📈 Compound Interest

Discover the true power of compound interest. Enter the initial amount, monthly contribution, interest rate, and period — and instantly see how much your money will earn. Visualize the difference between what you invested and what the interest generated with a colored proportional bar. Supports monthly or annual rates, and periods in months or years.

🏆 First Million

What is your big financial goal? Define your target (the default is R$ 1,000,000), enter how much you have today and how much you can contribute per month — and the app calculates exactly how long it will take you to get there. Also see a comparative table

showing the estimated timeframe for 5 types of investment: Savings, Treasury Selic, CDB, REITs, and Stocks.

🏠 Rent or Finance?

The question every Brazilian asks themselves. Enter the property value, down payment, term, financing interest rate, equivalent rental value, and return on your investments — and the app simulates both scenarios month by month for the entire financing period. The result shows the total cost of each option, accumulated assets, and a clear verdict on which is most advantageous for your case.
