The amount of interest paid is normally calculated on which of the following?
A
The present value of an annuity
B
The sum of principal and interest
C
The total amount of all future payments
D
The principal amount
Verified step by step guidance
1
Understand the concept of interest: Interest is the cost of borrowing money, typically calculated as a percentage of the principal amount over a specific period.
Identify the principal amount: The principal is the original sum of money borrowed or invested, excluding any interest or additional charges.
Recognize that interest is calculated based on the principal amount: The formula for simple interest is \( I = P \times r \times t \), where \( I \) is the interest, \( P \) is the principal, \( r \) is the interest rate, and \( t \) is the time period.
Clarify why other options are incorrect: Interest is not calculated on the present value of an annuity, the sum of principal and interest, or the total amount of all future payments. These are different financial concepts and do not directly determine the interest calculation.
Conclude that the correct basis for calculating interest is the principal amount, as it is the foundation for determining the cost of borrowing or earning interest.
