dobinda= suma · p% · timp ( se masoara in ani )
dobinda pe o luna = 1000 · 6% · 1luna/ 12luni = 6000 /100 · 1/12 = 5 lei
suma dupa o luna = 1000 + 5 = 1005 lei
dobinada ₂ = 1005 · 6% · 1/12 = 6030 / 1200 =5,025 lei
suma dupa doua luni = 1005 + 5,025 = 1010,025
dobinda ₃ = 1010,025 · 6% 1luna/ 12 = 6060,15 /1200 = 5,050125
suma finala = 1010,025 + 5,050125=1015,075125
