Simulation Details How Investing R$ 1,000 Monthly in Nubank’s Boxes Yields Over 1, 5, 10, 15, and 20 Years.

Investing every month is a way to build wealth in the long run. Nubank’s boxes, which yield 100% of the CDI, have become an alternative for those looking for something beyond savings accounts.

A video from the channel Pipoco Investidor shows practical simulations of how monthly contributions of R$ 1,000 can generate significant amounts over periods ranging from 1 to 20 years.

Every month, the invested money earns interest, and this interest also starts generating new earnings, creating the so-called “interest on interest”.

This snowball effect makes a difference when looking at longer time frames.

12-Month Investment

The simulation starts with a short-term scenario, that is, 12 months.

Those who invest R$ 1,000 per month spend a total of R$ 12,000 in a year. During this period, the gross yield reaches R$ 798.96.

As the income tax for this period is 17.5%, there is a deduction of R$ 139.82.

Therefore, the net profit is R$ 659.14. In the end, the investor will have R$ 12,659.14, adding the invested amount plus the net earnings.

This difference may seem small, but it serves to demonstrate how even in one year it is possible to achieve returns higher than those of savings accounts.

Moreover, it is worth noting that Nubank’s boxes offer daily liquidity and are protected by the Credit Guarantee Fund, factors that enhance the security of the investment.

Five Years of Contributions

When the period is extended to 5 years, the results change significantly.

In 60 months, the total contribution reaches R$ 60,000. The gross yield during this period amounts to R$ 26,124.

After deducting the 15% tax, which amounts to R$ 3,918, the net earnings stand at R$ 22,206.

Thus, at the end of five years, the investor’s total balance will be R$ 82,206.

The most important point here is to realize how compound interest starts to take effect. Each month of investment reinforces the accumulated balance, which, in turn, continues to earn more and more.

Ten Years and the Effect of Compound Interest

The video highlights that, in 10 years, the difference is even greater. The amount invested during this period is R$ 120,000. The gross yield reaches an impressive R$ 138,600.

After a tax deduction of R$ 20,790, the net earnings amount to R$ 117,810. In the end, the investor accumulates R$ 237,810.

Therefore, from this period onwards, the power of compound interest becomes evident.

With every monthly investment of R$ 1,000, not only does the capital grow, but the monthly earnings also increase, accelerating the total growth.

Fifteen Years of Investment

Over a horizon of 15 years, the simulation becomes even more attractive.

In total, R$ 180,000 is invested. The gross yield reaches R$ 424,000. After deducting the tax of R$ 63,600, the net earnings amount to R$ 360,400.

Thus, the final balance reaches R$ 540,400.

Furthermore, it is clear that time is a powerful ally for the investor.

Over the years, the snowball of compound interest grows rapidly, something that is not noticed in shorter time frames.

Twenty Years to Become a Millionaire

The most impressive result appears in the 20-year simulation.

With monthly contributions of R$ 1,000, the total amount invested is R$ 240,000.

The gross yield reaches R$ 1,055,000. After the tax deduction of R$ 158,000, the net earnings are R$ 897,000. Therefore, at the end of 240 months, the investor’s balance reaches R$ 1,137,363.42.

The most important takeaway, according to the video’s author, is to realize that, regardless of the economic situation, the 20 years will pass.

The difference is that by maintaining discipline in contributions, it is possible to become a millionaire solely through compound interest.

Discipline as a Key Factor

The video reiterates that many people still leave money idle in savings accounts or spend without planning. However, investing in products that yield 100% of the CDI, like Nubank’s boxes, can make all the difference.

It also reminds viewers that there are free compound interest calculators available online, but provides its own table for a symbolic price of R$ 5 for those who wish to use it.

The focus, however, is not to sell the table but to raise awareness about the importance of long-term investment.

Therefore, those who invest R$ 1,000 per month in a product with a yield of 100% of the CDI, like Nubank’s boxes, can reach over R$ 1 million in 20 years.

This requires discipline, patience, and a focus on the long term.

While many prefer to spend money in the present, the simulation shows that the decision to invest can ensure a more comfortable financial future.
