How to Analyze Your Credit Card Statement

Five blocks every statement has (and no one taught you to separate).

Credit card statements are the financial document that causes the most anxiety in Brazil. Not because they are inherently difficult, but because they are presented in a scrambled chronological order, without separating new spending from inherited commitments. This guide separates them.

Block 1: Current Month Purchases

These are the purchases you made in this cycle, without installments. Here lies your current consumption behavior. If this block is high, it is your decision now. It is not a problem from last month.

Block 2: Open Installments

Purchases from previous months that still have ongoing installments. Here lies the "inherited liability". You cannot change this number this month, it is already contracted. But you can look at it differently.

Block 3: Charges and Fees

Here lies the silent drain. Annual fee, IOF (Tax on Financial Operations), revolving interest (if you did not pay in full the previous month), late payment penalty. Mark them all.

Charge	What It Is
Annual Fee	Annual card fee (charged monthly on some cards, annually on others).
National IOF	0.38% on each purchase, automatic.
International IOF	3.38% on foreign currency purchases (in 2026).
Revolving Interest	350-450% per year if you paid only the minimum in the previous cycle.
Late Payment Penalty	2% on the unpaid amount + late interest.

Block 4: Payments and Refunds

Check if the previous statement payment was credited, if refund returns appeared, and if cashbacks were posted. In 5% of cases, there is a discrepancy. It is worth checking.

Block 5: Committed Credit

The card shows "total limit" and "available limit". The difference is your committed credit, including installments that have not yet appeared on the statement.

This is the number that best measures your credit usage health. If you are using more than 50% of the limit month to month, there is an operational dependency on the card. It may be intentional (cash flow management) or a symptom (tight budget).

Common Mistakes When Reading a Statement

Only looking at the total open amount, without separating new spending from inherited commitment.
Paying the minimum thinking it is "under control". The minimum generates revolving interest, it is the worst deal on the market.
Not checking IOF on international purchases (still 3.38% in 2026).
Confusing available limit with money you have.

Perguntas frequentes

Why is my statement high if I did not buy much this month?

It is almost always installments from previous months falling now. Separate the "current cycle purchases" block from the "open installments" block to understand if the problem is from the past or the present.

Is it better to pay the minimum statement or use personal credit?

Almost always personal credit. Credit card revolving interest is between 350% and 450% per year in 2026. Bank personal credit varies between 60% and 200%. The difference pays for a complete renegotiation in 1-3 months.

What is committed credit?

It is your total limit minus the available limit. It includes purchases made, future installments, and open statements. Keeping it below 50% is usually a sign of healthy credit card usage.

Is there a quick way to see all this without reading the entire statement?

Yes. Monse processes the statement PDF and automatically separates the 5 blocks, with charges highlighted. In 2 minutes you see what would take 25 minutes manually.
