What Details Are Included in a Mortgage Calculator Online?

When you are preparing to buy a home, you probably want to know how much your monthly mortgage payments will be. A mortgage calculator online can help you estimate the costs of buying a home so that you know what to expect.

Here are the details that a mortgage calculator can provide you.

Why A Mortgage Calculator Online Is Helpful

Some new homebuyers make the mistake of purchasing a house that exceeds their budgets. This costly error causes a lot of financial stress for homeowners and may eventually lead to a foreclosure if they cannot meet monthly payments.

While mortgage calculators only give you an estimate, approximate mortgage costs will give you a clearer idea of how much your home payments will be.

Down Payment Sizes

One key part of the home shopping process is the down payment. Everyone who has ever dipped their toes in the real estate market is aware that traditional down payments are 20% of a home’s total cost.

However, most buyers today put down less than 20% on their houses. First-time buyers in particular usually choose smaller down payment options, while repeat buyers typically make bigger down payments.

In 2021, the National Association of Realtors (NAR) reported a median down payment of 12% across the country.

With the help of an online mortgage calculator, you can input a home price, interest rate, mortgage term, and down payment size to find out approximately how much your total monthly payments would be. This helpful prediction can aid you in deciding what size down payment you will put on your home.

Expected Monthly Payments

When you finally own a home, you will have to pay monthly mortgage fees until you pay off your loan. Mortgage payments are not just small pieces of the total price of your home; additional fees are involved in each monthly payment. These fees include property tax and homeowners insurance.

Generally, the shorter your term, the higher each monthly payment will be. On the opposite end of things, a 30-year mortgage will include lower monthly payments.

A mortgage calculator can give you a good idea of what to expect from your mortgage payments. You can use information including your mortgage length, interest rate, loan amount, and estimated yearly insurance and taxes to find out how much your home might cost you each month.


Mortgage calculators aren’t just for recent home buyers. You can also use this online tool to help you see if refinancing your house is a prudent decision.

Refinancing can be a good decision for many homeowners who have been paying a mortgage for at least a year. Reasons to replace your existing mortgage with a new one include superior interest rates and reduced monthly payments.

While the benefits of refinancing are clear, it is a wise idea to get an estimate of how much a refinanced mortgage may cost. Choosing the wrong refinancing option could be risky if you make a large purchase, and depend on better mortgage rates to build up your home equity.

With a refinance calculator, you can input your current mortgage term, monthly payment, and interest rate along with refinancing details to find out how much money you might be able to save.


Do you have your eye on our dream home, but you are unsure if you can afford it? Affordability depends on many factors from the total price of a house to your yearly income and monthly debt payments.

An affordability calculator uses several key financial details to determine affordability for an adjustable-rate or fixed-rate mortgage. You can input expected fees including debt payments, annual insurance and tax fees, principal loan balance, home price, interest rate, and amortization length. With this information, you can get a good estimate of how much money you will need to pay your mortgage and everyday necessities each month and year.

If you want to find out how much to pay for a house or what size down payment you should decide on, an online calculator can help. It is important to make sure that the mortgage calculator you choose is from a reputable mortgage company.
