Formula Used in Loan Repayment Calculation

The calculator uses the standard amortization formula for monthly loan payments.

Monthly Payment Formula:

M=P×r×(1+r)n(1+r)n1M = \frac{P \times r \times (1 + r)^n}{(1 + r)^n - 1}M=(1+r)n−1P×r×(1+r)n​

Where:

  • M = Monthly payment
  • P = Loan principal (loan amount)
  • r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
  • n = Total number of months (years × 12)

Supporting Calculations

Total Payment:

Total Payment=M×n\text{Total Payment} = M \times nTotal Payment=M×n

Total Interest:

Total Interest=Total PaymentP\text{Total Interest} = \text{Total Payment} - PTotal Interest=Total Payment−P


Example Calculation

Let’s understand with a real example:

Loan Details:

  • Loan Amount: $150,000
  • Interest Rate: 5% per year
  • Loan Term: 30 years

Step 1: Convert Values

  • Monthly interest rate = 5 ÷ 12 ÷ 100 = 0.004167
  • Total months = 30 × 12 = 360

Step 2: Monthly Payment

Using the formula, the monthly payment is approximately:

👉 $805.23 per month

Step 3: Total Payment

805.23 × 360 = $289,882.80

Step 4: Total Interest

289,882.80 − 150,000 = $139,882.80

Factors That Affect Your Loan Repayment
