Formula Used

The monthly payment (PMT) for a loan is calculated using the following formula:

PMT = 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 × 12)

Total interest paid is calculated by subtracting the original loan amount from the total repayment amount.

Worked Example

Let's calculate a $200,000 loan with a 4.5% annual interest rate over 30 years:

Monthly interest rate = 4.5% ÷ 12 = 0.375% or 0.00375
Number of payments = 30 × 12 = 360
Monthly payment = $200,000 × [0.00375(1 + 0.00375)³⁶⁰] / [(1 + 0.00375)³⁶⁰ - 1] ≈ $1,125.46
Total repayment = $1,125.46 × 360 ≈ $405,164.40
Total interest = $405,164.40 - $200,000 ≈ $205,164.40

This example shows that a $200,000 loan at 4.5% over 30 years would result in approximately $1,125 monthly payments and $205,164 in total interest.

Frequently Asked Questions

What is the difference between fixed and variable rate loans?

Fixed rate loans have a constant interest rate throughout the loan term, while variable rate loans have an interest rate that can change based on market conditions. Fixed rate loans offer more predictable payments but may have higher initial rates, while variable rate loans may offer lower initial rates but can lead to higher payments if rates increase.

How does loan term affect monthly payments?

A longer loan term means lower monthly payments but more total interest paid. A shorter loan term means higher monthly payments but less total interest paid. Choose a term that fits your budget and financial goals.

What is the difference between APR and interest rate?

APR (Annual Percentage Rate) includes all fees and costs associated with borrowing, while the interest rate is the cost of borrowing without additional fees. APR is always higher than the interest rate and provides a more accurate picture of the total cost of borrowing.
