Formula Explained

The loan payment calculation uses the standard mortgage formula:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years multiplied by 12)

This formula calculates the fixed monthly payment required to pay off a loan with compound interest.

Worked Example

Let's calculate a loan with these parameters:

Loan amount: $200,000
Annual interest rate: 4.5%
Loan term: 30 years

Using the formula:

Monthly interest rate = 4.5% ÷ 12 = 0.00375

Number of payments = 30 × 12 = 360

Monthly Payment = $200,000 × (0.00375(1 + 0.00375)^360) / ((1 + 0.00375)^360 - 1)

Monthly Payment ≈ $1,073.64

Total interest paid over 30 years would be approximately $222,052.80, and the total cost of the loan would be $422,052.80.

What is the difference between fixed and variable rate loans?: Fixed rate loans have a consistent interest rate throughout the loan term, while variable rate loans adjust with market interest rates, which can change your monthly payment.
