Have you ever tried to make an installment purchase, apply for a credit card, or finance an asset and heard about “Serasa Score”? For many Brazilians, this number is the difference between having credit approved or receiving a “no” at the least expected moment. But few truly understand what it means, how it is calculated, and — most importantly — what is within their reach to improve it.
The Serasa Score is a credit score, on a scale from 0 to 1,000, indicating the likelihood of a person paying their debts on time over the next 12 months. The higher the number, the lower the risk perceived by the market — and the greater the chances of credit approval with more favorable conditions. It is produced by Serasa Experian, one of the main credit bureaus in Brazil, and is widely used by banks, financial institutions, stores, and telecom operators when evaluating a credit application.
Understanding this score and its logic is an essential step for anyone who wants to make more conscious financial decisions. In this article, you will learn what the Serasa Score really represents, which factors go into its calculation, what myths surround the topic, and how to monitor and gradually improve your score.
What is the Serasa Score and What is it Used For?
The Serasa Score is an individual credit rating calculated by statistical algorithms that analyze a person’s financial history. The score ranges from 0 to 1,000 and is divided into bands that indicate the level of default risk:
Score Range
Classification
Market Perceived Risk
0 to 300
Low
High risk of default
301 to 500
Regular
Elevated risk
501 to 700
Good
Moderate risk
701 to 1,000
Very Good / Excellent
Low risk of default
These bands are defined by Serasa Experian itself and can be checked directly on the company’s official website or app. It is worth remembering that each financial institution has its own approval criteria — the score is an important input, but not the only factor analyzed.
The Score serves, in practice, for companies to make quicker decisions about granting credit. For consumers, it functions as a “thermometer” of their current financial history.
How the Serasa Score is Calculated
The calculation of the Serasa Score is based on a proprietary statistical model, which means that the exact formula is not publicly disclosed. However, Serasa Experian informs the main groups of variables that influence the score. Understanding them is crucial to knowing where to act:
1. Commitment to Credit (Payment History)
This is generally the most weighted factor. It analyzes whether you usually pay your bills on time — loans, credit cards, bills, etc. Delays and defaults significantly reduce the score. Timely payments, over time, contribute positively.
2. Record of Debts and Liabilities
The existence of negative debts on the CPF (such as a name listed in credit bureaus) has a significant and negative impact on the score. After settling or agreeing on a debt, the negative record should be removed within 5 business days, as provided by the Positive Registration Law and Central Bank regulations.
3. Inquiries to the CPF
When a company checks your CPF to evaluate a credit application, it generates a record. Many inquiries in a short period may indicate that you are seeking credit intensely, which can be interpreted as a sign of financial difficulty and slightly reduce the score.
4. Positive Registration
The Positive Registration, regulated by Law No. 12,414/2011 and managed by credit bureaus, records payment history — not only overdue debts but also payments made on time. Automatic inclusion in the Positive Registration (in effect since 2019) brought more information for score calculation, benefiting consumers with a good payment history. You can request to leave the Positive Registration, but this may affect your score.
5. Length of Relationship with the Credit Market
Having a longer history of responsible credit use tends to be positive. Consumers without a history — such as young people starting to use credit — may have lower scores simply due to lack of data, not poor financial behavior.
What Does NOT Influence the Serasa Score
There are several myths about what affects the score. It is important to clarify what, according to Serasa itself, is not used in the calculation:
Current salary or income
Bank account balance or investments
Profession or education level
Gender, race, religion, or marital status
Address or neighborhood where you live
These data simply do not enter the score model. The confusion arises because some financial institutions use this information in their own internal credit models — but this is different from the Serasa Score itself.
How to Check Your Serasa Score for Free
Since 2019, Serasa has made the score consultation free. Here’s how to do it:
Access the official site serasa.com.br or download the “Serasa” app (available for Android and iOS).
Create a free account with your CPF, date of birth, and a valid email address.
Confirm your identity through security questions or SMS validation.
After registration, your Score appears on the app or site home screen.
Besides the score, you can see which factors are positively or negatively impacting your score.
The consultation is free and does not affect your score — only inquiries made by companies for credit analysis generate a record.
How to Improve Your Serasa Score in Practice
Improving the Score is a process that takes time and requires consistency. There is no legitimate shortcut — be wary of services that promise to “increase the score quickly” for a fee, as many are scams. What truly works:
Settle open debts: If you have negative debts, the first step is to negotiate and settle them. Serasa offers a negotiation platform called “Limpa Nome” with installment proposals.
Pay your bills on time: Paying water, electricity, phone, credit card, and bills on time builds a positive history over the months.
Keep your registration data updated: Updated address, phone, and email at Serasa help improve your score in the “registration update” component.
Use credit in moderation: Do not apply for several cards or loans at the same time. Many inquiries in a short time can signal financial mismanagement.
Stay in the Positive Registration: With a good payment history, the Positive Registration works in favor of your score.
