About giving loans given to Others

for e.g. If i give 1T SC$ to someone for 10 months. so when do i get Interest for that? Do i get 12% every month? if that so then all together its 120%.
Or i only get 12% after 10 months. thats all i have to ask. sorry if i made any mistakes in typing , i am still learning lol :p

its 12% interest per real life year. so if you lend 1T SC$ to someone ingame repeadedly for a real life year you'll get 120B interest meanwhile. So depending on the world you play you get about 50M - 100M per game month interest from those 1T you loaned
