A very common question among consumers concerns the total limit of the credit card. After all, how is the calculation of the purchasing power of the card? In Brazil, the operators basically follow two models:

- adding the total amount spent by the cardholder in all of his transactions, regardless of the number of parcels chosen in his purchases;
- the limit that takes into account only the invoice total for the current month.

Here are examples of how the account is done in practice.

## Total value of invoices

This is the most common model used by credit card providers. In it, the consumer must pay attention to everything he has spent on his transactions. And that has not yet been paid on the last invoice.

Let us assume that the total limit granted by the administrator is R $ 1,000. The first purchase made has a total value of $ 700 and is split in 10 times. In that case, there is still $ 300 left for the cardholder to use.

The consumer continues to make purchases with his card and, until the end of that month, he spends more R $ 250. Thus, the invoice for that period closes at R $ 350 – the R $ 100 of the portion of the first purchase added to the R $ 250 of the other transactions.

Until the invoice is cleared and the administrator detects your payment, the customer still has $ 50 free to use. After that, the limit of the card available becomes R $ 400, since there is still a debt of R $ 600 to be paid in the coming months – precisely the six installments of R $ 100 of that first transaction.

## Each time you drop one of the installments

The total balance for use is increased by $ 100. At the end of the seven months, if a new installment purchase is not made, the available limit returns to its original value of $ 1,000 .

It is worth remembering that the credit card owner must take into account to the account of that limit possible fixed expenses that enter into the invoice every month. Case of streaming service signatures, for example. If the customer has contracted a service of $ 50, every month, on the day determined in the contract with the company, this amount will appear on the invoice. Therefore, it is important that the cardholder always leave a kind of reserve of $ 50 so that, at the time the amount appears on the invoice, the limit is not exceeded. By exceeding the limit, the consumer may be required to pay interest and other financial charges.

## Total invoice amount for the current month

For this modality, we will use the same example from the previous case. A credit card with a total limit of R $ 1,000 with a purchase of R $ 700 divided in 10 times. As each installment will be R $ 100, the limit automatically becomes R $ 900. This is the amount that the customer will have to spend in the 7 months in which the purchase appears on your invoice.

Assuming a new installment purchase is made, this time of 3 times of R $ 150. In this case, the limit for the next 3 months becomes R $ 750.

In the video below we explain how the credit card limit works with examples.

It is important to be aware of what modality the operator offers when hiring the credit card service. In addition, it is never too much to point out that in any case it is essential to have control of the total expenses made in the month. Many carriers offer the customer the possibility to be advised by the cell phone of each completed transaction. Or the receipt of alert messages near the end of the limit for that month.
