Interest rates

The facts about Interest Rates

What affects the economy can also affect interest rates on your business credit card. Changes in your personal and business financial situation, including income, amount of debt and other factors can also affect interest rates.

Some cards have a fixed Annual Percentage Rate (APR) and many credit card issuers are currently offering a variable APR that is tied to an index.

  • If your APR is fixed: it will not vary with changes in an Index and most credit card issuers will use the Daily Periodic Rate (DPR) to calculate the finance charges you will see on your monthly credit card statement.
  • If your APR is variable: your interest rate will vary with changes to the Index it is tied to (most commonly the U.S. Prime Rate.) Most credit card issuers calculate the variable rate using a formula that adds a margin they determine to the Index rate.
Fixedinterest rate example Variableinterest rate example
If your APR is 16.75%, divide it by 365 days in the year. 16.75% ÷ 365 = 0.00046 Your current margin is 13.5% and the current Index is 3.25% which makes your current APR. 13.5% + 3.25% = 16.75%
Multiply that by your average daily balance of $500. 0.00046 × $500 = $0.2295. Divide your APR of 16.75% by 365 days in the year. 16.75% ÷ 365 = 0.00046
Multiply that by a 30-day billing cycle (e.g., 30). $0.2295 × 30 =$6.88 Multiply that by your average daily balance of $500. 0.00046 × $500 = $0.2295
Multiply that by the number of days in the billing cycle (e.g., 30). $0.2295 × 30 =$6.88

This chart is for illustrative purposes only. Your APR and finance charges, and how they are calculated, may vary.

Reasons for interest rate changes

The finance charge you pay is largely determined by your interest rate, also referred to as your Annual Percentage Rate (APR). The APR on your account can adjust up or down over time from its initial point, for a number of reasons explained below.

Remember, you can pay more than the minimum amount due at any time. Paying your balance in full or making larger payments when possible can significantly reduce your cost of credit.

Economic & industry factors

Everything that affects the larger economy can also affect your business credit card interest rate. For instance, if the interest rate banks pay to borrow money changes, it may have an impact on your APR. On a variable rate account, the APRs will fluctuate with the index to which they are tied—most commonly, the Prime Rate.

Personal or business financial changes

Changes in your personal and/or business financial situation, including changes in your income, your amount of debt, your overall credit history and how you use and maintain your business credit card with us can all affect your interest rate. You should strive to maintain a good credit rating at all times.

Promotional rates are special business credit card APRs that have a set expiration date.

  • When they expire, your APR increases to the non-promotional rate

When taking advantage of a promotional offer, make sure you keep track of when the offer expires so you'll know when your APR increases to the non-promotional rate.

The cut-off time is usually before the banking center closes and varies by banking center. The cut-off time for an ATM is usually posted on the ATM. Cut-off Times for business credit and charge card payments are stated on your agreement and on your statement.

Interest Rates

Different types of accounts and loans pay or charge different rates of interest and are expressed as a rate per period of time. For example, the Interest Rate paid for funds held in an interest-bearing account, such as savings, CDs and some checking accounts. An Interest Rate can also refer to the rate charged on an outstanding balance on a loan or line of credit.
Savings Accounts
A banking account in which you place funds and receive interest for doing so. Savings accounts are FDIC insured to the maximum amount allowed by law. There are many savings options to choose from so that you can save the way you prefer.
Account Balances
For checking and savings accounts, your account balance is based on the funds put into your account (credits) and the funds taken out of your account (debits). We process debits and credits each business day. For credit and charge cards, it's the total amount owed on the account at a designated time, as reflected on your monthly statement.
Posted Transactions
When a transaction or item appears on your account statement, it is referred to as having "posted." Posted transactions have been processed by the Bank, but funds for the transaction may still be in transit. Unposted transactions have not yet been processed, but may affect the amount of credit available. See your Account Agreement for details.
Available Balance
Your Available Balance is the amount of funds in your checking or savings account that is currently available for you. It includes all Cleared and Processing transactions. Keep in mind that any transactions you have made but Bank of America has not yet received need to be subtracted from your Available Balance for you to know the exact amount of funds you have to spend or withdraw. The Available Balance does not include:
  • Any transaction that has not been received by the bank (check, recurring Debit Card transactions, ACH)
  • Amount of a deposit not currently available, including holds
  • Debit Card transactions identified as Authorized
Direct Deposits
Direct Deposit is a service that automatically transfers your recurring deposits to your checking or savings account. Recurring deposits can include: salary, pension, Social Security and Supplemental Income (SSI) benefits, or other regular monthly income.
Account Statements

Finance Charges
The finance charge is the interest plus certain transaction fees charged on your credit card account.
Minimum Daily Balance
This term relates to checking and savings accounts. To determine the Minimum Daily Balance, we look at the lowest daily balance you had in your checking or savings account during a statement cycle. For many of our accounts, we use the Minimum Daily Balance to determine whether a monthly maintenance fee will be charged to your account.
An account is overdrawn when it has been drawn on in excess of available funds.
A hold is a delay in the availability of funds you have deposited into your checking or savings account. When Bank of America places a hold on your deposit, you will not be able to use the funds until the hold expires. Holds occur infrequently and if you receive one, you will receive a notice with the reason and the date the funds will be available. A check may be held for several reasons: The check is for an amount larger than you normally deposit; the source of the check; we suspect that we cannot collect the funds from the account the check is drawn on; or there have been previous overdrafts from this account.
Checking Account
A banking account in which you place funds and withdraw available funds on demand, typically by using a debit card or writing a check. Checking accounts are FDIC insured to the maximum amount allowed by law. There are checking account options to choose from so that you can bank the way you prefer.
Annual Percentage Rate
The yearly rate of interest. The APR is listed in the account agreement as well as on monthly billing statements.
U.S. Prime Rate
The U.S. Prime Rate is the prime lending rate offered by a number of the country's largest banks. It is frequently cited as a standard for general interest-rate levels in the economy. The U.S. Prime Rate is often used to calculate variable interest rates. A set number, or margin, determined by the issuer, is added to the U.S. Prime Rate to get the variable interest rate. When the Prime Rate goes up or down, the variable rate may change.
Average Daily Balance
For checking and savings accounts, it is the sum of the daily account balances during a period, usually a monthly statement cycle, divided by the number of days in the period. For credit card accounts, it is the balance subject to finance charge that calculates the balance for each day during the statement cycle. The average daily balance is determined by adding up the daily balances, then dividing them by the number of days in the cycle.
Promotional Rates
A rate that is lower than your standard interest rate and is valid only for certain transactions for a limited period of time.
Grace Period
A grace period is basically an interest-free period between the time of a purchase and the payment due date shown on your next statement. Cash advances generally do not have a grace period. There is no grace period for payments; payments are due no later than the payment due date. See your Agreement for how the grace period on your credit card account applies.
Cash Advance
Transaction to access cash from a credit and charge card account. Cash advances can be made using an ATM, at a bank, by phone or through a credit and charge card cash advance check. Cash advances are not available on all products.
Unsecured Line of Credit
A line of credit is an account under which you may access funds up to an agreed upon maximum. Interest is only charged on the funds that are actually withdrawn from the line of credit. With an unsecured line of credit, the bank does not hold any of the borrower's property as collateral.
