Loan Calculator: Calculate Your Monthly Payments Easily (2025 Guide)

When applying for a loan—whether it’s a personal loan, mortgage, car loan, or student loan—understanding your monthly payments is critical. A loan calculator makes this process simple by helping you estimate your EMI (Equated Monthly Installments), interest cost, and total repayment amount.

In this article, we’ll explain what a loan calculator is, how it works, and why you should use one before taking out a loan in 2025.

What is a Loan Calculator?

A loan calculator is an online tool that allows borrowers to estimate:

• Monthly payments (EMI)

• Total interest cost

• Total repayment amount

It uses three main inputs:

1. Loan Amount

2. Interest Rate

3. Loan Term (tenure)

By adjusting these factors, you can quickly see how your payments will change.

Formula Behind Loan Calculators

Most loan calculators use the EMI formula:

EMI=P×r×(1+r)n(1+r)n−1EMI = \frac{P \times r \times (1 + r)^n}{(1 + r)^n – 1}EMI=(1+r)n−1P×r×(1+r)n​

Where:

• P = Loan amount

• r = Monthly interest rate (annual interest ÷ 12)

• n = Number of months

Example:

• Loan = $20,000

• Interest = 6% annually

• Term = 5 years (60 months)

Your monthly payment would be approximately $386.66.
