Example Loan Calculations Using the JavaScript Loan Calculator

Let’s explore practical examples using this loan calculator, showcasing how monthly payments and total costs are computed:

Example 1: Calculating a Personal Loan

Consider borrowing $20,000 with an annual interest rate of 5.2% over 8 years.

• Monthly interest rate: $$\frac{5.2}{100 \times 12} = 0.00433$$
• Total payments (months): $$8 \times 12 = 96$$
• Monthly payment: $$ M = P \times \frac{r(1 + r)^n}{(1 + r)^n – 1} $$ where:
  • $$P = 20,000$$ (loan amount)
  • $$r = 0.00433$$ (monthly interest rate)
  • $$n = 96$$ (number of payments)

Calculating M yields a monthly payment of approximately $262.67, and the total repayment over 8 years would be $25,218.32.

Example 2: Mortgage Loan Scenario

Imagine a home mortgage of $350,000 at 3.8% annual interest, repaid over 30 years.

• Monthly interest rate: $$\frac{3.8}{100 \times 12} = 0.003167$$
• Total payments (months): $$30 \times 12 = 360$$
• Monthly payment: Use the formula above to compute M.

Applying these inputs, your monthly payment will be approximately $1,633.25, while the total payment over the term sums up to nearly $587,970.

How the Loan Calculator Formula Works

The loan calculator applies the fixed-rate amortization formula to compute monthly payments:

$$ M = P \times \frac{r(1 + r)^n}{(1 + r)^n – 1} $$

Definitions:

• M = Monthly payment
• P = Principal loan amount
• r = Monthly interest rate (annual interest rate divided by 12 and converted to decimal)
• n = Total number of payments (loan term in years multiplied by 12 months)

This formula calculates an equal monthly payment amount that covers both principal and interest, ensuring full loan repayment by the end of the loan term.
