Methods to Calculate Interest on a Loan
There are several methods to calculate the interest on a loan, and the most common ones are:
1. Simple Interest: This method calculates interest based on the principal amount and the interest rate over a specific period. The formula for simple interest is:
Interest = Principal × Rate × Time
2. Compound Interest: Compound interest is calculated on the principal amount and the accumulated interest. The formula for compound interest is:
A = P(1 + r/n)^(nt)
Where:
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for
3. Effective Annual Rate (EAR): The EAR is the interest rate that is actually earned or paid on an investment or loan, taking into account the effect of compounding. The formula for EAR is:
EAR = (1 + r/n)^n – 1
Where:
r = the nominal annual interest rate (decimal)
n = the number of times that interest is compounded per year
