    3 Number of Calculations Used Today


    P = \frac{L \cdot \frac{r}{12}}{1 - (1 + \frac{r}{12})^{-n}}


    • P: is the monthly payment
    • L: is the loan amount
    • r: is the annual interest rate (expressed as a decimal)
    • n: is the number of payments (usually the total number of months)


    How is the Monthly Loan Payment Calculated?

    The loan monthly payment is calculated based on factors such as the loan amount, interest rate and term length. Basically, it is determined using the monthly payment on loan (PMT) formula. This formula is used to calculate the monthly payment amount and is as follows:

    PMT = \frac{P \times r \times (1 + r)^n}{(1 + r)^n - 1}

    Here you are:

    • P: loan amount
    • r: monthly interest rate
    • n: represents the loan maturity (in months)

    In this formula, the payment amount (PMT) represents the fixed amount to be paid each month. This formula is used to calculate the amount of monthly installments needed to repay the entire loan. Also, some considerations to take into account in this formula:

    • If the interest rate is given in annual terms, the annual interest rate must be divided by 12 to find the monthly interest rate.
    • The maturity period should also be expressed in months.

    This formula is a commonly used method for calculating monthly loan payments. However, in practice, online calculators or financial calculator tools can be used to make such calculations, as these tools usually provide faster and more accurate results.

    What is a Loan Payment?

    Loan repayments are periodic payments made to repay the loan amount when a loan or debt is taken out. These payments are usually made at regular intervals and continue throughout the loan term. A loan payment usually consists of principal and interest. Principal represents the original debt of the loan amount, while interest debt refers to the additional cost calculated on the loan amount.

    Loan payments are determined by the loan amount, interest rate and maturity period and are made in installments. These payments may vary in accordance with the borrower’s financial situation and are scheduled to be made without unduly burdening his or her income in a given period.

    Loan Repayment Calculation Methods

    Loan payment calculation methods refer to different mathematical formulas and calculation techniques used to determine loan installments. Here are some commonly used loan payment calculation methods:

    1. Simple Interest Method: In this method, interest, calculated at a fixed interest rate applied to the loan amount, is added to the principal and remains constant for the entire loan term. The amount payable in each installment is the sum of the principal and interest.
    2. Compound Interest Method: In this method, interest calculations are added to the principal throughout the loan term. That is, the amount payable in each period is the sum of the principal amount and interest calculated on the remaining principal. This method is generally more common and provides a more accurate calculation.
    3. Amortization Table Method: In this method, the principal and interest components of each installment over the loan term are shown separately. It is clear how much of each installment payment goes to principal and how much goes to interest. This method provides a detailed analysis of installment payments.
    4. Fixed Installment Method: In this method, the installment amount remains constant throughout the loan repayment. However, the principal and interest rates may change within the amount paid in each installment. In this method, although the installment amount remains the same throughout the repayment period, the principal and interest amounts may change depending on the interest rates.

    Which of these methods to use may depend on the lender’s policies, the borrower’s preferences and the financial status of the loan repayment.

    Simple Loan Payment Calculation Example

    You want to get a loan of 10,000 USD from the bank. The bank charges an annual interest rate of 10% for this loan and the loan term is 12 months. In this case, we can calculate how much you need to pay each month.

    1. Calculate Total Repayment Amount:

    The total repayment amount is equal to the sum of the loan amount and the interest rate:

    Total Repayment = Loan Amount + (Loan Amount * Interest Rate)

    Total Repayment = 10,000 USD + (10,000 USD * 0.10) = 11,000 USD

    2. Calculate Monthly Payment Amount:

    We divide the total repayment amount by the maturity period (12 months):

    Monthly Payment = Total Repayment / Maturity Period

    Monthly Payment = 11,000 USD / 12 = 916.67 USD (approximately)

    The amount to be paid to the bank each month will be approx: 916.67 USD. This payment is calculated by dividing the loan amount with interest equally over 12 months.

    Considerations in Loan Repayment Calculation

    Here are some important points to consider when calculating loan repayment:

    Interest Rate: Loan payments are usually determined by the interest rate applied to the loan amount. It is important to calculate and take into account the interest rate correctly.

    Loan Amount: When calculating the loan payment, the loan amount must be determined correctly. Incorrect calculation of the loan amount may cause the payment plan to be incorrect.

    Maturity Period: The loan term determines how long the loan payments will be made. Short-term loans usually result in higher monthly payments, while long-term loans may result in lower monthly payments.

    Additional Costs: Additional costs (such as insurance premiums or processing fees) may need to be taken into account when calculating loan payments.

    Reviewing the Payment Schedule: When planning loan payments, it is important to carefully review the payment schedule and assess whether the loan payment amounts fit within the budget.

    Tax and Legal Obligations: It is important that loan payments comply with tax and legal regulations. The taxation process and tax rates should be considered.

    Flexibility and Adjustments: When planning loan repayments, flexibility should be provided for unforeseen circumstances and the repayment schedule should be adjusted when necessary.
