A loan product is a packaged borrowing arrangement offered by a bank, credit union, or other lender, defined by a specific set of terms for how much you can borrow, how you’ll pay it back, what it costs, and what happens if you don’t. Every loan product, whether it’s a 30-year mortgage or a business line of credit, is a contract with the same skeleton: the lender advances you money, and you agree to return it on a schedule with interest. The differences between products come down to how those terms are set and what protections attach to them.
The Four Building Blocks of Any Loan
Strip away the marketing and every loan product reduces to four elements.
The principal is the amount you actually borrow. Each payment you make reduces this balance, though not always by as much as you’d think early on.
The interest rate is what the lender charges for the use of that money. Most lenders quote it as an Annual Percentage Rate, or APR. Federal rules require the APR to be disclosed as “the cost of your credit as a yearly rate,” and it includes not only interest but certain mandatory fees rolled into the loan.1eCFR. 12 CFR 1026.18 – Content of Disclosures When you’re comparing offers, APR tells you more than the raw interest rate does.
The loan 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. Longer terms mean smaller monthly payments but more total interest paid over the life of the loan.
The collateral is the asset, if any, that secures the loan. A mortgage is secured by the home; an auto loan by the car. If you stop paying, the lender can seize the pledged asset. Because that reduces the lender’s risk, secured loans almost always carry lower interest rates than unsecured ones.
Fixed Rates or Variable Rates
The first real choice most borrowers face is whether the interest rate stays put or moves over time. A fixed-rate loan holds your rate steady for the full term. Your payment doesn’t change. Most conventional mortgages, auto loans, and personal loans work this way.
A variable-rate loan starts at one rate and recalculates periodically against a market benchmark. The dominant U.S. dollar benchmark today is the Secured Overnight Financing Rate, or SOFR, which reflects the cost of overnight borrowing backed by Treasury securities.2Federal Reserve Bank of New York. Transition from LIBOR Your lender adds a fixed margin on top of the index. If SOFR is 4% and your margin is 2.5%, you pay 6.5% until the next adjustment.
Adjustable-rate mortgages show how this plays out. A “5/6m ARM” locks your initial rate for five years, then resets every six months.3Consumer Financial Protection Bureau. Adjustable Rate Mortgages These products include rate caps that limit how much the rate can move at each adjustment and over the full term. Variable-rate loans can save you money if rates fall, but they also expose you to payment increases you can’t forecast years out.
Secured or Unsecured, Term or Revolving
Beyond the rate, lenders sort loan products along two other axes.
A secured loan is tied to a specific asset the lender can claim if you default. Mortgages and auto loans are the classic examples. An unsecured loan rests only on your credit and income, so there’s nothing to repossess if you stop paying. Most credit cards and many personal loans are unsecured, which is why their rates run higher.
A term loan gives you one lump sum and a fixed schedule to pay it off. Each payment reduces the balance according to an amortization schedule, and the loan ends when the balance hits zero. A revolving credit facility does the opposite: the lender sets a credit limit, and you can borrow, repay, and re-borrow up to that limit for as long as the account stays open. You pay interest only on what you’ve actually drawn. Credit cards and business lines of credit are the most common revolving products.
Consumer Loan Products
Mortgages
A mortgage is the largest loan most people ever take on. You borrow to buy residential property, and the property secures the debt. Most borrowers pick a 15- or 30-year term. One quirk trips people up: in the early years, most of each payment goes toward interest, and principal reduction accelerates later. Extra payments made early can shave years off the loan.
A home equity line of credit, or HELOC, lets you borrow against equity you’ve already built. It’s a revolving product with a draw period during which you can pull funds, followed by a repayment period that typically runs 10 to 15 years.4Consumer Financial Protection Bureau. What You Should Know About Home Equity Lines of Credit HELOCs almost always carry variable rates, so payments can move.
Auto Loans
Auto loans are secured term loans, with the vehicle serving as collateral. The lender’s claim sits on the title, and if you default, the car can be repossessed. In many states, repossession can happen as soon as you miss a payment, depending on how your contract defines default.5Federal Trade Commission. Vehicle Repossession Terms usually run three to seven years.
Personal Loans
Personal loans are lump-sum term loans, secured or unsecured. Because the funds aren’t tied to a specific purchase, borrowers commonly use them to consolidate higher-rate debt or handle a large unexpected expense. An unsecured personal loan is approved mostly on your credit score and debt-to-income ratio. Secured versions may accept a certificate of deposit or investment account as collateral, which usually brings the rate down.
Student Loans
Federal student loans are one of the few products where the government is the direct 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 the start. For the 2025–2026 academic year, the fixed rate on undergraduate Direct Loans is 6.39%, graduate Direct Unsubsidized Loans carry 7.94%, and Direct PLUS Loans for parents and graduate students sit at 8.94%.6Federal Student Aid. Interest Rates and Fees for Federal Student Loans Private student loans from banks and credit unions exist too, but they lack the income-driven repayment plans and forgiveness options that come with federal loans.
Business Loan Products
Term Loans and Lines of Credit
A business term loan mirrors its consumer counterpart. The business takes a lump sum and repays it on a fixed schedule. These are usually the vehicle for large capital investments where the full amount is needed upfront.
A business line of credit is the revolving alternative. It gives the business access to a set limit that can be drawn on for inventory, seasonal cash gaps, or other short-term needs. Interest applies only to the amount actually drawn. 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 way of channeling capital to small businesses. These are not government loans in the literal sense. A private bank or credit union makes the loan, and the SBA guarantees a portion, which makes lenders willing to extend credit to smaller or less-established firms.7U.S. Small Business Administration. 7(a) Loans The guarantee ranges from 50% for SBA Express loans up to 90% for certain export loans of $350,000 or less.8U.S. Small Business Administration. Types of 7(a) Loans
The maximum loan under the standard 7(a) program is $5 million, and funds can go toward real estate, equipment, working capital, and business acquisitions, among other uses.7U.S. Small Business Administration. 7(a) Loans Rates are negotiated between borrower and lender but capped by SBA maximums tied to the prime rate or an optional peg rate plus a spread. For loans over $350,000, the rate cannot exceed the base rate plus 3%.9U.S. Small Business Administration. Terms, Conditions, and Eligibility
Fees Beyond Interest
The rate isn’t the whole cost of a loan. Most products carry additional charges.
An origination fee covers the lender’s cost to process your application and set up the loan. On mortgages, this typically runs 0.5% to 1% of the loan amount. Some lenders split it into “processing” and “underwriting” line items, but the money goes to the same place.
Mortgages add closing costs: recording fees, title insurance, appraisal charges, and potential mortgage taxes that vary by location. Federal law requires the lender to give you a Loan Estimate within three business days of your application so you can compare total costs before committing.
Business loans secured by specific assets often involve filing fees to register the lender’s security interest with the state. These are usually modest but add to upfront costs. Some revolving credit products also charge annual maintenance fees or inactivity fees if the line goes unused.
Protections the Law Gives Borrowers
Adverse Action Notices
If a lender denies your application, it has to tell you why. Under the Equal Credit Opportunity Act and the Fair Credit Reporting Act, the lender must send an adverse action notice with the specific reasons for the denial, and if a credit score played a role, the key factors that hurt your score. You generally receive this notice within 30 days of the completed application. It often reveals fixable problems, like a credit report error, that you’d otherwise never see.
Right of Rescission on Home Loans
For certain mortgage transactions that put a security interest on your primary home, federal law gives you a three-day cooling-off period. 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.10Consumer 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 you use to purchase a home in the first place.
Limits on Prepayment Penalties
Paying a loan off early sounds like it should always be a win, but some agreements charge a prepayment penalty for doing exactly that. Federal rules have narrowed when these penalties can apply. FHA, VA, and USDA loans cannot include them at all.
For qualified mortgages that do include a prepayment penalty, the penalty 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.11Consumer Financial Protection Bureau. Ability-to-Repay and Qualified Mortgage Rule High-cost mortgages cannot include prepayment penalties at all.12eCFR. 12 CFR 1026.32 – Requirements for High-Cost Mortgages If a lender wants to offer a loan with a prepayment penalty, it must also offer you an alternative loan without one.
Tax Treatment
Money you borrow isn’t income. Because you owe it back, the IRS doesn’t tax loan proceeds. That holds for a $5,000 personal loan and a $5 million business credit line alike. The tax action is on the interest side.
Homeowners who itemize can deduct mortgage interest on up to $750,000 of acquisition debt, or $375,000 if married filing separately.13Office 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 if the funds go toward buying, building, or substantially improving the home securing the loan.
Businesses can generally deduct interest on loans used for business purposes, subject to the Section 163(j) limitation. For most businesses, deductible interest expense in a year cannot exceed business interest income plus 30% of adjusted taxable income.14Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense For tax years beginning after 2024, the adjusted taxable income calculation adds back depreciation, amortization, and depletion, which helps capital-intensive businesses.15Internal Revenue Service. Instructions for Form 8990 (Rev. December 2025) Small businesses meeting a gross receipts test are exempt from the limitation.
If a lender forgives a loan balance, the forgiven amount generally becomes taxable income. This shows up in debt settlement, foreclosure, and loan modification scenarios where a 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.
