Calculation History

    Introduction

    A Loan Repayment Calculator is a valuable financial tool that helps individuals and businesses determine the monthly or periodic payments required to repay a loan over a specified period. It plays a crucial role in financial planning, allowing borrowers to assess the affordability of loans and make informed decisions.

    The Basic Formula

    The fundamental formula behind a Loan Repayment Calculator is the amortization formula. This formula calculates the periodic payment required to fully repay a loan over a given period while considering the principal amount, interest rate, and loan term. The formula is as follows:

    PMT = P * (r * (1 + r)^n) / ((1 + r)^n – 1)

    Where:

    • PMT is the monthly payment or periodic payment.
    • P is the principal loan amount.
    • r is the monthly interest rate (annual interest rate divided by 12).
    • n is the total number of payments (loan term in months).

    Example Calculation

    Let’s consider an example to better understand how the Loan Repayment Calculator works. Suppose you borrow $10,000 with an annual interest rate of 5% for a 5-year term (60 months).

    1. Convert the annual interest rate to a monthly rate:
      r = 0.05 / 12 = 0.00416667
    2. Calculate the total number of payments:
      n = 5 years * 12 months/year = 60 months
    3. Apply the formula:PMT = 10000 * (0.00416667 * (1 + 0.00416667)^60) / ((1 + 0.00416667)^60 – 1)PMT ≈ $188.71

    So, your monthly payment to repay the $10,000 loan over 5 years at a 5% annual interest rate is approximately $188.71.
