# Monthly Payment Interest Calculator

## Introduction

Managing finances often involves dealing with loans and credit, whether it’s for a mortgage, car loan, or personal loan. One crucial aspect of these financial commitments is understanding the monthly payment, which includes both the principal amount and the accrued interest. To simplify this process, a Monthly Payment Interest Calculator comes in handy, providing a quick and efficient way to estimate your monthly financial obligations.

## Formula:

The calculation for the monthly payment involves a formula known as the loan payment formula or annuity formula. The formula is:

M = P×(1+r)n1r(1+r)n

Where:

• is the monthly payment.
• is the principal loan amount.
• is the monthly interest rate (annual rate divided by 12 and expressed as a decimal).
• is the total number of payments (loan term in months).

## How to Use?

Using the Monthly Payment Interest Calculator is a straightforward process. Follow these steps:

1. Enter Principal Loan Amount (P): Input the initial amount borrowed.
2. Enter Annual Interest Rate (r): Provide the annual interest rate on the loan.
3. Enter Loan Term in Years (n): Specify the total number of years for the loan term.
4. Calculate Monthly Payment (M): Click the calculate button to get the estimated monthly payment.

## Example:

Let’s consider an example:

• Principal Loan Amount (): \$50,000
• Annual Interest Rate (): 5%
• Loan Term (): 3 years

Using the formula, the monthly payment () would be calculated.

M = 50000×(1+0.05)3610.05(1+0.05)36

After solving this, you’ll get the monthly payment amount.
