How much of my home loan is coming from a bank, how much it goes back? 
Ditto mhoran_psprep.  I'm not quite sure what you're asking. Where does the money come from? When someone starts a bank, they normally get together a bunch of investors -- perhaps people they know personally, perhaps they sell stock -- to raise initial capital. But most of the money in the bank comes from depositors. Fundamentally, what a bank does is take money from depositors and loan it to borrowers. (Banks also borrow money from other banks and from the government.) They charge the borrowers interest on the loan, and they pay depositors interest on their deposits. The difference between those two interest rates is where the bank gets their profit. Where does the money go when you pay it back? As mhoran_psprep said, some of it goes to pay interest to the depositors; some of it goes to pay the bank's expenses like employee salaries, cost of the building, etc; and some of it goes as profit to the owners or stockholders of the bank. If you're thinking, "Wow, I'm paying back a whole lot more than I borrowed", well, yes. But remember you're borrowing that money for 20 or 30 years. The bank isn't making very much money on the loan each year that you have it -- these days something like 4 or 5% in the U.S., I don't know what the going rates are in other countries.
