About this tool
Three questions every small company in Brazil asks: how much Simples Nacional tax (DAS) do I pay this month, what price covers my costs, taxes and margin, and how much do I need to sell to stop losing money. Here the three calculators live together: Simples Nacional (DAS), price and markup, and break-even point. Choose the tab at the top; the effective DAS rate moves into the price, and the price into the break-even. The Simples uses the annexes of LC 123/2006 as rewritten by LC 155/2016. These are estimates for planning, not a substitute for an accountant.
How to use it
- 1 Choose at the top: Simples Nacional, price and markup, or break-even point.
- 2 In the Simples tab, type the revenue of the last 12 months, this month's revenue and the annex of the activity.
- 3 In the price tab, type the unit cost and the shares of the price for taxes, expenses and margin.
- 4 In the break-even tab, type the fixed costs; the price and the variable costs come from the price tab.
Frequently asked questions
Are the values I type saved or sent anywhere?
No. Everything is worked out in your browser. Nothing goes to a server, nothing is saved and nothing stays in the page address; only the link you choose to copy carries the values.
Why does the effective rate differ from the rate in the table?
Each band of an annex has a nominal rate and an amount to deduct. The effective rate is (RBT12 × nominal rate − amount to deduct) ÷ RBT12, so it grows smoothly with revenue instead of jumping at each band.
Is the margin the same as the markup?
No. The margin is a share of the selling price; the markup is the factor applied to the cost. A 10% margin on the price is more than 10% over the cost.
