If you use a credit card, you've probably heard that there's a "best day" for credit card purchases. But do you know what this means and what benefits it can bring to you as a customer?

To answer your questions, we've gathered all the information you need about the best day to purchase with your credit card, how it works, and how you can take advantage of this day to extend your payment terms.

Follow the article and find out everything you need to know about buying on the best shopping day.

What is the best day to buy on a credit card?

The concept of “best day to buy” refers to choosing the most favorable date to make purchases using a credit card, in order to obtain the longest period before the start of payment.

When your bill is set to be due on the same date every month, you may experience a difference of up to 40 or 45 days between the date of purchase and the date of your first payment.

This advantage is possible because the invoice is closed a few days before the due date. Therefore, by making a purchase immediately after the invoice closes, the consumer can enjoy an extended period before the initial payment is due.

How does the best day to buy card work?

The "best day to buy" credit card strategy refers to the strategy of choosing the most appropriate date to make a purchase, taking into account the maximum time available before payment is due. How this works varies depending on the policies and practices of the card-issuing financial institution, but generally follows these steps:

  • Invoice closing: The financial institution sets a specific invoice closing date, which is the day the billing period ends and records all transactions made during that period. After closing, no new transactions are added to the current invoice.
  • Due date: The invoice has a due date, which is the deadline for making the full payment or the minimum required amount. This date is usually a few weeks after the invoice closes.
  • Best day to buy: To make the most of the interest-free period, consumers try to make purchases immediately after their bill closes. This allows for a longer period of time between the purchase date and the payment due date.

For example, if the bill is due on the 10th of each month and the due date is the 15th, a consumer who makes a purchase on the 11th will have more than a full month before needing to pay for the purchase.

 

What is the best day to purchase with a card?

The best day to make a purchase with your card is the day after your bill closes, as this gives you more time to pay your bill and gives you a few extra days to make the payment.

Major institutions in Brazil usually close invoices 5, 7, 10 or 15 days before the invoice is due.

So, if your bill is due on the 8th, the 9th is the best day to purchase the card, as you will have a longer payment period.

See the table below for the best day to purchase with your card, considering 10 days until expiration, which is the table used by Itaú, Banco do Brasil, and other institutions. Therefore, when you purchase on the best day, you have 40 days to make your payment:

Invoice due date Invoice closing Best shopping day
01 21 22
02 22 23
03 23 24
04 24 25
05 25 26

26 16 17
27 17 18
28 18 19
29 19 20
30 20 21

 

Institutions like Nubank, Picpay, and others use a slightly different timetable. The timetable that separates the invoice closing date from the payment date is 7 days. Therefore, when purchasing on the card's best purchase date, you can have up to 37 days to pay:

Invoice due date Invoice closing Best shopping day
01 24 25
02 25 26
03 26 27
04 27 28
05 28 29
06 29 30
07 30 01
08 01 02
09 02 03
10 03 04
11 04 05
12 05 06
13 06 07
14 07 08
15 08 09
16 09 10

26 19 20
27 20 21
28 21 22
29 22 23
30 23 24

 

Knowing the invoice closing date, the next day is the best day to purchase to give you more time.
