When you’re thinking about buying a home, you need clear, helpful information to make the best financial choices for your individual situation.

Free and easy to use, the calculator can be one of the most important tools you’ll rely on during your search. Let’s take a closer look.

Key Points

•  Mortgage calculators can help you determine monthly and overall costs for different mortgages when you input factors like home price, down payment, loan term, and interest rate.

•  Lenders prefer your mortgage payments to be less than 28% of your gross monthly income.

•  Mortgage payments may include principal, interest, property taxes, homeowners insurance, and potentially private mortgage insurance (PMI), or homeowners association (HOA) fees.

•  Options that may help you reduce mortgage payments include dropping PMI once you reach 20% equity, appealing high property taxes, and refinancing to a lower rate, among others.

•  First-time homebuyers in Arizona may be able to access a variety of financial assistance programs offered through the state and local organizations.

Calculator Definitions

• Home price: This is the purchase price for the property that you and the seller agree on. As the final price, it will probably differ from both the initial listing price and the amount of your first offer.

• Down payment: This is the amount that you pay upfront for the property, often expressed as a percentage of the total purchase price. Most buyers put down between 3% and 20%. A down payment of 20% or more will let you avoid paying private mortgage insurance (PMI). Down payment assistance programs may be available to help you cover this cost.

• Loan term: This is the length of time you have to repay your home loan, usually 15 or 30 years. A shorter term means higher monthly payments but less interest charged over the life of the loan. A longer term can make monthly payments more manageable but cost more in the long run.

• Interest rate: This is the cost of borrowing money and is typically expressed as a percentage of the total loan amount. The rate a lender offers you will depend on market trends and your personal financial situation, among other factors.

• Annual property tax: Property tax is levied by local governments on land and buildings and is generally expressed as a percentage of a property’s assessed value. Find your property tax rate by searching online for the town, county, or ZIP code where the property is located and “effective property tax rate.”

• Monthly payment: The amount you’ll pay your lender each month includes both mortgage principal and interest. It may also cover estimated property taxes, homeowners insurance, and possibly any homeowners association (HOA) fees. If your down payment was less than 20% and you need to pay for private mortgage insurance (PMI), that’s generally also part of the monthly payment.

• Total interest paid: This figure is the cumulative amount of interest you’ll pay over the entire duration of the loan. That amount can be substantial, especially with longer loan terms. Opting for a larger down payment or a shorter loan term can reduce the total interest paid over time.

• Total loan cost: This is the entire amount you’ll pay during the life of the loan, including the principal amount you borrowed and all the interest accrued throughout the loan term. Factors like loan term length, interest rate, and down payment amount all play into the total loan cost.
