Calcolo dell'aggiornamento del canone al 100%
Dividete il canone per il mese di fine dell'aggiornamento e moltiplicatelo per il mese di inizio dell'aggiornamento.
Per esempio: per sapere l'aggiornamento tra giugno 1999 e giugno 2000, la formula è
Canone non aggiornato / 1,0018 x 1,0284= Canone aggiornato al 100% indice Istat
Calcolo dell'aggiornamento del canone al 75%
E' un po' più difficile. Fate l'operazione precedente. Calcolate l'incremento avuto al 100%.
Moltiplicate questo incremento per 75 e dividetelo per 100. La formula è:
Canone aggiornato al 100% indice Istat - Canone non aggiornato = incremento al 100%
Incremento al 100% X 75/100= incremento al 75%
Canone non aggiornato + incremento al 75% = canone aggiornato
