What is Prima de servicios?
The prima de servicios equals 30 days of salary per year worked and is paid in two equal parts: the first no later than June 30 and the second in the first 20 days of December.
If the worker did not work the full half-year, they receive the proportional part. It is calculated on salary plus the transport allowance (auxilio de transporte) where it applies.
In practice
A worker who earned $2,000,000 during the half-year receives around $1,000,000 of prima in June, and another part in December.
