What is the Mortgage Calculator?
A mortgage calculator is an online tool that estimates how much you may pay each month for a home loan. By entering your home purchase price, down payment, mortgage interest rate, and loan term, you can quickly estimate the principal and interest portion of your monthly payment.
Our mortgage payment calculator can also account for common U.S. housing expenses such as property taxes, homeowners insurance, HOA fees, and private mortgage insurance (PMI). Including these costs can provide a more realistic estimate than calculating principal and interest alone.
For example, a buyer purchasing a $400,000 home with a 20% down payment would finance approximately $320,000 before other costs. The estimated payment then depends on the selected interest rate and mortgage term, such as a 15-year or 30-year fixed-rate loan.
You can use this monthly mortgage payment calculator to compare different home prices, down payments, interest rates, and loan terms before speaking with a lender. It can also help with household budgeting and understanding how changes in mortgage rates may affect monthly housing costs.
Results are estimates only. Actual mortgage payments can vary based on lender terms, credit profile, local property taxes, insurance premiums, closing costs, and other fees.

Formula & Calculations
M = P * [r(1+r)^n] / [(1+r)^n – 1]
Where:
- M = Monthly principal and interest payment
- P = Mortgage principal or loan amount
- r = Monthly interest rate
- n = Total number of monthly payments
To see how compounding works for savings and investments rather than an amortizing home loan, use our Compound Interest Calculator.
Estimated Total Monthly Mortgage Payment
Total Payment = Principal & Interest + Property Tax + Homeowners Insurance + HOA Fees + PMI
This makes the tool a mortgage calculator with taxes and insurance, rather than a basic principal-and-interest calculator.
How This Mortgage Calculator Works
Our home loan calculator first subtracts your down payment from the home purchase price to estimate your mortgage principal. It then applies the selected annual interest rate and loan term to calculate the estimated monthly principal and interest payment.
Annual property taxes and homeowners insurance are converted into monthly amounts and added to the payment estimate. Monthly HOA fees are included when entered.
If applicable, PMI may also be added when the down payment is below the calculator’s defined threshold. Actual PMI requirements and rates vary by lender, loan program, credit profile, and loan to value ratio.

Worked Example
Consider a $400,000 home with a 20% down payment of $80,000.
Estimated loan amount: $320,000
Mortgage term: 30 years
Interest rate: 6.5%
Number of payments: 360
At these assumptions, the estimated monthly principal and interest payment is approximately $2,023.
Property taxes, homeowners insurance, HOA fees, and PMI when applicable would then be added to estimate the total monthly housing payment.
Because mortgage rates and other housing costs change, always enter your own current figures for a more relevant estimate.

Core Assumptions
- Uses a fixed interest rate for the selected loan term.
- Payments are calculated using standard monthly amortization.
- Annual property tax and insurance amounts are divided across 12 months.
- Down payment is deducted from the home price to estimate the loan principal.
- HOA fees are treated as a monthly housing expense.
- PMI is an estimate and may not match a lender’s actual premium.
- Calculations are based on the information entered by the user.
System Limitations
- Does not provide mortgage pre-approval or lending decisions.
- Adjustable-rate mortgage changes may not be reflected.
- Closing costs and lender-specific fees may be excluded.
- Local transfer taxes and special assessments may not be included.
- Actual PMI rates vary by lender and borrower profile.
- Property tax and insurance costs vary by location.
- Results should not be treated as financial or lending advice.
What Costs Are Included in a Monthly Mortgage Payment?
A monthly mortgage payment may include more than repayment of the home loan itself. Depending on your mortgage and property, your housing payment can include:
Principal: The portion of your payment used to reduce the loan balance.
Interest: The amount charged by your lender for borrowing money.
Property Taxes: Local taxes assessed on the property, often collected through an escrow account.
Homeowners Insurance: Insurance that may protect the home against covered losses.
PMI: Private mortgage insurance may be required on some conventional mortgages when the buyer makes a smaller down payment.
HOA Fees: Some condominiums and planned communities charge separate homeowners association fees.
Using a mortgage calculator with taxes and insurance helps produce a more complete estimate of potential monthly housing costs.
Frequently Asked Questions About Mortgage Calculators
The monthly payment on a $300,000 mortgage depends on the interest rate, loan term, taxes, insurance, and other housing costs.
A monthly mortgage payment is calculated using the loan principal, interest rate, and repayment term. Property taxes, insurance, HOA fees, and PMI may then be added to estimate the total monthly housing payment
Yes. You can enter estimated annual property taxes and homeowners insurance to calculate a more complete monthly mortgage payment.
A larger down payment generally reduces the amount you need to borrow. A smaller loan principal typically results in a lower principal-and-interest payment, assuming other loan terms remain unchanged.
The calculator allows PMI to be included where applicable. Actual PMI requirements and rates vary based on loan type, down payment, credit profile, and lender policies.
A larger down payment generally reduces the amount you need to borrow. A smaller loan principal typically results in a lower principal-and-interest payment, assuming other loan terms remain unchanged.
A 15-year mortgage generally has higher monthly payments but repays the loan faster. A 30-year mortgage typically has lower monthly payments but spreads repayment over a longer period.
Lenders typically require PMI if your down payment is less than 20% of the home’s purchase price. It protects the lender not you in case you default on the loan.
HOA fees are generally separate from the mortgage loan itself, but they are an important monthly housing expense. This calculator lets you include HOA fees in your estimated total monthly cost.
A mortgage calculator can provide a useful estimate based on the values entered. Actual payments can differ because of lender fees, taxes, insurance premiums, PMI, escrow adjustments, and loan-specific terms.
