How to Use the Mortgage Calculator

Follow these simple steps to calculate your monthly mortgage payment and understand the total cost of your home loan.

Step-by-Step Guide

1
Enter Loan Amount

Input the total amount you plan to borrow for your mortgage

  • This is your home price minus your down payment
  • Example: $400,000 home - $80,000 down = $320,000 loan
  • Use the slider or type directly for precision

2
Set Interest Rate

Enter your annual interest rate as a percentage

  • Check current market rates or your pre-approval letter
  • Rates typically range from 6% to 8% in 2025
  • Even 0.25% difference significantly impacts total cost

3
Choose Loan Term

Select how many years you'll take to repay the loan

  • 30 years: Lower monthly payments, more total interest
  • 15 years: Higher monthly payments, less total interest
  • Custom terms available (10-40 years)
