Introduction

Calculating loan repayment time is a crucial aspect of financial planning. To simplify this process, we’ve created a user-friendly Loan Repayment Time Calculator using HTML and JavaScript. This article will guide you through using the calculator, explain the formula behind it, provide examples, address frequently asked questions, and conclude with the importance of financial planning.

How to Use

1. Enter the loan amount in the designated input field.
2. Input the annual interest rate.
3. Specify the monthly payment you can afford.
4. Click the “Calculate” button to get the estimated loan repayment time.

Formula

The formula used in the calculator is the time value of money equation:

Loan Repayment Time (in months)=log(1+r)−log(1−AP∗r​)​

Where:

• $P$ is the principal loan amount.
• $r$ is the monthly interest rate (annual rate divided by 12 and then by 100).
• $A$ is the monthly payment.

Example

Suppose you have a loan of $10,000 with an annual interest rate of 5%, and you can afford a monthly payment of $200.

Loan Repayment Time=log(1+0.05/12)−log(1−20010000∗0.05​)​

Calculating this yields the loan repayment time in months.
