Understanding how to calculate the value of a loan based on the assignable margin is essential for anyone looking for a controlled and secure way to obtain credit. The assignable margin is an essential concept, especially for those who want to keep their finances organized and avoid surprises in their monthly budget.

In this article, we'll explore everything from the basic concept of a loan margin, through practical calculation examples, to the importance of financial planning before taking out a loan. Get ready to have all your questions answered and discover how this tool can positively impact your financial planning.

Understanding the concept of assignable margin

The assignable margin represents how much of the monthly income can be committed to paying off assigned loans. Generally, it is set at 30% of the net salary, although this percentage may vary according to current legislation.

The importance of the assignable margin is to ensure that the borrower does not commit their finances beyond what is possible, ensuring that the remaining salary is sufficient for essential expenses.

Furthermore, the margin determines the maximum amount that can be borrowed, as it limits the monthly installments. For example, with a net salary of R$3,000, the maximum installment for a payroll loan would be R$900. This protects the borrower and facilitates financial management.

Next, we will see how to calculate the assignable margin in a practical way.

How to calculate the consignable margin

Calculating your assignable margin is easy and involves a few basic steps. Here's how:

  1. Identify your net salary: Your gross salary minus taxes and mandatory deductions.
  2. Calculate the 30% margin: Multiply your net salary by 30%. This is the percentage legally permitted to be committed to installments on payroll loans.
  3. Consider additional deductions: Public servants or retirees may have additional 5% for payroll credit cards.

For example, if your net salary is R$ 4,000, the initial margin would be R$ 1,200. In other words, you can commit up to R$ 1,200 to installments on a payroll loan.

Salary directly impacts the calculation, as the higher the net salary, the greater the available margin, allowing for larger loans.

In the next section, we will discuss the legal requirements and limitations related to the assignable margin.

Legal requirements and limitations of the assignable margin

In Brazil, the consignable margin is regulated by laws that protect consumers and financial sustainability. The law sets the maximum limit at 30% of net salary, with an additional 5% for credit card loans, totaling 35%.

These rules prevent over-indebtedness by ensuring that income is available for essential expenses.

It is vital to pay attention to legislative updatesDuring economic crises, the government can adjust the margin to stimulate consumption and access to credit. During COVID-19, for example, the margin was temporarily increased in some cases.

These changes affect your ability to take out new loans. Therefore, it's important to stay up-to-date with updates to make informed financial decisions.

Next, we'll explore online tools that help you check your assignable margin.

Online tools for checking your consignable margin

Systems and applications make it easier to calculate and check your assignable margin. Here are some options:

  • My INSS: The official app for retirees and pensioners that lets you check your available margin. Log in with your CPF and password to access margin information.
  • Bank simulators: Many banks offer loan simulators that automatically calculate the margin based on your data.
  • Financial management applications: They offer features to simulate loans considering the assignable margin.

These tools are simple and practical to use, offering a clear overview of your ability to take out new loans without compromising your budget.

Next, we will see practical examples of calculating the assignable margin.

Practical examples of margin calculation

To better understand the calculation, let's look at some practical examples:

Example 1: Salary of R$ 2,500

If a worker receives a net salary of R$ 2,500, the margin would be:

  • R$ 2,500 x 0.30 = R$ 750

He can commit up to R$ 750 in payroll loans.

Example 2: Salary of R$ 6,000

For a salary of R$ 6,000:

  • R$ 6,000 x 0.30 = R$ 1,800

Therefore, you can allocate up to R$ 1,800 to the loan installments.

Variations in calculation

If there are already financial commitments, these amounts are subtracted from the available margin. For example, if R$ 300 is already committed, the available margin would be:

  • R$ 750 – R$ 300 = R$ 450

These examples demonstrate how margin varies depending on salary and existing financial commitments.

Now, let's discuss the importance of financial planning before taking out a payroll loan.

Importance of financial planning before taking out a loan

Before committing your income to a loan, it is essential to take a detailed financial planningThis ensures that the new commitment will not negatively impact your finances.

A good starting point is to create a personal budget. Here's how:

  1. List all sources of income: Include wages, pensions, rent, and other income.
  2. Map your monthly expenses: Include fixed and variable expenses.
  3. Calculate your available margin: Determine the assignable margin and deduct existing commitments.
  4. Consider an emergency fund: Set aside a portion of your income for emergencies.
  5. Adjust the budget: If the new installment compromises basic expenses, reevaluate or adjust other expenses.

Planning is vital to prevent financial problems, allowing you to keep your bills up to date and your quality of life stable.

Below, we'll compare different types of loans and their margins to help you make an informed choice.

Comparison between different types of loans and their margins

There are different types of loans on the market, each with its own features, advantages and disadvantagesLet's compare them with payroll loans in terms of margin and conditions.

Advantages of a payroll loan

  • Lower interest rates: Banks offer more favorable terms due to the security of direct debit from payroll.
  • Ease of approval: With the guarantee of salary or benefits, credit analysis is faster and less rigorous.

Disadvantages of payroll loans

  • Margin commitment: Limits the ability to take on other credits.
  • Risk of over-indebtedness: Even with lower rates, it's easy to lose control when you add up multiple obligations.

Other types of loans

  • Personal loan: Not limited by the assignable margin and offers greater flexibility, but with generally higher interest rates.
  • Credit card: It offers revolving credit, but with often very high interest rates.
  • Special check: Easy access in emergencies, but charges some of the highest rates on the market.

Payroll loans are attractive due to their rates, but it's important to evaluate all options to ensure the best financial decision for your needs.

Next, we'll look at how the new margin can impact your personal budget.

Impact of the new margin on personal budget

THE use of a new assignable margin can bring changes to the monthly budget, requiring adjustments to maintain financial balance. Adding a new loan installment reduces available income for other expenses.

This impact can be felt in different ways:

  • Reduced purchasing power: With part of your income compromised, variable expenses, such as leisure and food, may need to be reduced.
  • Less financial flexibility: Significant fixed commitments can limit the ability to respond to unforeseen events.

To adapt your budget to this new reality, consider the following strategies:

  1. Review expense categories: Identify and cut unnecessary expenses, prioritizing what is essential.
  2. Set savings goals: Set savings goals, even modest ones, to ensure some financial reserves.
  3. Monitor your spending regularly: Use apps or spreadsheets to track expenses and ensure you're staying within your budget.
  4. Renegotiate debts if necessary: If the installment of the loan puts too much strain on your budget, consider renegotiating the loan terms.

In the next section, we will answer frequently asked questions about the assignable margin to clarify common doubts.
