[1] Calculation method used: 30 / 360

Number of days in a month = 30

Number of days in a year = 360

[2] Simple interest, I
Calculation formula:

I =

(P × r × t) ÷ 360

I = Simple interest amount

360 = Number of days in a year

Simple flat rate interest.

Interest

When someone lends money to someone else, the borrower usually pays a fee to the lender. So the due interest is an amount of money paid or charged for the use of money or for borrowing money. The interest depends on:
1) the period length of the loan
2) the amount of money lent or borrowed (called principal)
3) the interest rate (the percentage of the principal charged as interest).
For example, for some bank deposits is not uncommon to pay an interest rate of 3.5% on the principal, annualy. That means that at the end of a one-year period the bank will repay not only the amount that was initially deposited, but also an additional amount, equal to the value resulting from the calculation: 3.5% × P, where P is the initial amount deposited, the principal.
Banks are also using these temporarily owned amounts of money by introducing them back into the cash flow circuit or are granting loans (for investments, for example) on which they are again charging interest.

The annual simple flat interest rate

The simple annual interest rate is simply the percentage of the principal charged as an interest for a period of one year, charged at the end of the period. An interest rate of r% tells us that for an amount of 100 (Dollar, Euro, Pound, Franc, Yen, ...), in one year, an amount of (r% out of 100) is earned as interest: I = r% × 100 units.
1. A deposit of an amount of money units P generates a one year simple interest of:
I = r% × P.
2. If the period for which the interest is calculated is two years, the interest accrued on a deposit of P money units is:
I = r% × P + r% × P = 2 × r% × P.
n. If the period for which the interest is calculated is n years, the interest accrued on a deposit of P money units is:
I = r% × P + r% × P + ... + r% × P = n × r% × P.
You can see that the amount accrued as interest, called simple interest, is added to the initial amount which earns interest, the amount borrowed or deposited, only at the end of the period of the deposit.
Simple interest is not an interest that earns interest on interest, as is the compound interest
