Closing date and due date: how to use your card without paying interest

Every credit card has two key dates each month: the closing date (or statement date) and the due date (payment date). Understanding the difference lets you use your card as a free financing tool, instead of letting it cost you interest.

What the closing date is

It's the day the month's statement "closes": every purchase you made up to that day goes into that statement. Purchases made the next day already roll into next month's statement.

What the due date is

It's the deadline to pay the statement that just closed. There are usually 15 to 25 days between closing and due date, depending on the institution.

Why the order matters

A purchase made right after closing lands in next month's statement, and isn't due until over a month later. That same purchase made right before closing lands in this month's statement, and is due much sooner.

With this in mind, if you can choose when to make a big purchase, it's best to make it right after your closing date: it gives you the longest possible grace period to save up and pay the full balance with no interest.

The golden rule: pay the full balance, not the minimum

This strategy only works if you pay the full statement balance before the due date. If you pay the minimum, you start paying interest on the balance (see our guide on the minimum payment), and the free-grace-period advantage disappears.

How to find your dates

• Check your latest card statement: it shows the closing date and due date for that period.
• In your bank's app or website, it's usually in the card's section.
• If you can't find them, call your bank: this is information they have to give you.

Other uses of knowing your closing date

• Plan big purchases right after closing, to have more time to save up.
• Avoid surprises: if you make a purchase right before closing thinking it falls into "next month", it can land on this month's statement instead.
• Choose when to finance in installments: if you're going to finance something on your card, knowing your closing date helps you figure out which statement the first installment starts on.

What happens if you pay one day late

Missing the due date, even by a day, can add penalty interest and hurt your record if it repeats. If you know you'll be cutting it close, schedule the payment a day before the due date, not the same day.

A simple habit to adopt

Once you know your closing date, mark it on your phone's calendar as a recurring reminder a day or two before it happens. That way, if you're planning a bigger purchase, you can decide on purpose whether to make it just before or just after, instead of finding out by accident which statement it landed on.

Run the numbers on what financing costs you

If you're financing a purchase in installments on your card anyway, use the installments vs. cash calculator to see how much extra you're paying versus paying in full.

Frequently asked questions

Is the closing date the same every month?

Generally yes, though it can shift a day for weekends or holidays. Always confirm it on your latest statement.

Can I ask to change my closing date?

Some institutions allow it. Ask if you can pick a date that fits better for you, for example close to when you get paid.

Does this apply the same way to every card?

The closing/due date mechanism works the same way in general, but the number of days between the two varies by institution. Confirm yours.
