Banks don't have one interest rate—they set different rates for different products and customers
When you ask "what is the interest rate for banks," you're really asking which rate applies to you. A bank might offer 0.01% on a savings account, 4.5% on a mortgage, 8% on a personal loan, and 22% on a credit card—all at the same time. The rate you get depends on what product you're using, how creditworthy you are, how long you're borrowing for, and what the bank's costs are at that moment.
Banks don't set rates in isolation. They start with the federal funds rate—the interest rate the Federal Reserve sets for banks to lend to each other overnight. This rate influences everything else. When the Fed raises its rate, banks raise theirs. When the Fed cuts, banks eventually cut. But the relationship is not one-to-one, and banks add their own markup depending on the product and your risk profile.
The markup—called the spread or margin—is where the bank makes money. On a mortgage, the spread might be 1% to 3% above the Fed's benchmark. On a credit card, it can be 15% to 25% above that same benchmark. A customer with excellent credit gets a lower spread. A customer with poor credit gets a higher one, because the bank is taking on more risk that the loan won't be repaid.
Key Takeaways
- Banks set different rates for savings accounts, checking accounts, mortgages, auto loans, personal loans, and credit cards—you cannot compare them as one number.
- The federal funds rate, set by the Federal Reserve, is the foundation that influences all other bank rates, though banks add their own markup on top.
- Your credit score, income, employment history, and the size of your down payment all affect the rate you personally receive for the same product.
- Banks also adjust rates based on how long you borrow for—a 15-year mortgage rate differs from a 30-year rate at the same bank on the same day.
- Rates change constantly, so the rate you see advertised today may not be the rate you lock in tomorrow, and it will not be the rate someone else gets.
How the Federal Reserve's rate flows down to what you pay
The Federal Reserve does not set the rate you pay on a mortgage or credit card. It sets the federal funds rate—the rate at which banks lend reserve balances to each other overnight. This rate is currently set in a range (for example, 4.25% to 4.50%), and it changes roughly eight times per year when the Fed's policy committee meets.
Banks use this rate as a reference point. When the Fed raises the federal funds rate, banks know their own borrowing costs are going up, so they raise the rates they charge customers. When the Fed cuts, banks eventually cut customer rates too—though they often cut faster than they raise. The delay between a Fed move and a bank rate change can be days, weeks, or months depending on the product and the bank's strategy.
Beyond the federal funds rate, banks also watch the prime rate, which is the rate banks charge their most creditworthy customers for short-term loans. The prime rate is directly tied to the federal funds rate and moves in lockstep. Many credit cards and adjustable-rate mortgages are pegged to the prime rate, so when the prime rate moves, your rate moves with it.
Why your rate is different from the advertised rate
Banks advertise a range of rates because they do not give the same rate to everyone. The rate you receive depends on your credit score, which is a three-digit number that reflects your history of borrowing and repaying. A score of 750 or higher typically qualifies you for the lowest advertised rate. A score of 650 to 700 might get you a rate 1% to 2% higher. A score below 620 might get you 3% to 5% higher, or you might not be approved at all.
Your debt-to-income ratio also matters. This is the percentage of your monthly income that goes toward debt payments. If you earn $5,000 per month and already owe $1,500 per month on other loans, your ratio is 30%. Most banks want this ratio below 43% for a mortgage. If yours is higher, the bank sees you as riskier and charges a higher rate or denies you.
The loan term—how long you have to repay—affects your rate too. A 15-year mortgage rate is usually lower than a 30-year rate at the same bank on the same day, because the bank's money is at risk for a shorter time. A 3-month certificate of deposit (CD) pays less than a 5-year CD. The longer the bank lends, the more it charges.
Your down payment or collateral also changes the rate. If you put 20% down on a house, you get a better rate than if you put 5% down, because the bank's risk is lower. If you borrow against a savings account or CD, you get a better rate than an unsecured personal loan, because the bank can seize the collateral if you don't pay.
How banks decide their markup on top of the federal rate
Once the Fed sets its rate, banks decide how much extra to charge. This extra amount is the spread or margin. A bank might say: "The federal funds rate is 4.5%, so we'll charge 2% on top of that for a 30-year mortgage." That gives you a 6.5% rate. Another bank might charge only 1.5% on top, offering 6%. The difference comes down to the bank's own costs and strategy.
A bank's costs include the interest it pays depositors (the rate on your savings account), the cost of running branches and customer service, loan losses from customers who default, and regulatory requirements. A bank that pays high rates on savings accounts has to charge higher rates on loans to make up the difference. A bank with expensive physical branches might charge more than an online-only bank with lower overhead.
Banks also adjust spreads based on market conditions. When loan demand is high and competition is low, banks widen their spreads and charge more. When many banks are competing for the same customers, spreads narrow and rates drop. This is why shopping around matters—the same loan at different banks can have rates that differ by 0.5% to 1%, which translates to thousands of dollars over the life of the loan.
Rates for different products at the same bank
A single bank sets different rates for different products because each product carries different risk and cost. Here is how they typically compare:
| Product | Typical Spread Above Fed Rate | Why the Spread Varies |
|---|---|---|
| Savings Account | 0% to 2% below Fed rate | Banks pay depositors less than they charge borrowers; savings is the bank's source of funds. |
| Money Market Account | 0.5% to 2% below Fed rate | Slightly higher than savings because it requires a larger balance and has withdrawal limits. |
| Certificate of Deposit (CD) | 0.5% to 3% below Fed rate | Longer terms pay more because the bank locks in your money; you cannot withdraw early without penalty. |
| Mortgage (30-year) | 1.5% to 3% above Fed rate | Long-term risk; the bank's money is tied up for decades and interest rates could rise. |
| Auto Loan (5-year) | 2% to 5% above Fed rate | Shorter term than mortgage but higher risk; the car depreciates and can be repossessed. |
| Personal Loan (unsecured) | 5% to 12% above Fed rate | No collateral; the bank has nothing to seize if you don't pay, so it charges more. |
| Credit Card | 15% to 25% above Fed rate | Highest risk; revolving credit, high default rates, and the bank must process thousands of small transactions. |
These spreads are not fixed. They change based on the bank's strategy, the economy, and competition. During a recession, spreads widen because banks expect more defaults. During strong economic growth, spreads narrow because banks compete harder for customers.
How to find the current rates banks are offering
Bank rates change daily, sometimes multiple times per day. The rate you see on a bank's website this morning might be different by this afternoon. To find current rates, check the bank's website directly—most banks list their current rates for savings accounts, CDs, mortgages, and loans on their homepage or in a rates section.
For mortgages and auto loans, you can compare rates across multiple banks using sites that aggregate current offers. These sites do not set rates; they show you what banks are currently advertising. Keep in mind that the rate you see is the best rate the bank offers—you may not may have access to for it if your credit score or income is below the bank's threshold.
When you apply for a loan, the bank will give you a Loan Estimate (for mortgages) or a Truth in Lending disclosure (for other loans). This document shows the exact rate, fees, and terms you may have access to for. The rate on this document is what you will actually pay, assuming you lock it in before applying. If you wait, rates may move and your locked rate may change.
What happens when the Fed changes its rate
When the Federal Reserve raises or lowers its rate, the effects ripple through the banking system, but not instantly and not equally. Savings account rates and CD rates usually move quickly—often within days—because banks compete for deposits and want to attract savers. If the Fed cuts rates, banks cut savings rates fast to keep their costs down.
Mortgage rates move more slowly and less predictably. Mortgage rates are influenced by the Fed's rate, but they also track the 10-year Treasury bond yield, which is set by the bond market, not the Fed. When the Fed raises rates, the Treasury yield usually rises too, but not always by the same amount. A Fed rate hike might push mortgage rates up by 0.25%, or by 0.5%, or by nothing at all, depending on what the bond market does.
Credit card rates and adjustable-rate mortgage rates move in lockstep with the prime rate. When the Fed raises its rate, the prime rate rises immediately, and credit card rates follow within one or two billing cycles. If you have a variable-rate mortgage or home equity line of credit (HELOC), your rate will adjust on the date specified in your contract—usually annually or semi-annually.
Auto loan rates and personal loan rates adjust gradually. Banks do not change rates on existing loans, but they change the rates they offer to new borrowers. If you locked in a 5% auto loan last month and the Fed raises rates this month, your rate stays at 5%. New borrowers will see higher rates.
Frequently Asked Questions
Do all banks charge the same interest rate?
No. Banks set their own rates based on their costs, strategy, and competition. The same mortgage product can have rates ranging from 6% to 6.75% across different banks on the same day. Shopping around can save you thousands of dollars over the life of a loan.
Why is my credit card rate so much higher than my mortgage rate?
Credit cards are unsecured debt—the bank has no collateral to seize if you don't pay. Mortgages are secured by the house itself. Unsecured debt carries higher risk, so banks charge more. Credit cards also have higher default rates and higher processing costs than mortgages.
Can I negotiate my interest rate with a bank?
For mortgages and auto loans, you can shop around and choose the bank offering the best rate for your credit profile. You cannot negotiate the rate itself, but you can negotiate fees or ask the bank to match a competitor's offer. For credit cards, your rate is set by the card issuer based on your creditworthiness and is not negotiable.
What is the difference between APR and interest rate?
The interest rate is the cost of borrowing expressed as a percentage. The APR (annual percentage rate) includes the interest rate plus fees, spread over a year. For mortgages and auto loans, APR is usually slightly higher than the interest rate. For credit cards, APR and interest rate are the same thing.
If the Fed cuts rates, will my mortgage rate go down?
Not automatically. Mortgage rates track the 10-year Treasury bond yield, not the Fed's rate directly. The Fed's rate influences the Treasury yield, but the relationship is loose. A Fed rate cut might lower mortgage rates, or it might not, depending on what the bond market expects about inflation and economic growth.
