what is a purchase rate on a credit card
The purchase rate on a credit card is the interest rate you’re charged on everyday purchases if you don’t pay your statement balance in full by the due date.
What “purchase rate” means
- It’s the card’s interest rate for normal spend (groceries, gas, online shopping, etc.).
- You’ll see it shown as an APR (annual percentage rate), often around 18%–22% on many standard cards.
- It only kicks in when you carry a balance past the due date; if you pay in full and on time, you usually pay no interest on purchases.
How the purchase rate works
- You make purchases on your card during the month.
- Your statement is issued with a due date and a total amount owing.
- If you pay the full statement balance by the due date, no purchase interest is charged (thanks to a grace period).
- If you pay less than the full balance, interest is charged on the unpaid portion at the purchase rate, calculated daily and added monthly.
Quick example
- Balance from purchases: 2,000.
- You pay: 200 by the due date.
- Remaining 1,800 accrues interest at the card’s purchase rate until it’s paid off.
Purchase rate vs other APRs
Credit cards can have multiple APRs:
- Purchase rate / purchase APR: for regular purchases.
- Cash advance rate: usually higher, applied to ATM withdrawals and similar transactions, often with no grace period.
- Balance transfer rate: often a special (sometimes lower) rate on transferred balances for a promo period.
| Type | What it applies to | Typical rate level |
|---|---|---|
| Purchase rate | Everyday card purchases | Standard advertised APR (e.g., ~18–22%) | [10][5][3][1]
| Cash advance rate | ATM withdrawals, cash-like transactions | Often higher than purchase rate | [4][5]
| Balance transfer rate | Debt moved from another card | Can be low or promotional for a set period | [4][5][1]
Why the purchase rate matters
- It’s the core “cost of borrowing” if you don’t clear your balance monthly.
- A lower purchase rate can reduce how fast interest builds if you carry a balance.
- Good credit scores can help you qualify for lower purchase APRs.
Simple rule of thumb
If you regularly pay your credit card in full and on time, the purchase rate often doesn’t cost you anything.
