Bank loans can cost twice the amount. Understand the CET, compound interest, and see why anticipating your contract is the smartest choice.

João Filipe Carneiro
Every creator, agency, or producer reaches a turning point. It is that moment when the vision for the future becomes greater than the present resources. It is the need for that new camera that will elevate the quality of your production, the best-equipped studio for your podcast, the hiring of an editor to scale your content, or simply the working capital to give breath to the business while the big payments do not arrive. The dream is clear, but it requires capital.
For most, the first path that comes to mind is the most traditional: a personal loan from the bank. The promise sounds tempting, with monthly interest rates prominently advertised. But that's where reality starts to dangerously drift away from the advertising.
Let’s engage in a "serious game", as proposed in our foundational material. Using real data from a survey by Procon-SP with the six largest banks in the country in May 2025, imagine that you only borrow R$ 100 to pay back in 12 months. What happens at the end?
At Bank A, you pay R$ 212.10.
At Bank B, you pay R$ 255.10.
And in the most extreme case, you pay R$ 279.60.
You read that right. At best, you pay more than double what you borrowed. This is not an anomaly; it’s the norm. The advertised interest rate is just the beginning of the story, the tip of an iceberg of costs that remains submerged in the fine print of the contract.
This article is your flashlight. Our goal is to dive deep and illuminate this black box of traditional credit. We will dissect what really comprises the cost of a loan, why it becomes so expensive, and, more importantly, present the alternative model that has become the smart choice for the creative economy. It’s time to decode the system so you can make the right decision, not for the bank, but for your growth.
The Anatomy of Banking Costs: Unveiling the CET Acronym
To understand why those R$ 100 from our example transformed into nearly R$ 280, we need to act like a mechanic: disassemble the engine of a bank loan and analyze its parts. The main one, the one you absolutely need to know, is a three-letter acronym: CET.
CET stands for Total Effective Cost.
By law, established by the Central Bank, every financial institution is required to inform the CET before you sign any credit contract. Think of it as the final and complete price of your flight after all fees, taxes, and baggage charges. The advertised interest rate is just the fare, but the CET is the amount that will actually come out of your pocket.
Let’s break it down. The CET is the sum of several components:
The Nominal Interest Rate: This is the "star of the show", the rate that the bank advertises in bold letters. It is the rent that the bank charges for the money it is lending you. Alone, it seems manageable, but it’s just the first item on the bill.
Taxes (Mainly IOF): This is where the bill starts to grow. Every credit operation in Brazil has the incidence of IOF (Tax on Financial Operations). It is a federal tax, not a bank fee. In a personal loan, it has a fixed rate of 0.38% on the total amount you borrowed, plus a daily fee that increases the cost, especially in the first months. It’s an immediate and unavoidable cost, added directly to your outstanding balance.
Fees and Insurance: This is the murkiest area. Various charges may apply, such as administrative or registration fees. The most common, however, is Credit Insurance. This insurance serves to pay off the debt in the event of death or disability. While it can be useful in some situations, it is crucial to know: the purchase of this insurance is optional. Often, it is "pushed" into the package, inflating the total cost of your loan. Refusing it is your right.
When you add the nominal interest rate + the IOF + the fees + the insurance, you arrive at the Total Effective Cost (CET). That’s why an advertised rate of 6% per month can turn into a much higher real cost. The bank that appears cheaper in the advertisement may be the most expensive in practice. The only way to compare credit proposals fairly is by looking at a single metric: the CET.
Great. Now that we know the parts, let’s see how the debt engine accelerates on its own.
The Mathematics of Debt: Compound Interest in Action
If the CET is the set of parts that makes the loan expensive, compound interest is the engine that makes this debt grow exponentially. Albert Einstein supposedly called it "the eighth wonder of the world", claiming that "he who understands it, earns; he who does not understand it, pays." In a bank loan, unfortunately, you are on the side that pays.
The concept is "interest on interest". Unlike simple interest, which always applies to the initial amount, compound interest applies to the total amount each month — that is, to the initial amount plus the accrued interest from previous months.
It's a snowball rolling downhill. And it grows much faster than one imagines.
Let’s revisit our example of R$ 100 borrowed and use one of the rates from the survey, 8.57% per month, to illustrate the destructive power of compound interest. (Note: this is a simplified simulation to show the concept; a real loan involves installments, but the principle of debt capitalization is the same).
Month 1: You start owing R$ 100. With 8.57% interest, your debt rises to R$ 108.57.
Month 2: Now comes the catch. The next 8.57% do not apply to the original R$ 100 anymore, but to R$ 108.57. Your debt is now R$ 117.87. You are already paying interest on the interest from the first month.
Jump to Month 6: The snowball has already gained speed. Following this logic, your debt would already be R$ 164.05.
End of 12 Months: At the end of a year, that initial debt of R$ 100 would have turned into R$ 269.13.
That’s why the installments seem endless, and the final amount is so disproportionate. With each passing month, a larger portion of your payment goes to cover the accrued interest, and a smaller portion goes to reduce the original debt. You work to feed the monster of compound interest.
Understanding this mechanic is liberating. It reveals that the problem is not taking credit, but rather the type of credit and the system in which it operates. A system designed to benefit from the passage of time, while your business needs speed.
The Alternative Model: Trading Debt for Asset
If the traditional banking model is based on creating a new debt for you, the alternative model, designed for the creative economy, operates from a radically different logic. The fundamental point you need to understand is this: receivables anticipation is not a loan.
A loan creates a future obligation from scratch, a debt that did not exist before. Anticipation, on the other hand, is nothing more than the sale of an asset that is already yours.
Think of it this way: a signed contract with a brand, a scheduled payment from YouTube, an invoice issued to an agency — this is not a vague promise. It’s a financial asset. It’s money that legally already belongs to you but is temporarily "stuck" in your client's 60- or 90-day payment cycle.
What does anticipation do? It allows you to sell that asset today and get the amount upfront, instead of waiting months. You are not creating debt; you are freeing up an asset. The company that anticipates, like DUX, buys your right to receive that future payment and takes on the waiting in your place.
This difference in nature reflects a drastically simpler and more transparent cost structure:
Fixed and Unique Cost (Discount): Instead of a soup of acronyms (interest, IOF, fees, insurance), the cost of anticipation is a single percentage, called a "factor" or "discount", applied to the value of your contract. This cost is transparent and fixed. You know from the very first second exactly how much you will receive and how much the operation cost. No surprises.
No Compound Interest: Since it’s not a loan, there’s no snowball effect of compound interest. The cost is calculated only once. There are no "interest on interest" running against you each month. The passage of time does not increase the cost of the operation.
No IOF Incidence: This is a critical technical advantage. The credit assignment operation, which is the legal basis for anticipation, is exempt from the IOF that burdens loans. It’s one less cost, making the operation structurally more efficient.
In summary, while the traditional model profits from your wait and from complexity, the anticipation model is designed to give you speed and clarity. You exchange a future cash flow and uncertain for immediate liquidity and execution power.
A Practical and Decisive Comparison
The theory is important, but nothing surpasses the clarity of practice. Let’s materialize the difference between the two models with a realistic scenario, starring a character who could be any of us:
The Character: Sofia, a freelance cinematographer. She has just received the opportunity to work on an amazing documentary but needs to invest R$ 20,000 in the rental of special lenses to ensure the quality the project requires. She needs the money quickly so as not to lose the job.
Scenario A: The Bank’s Path (Creating a Debt)
The Action: Sofia goes to her bank and requests a personal loan of R$ 20,000 to pay back in 12 months.
The Process: She faces days of uncertainty, sending proof of income (which, as a freelancer, is variable), filling out forms, and awaiting credit analysis, which does not fully understand her income source.
The Cost: The bank approves the credit with a Total Effective Cost (CET) of 8% per month. At the end of 12 months, the R$ 20,000 will amount to a total payment of approximately R$ 38,000.
The Result: Sofia gets the money for the lenses, but now she has a monthly debt of over R$ 3,100 for an entire year. Each new job she takes in the next 12 months already has a significant portion of the revenue committed to pay for the previous project. She feels the constant weight of this financial obligation.
Scenario B: The DUX Path (Liquidating an Asset)
The Action: Sofia has an invoice of R$ 25,000 issued to a production company for work already delivered, with a payment deadline of 90 days. This is her asset. She enters the DUX platform to anticipate that amount.
The Process: The process is 100% digital. She submits the contract and the invoice data. The analysis via artificial intelligence takes about an hour.
The Cost: The operation has a total and transparent cost of, let’s say, 9% on the contract value. The cost is R$ 2,250.
The Result: Within 24 hours, Sofia receives R$ 22,750 in her account. She uses R$ 20,000 for the lenses and still has some extra for other expenses. More importantly: she has no new debt. The transaction is completed. When the production company pays the R$ 25,000 in 90 days, the amount will go to DUX. Sofia is free, with her new project in hand and no future installment weighing on her decisions.
The Summary of the Confrontation:
Attribute | Bank Path | DUX Path |
Nature | Creation of Debt | Sale of Asset |
Real Cost | ~ R$ 18,000 | R$ 2,250 |
Bureaucracy | High, days/weeks | Minimal, hours |
Future Impact | Monthly debt for 1 year | No debt, no impact |
Result | Growth with burden | Growth with freedom |
The choice is no longer just about numbers. It’s about the kind of future you want to build for your business: a future of freedom and agility, or one chained to past debts.
Conclusion: The Power of Informed Choice
The journey through the world of credit may seem complex, but, as we have seen, it boils down to a fundamental choice. It’s not just a choice between the bank and an alternative but between two opposing philosophies: creating a debt that binds you to the past or liquidating an asset that accelerates your future.
For the creative economy professional, understanding this difference is as crucial as mastering their own craft. Financial literacy is no longer an "extra" or something to be delegated; it is a growth tool, a pillar of support for creative freedom. Knowing inside and out what CET is, the power of compound interest, and the logic of receivables anticipation is what allows you to sit at the negotiation table — whether with a bank or a client — in a position of power.
It is this new generation of creators and entrepreneurs, financially informed and strategic, that demands a financial infrastructure worthy of them. They no longer accept slowness, bureaucracy, and hidden costs as "normal". They demand clarity, speed, and partnership.
DUX was born to serve these creators. Not just as a platform, but as a partner in building stronger, faster, and above all, freer creative businesses. We believe that your focus should be on creating, not worrying about a snowball of debt.
The choice is yours. To continue in the traditional game, where time and complexity work against you, or to adopt a new model, where your own success finances the next step immediately. True creative independence begins when you take full control of your capital.
Do you have contracts or invoices awaiting payment? This amount is not a promise; it is an asset. Stop paying the abusive interest of banks and start using the capital that is already yours to grow.
