A purchase interest rate is the credit-card rate that applies to ordinary purchases when the balance is carried.
Purchase interest rate means the credit-card rate that applies to ordinary purchases when the balance is carried under the card’s rules. In practical terms, it is the borrowing cost tied to regular card spending once the account is no longer benefiting from full grace-period treatment on those purchases.
Purchase interest rate matters because it often determines whether a carried card balance becomes manageable or expensive. A borrower who understands the purchase rate can better judge the real cost of repaying over time instead of focusing only on the minimum payment.
It also matters because many readers assume one card has one single price for every kind of balance. In reality, purchase transactions, Cash Advance transactions, and Balance Transfer balances may all have different pricing treatment.
In Canada, the purchase interest rate appears in the cardholder agreement and cost-of-borrowing disclosure for the account. It usually applies when a borrower carries purchase balances instead of paying the full Statement Balance by the due date under the card’s Grace Period rules.
The rate should be read together with the statement date, due date, and balance type. A borrower who pays in full may avoid purchase interest for that cycle, while a borrower who revolves a balance may start paying this rate on the purchase portion of what is owed. Issuer terms can vary, so the exact mechanics still depend on the agreement.
A borrower charges $1,000 of ordinary purchases to a card and pays only part of the statement balance by the due date. The remaining purchase balance may then be subject to the purchase interest rate, which turns everyday spending into interest-bearing debt.
Purchase interest rate is not the same as an Annual Fee. The fee is a card cost for holding the account, while the purchase rate is the borrowing cost for carried purchase balances.
It is also different from a Cash Advance Fee or the pricing for cash advances. Those costs apply to cash-like transactions rather than ordinary purchases.
