As the applicants can leave the Centres and therefore the costs on them are only when they are physically present at the Centres, a unit was created to calculate the exact costs. The RFA calls it FPD – Physical Residence Day (“Fyzický pobytový den” in Czech), thanks to which it is possible to calculate the amount needed for one applicant per day physically present in the Centres; however not costs per applicant, as each applicant spends a different number of days there (so it is not possible to use it as unit of measure).<br />The calculation is performed as follows: for the entire monitored period (fiscal year) the numbers of physically present applicants are counted (these data are continuously monitored and recorded) and this number then divides the volume of costs incurred in a particular asylum facility (see a list at Clarification 4). With this calculation, we get the average cost per applicant for one day of his/her physical stay in the facility.
