Interest rates affect the money you earn in a savings account and the amount you pay on a mortgage, credit card, auto loan, or personal loan. However, the rate announced by the Federal Reserve is not the same rate a bank offers an individual customer. Checked July 24, 2026, this guide explains how the main types of U.S. interest rates connect.
An interest rate is the price of using money, usually shown as a percentage of the amount deposited or borrowed. Savings rates and loan rates differ because banks must account for funding costs, operating expenses, repayment risk, loan terms, and profit. Your actual rate may also depend on fees, compounding, credit history, and account conditions.
What Is an Interest Rate?
Interest is the dollar amount earned or charged. The interest rate is the percentage used to calculate that amount.
For example, suppose you deposit $1,000 for one year at a simple annual interest rate of 5%. The estimated interest would be $50 before taxes. This is only a basic example. Actual earnings may differ when interest compounds daily or monthly, the rate changes, fees apply, or money is withdrawn during the year.
For borrowers, interest is part of the cost of receiving money now and repaying it later. A lender considers how long the money will be unavailable, the possibility that it will not be repaid, and the cost of obtaining the funds used to make the loan.
Interest Rate, APY, and APR Are Not the Same
U.S. consumers commonly see three related terms. The correct number to compare depends on whether you are depositing or borrowing money.
| Term | Common use | What it shows |
|---|---|---|
| Interest rate | Deposits and loans | The percentage used to calculate interest |
| APY | Savings accounts and CDs | Estimated annual earnings after accounting for compounding |
| APR | Loans and credit cards | An annual measure of borrowing cost that may include certain fees |
Annual percentage yield, or APY, reflects the total interest an account can earn based on its interest rate and compounding frequency. This makes APY more useful than the stated interest rate when comparing deposit accounts with different compounding schedules. Account fees, balance requirements, and CD withdrawal penalties still need to be reviewed separately.
Annual percentage rate, or APR, is generally used for borrowing. The Consumer Financial Protection Bureau explains that a loan’s interest rate is the cost charged for borrowing, while APR is a broader measure that includes the rate and certain additional loan fees. The exact costs included can depend on the credit product.
Why Are Savings Rates Lower Than Loan Rates?
When you place money in a savings account or certificate of deposit, the financial institution can use deposits as one source of funding. The interest paid to you is a cost to the institution.
When the institution makes a loan, it generally charges more than its funding cost. The difference helps cover employee and technology expenses, regulatory costs, potential loan losses, required capital, and profit.
Loan rates also vary because borrowers do not present the same repayment risk. Depending on the product, pricing may reflect credit history, income, debt, collateral, loan size, repayment period, and whether the rate is fixed or variable. A secured mortgage and an unsecured credit card balance therefore should not be expected to carry the same rate.
How Does the Federal Reserve Affect Consumer Rates?
The Federal Reserve does not directly set the APY on your savings account or the APR on your mortgage. The Federal Open Market Committee sets a target range for the federal funds rate, which is associated with overnight lending between depository institutions. Changes in monetary policy can influence other short-term market rates and broader funding conditions.
The FOMC has eight regularly scheduled meetings each year, although additional meetings can be held when needed. A policy decision may influence financial markets quickly, but consumer rates do not have to change on the same day or by the same percentage.
Each institution makes its own pricing decisions based on market rates, deposit demand, competition, loan demand, risk, and its current funding needs. This is why two banks can offer different savings APYs or loan APRs under the same Federal Reserve policy.
Fixed and Variable Rates React Differently
A fixed rate is intended to remain unchanged for the period described in the agreement. An existing fixed-rate CD may continue paying its contracted rate until maturity. A fixed-rate installment loan may also keep the same rate even when market rates change.
A variable rate is connected to an index or another rate described in the contract. The CFPB states that a variable APR changes with its index, while a fixed APR does not fluctuate automatically with index changes. However, “fixed” does not always mean the rate can never change. The agreement and applicable notice rules determine when an issuer may make a change.
What Should You Compare?
For a savings account or CD
- Compare APY rather than promotional wording alone.
- Check whether the rate is fixed, variable, promotional, or limited to certain balances.
- Review minimum-balance requirements and monthly fees.
- For a CD, review the term, maturity instructions, and early withdrawal penalty.
- Confirm that the institution and account ownership category qualify for applicable deposit insurance.
For a loan or credit card
- Compare APR as well as the stated interest rate.
- Check whether the rate is fixed or variable and identify the index for a variable rate.
- Review origination fees, closing costs, annual fees, and other charges.
- Compare the repayment term and total estimated payments, not only the monthly payment.
- Confirm when a promotional rate ends and what rate may apply afterward.
The Bottom Line
An interest rate is the price paid for borrowing money or the return received for depositing it. Savings rates, loan rates, and Federal Reserve policy rates serve different purposes and should not be treated as interchangeable numbers.
When saving, compare APY, fees, balance rules, and withdrawal restrictions. When borrowing, compare APR, loan fees, repayment terms, and fixed or variable rate conditions. The rate advertised in the news or on a lender’s website may not be the rate ultimately offered to you, so review the official account disclosure or loan documents before making a decision.
