Example :


PUBLIC SUB mensualite()

DIM duree AS Integer
DIM periode AS Integer  
DIM taux AS Float    
DIM montant AS Integer
DIM tm AS Float
DIM mensualite AS Float


montant = 10000
taux = 0.05
duree = 60
periode = 12 '12 mensualité par an


tm = (1 + taux) ^ (1 / periode)
mensualite = Round(montant * (tm - 1) / (1 - (tm) ^ - (duree)), -10)

Message.Info("la mensualité est de " & mensualite)
