    What is Loan Repayment?

    Loan repayment refers to the process of returning borrowed money to a lender or creditor according to the terms and conditions outlined in a loan agreement.

    When an individual, business, or organization borrows funds, they are required to repay the borrowed amount, along with any interest or fees, over a specified period. Loan repayment is a fundamental aspect of borrowing and involves making regular payments until the entire loan is paid off.

    All Formulae Related to Loan Repayment Calculator

    Here are the key formulae related to a loan repayment calculator:

    1. Monthly Payment (Fixed-Rate Loan):
      • Formula: M = P * (r * (1 + r)^n) / ((1 + r)^n - 1)
      • Variables:
        • M: Monthly payment
        • P: Principal loan amount
        • r: Monthly interest rate (annual interest rate divided by 12 and expressed as a decimal)
        • n: Total number of monthly payments (loan term in years multiplied by 12)
    2. Total Interest Cost:
      • Formula: Total Interest = (M * n) - P
      • Variables:
        • Total Interest: Total interest paid over the life of the loan
        • M: Monthly payment
        • n: Total number of monthly payments
        • P: Principal loan amount
    3. Loan Amortization Schedule:
      • Loan amortization schedules break down each payment into principal and interest components, allowing borrowers to track how the loan is being paid off over time.
      • The formulas to calculate the interest payment, principal payment, and remaining balance for each month are as follows:
        • Interest Payment (I): I = P * r
        • Principal Payment (Pp): Pp = M - I
        • Remaining Balance (Rb): Rb = P - Pp
      • These calculations are performed for each month of the loan term, with the principal decreasing and the interest portion decreasing over time.
    4. Loan Payoff Time (for early repayment):
      • Formula: Payoff Time = -(n / ln(1 - (P * r / M)))
      • Variables:
        • Payoff Time: The number of months it takes to pay off the loan early
        • n: Total number of monthly payments
        • ln: Natural logarithm
        • P: Principal loan amount
        • r: Monthly interest rate (annual interest rate divided by 12 and expressed as a decimal)
        • M: Increased monthly payment for early repayment
