How does the calculation work?
The calculation of the additional amount follows a progressive structure, generally based on five-year periods.

| Length of Service | Percentage Increase |
|---|---|
| 5 years | 5% |
| 10 years | 10% |
| 15 years | 15% |
| 20 years | 20% |
| 25 years or older | 30% |

It is worth noting that some public companies adopt different criteria, such as Petrobras, which grants annual bonuses in addition to the traditional additional payment.
Impact on Career and Retirement

A civil servant who completes 25 years of service, for example, may have a salary increase of 30%, which represents a significant difference in the long term.
On the other hand, anyone who leaves public service before completing a five-year period loses the right to the benefit, reinforcing the importance of permanence.
