Personal Loan Calculators: A Simple Guide with Easy-to-Understand Formula

Personal Loan


           Personal loans are a common way for people to manage various financial needs like consolidating debt or covering unexpected expenses. But before diving in, it’s important to know exactly how much you’ll be paying back. That’s where a personal loan calculator comes in handy.In the following discussion, we’ll unravel the essence of a personal loan calculator, elucidate its functionality, and furnish you with a straightforward formula for manual computation.

What is a Personal Loan Calculator?

 A personal loan calculator is like a digital tool that helps you figure out how much you’ll have to pay each month and in total when you borrow money. You just put in some numbers like the amount you want to borrow, the interest rate, and how long you’ll take to pay it back. Afterward, it reveals the amount you’ll need to pay each month and the total sum you’ll repay.

  1.    Loan Amount (P): This refers to the total amount borrowed from the lender.                                                                                            
  2. Interest Rate (r): The annual interest rate applied to the loan amount.                                                                                                    
  3. Loan Term (n): The duration over which the loan will be repaid, usually expressed in months.                                                          
  4. Monthly Payment (M): The fixed amount to be paid monthly towards the loan.                                                                             

Formula for Calculating Monthly Payment:

                The formula used by personal loan calculators to determine the monthly payment is as follows:


  • = Loan Amount                                                                                                                                                                                                           
  • = Monthly Interest Rate (annual interest rate divided by 12)                                                                                                                                
  • = Total Number of Payments (loan term in months)                                                                                                                                              

            Understanding the Formula:

          The formula may look complex at first glance, but it’s relatively straightforward. Here’s a simplified explanation:

  1. First, add 1 to the monthly interest rate.
  2. Then, raise the result to the power of the total number of payments.
  3. Multiply the loan amount by the monthly interest rate.
  4. Multiply the result by the value obtained in step 2.
  5. Divide the result by the value obtained by subtracting 1 from the value obtained in step 2.

This calculation yields the fixed monthly payment required to repay the loan in full over the specified period.


Using a Personal Loan Calculator:

Using a personal loan calculator is as easy as pie:

You type in the amount of money you want to borrow.
Then, you enter the yearly interest rate that the lender is charging.
