Simulation Shows How Much Investing R$ 1,000 a Month in Nubank’s Caixinhas Yields for 5, 10, and 15 Years Based on the Current Rate of 100% of the CDI.
Starting to invest early can make a big difference in the long run, which is why we show how much it yields.
A simulation made with the “Emergency Reserve” caixinha from Nubank showed how monthly contributions of R$ 1,000 grow over time.
As shown by the channel Pipoco Investidor, the investment yields 100% of the CDI, which is currently at 14.65% per year, or about 1.15% per month.

Simulation for 5 Years of Investment; See How Much It Yields
If a person invests R$ 1,000 every month for 5 years, the total invested will be R$ 60,000. This is the amount that will come out of pocket over the 60 months.
Considering the gross return of the caixinha, the total amount accumulated with interest will be R$ 25,611 during this period.
However, it is necessary to consider the income tax. Since the investment is long-term, a 15% tax will be charged on the earnings. In this case, the deduction will be R$ 3,841.
With the deduction, the net return will be R$ 21,769. Adding this amount to the total invested, the final amount at the end of 5 years will be R$ 81,769.
Result After 10 Years of Contributions
By doubling the time, the difference in earnings is even greater. With a monthly investment of R$ 1,000 for 10 years, the total amount invested will be R$ 120,000.
With compound interest, the gross return reaches R$ 135,202. However, with the income tax deducted, which in this case will be R$ 20,280, the net return will be R$ 114,922.
Thus, the final accumulated amount at the end of 10 years will be R$ 234,922. In other words, the investor will have invested R$ 120,000 and will end up with almost double.
Significant Accumulation in 15 Years
In the longest simulation, with monthly contributions of R$ 1,000 for 15 years, the total amount invested reaches R$ 180,000.
The gross return in this situation is impressive: R$ 411,151. This result occurs due to the effect of compound interest over time. However, the income tax will also be higher: R$ 61,672.
After this deduction, the net return will be R$ 349,479. Adding this to the invested amount, the final amount will be R$ 529,479.
Table with the results of the simulation of investing R$ 1,000 a month in Nubank’s Caixinhas (Emergency Reserve, 100% of the CDI)
| Period | Total Invested | Gross Return | Income Tax (15%) | Net Return | Final Amount |
|---|---|---|---|---|---|
| 5 years | R$ 60,000 | R$ 25,611 | R$ 3,841 | R$ 21,769 | R$ 81,769 |
| 10 years | R$ 120,000 | R$ 135,202 | R$ 20,280 | R$ 114,922 | R$ 234,922 |
| 15 years | R$ 180,000 | R$ 411,151 | R$ 61,672 | R$ 349,479 | R$ 529,479 |
The More Time, the Greater the Return
The numbers clearly show how time is an essential factor in the growth of investments.
In 5 years, the accumulated amount exceeds R$ 80,000. In 10 years, it surpasses R$ 230,000. In 15 years, the total exceeds R$ 500,000.
The secret lies in compound interest, which increasingly increases the return on the invested capital.
The effect is cumulative: the earnings begin to generate new earnings, creating a positive growth cycle.
Simulation Tool
For those who want to make their own simulation, there is a table available with all the calculations ready.
The spreadsheet is available for R$ 5, as a way to support the content creator.
With it, you can adjust the monthly investment amount and the length of the investment.
The tool helps visualize how much can be accumulated over the years based on different scenarios.
Importance of Starting Early
Starting to invest as soon as possible allows compound interest to work for a longer time. This maximizes gains, even if the monthly investment amount is modest.
The caixinha used in the simulation is geared towards emergency reserve, with immediate redemption and a yield of 100% of the CDI.
This feature allows you to use the money in case of need without losing the yield from the period.
Those who start with R$ 1,000 a month and maintain discipline over time can achieve surprising results. The numbers from the simulation show that the monthly effort can yield more than R$ 500,000 in 15 years.
Even considering the tax, the gain is significant. Therefore, investing consistently, even with small amounts, can be a great step towards achieving financial goals in the future.
