To my students and anyone who wants to learn about simple interest.

1. Simple Interest
By Hector Castellanos

2. Amount of money borrowed from anywhere is known as the principal. The
institution would then charge an amount/sum on lending out the money. The
amount charge is calculate on a certain percent per annum or rate of interest
(rate per cent per annum). This is simple interest only if the principal in the
calculating interest, remains the same each year during the loan period. So
amount to be repaid are:
(a)amount borrowed (principal) and
(b)interest payable on the loan.

3. Simple Interest Equation
P = Principal
R = Rate per cent per annum
T = Time in years
I = Interest

4. Mr. Esquivel makes a loan of $12,000 at a local bank at a simple interest rate of 5% per
annum for 4 years.
(a)Calculate the simple interest payable?
(b)Calculate accruing amount of the loan.
(c)Calculate the monthly instalments.
Facts:
Principal = $12,000
Rate = 5%
Time = 4 years
Interest = ?
(a) Equation Interest payable (b) Accruing amount (c) Monthly instalment
A = P + I
A = $(12,000 + 2,400)
A = $14,400
I = $2,400.00
