What a bank examines before lending you money
A bank will lend you money if it believes you will pay it back. That belief rests on three things: your history of repaying debt, your current income, and the collateral you offer as insurance. The bank does not care why you need the money — it cares whether you are a safe bet.
Your credit score is a number between 300 and 850 that summarizes your repayment history. It rises when you pay bills on time and falls when you miss payments or carry high balances. Most banks will not lend to someone below a score of 620, though the exact threshold varies by lender and loan type. You can see your own score free once per year at annualcreditreport.com, which is the only site the federal government endorses for this purpose.
Your income must be large enough that the monthly loan payment does not consume too much of what you earn. Most lenders use a debt-to-income ratio: they add up all your monthly debt payments (car loans, credit cards, student loans, the new loan you are seeking) and divide by your gross monthly income. If that number exceeds 43 percent, most lenders will decline you. Some will go higher; some will not.
Your collateral is an asset the bank can seize if you stop paying. A car loan is secured by the car itself. A mortgage is secured by the house. An unsecured personal loan has no collateral, which is why the interest rate is higher — the bank has more to lose. If you have collateral to offer, you may may have access to for a lower rate or borrow more than your income alone would support.
Key Takeaways
- Banks examine your credit score, income, and existing debts before deciding whether to lend and at what interest rate.
- A credit score below 620 will disqualify you at most banks, though some credit unions and online lenders have lower thresholds.
- Your monthly debt payments cannot typically exceed 43 percent of your gross monthly income, though this varies by lender.
- Secured loans (backed by collateral like a car or house) carry lower interest rates than unsecured personal loans because the bank's risk is lower.
- The interest rate you receive depends on your credit score, income stability, and the type of loan — not on the lender's goodwill.
Where to look for a loan and what each type offers
Banks, credit unions, and online lenders all make loans, and each has different requirements and speed. A traditional bank (Chase, Bank of America, Wells Fargo) will move slowly but may offer lower rates if you already have an account there. A credit union is a member-owned nonprofit that often lends to people with lower credit scores and charges lower interest rates overall, but you must be a member to borrow. Online lenders (SoFi, LendingClub, Upstart) move faster — sometimes in hours — but charge higher rates because they take on more risk.
A personal loan is unsecured money you can use for anything. You repay it in fixed monthly installments over a set period, usually two to seven years. Interest rates range from 6 percent to 36 percent depending on your credit score and the lender. The better your credit, the lower your rate.
A secured personal loan requires collateral — often a savings account or a vehicle you own outright. The interest rate is lower because the lender's risk is lower. If you do not pay, the lender takes the collateral. These loans move faster because the bank's decision is simpler: does the collateral cover the loan amount?
A car loan is secured by the vehicle itself. The bank holds the title until you pay off the loan. Interest rates are lower than personal loans because the collateral is clear and valuable. Most car loans run three to six years.
A mortgage is a long-term secured loan for a house, usually 15 or 30 years. The interest rate is lower than any other loan type because the collateral (the house) is large and stable. Mortgages require a down payment, usually 3 to 20 percent of the purchase price, and a much more detailed financial review than other loans.
The steps from process to money in your account
The timeline depends on the lender type. An online personal loan can move from process to funding in one to three business days. A bank personal loan takes five to ten business days. A mortgage takes 30 to 45 days. A car loan depends on whether you are buying from a dealer (who may have financing ready) or from a private seller (where you must arrange the loan separately).
First, you will complete an process — online, by phone, or in person. You will provide your name, address, Social Security number, employment history, income, and existing debts. The lender will pull your credit report and score. This is called a hard inquiry and it temporarily lowers your credit score by a few points. Multiple hard inquiries within 14 days usually count as one, so shopping around for rates in a short window does not compound the damage.
Second, the lender will verify your income. For a salaried employee, this means a recent pay stub and possibly a letter from your employer. For self-employed people, it means tax returns, usually the last two years. For someone on disability or Social Security, it means a benefit statement. The lender wants proof that the income you claimed is real and stable.
Third, the lender will make a decision: approve, decline, or approve with conditions. Conditions might mean a lower loan amount, a higher interest rate, or a requirement to add a co-signer (someone who promises to pay if you do not). If you are approved, you will receive a loan agreement that spells out the interest rate, monthly payment, and repayment term. Read this carefully — the rate and terms should match what you were quoted.
Fourth, you will sign the agreement and the lender will fund the loan. For a personal loan, the money goes to your bank account. For a car loan, it goes to the dealer or seller. For a mortgage, it goes to the title company or escrow agent. You then begin making monthly payments on the date specified in the agreement.
How interest rates are set and what affects yours
The interest rate you receive is not negotiable in the way a car price is. It is calculated by a formula that weighs your credit score, income, loan amount, loan term, and the type of collateral (if any). A person with a 750 credit score will receive a lower rate than a person with a 650 score, even at the same lender, because the formula reflects the statistical likelihood that each will repay.
The prime rate is set by the Federal Reserve and influences all other interest rates in the economy. When the Fed raises the prime rate, lenders raise their rates too. When the Fed lowers it, lenders lower theirs. You cannot control the prime rate, but you can control your credit score and the loan term you choose.
Choosing a shorter loan term (three years instead of five) means a higher monthly payment but lower total interest paid. Choosing a longer term means a lower monthly payment but higher total interest. The lender will show you both options and the total cost of each before you sign.
Some lenders offer a rate discount if you set up automatic payments from a bank account, usually 0.25 to 0.5 percent off. Some offer a discount if you are already a customer. These small discounts add up over the life of a loan, so ask about them before you commit.
What to do if your process is declined
A decline does not mean you cannot borrow. It means that particular lender decided the risk was too high. The reasons are usually one of three: your credit score is too low, your debt-to-income ratio is too high, or your income cannot be verified.
If your credit score is the problem, you have two paths. You can wait and rebuild your score by paying all bills on time for several months, then reapply. Or you can look for lenders that work with lower scores — credit unions, online lenders, and some banks have different thresholds. Expect to pay a higher interest rate, but you can borrow.
If your debt-to-income ratio is too high, you can either pay down existing debt before reapplying or look for a smaller loan amount. Paying down a credit card balance by a few thousand dollars can lower your ratio enough to may have access to. Some lenders will also approve you if you add a co-signer with better income or credit.
If your income cannot be verified, gather better documentation. A recent tax return, a letter from your employer on company letterhead, or a bank statement showing regular deposits all help. If you are self-employed, two years of tax returns are standard. If you are on disability or Social Security, a benefit statement from the Social Security Administration works.
The difference between a co-signer and a co-borrower
A co-signer promises to pay the loan if you do not, but does not receive the money and has no claim to it. The co-signer's credit and income are reviewed, and their agreement strengthens your process. If you pay on time, the co-signer is never contacted. If you miss a payment, the lender can pursue the co-signer for the full amount. A co-signer's credit score is also affected by the loan — late payments hurt them too.
A co-borrower is different: both of you receive the money, both are responsible for repayment, and both own whatever is purchased. A mortgage often has two co-borrowers (spouses, for example). A personal loan rarely does. Co-borrowers are treated equally by the lender; a co-signer is a backup.
Adding a co-signer can lower your interest rate and increase the amount you can borrow, but it puts that person at real financial risk. They should understand this before they agree. If you default, it damages their credit and the lender can pursue them for payment.
Frequently Asked Questions
What is the difference between APR and interest rate?
The interest rate is the percentage of the loan amount charged per year. The APR (annual percentage rate) includes the interest rate plus fees the lender charges, expressed as a yearly rate. The APR is always equal to or higher than the interest rate. Lenders must disclose both, and you should compare APRs when shopping for loans, not just interest rates.
Can I get a loan with no credit history?
Yes, but it is harder. Credit unions and some online lenders will lend to people with no credit score, though the interest rate will be higher. You may need a co-signer or collateral. Building credit takes time — a secured credit card (backed by a cash deposit) is one way to start, and after six months of on-time payments, you will have a credit score.
What happens if I pay off my loan early?
You will pay less interest overall, which saves money. Some lenders charge a prepayment penalty for this, but federal law prohibits prepayment penalties on mortgages and most car loans. Check your loan agreement to see if a penalty applies. If it does not, paying extra toward principal each month or making a lump-sum payment when you can will reduce the total cost.
How much should I borrow?
Borrow only what you need and can afford to repay. A larger loan means higher monthly payments and more interest paid over time. Use a loan calculator (most lenders have one on their website) to see what different loan amounts cost per month, then choose the amount that fits your budget comfortably, not the maximum the lender will offer.
Does explore for a loan hurt my credit score?
A hard inquiry lowers your score by a few points temporarily. Multiple inquiries within 14 days usually count as one, so shopping around for rates in a short window minimizes the damage. The score recovers within a few months. Once you take out the loan, making on-time payments will rebuild and improve your score over time.
