What happens to money after you deposit it?

What happens to a $10 bill after you deposit it in your savings account? Does the

bank teller take it to a vault and put it into a separate compartment or cubbyhole

marked with your name and account number? No.

The bank begins by adding $10 to the amount that is already in your account (your

existing balance). Your $10 deposit and your new balance are then recorded in your

bank book and in the bank’s computer system. The $10 bill you deposited is mixed in

with all the other cash your bank receives that day.

When you and other customers deposit money in a bank, the bank “puts most of it to

work.” Part of the money is set aside and held in reserve, but much of the rest is

loaned to people who need to borrow money in order to buy a house or a car, expand a

business, buy farm equipment, or do any of the other things that require people to

borrow money. Of course, banks do not lend money just to provide a service. They do

it to make money. Here’s how it works.

When you keep your savings in a bank, the bank pays you extra money, which is called

interest. The interest is added to your account on a regular basis, usually once a

month.

Let’s say a bank pays its depositors interest of 3 percent a year on their savings.

In simple terms, that means if you keep $100 in your savings account, the bank will

add $3 to your account balance during the course of a year.

But, there is another side to interest. When someone borrows money from a bank, the

bank charges interest, and it charges borrowers a higher rate than it pays savers.

For example, it might pay savers 3 percent and charge borrowers 8 percent. The

difference, 8 percent minus 3 percent, goes to the bank. Charging interest on loans

is one of the main ways for a bank to make money.

The rate of interest a bank charges depends largely on two things:

• how many people want to borrow money, and

• how much money banks have available to lend.

If a bank has plenty of money to lend, and the demand to borrow money is not

particularly strong, interest rates will tend to be low in order to attract

borrowers. But when banks have a smaller amount of money to lend, and the demand to

borrow is fairly strong, interest rates will rise. As a depositor, you want interest

rates to be high, but as a borrower, you want them

to be low. When it comes to paying interest on savings deposits, there usually isn’t

a big difference between banks. They pay just enough to stay competitive with one

another and attract depositors. So, if one bank is offering a much better (higher)

rate than most other banks, try to find out why. And remember the old saying: If

something sounds too good to be true, it

probably is.
