- A grace period is the time between the end of a billing cycle and your payment due date. Card issuers are not required to offer one, though most cards give a grace period on purchases.
- If you pay the full balance by the due date, new purchases stay interest-free. If you do not, interest applies to the unpaid balance and to new purchases from the date each one is made.
- Grace periods generally do not cover cash advances or checks from your issuer. Interest on those usually starts on the transaction date.
- Many card companies calculate interest daily, based on your average daily balance.
What a grace period is
The CFPB defines a grace period as the period between the end of a billing cycle and the date your payment is due. Issuers are not required to offer one, but most credit cards give a grace period on purchases. The CFPB also says issuers must have procedures that ensure bills are mailed or delivered to you at least 21 days before the payment is due.
How you keep it and how you lose it
| Situation | What happens |
|---|---|
| You carry no balance and pay in full by the due date | New purchases stay interest-free. |
| You do not pay the full balance | You lose the grace period. Interest applies to the unpaid balance, and to new purchases from the date each one is made. |
| You pay in full only some months | You can lose the grace period for the month you missed and the month after. |
| You take a cash advance or use a check from your issuer | Grace periods generally do not cover these. Interest usually starts on the transaction date. |
The CFPB adds that the grace period usually applies only to new purchases, and generally only if you were not already carrying a balance. Its advice is to pay the full balance on time every month.
How interest is calculated
Many card companies calculate interest daily, based on your average daily account balance. The CFPB calls this daily charge the daily periodic rate. Because interest accrues daily, paying down all or part of your balance sooner generally reduces the interest you pay when your card has no grace period. The CFPB’s Know Before You Owe guidance adds that interest may compound daily.
A card often has more than one rate. The CFPB says card companies commonly charge one rate for purchases and different rates for cash advances, checks written on the account or other transactions. Your statement must show each category that has a different APR, along with the balance in each category.
An example with numbers
This is our own arithmetic. It assumes a 24% APR and divides it by 365 to get a daily rate. Your issuer’s agreement sets the real rate and method.
| Period | Calculation | Interest |
|---|---|---|
| One day | $1,000 x 24% / 365 | about $0.66 |
| 30 days | $1,000 x 24% x 30 / 365 | about $19.73 |
| If you paid in full and had a grace period | No interest on new purchases | $0 |
Where your payment goes
If you pay more than the minimum but less than the full balance, the CFPB says the issuer generally applies the amount above the minimum to the highest-rate balance first, then to the remaining balances in descending rate order. The issuer generally decides how to apply the minimum portion.
Other terms that change what you pay
- A penalty APR is a higher rate that a missed or late minimum payment may trigger on new purchases.
- A late or missed minimum payment may also cause a late fee and the loss of an introductory APR.
- A balance transfer fee is a percentage of the amount transferred, and an annual fee is a charge for holding the card.
- Using a card overseas can add a foreign transaction fee; see using cards abroad.
- Most significant changes to the terms require 45 days’ notice. If the issuer raises your rate, you can close the account to avoid the increase.
The CFPB pages describe how cards generally work. Your cardholder agreement and monthly statement show the exact rates, due dates and fees that apply to you. Before you apply for a card, check your free credit reports.
