A small manufacturing business owner reads a translated pricing guide or watches a video by an American expert and tries to follow the formula step by step. Halfway through, the numbers in the spreadsheet do not add up. It is not a calculation error. The method was designed for another country, with a different tax burden built into prices, a different level of informality among competitors, a different cost of capital, and a different pace of input cost adjustments—and that is precisely what the imported guide does not cover, because its author never had to deal with it.
That is no reason to dismiss markup and margin. The formula is universal: in any country, price is cost plus something. What changes from one place to another is what goes into each of those figures. Anyone who assumes the inputs travel with the formula learns otherwise in the first quarter.
Four factors account for nearly the entire gap between the textbook price and one that works in the Brazilian market: taxes already built into the price, competitors that do not bear the same costs, payment terms as a cost of capital, and inputs whose prices change before the product reaches the shelf.
The tax built into the price, not added on top
Many translated pricing guides treat tax as something added later at checkout, with no impact on margin calculations. In Brazil, ICMS, PIS, COFINS, and, in many cases, tax substitution are built into the selling price—the customer does not see a separate tax line as they would on a U.S. invoice with sales tax itemized. This means the markup applied to cost must leave room for taxes, or the margin that looked secure on paper will vanish when the taxes are paid.
The impact becomes clear when you look at the numbers. A product costs R$ 50 to make. The company applies a 35% markup to the cost (price = cost × (1 + markup)), arriving at R$ 67.50 and expecting a gross profit of R$ 17.50. But that selling price includes 18% in taxes—a plausible combination of ICMS and PIS/COFINS for much of the retail sector. That takes R$ 12.15 out of the profit. After paying the cost and taxes, only R$ 5.35 remains—less than a third of what the original calculation promised. The markup formula was not wrong. The mistake was what it left out: tax is not an expense paid from whatever remains; it is part of the price from the very first calculation.
The competitor that doesn't bear the same cost
A competition-based pricing method implicitly assumes that every business in the market has a similar cost structure, including payroll taxes, invoicing, and tax payments. In Brazil, a significant share of small competitors operate informally, without many of these obligations. This gives them a cost advantage that formal businesses do not have and should not try to match.
This creates a particular trap for businesses that cannot set their own prices—known as price takers. They need to match the market price to avoid losing customers, but if their benchmark market includes informal competitors, the “technically correct” price calculated by a formal business may fall outside the range customers are used to paying. The answer is not to sink to the same level. Instead of comparing prices alone, compare what each business delivers for that price: a warranty, an invoice, delivery times, and support. You will never match the price of a competitor that does not pay taxes, but you can differentiate your offer.
Payment terms are a cost of capital, not a courtesy
Pricing guides from abroad often treat price as a single figure set at the time of sale. In Brazil, however, offering payment terms of 30, 60, or 90 days is common, and the cost of financing those terms is significant when the country’s interest rates are among the highest in the world. In practice, every additional day granted to the customer is an interest-free loan from the company. That cost must be built into the price rather than deducted from the margin at the end of the month as if it were just another finance expense.
A simple way to account for this is to add the cost of capital for the payment term—calculated using the company’s own borrowing rate—to the cost before applying the markup. A company that sells on 60-day terms without doing this calculation is unknowingly absorbing the bank’s financing cost into its margin—and only realizes it when cash flow gets tight, not when setting the price.
The input whose value changes before the product leaves the factory
Input cost inflation and exchange rate fluctuations affect every economy, but in Brazil they have historically moved faster than the price review cycle at many small businesses. A pricing method designed for a market with low, stable inflation implicitly assumes that the cost calculated today will still apply when the product is sold. That assumption fails more often here than many translated pricing guides would suggest.
In practice, how often you review prices matters just as much as the formula you use to calculate them:
- review the cost of key inputs before each production batch, not just at month-end;
- separate fixed costs from variable costs in the spreadsheet, so that changes in input costs do not require recalculating the entire cost structure;
- maintain a safety margin in the markup to account for the gap between the measured cost and the actual cost on the date of sale.
What changes isn't the formula, but what goes into it
Markup on cost and margin on price are calculated the same way anywhere in the world. The distinction between them is also a common source of confusion in any pricing guide, whether local or international: price = cost × (1 + markup) is not the same calculation as price = cost ÷ (1 − margin). Treating the two as interchangeable is enough to produce the wrong price before taxes or exchange rates even enter the picture.
What really separates a price that works abroad from one that works here is not the formula itself, but the list of what counts as a cost and which competitors serve as benchmarks. Embedded taxes, informal competitors, the cost of financing payment terms, and the pace of input cost adjustments do not appear as variables in a guide written for a different tax environment and interest rate—and ignoring them is not a minor detail that can be fixed later. It is the difference between the price shown in the spreadsheet and the cash left at the end of the month. Anyone who uses REVEMA’s selling price calculator to run this calculation already has an advantage: in most cases, what is missing is not a calculation tool, but a clear understanding of exactly which local variables to enter before trusting the number it returns.
The imported playbook is not useless. It is incomplete by design because it was written to solve a problem in a different market. Adapting it is not about translating the formula—it means replacing each variable with what actually happens in the Brazilian market, item by item, until the calculated price stops being a work of fiction and becomes a number that can withstand the real competition, taxes, and interest rates in the country where the business operates.
