Read the interest charges on your credit card statement and see where each comes from
Interest charges are what a card issuer adds when a balance is carried past the grace period, or immediately on balances such as cash advances that usually have none. The statement splits them by balance type and lists the APR, the balance subject to interest and any promotional rate. Ask Search+ "How much interest was charged this cycle, and on which balance?" and the cited excerpt shows you the issuer's own interest section.

How to read interest charges with Search+
- Upload consecutive statements and the agreement
Interest in one month often depends on what happened the month before, such as a balance not paid in full. Add at least two consecutive statements, as PDF or Excel files saved from your card account, and the cardholder agreement, which explains how the issuer calculates interest.
- Ask about each balance type on its own
Ask separately about interest on purchases, on balance transfers and on cash advances, and about any promotional or penalty rate. Each balance type has its own line in the interest calculation table and often its own rate.
- Follow the interest back to its cause
Open the cited interest section, then ask what the previous statement's balance and payment were. If a promotional rate is involved, ask the statement for its end date and what rate follows.

Does this store card statement mention deferred interest on a promotional purchase, and the date by which it must be paid?
What to look for in interest charges
On many cards, paying the full statement balance by the due date means no interest on new purchases. Once a balance is carried, that grace period can be lost until the balance is paid in full again, and interest can show up for a cycle or two after you pay.
Cash advances and some cash-like transactions often start accruing interest from the day they post, frequently at a higher APR and with a separate fee. The interest calculation table shows them on their own line.
A promotional APR applies for a set period; a penalty APR may apply after a late or returned payment, under the issuer's terms; deferred interest offers, common on store cards, can charge interest back to the purchase date if the balance is not paid within the promotional period.
In the US, statements show interest by balance type with the APR and the balance subject to interest rate. The method behind that balance, often a daily balance, is described in the cardholder agreement.
Search+ answers cite the interest section and transaction lines they used. AI answers can be incomplete or wrong, so open the citation before relying on an interest figure.

What are interest charges on a credit card statement?
Interest charges are the finance charges an issuer adds to a balance for borrowing, calculated by applying the APR for each balance type to the balance subject to interest during the billing cycle.
