## Introduction

When it comes to managing finances, understanding the impact of interest on loans or investments is crucial. One common method of interest calculation is compound interest, and a monthly payment calculator compounded monthly becomes a valuable tool in navigating these financial waters. Whether you’re planning a loan repayment or estimating returns on an investment, this calculator can provide insights into your monthly obligations or potential gains.

## Formula:

The formula for calculating monthly payments compounded monthly is derived from the compound interest formula. The specific formula for calculating the monthly payment (PMT) is:

PMT = P×(1+r)n−1r(1+r)n

Where:

- $PMT$ is the monthly payment,
- $P$ is the principal amount (initial loan or investment amount),
- $r$ is the monthly interest rate (annual rate divided by 12 and expressed as a decimal),
- $n$ is the total number of payments or compounding periods.

Understanding this formula is essential for using the calculator effectively.

## How to Use?

Using the monthly payment calculator compounded monthly is straightforward:

**Input Principal Amount (P):**Enter the initial loan amount or investment principal.**Input Annual Interest Rate (r):**Input the annual interest rate, and the calculator will convert it into a monthly rate.**Input Number of Payments (n):**Specify the total number of payments or compounding periods.**Calculate Monthly Payment (PMT):**Hit the calculate button, and the tool will provide the monthly payment amount.

This calculator streamlines the process, saving you from manual computations and potential errors.

## Example:

Let’s consider an example: you take out a loan of $10,000 with an annual interest rate of 5%, and the loan is set to be repaid over 3 years (36 monthly payments). Using the formula, the monthly payment ($PMT$) would be calculated as follows:

PMT = 10000×(1+0.05)36−10.05(1+0.05)36

After evaluating this expression, the calculator reveals the monthly payment required.
