A mortgage calculator is a helpful tool that estimates your monthly mortgage payment based on factors such as the home's purchase price, down payment, loan amount, interest rate, and loan term.
Whether you're just beginning your home search or comparing financing options, using a mortgage calculator can help you understand what a home may cost each month and determine a budget that works for you.
Keep in mind: Mortgage calculators provide estimates only. Your actual monthly payment and loan terms will be determined by your lender.
What Can a Mortgage Calculator Estimate?
A mortgage calculator can help estimate:
Monthly principal and interest payments
Estimated loan amount
Down payment amount
Loan payoff term
Estimated interest paid over the life of the loan
Estimated monthly housing costs
Some calculators may also estimate:
Property taxes
Homeowners insurance
Mortgage insurance (PMI or MIP)
HOA dues
Total monthly payment (often called PITI: Principal, Interest, Taxes, and Insurance)
Information You'll Need
To receive the most accurate estimate, you'll typically enter:
Home purchase price
Down payment amount or percentage
Interest rate
Loan term (such as 15 or 30 years)
Estimated property taxes
Homeowners insurance premium
HOA fees (if applicable)
If you're unsure about any of these figures, you can use estimated values and update them later as you gather more information.
How to Use a Mortgage Calculator
Enter the estimated purchase price of the home.
Add your expected down payment.
Select your loan term.
Enter an estimated interest rate.
Include estimated taxes, insurance, and HOA fees if available.
Review your estimated monthly payment.
Adjust the numbers to compare different buying scenarios.
Experimenting with different down payment amounts, loan terms, and home prices can help you understand how each factor affects your monthly payment.
Ways to Compare Scenarios
Mortgage calculators are useful for comparing different financing options, such as:
Compare Home Prices
See how increasing or decreasing your purchase price affects your monthly payment.
Compare Down Payments
Learn how a larger down payment may reduce your monthly payment and total interest costs.
Compare Loan Terms
Review the differences between:
15-year mortgage
20-year mortgage
30-year mortgage
Shorter loan terms often result in higher monthly payments, but lower total interest paid over time.
Compare Interest Rates
Even a small change in the interest rate can significantly impact your monthly payment and the total cost of your mortgage.
What Mortgage Calculators Don't Include
While mortgage calculators are valuable planning tools, they cannot account for every expense associated with homeownership.
Actual costs may vary due to:
Loan program requirements
Closing costs
Property inspections
Maintenance and repairs
Utility expenses
Changes in property taxes or insurance premiums
Lender-specific fees
For a complete picture of your financing costs, speak with a loan officer.
