Example Calculation

Let’s take an example to understand how this calculator works:

  • Loan Amount: $10,000
  • Annual Interest Rate: 5%
  • Loan Term: 24 months

Step 1: Convert annual interest rate to monthly:
Monthly Rate = 5% ÷ 12 = 0.004167

Step 2: Calculate Monthly Installment using the formula:Monthly Installment=Principal×Monthly Rate1−(1+Monthly Rate)−Months\text{Monthly Installment} = \frac{\text{Principal} \times \text{Monthly Rate}}{1 - (1 + \text{Monthly Rate})^{-Months}}Monthly Installment=1−(1+Monthly Rate)−MonthsPrincipal×Monthly Rate​

= 10,000 × 0.004167 ÷ (1 − (1 + 0.004167)^−24)
≈ $438.71

Step 3: Calculate Total Payment:
Total Payment = 438.71 × 24 ≈ $10,529.04

Step 4: Calculate Total Interest:
Total Interest = 10,529.04 − 10,000 ≈ $529.04

So, for a $10,000 loan at 5% annual interest over 24 months, your monthly payment is $438.71, total repayment is $10,529.04, and total interest is $529.04.
