Low Credit Score? Here’s How to Improve Yours
You tried to apply for a credit card, a loan, or even a post-paid phone plan and received a rejection without understanding why? There’s a good chance that your credit score — that score that summarizes your financial history — is low. This score is consulted by banks, financial institutions, stores, and even service companies to assess the risk of granting credit to a person. The lower it is, the greater the perceived risk and the harder — and more expensive — it becomes to access credit.
The good news is that your score is not a permanent sentence. It’s dynamic, calculated based on financial behaviors that can change over time. With discipline and the right strategies, it’s possible to improve your score consistently — without magical shortcuts or miracle promises. This article explains how this system works, what lowers your score, and most importantly, what you can do practically to rebuild it.

What is a Credit Score and How Is It Calculated
A credit score is a rating that generally ranges from 0 to 1000. It’s calculated by credit bureaus — companies like Serasa, SPC Brasil, and Boa Vista — based on your financial history data. The higher the score, the lower the risk perceived by the market.
Each bureau has its own methodology, but the main factors considered typically include:
- Payment history: whether you pay your bills on time or accumulate delays
- Outstanding debts or negative registrations: your name listed in defaulter databases
- Length of relationship with the credit market: the longer and healthier, the better
- CPF inquiries: many inquiries in a short time may indicate desperation for credit
- Updated registration data: correct name, address, and information with the bureaus
With the regulation of the Positive Registration by the Central Bank — a mechanism that also records on-time payment history, not just defaults — credit scores now reflect positive financial behavior more fairly. This represents a real opportunity for those with good habits but still carrying a score hurt by the past.
Why Your Score Drops: The Main Culprits
Before thinking about improving, it’s essential to understand what lowers your score. The most common factors are:
- Default and negative registration: having your name listed with Serasa or SPC is the factor with the greatest negative impact
- Frequent delays: even without formal default, recurring delays harm your history
- Unpaid debts: the older and more numerous, the worse the effect
- Outdated registration: wrong or outdated data with the bureaus reduces your profile’s credibility
- Lack of history: paradoxically, having no financial activity can also result in a low score, as there’s no positive data to analyze
Step-by-Step Guide to Improve Your Score
Improving your score is a medium-term process. There are no legitimate immediate solutions — be suspicious of any service promising to increase your score quickly in exchange for payment. Here’s what actually works:
- Check your score and CPF for free. Access the official websites of the bureaus (Serasa, Boa Vista, or SPC Brasil) to check your current score and identify any outstanding issues or defaults. Basic consultation is free.
- Pay off or negotiate outstanding debts. Defaulted debts are the biggest obstacle. Prioritize them. Platforms like Serasa Limpa Nome and the Central Bank’s Negotiation Outreach with partner entities typically offer special negotiation terms during specific periods — it’s worth following the official calendar.
- Update your registration data. Keep your name, address, email, and phone number updated in the bureaus’ records. Correct information increases your profile’s credibility.
- Pay all bills on time, always. Once you start paying everything on time — electricity, water, phone, credit card, invoices — positive history begins to accumulate. The effect isn’t immediate, but it’s consistent.
- Activate Positive Registration. Check if you’re already included in Positive Registration (nowadays inclusion is automatic, but it’s worth confirming). This mechanism records your on-time payments and can directly benefit your score.
- Avoid requesting multiple credits at the same time. Each inquiry about your CPF is recorded. Many inquiries in a short period may indicate financial instability and hurt your score. Research options before formally applying.
- Maintain an active and healthy financial relationship. Having a regularly active bank account, responsibly using a credit card, and paying it off in full by the due date contributes to building a positive history over time.
The Role of Positive Registration in Your Score
The Positive Registration was regulated by the Central Bank and is managed by credit bureaus under the regulator’s supervision. Instead of recording only those who didn’t pay, it records those who did — and on time. This changes the system’s logic: people who always honored their commitments but had little formal credit history now have positive data computed.
If you have good payment habits, Positive Registration works in your favor. To verify if you’re included and how your data is being used, visit your preferred bureau’s website or check the information available from the Central Bank on its official portal (bcb.gov.br).
Beware of Scams and False Promises
This is a critical point: the market for “name cleaning” and “score boosting” is full of scams. There is no legal way to increase a score quickly by paying third parties. No company can erase legitimate defaults before the legal five-year deadline, nor can they “hack” the bureaus’ systems.
Be suspicious of any service that:
- Promises to increase your score in days or weeks
- Charges upfront fees to “solve” your situation
- Guarantees removal of defaults without paying off the debt
- Asks for your banking details or account access
Debt negotiation can be done directly with creditors or through the official platforms of the bureaus — without paid intermediaries. If you need legal help, contact the Public Defender’s Office or a trusted lawyer.
How Long Does It Take for Your Score to Improve?
There’s no exact answer, because the score depends on multiple factors and each bureau has its own methodology. What experience and guidance from the bureaus themselves indicate is:
- Defaults are removed from the record after five years from the debt’s due date — but paying off the debt accelerates score improvement even before then, as the default is removed after payment
- Positive history begins to be noticed in just a few months of consistent behavior
- Significant recovery tends to occur within six months to two years, depending on the depth of previous problems
The key is understanding that your score is a reflection of your financial behavior over time. There is no finish line: it’s continuous management.
A High Score Isn’t the Final Goal — It’s a Consequence
It’s important to be clear about this: improving your score shouldn’t be an end in itself, but a consequence of a more organized and healthy financial life. A high score opens doors — better credit conditions, lower interest rates, easier financing for property or vehicles — but the real goal is financial health.
For this, organizing your budget, controlling expenses, building an emergency fund, and with time, starting to invest are steps that go hand in hand with score improvement. Check our complete guide on Annual Financial Planning: How to Organize 2026 to take that next step in a structured way.
Conclusion
Having a low credit score is uncomfortable, but reversible. The path involves understanding the factors that compose it, negotiating and paying off pending debts, consistently keeping payments on time, and building a positive financial history over time. There are no legitimate shortcuts — but there are clear and accessible steps that anyone can start taking today.
Start by checking your score and CPF for free on the official websites of the bureaus. Identify what’s weighing negatively. Prioritize regularization. And above all, adopt financial habits that sustain this improvement in the long term. Time is your ally when you’re on the right path.
