What is Interest?

Interest; It is the money received in return for the use of the money lent to a bank or similar institution to operate the money for a certain period of time. Loan and Deposit rates are the two most well-known types of interest.

Loan interest is the amount of money borrowed from a bank or similar institutions for a need, added to the principal according to the maturity received. It is money paid in exchange for the operation of money.

The loan interest is calculated by applying interest again to the remaining principal in each payment period. For this, the principal amount and the interest rate are multiplied and the taxes of the country where you will use the loan are added. Generally, the first months of your loan debt are taken as 90% principal 10% interest debt by banks. This ratio is then balanced.

Interest rates vary according to the monetary policy of the countries.

How to Calculate Compound Interest Example
Example - 1:

What will be the principal value of the $1000 deposited in the bank at an annual interest rate of 10%, at the end of the 3rd year, with the compound interest method?

Solution : P = $1000 r = 10 / 100 n = 3 yılA = 1000 x (1 + 0.1)3

The total money at the end of year 3 is calculated as $1331.

Example - 2:

An investor invested $32000 in compound interest for 5 years at an annual interest rate of 30%. How much money does the investor receive at maturity?

Solution : P = $32000 r = 30 / 100 n = 5 yılA = 32000 x (1 + 0.3)5 = $118.813,76

The total amount that the investor will receive at the end of the 5th year is $118,813,76.
