People often see “rate” on a savings account, “interest rate” on a loan offer, and “interest” on a monthly statement. These terms are related, but they are not interchangeable. Understanding the difference can help you compare deposit accounts, credit cards, auto loans, and mortgages more accurately.
In U.S. finance, “rate” usually means “interest rate.” It is the percentage applied to the principal. “Interest” is the dollar amount earned or charged. APR and APY are related annual measures, but they are not simply alternative names for an interest rate.
What Does Interest Rate Mean?
An interest rate is the percentage used to calculate the cost of borrowing money or the return paid for keeping money in an interest-bearing account. The principal is the amount originally borrowed or deposited.
For a borrower, the interest rate helps determine how much the lender charges for using its money. For a saver, it helps determine how much a bank or credit union pays on the deposited balance.
Financial advertisements and conversations often shorten “interest rate” to “rate.” A statement such as “the rate is 5%” normally means the interest rate is 5%, as long as the surrounding context identifies the account or loan being discussed.
The Federal Reserve also uses the term interest rate when explaining the cost of borrowing and how changing rates can affect consumer and business decisions. Higher rates generally make borrowing more expensive, while lower rates generally reduce borrowing costs. The actual rate offered to an individual can still depend on the product, credit profile, loan term, and market conditions.
What Is Interest?
Interest is the actual amount of money earned or paid. It is usually shown in dollars rather than only as a percentage.
A savings statement may show that an account earned $12.48 in interest during the month. A loan statement may show that $140 of a payment went toward interest and the remaining amount went toward principal. In both cases, the interest rate helps calculate the amount, but the percentage and the dollar amount are not the same thing.
Example: $1,000 at a 5% Interest Rate
Assume you deposit $1,000 for one year at a simple annual interest rate of 5%.
$1,000 × 5% × 1 year = $50 of interest
- $1,000 is the principal.
- 5% is the interest rate.
- $50 is the interest earned.
This is a simplified example. Actual earnings can change based on compounding, the number of days the money remains in the account, balance requirements, withdrawals, and fees. The Consumer Financial Protection Bureau explains that compound interest allows a saver to earn interest on the original deposit and on interest already added to the account.
Interest Rate, APR, and APY Are Not the Same
Americans commonly see two other percentage terms: APR and APY. They should not automatically be treated as another name for the basic interest rate.
APR for Borrowing
APR means annual percentage rate. For many loans, APR is a broader measure than the stated interest rate because it generally reflects the interest rate and certain additional loan charges.
According to the CFPB’s explanation of interest rates and APR, the interest rate represents the cost charged for borrowing the principal, while APR may also include origination charges and other applicable fees.
When comparing loan offers, compare APR with APR rather than comparing one lender’s APR with another lender’s interest rate. For mortgages, APR may include points, mortgage broker fees, and certain other charges. However, APR does not make every loan difference disappear, especially when loan terms or adjustable-rate features are different.
APY for Savings
APY means annual percentage yield. It is commonly used for savings accounts, money market deposit accounts, and certificates of deposit.
APY reflects the interest rate and the effect of compounding over a year under standardized assumptions. A deposit account’s APY may therefore be slightly higher than its stated interest rate when interest compounds during the year.
The federal Annual Percentage Yield calculation rules explain that APY measures interest earned based on the interest rate and compounding frequency. When comparing deposit accounts, APY generally provides a more useful comparison than the stated interest rate alone.
Why the Same Rate Can Produce Different Interest
Two products can display the same interest rate but produce different dollar results. The outcome depends on more than the percentage.
For savings, the result can depend on the balance, compounding frequency, account term, variable-rate changes, fees, and withdrawals. A CD may also impose an early withdrawal penalty if money is removed before maturity.
For loans, the interest charged can depend on the remaining principal, payment timing, repayment term, amortization schedule, fees, and whether the rate is fixed or adjustable. A 5% loan rate does not necessarily mean the borrower pays 5% of the original balance every year throughout the entire loan.
What Should You Compare?
For a savings account or CD, review the following:
- APY and stated interest rate
- Whether the rate is fixed or variable
- Compounding frequency
- Minimum balance requirements
- Monthly account fees
- CD term and early withdrawal penalty
For a loan, review these terms:
- Interest rate and APR
- Fixed or adjustable rate
- Repayment term
- Monthly payment
- Origination and other fees
- Total amount paid over the loan term
A lower monthly payment may result from a longer repayment period and does not necessarily mean a lower total borrowing cost.
The Main Takeaway
“Rate” and “interest rate” usually refer to the same percentage in everyday U.S. financial language. “Interest” is the dollar amount calculated using that rate. APR helps consumers examine borrowing costs, while APY helps them compare deposit earnings that include compounding.
