements contain an acceleration clause, and it’s worth knowing about before you need it. The clause lets the lender demand immediate repayment of the entire remaining balance if you default or violate a specific term. Rather than collecting late fees on a missed payment, the lender can declare the full debt due at once. In practice, lenders usually send a notice of default first and give you a window to cure the problem. If you can’t cure it, the full remaining balance plus accumulated interest and fees comes due together.
Taxes on Borrowing
Money you borrow isn’t income. Because you’re obligated to pay it back, the IRS doesn’t treat loan proceeds as taxable, whether you take out a $5,000 personal loan or a $5 million business credit line. The tax implications of a loan product show up on the interest side, not the principal.
Homeowners who itemize can deduct mortgage interest on up to $750,000 of acquisition debt, or $375,000 if married filing separately.15Office of the Law Revision Counsel. 26 U.S. Code 163 – Interest That cap applies to mortgages taken out after December 15, 2017; older mortgages are grandfathered under the previous $1 million limit. HELOC and home equity loan interest is also deductible, but only when the borrowed funds are used to buy, build, or substantially improve the home securing the loan.
Businesses can generally deduct interest paid on loans used for business purposes, subject to a significant limit under Section 163(j). For most businesses, deductible business interest in a given year can’t exceed business interest income plus 30% of adjusted taxable income.16Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense For tax years beginning after 2024, adjusted taxable income allows an add-back for depreciation, amortization, and depletion, which is more favorable for capital-intensive businesses.17Internal Revenue Service. Instructions for Form 8990 (Rev. December 2025) Small businesses that meet a gross receipts test are exempt from the limit entirely.
If a lender forgives or cancels part of a loan, the forgiven amount generally becomes taxable income. This comes up in debt settlement, foreclosure, and modification scenarios where the lender writes off part of what you owe. Exceptions exist for insolvency and certain qualified principal residence debt, but the default rule is that canceled debt triggers a tax bill.
