About SimulaTudo

SimulaTudo is a free portal of financial calculators built to help people understand their finances: interest, investments, financing, salary and financial planning, focused on the Brazilian context.

We believe better financial decisions start with clear information. That's why every calculator comes with plain-language explanations, practical examples and FAQs — with no account required.

We are not a financial institution, we don't sell investment products, and we don't offer personalized advice. Our role is to help you run the numbers and understand the concepts behind them.

The project keeps evolving: new calculators and improvements are added regularly. If you spot an error or have a suggestion, we'd love to hear from you on our contact page.
