Mandate calculator was advenced by Dániel Róna – with the help of Zombor Erdélyi -, commissioned by Medián polling company in 2009. The upgraded versions of the modell predicted the result of the 2010 parliamentary election based on the 2009 EP-election data and the results of the 2014 national election based on the 2010 national data. Both predictions proved to be precise: there were only 2 and 3 seats difference between the estimated and the actual results.

The mandate calculator algorithm and this website was developed by Bálint György Kubik. We made the source code of the mandate calculator publicly available on GitHub .
