How Our Mortgage Calculator Works.

To use our online mortgage payment calculator, you’ll need to provide some preliminary details about the home you want to purchase and your loan details. It’s okay to use educated guesses when inputting your information into the calculator; you can adjust the numbers as you go. 


Here’s a breakdown of each mortgage calculator component:


  • Home Value: The selling price of the home
  • Down Payment: The amount the buyer has saved & is willing to invest in the property upfront. The average down payment is around 10%, though the benchmark is 20% to relax PMI requirements.
  • Loan Amount: Typically the home value less the down payment
  • Interest Rate: The annual percentage rate (APR) charged on the loan
  • Loan Term: The amortization period of the loan in years - typically 30 for most US residential loans
  • Property Tax: Annual property tax payment
  • PMI: Property mortgage insurance as a percent (typically between 0.5% and 1.3%, if less than 20% down payment is used).
  • Home Insurance: Annual cost of a homeowners insurance policy
  • Monthly HOA: Monthly dues for being part of a homeowners association.


How To Calculate a Mortgage Payment.

When figuring out how much house you can afford, you must first understand the different costs that go into a mortgage payment. These include: 


  • Principal and interest (P&I): The principal is the total amount you will borrow, whereas interest is an additional fee you pay to borrow the money. 
  • Property taxes: Homeowners need to pay an annual tax that’s determined by a government entity. The amount you’ll pay is based on factors like the current fair market value of your home. Your lender will hold this amount in an escrow amount and pays them when taxes are due. 
  • Mortgage insurance: In many cases, borrowers will need to pay private mortgage insurance (PMI) if their down payment is less than 20% for a conventional loan. PMI protects the lender if the loan isn’t repaid. 
  • Homeowners insurance: Your lender may also collect this amount monthly and pay the entire bill when it’s due. In some instances, you may be able to pay this bill directly to your insurance provider. Most lenders require some form of policy that will cover damage and losses from things such as fire, natural disasters, vandalism, and theft.


Our calculator uses the following formula to calculate a mortgage payment: 


M = P [ i÷12(1 + i÷12)^n ] / [ (1 + i÷12)^n – 1] 


Where: 

  • M = monthly mortgage payment 
  • P = the principal amount 
  • i = interest rate = number of monthly interest payments over the loan’s lifetime. 


Calculating your monthly mortgage payment can help you determine how much house you can afford. Once you see your estimated monthly payment, you can decide whether you need a bigger down payment or a longer loan term, or consider a different home type that’s more affordable.
