A bank loan is money the bank lends you, with the understanding that you'll pay it back over time with interest.

When you borrow from a bank, you receive a lump sum of cash upfront. The bank expects you to repay that amount in regular installments—usually monthly—plus a percentage charge called interest. The interest is how the bank makes money on the loan. The total amount you borrowed is called the principal.

The bank doesn't hand you cash and trust you'll pay it back. They assess whether you can actually repay it by looking at your credit history, income, and existing debts. If they think the risk is too high, they say no. If they approve you, they'll set terms: how much you can borrow, what interest rate you'll pay, and how long you have to repay it.

Unlike a credit card, where you can borrow up to a limit and pay back as much or as little as you want each month, a bank loan has a fixed repayment schedule. You know exactly what your payment will be each month and when the loan will be paid off.

Key Takeaways

  • A bank loan gives you a set amount of money upfront that you repay in fixed monthly payments over a set period, usually two to seven years.
  • Interest is the cost of borrowing—the bank charges you a percentage of the loan amount, and the rate depends on your credit score, income, and the type of loan.
  • Banks check your credit history and income before approving a loan, and they may require collateral (like a car or house) to find the debt.
  • Personal loans are unsecured (no collateral required), while auto loans and mortgages are secured by the asset you're buying.
  • The longer your repayment period, the more interest you'll pay overall, even if your monthly payment is smaller.

How interest rates are set and what affects yours

The interest rate a bank offers you depends on several factors. Your credit score—a three-digit number that reflects your history of paying debts on time—is the biggest one. A higher credit score means lower risk to the bank, so you get a lower rate. A lower score means a higher rate.

The type of loan also matters. A mortgage (a loan to buy a house) typically has a lower rate than a personal loan, because the house itself serves as collateral—if you don't pay, the bank can take it. An auto loan falls in the middle. Personal loans, where the bank has no collateral, carry higher rates.

The length of the loan affects the rate too. A three-year loan usually has a lower rate than a seven-year loan for the same amount, because the bank's money is at risk for a shorter time. Current economic conditions and the Federal Reserve's interest rate also influence what banks charge.

You won't know your exact rate until you explore. Banks will often give you a range—"between 6% and 12%"—and then tell you the specific rate after they pull your credit report and verify your income.

Secured loans versus unsecured loans

A secured loan is backed by something of value that you own or are buying. An auto loan is secured by the car itself. A mortgage is secured by the house. If you stop paying, the bank can repossess the car or foreclose on the house. Because the bank has this safety net, they charge lower interest rates on secured loans.

An unsecured loan has no collateral. A personal loan is unsecured—the bank is lending you money based only on your promise to repay and your credit history. If you default, the bank can't take your car or house. They can sue you or send the debt to a collection agency, but they have no asset to seize. Because of this higher risk, unsecured loans carry higher interest rates.

Some people use their home as collateral for an unsecured personal loan, turning it into a secured loan and lowering the rate. This is called a home equity loan or home equity line of credit. It's a way to borrow at a lower rate, but it puts your house at risk if you can't repay.

What happens during the loan approval process

When you explore for a bank loan, the bank pulls your credit report from one of the three major credit bureaus (Equifax, Experian, or TransUnion). They look at your payment history, how much debt you already carry, and how long you've had credit accounts open. They also verify your income by asking for recent pay stubs or tax returns.

The bank calculates your debt-to-income ratio—the percentage of your monthly income that goes toward debt payments. If you earn $5,000 a month and already pay $1,500 toward car loans, credit cards, and student loans, your ratio is 30%. Most banks want this ratio below 43%, though some will go higher for mortgages.

The approval process usually takes three to seven business days for personal loans and auto loans. Mortgages take longer—typically 30 to 45 days—because the bank orders a property appraisal and title search. If the bank approves you, they'll send you a loan agreement that spells out the interest rate, monthly payment, repayment period, and any fees.

Read this agreement carefully before signing. Look for the annual percentage rate (APR), which includes both the interest rate and any fees the bank charges. The APR is the true cost of borrowing and is what you should compare between lenders.

Monthly payments and how long loans last

Your monthly payment depends on three things: how much you borrowed, the interest rate, and how long you have to repay it. A $20,000 personal loan at 8% interest costs you about $467 per month over five years, or about $333 per month over seven years. The longer the loan, the lower your monthly payment—but you'll pay more interest overall.

Most personal loans last two to seven years. Auto loans typically last three to six years. Mortgages last 15 to 30 years. The longer the loan term, the more interest you'll pay. On that $20,000 personal loan at 8%, you'd pay about $2,000 in interest over five years but about $3,300 over seven years.

Your monthly payment is fixed—it stays the same every month until the loan is paid off. This is different from a credit card, where your payment can change based on how much you owe. With a fixed payment, you know exactly what to budget for.

Some loans allow you to pay off the balance early without a penalty. Others charge a prepayment penalty—a fee for paying off the loan ahead of schedule. Ask about this before you sign. If you think you might come into money and want to pay the loan off early, you want a loan with no prepayment penalty.

Fees and hidden costs to watch for

Beyond interest, banks charge fees on loans. An origination fee is a one-time charge for processing the loan, usually 1% to 5% of the loan amount. A prepayment penalty charges you for paying off the loan early. Some loans have late fees if you miss a payment. A few have annual fees, though these are less common on personal and auto loans.

The bank may also require you to pay for an appraisal (on mortgages), a credit report, or title insurance (on auto loans). These costs are sometimes rolled into the loan, meaning you borrow extra money to cover them. Other times you pay them upfront.

The loan agreement will list all fees. The APR (annual percentage rate) is supposed to include most of them, so comparing APRs between lenders is a good way to see the true cost. But read the fine print anyway—some fees may not be included in the APR calculation.

What to do if you can't make a payment

If you miss a payment, the bank will contact you. Most banks give you a grace period of 10 to 15 days before they charge a late fee. If you're going to miss a payment, call the bank before the due date. Many will work with you on a temporary payment plan or let you defer a payment to the end of the loan.

If you miss multiple payments, the bank may declare the loan in default and demand full repayment when ready. They can then sue you, garnish your wages, or send the debt to a collection agency. On a secured loan like an auto loan or mortgage, they can repossess the car or foreclose on the house.

If you're struggling with loan payments, contact your bank's loss mitigation department before you fall behind. They have options—loan modification, forbearance, or deferment—that can lower your payment temporarily or extend the loan term. These options are easier to get before you default than after.

Frequently Asked Questions

What's the difference between a bank loan and a credit card?

A bank loan gives you a fixed amount upfront and requires fixed monthly payments over a set period. A credit card gives you a credit limit and lets you borrow as much as you want up to that limit, paying back as little as you choose each month (as long as you pay the minimum). Credit cards have higher interest rates and are meant for short-term borrowing.

Can I get a bank loan with bad credit?

Yes, but you'll pay a higher interest rate. Some banks specialize in loans for people with credit scores below 620. You might also find better rates at a credit union if you're a member. Another option is to add a co-signer with better credit, though they become legally responsible for the debt if you don't pay.

What happens if I pay off a loan early?

You'll save money on interest. However, some loans charge a prepayment penalty—a fee for paying off early. Check your loan agreement before you sign to see if there's a penalty. If there isn't, paying extra toward principal each month or making a lump-sum payment when you can will reduce the total interest you pay.

How much can I borrow?

The amount depends on your income, credit score, and existing debts. Most banks will lend you up to 10 to 15 times your monthly income, but your debt-to-income ratio has to stay below their limit (usually 43%). For a mortgage, you can typically borrow up to 80% of the home's value, sometimes more if you have excellent credit.

Is it better to borrow from a bank or a credit union?

Credit unions often charge lower interest rates and fees than banks, especially if you have average or below-average credit. However, you have to be a member to borrow. Banks are more widely available and often have faster approval processes. Compare rates from both before you decide.
