Loan Calculator

Loan has become an essential part of our personal and business life in today's busy life. Buying homes, buying cars, the cost of higher education, or expansion of business, etc. are often needed for large sums of money that are not in hand. It is then that we borrow from banks or financial institutions.

But borrowing does not just mean getting money—it comes with the responsibility to return the money with interest within a certain time. The repayment figure and schedule are not always straightforward to follow.

The loan calculator helps us to do so properly. Now we will know what the loan calculator actually is and how it works.

What is a Loan Calculator?

The loan calculator is an online or offline tool. It helps the borrower easily calculate monthly installments (EMI), total interest, and total payable money. By providing some basic information, it calculates your loan repayment plan.

The specific inputs required are:

• Loan Amount (Principal): The total amount borrowed.

• Interest Rate: The APR (annual percentage rate) that represents the lender’s charge for the loan.

• Loan Term: The period over which the loan will be repaid.

• Payment Frequency: Monthly, quarterly, or yearly.

Based on this information, the calculator will find out your monthly installment and interest amount in seconds.

Loan EMI Formula

The standard formula used is:

EMI = [P × r × (1 + r)^n] ÷ [(1 + r)^n – 1]

Where:

• P = Loan amount (Principal)

• r = Monthly interest rate

• n = Number of monthly payments

Example Calculation

Suppose you are taking a $50,000 loan with an annual interest rate of 7.5% for 5 years.

• Loan Amount (P) = $50,000

• Annual Interest Rate = 7.5%

• Monthly Interest Rate (r) = 0.075 ÷ 12 = 0.00625

• Loan Term = 5 years = 60 months

Monthly Payment = $1,001.88

That means:

• Total repayment over 5 years = $60,112.80

• Total interest paid = $10,112.80
