Mortgage Calculator
Estimate your monthly mortgage payment, total interest, and loan payoff schedule.
Taxes, Insurance & PMI
Buying a home is a major financial decision, and knowing your possible monthly payment can make the process easier. Our Mortgage Calculator helps you estimate how much you may pay each month based on your home price, down payment, interest rate, loan term, taxes, insurance, and other costs.
Enter your numbers into the calculator above to get an estimate. You can change the inputs to compare different home prices, down payments, interest rates, and loan terms.
This calculator is designed to help you understand the numbers before you speak with a lender or make a home-buying decision. The result is an estimate, not a loan offer or guarantee.
What Is a Mortgage Calculator?
A mortgage calculator is an online tool that estimates the cost of borrowing money to buy a home.
The basic calculation uses the loan amount, interest rate, and loan term to estimate your principal and interest payment. A more complete mortgage calculator can also include property taxes, homeowners insurance, private mortgage insurance (PMI), and other housing costs.
For example, if you are planning to buy a $300,000 home, you can enter the home price, down payment, interest rate, and loan term. The calculator can then show an estimated monthly payment and the total interest you could pay over the life of the loan.
This makes it easier to compare different mortgage options before choosing a loan.
How Does a Mortgage Calculator Work?
A mortgage calculator normally starts with five important numbers:
| Input | What It Means |
|---|---|
| Home Price | The purchase price of the property |
| Down Payment | The amount you pay upfront |
| Loan Amount | The amount you borrow |
| Interest Rate | The annual cost of borrowing |
| Loan Term | How long you have to repay the loan |
The calculator uses these numbers to estimate your monthly principal and interest payment.
Depending on the calculator, you may also be able to add property taxes, homeowners insurance, HOA fees, and PMI. Including these costs can give you a more realistic estimate of your total monthly housing expense. Bankrate’s mortgage calculator, for example, includes principal, interest, taxes, insurance, HOA fees and PMI in its broader payment estimate.
Mortgage Payment Formula
For a fixed-rate mortgage, the principal and interest payment can be calculated using a standard amortization formula:
M = P × [r(1 + r)ⁿ / ((1 + r)ⁿ − 1)]
Where:
- M = monthly principal and interest payment
- P = loan principal
- r = monthly interest rate
- n = total number of monthly payments
The annual interest rate is converted into a monthly rate before the calculation is performed.
You normally do not need to calculate this formula yourself. The mortgage calculator performs the calculation automatically.
What Is Included in a Monthly Mortgage Payment?
Your total monthly housing payment can contain several different costs.
Principal
Principal is the amount of money you borrowed to purchase the home.
When you make a mortgage payment, part of your payment normally goes toward reducing this balance.
Interest
Interest is the cost of borrowing money from the lender.
At the beginning of a typical fixed-rate mortgage, a larger portion of the payment goes toward interest. As the loan balance decreases, more of each payment goes toward principal.
Property Taxes
Property taxes are paid to the local government based on the property and local tax rules.
The actual amount can vary significantly by location and property value, so the amount entered into a calculator should be treated as an estimate unless you have the exact tax figure.
Homeowners Insurance
Homeowners insurance helps protect the property against covered risks.
The cost depends on factors such as the property, location, coverage, deductible, and insurance provider.
Private Mortgage Insurance (PMI)
PMI may apply to certain conventional mortgages when the down payment is below a lender’s required threshold.
The exact requirement and cost depend on the loan and borrower. For this reason, you should use your lender’s actual PMI estimate when available.
HOA Fees
Some homes, especially condos and properties in planned communities, have homeowners association fees.
These fees are usually separate from principal and interest but can be important when calculating the true monthly cost of owning a home.
Example Mortgage Calculation
Suppose you want to buy a home for $300,000.
For a simple example, assume:
| Example | Amount |
|---|---|
| Home Price | $300,000 |
| Down Payment | $60,000 |
| Loan Amount | $240,000 |
| Interest Rate | 6.5% |
| Loan Term | 30 years |
| Number of Payments | 360 |
At these assumptions, the estimated principal and interest payment is about $1,517 per month.
This figure does not automatically represent your complete housing payment because property taxes, homeowners insurance, PMI, HOA fees, and other costs may apply.
That is why it is important to look at the full payment rather than only the principal and interest amount.
How to Use Our Mortgage Calculator
Using the calculator is simple.
Step 1: Enter the Home Price
Enter the expected purchase price of the home.
For example, if the house costs $350,000, enter 350000.
Step 2: Add Your Down Payment
Enter the amount you plan to pay upfront.
A larger down payment generally means a smaller loan balance.
Step 3: Enter the Interest Rate
Enter the mortgage interest rate you want to estimate.
If you already received a rate from a lender, use that rate for a more useful estimate.
Step 4: Select the Loan Term
Common mortgage terms include:
- 30 years
- 20 years
- 15 years
- 10 years
A longer term usually produces a lower required monthly principal-and-interest payment, while a shorter term generally increases the monthly payment but can reduce total interest.
Step 5: Add Additional Costs
If your calculator includes these fields, enter estimates for:
- Property taxes
- Homeowners insurance
- PMI
- HOA fees
Adding these costs can make the monthly estimate more useful for budgeting.
Step 6: Review Your Results
Look at the estimated:
- Monthly payment
- Principal
- Interest
- Taxes
- Insurance
- PMI
- Total loan cost
- Total interest
Then change one input at a time to see how the result changes.
How a Down Payment Changes Your Mortgage
Your down payment has a direct effect on how much you need to borrow.
For example:
| Home Price | Down Payment | Approx. Loan Amount |
|---|---|---|
| $300,000 | $30,000 | $270,000 |
| $300,000 | $60,000 | $240,000 |
| $300,000 | $90,000 | $210,000 |
| $300,000 | $120,000 | $180,000 |
A larger down payment means a smaller starting loan balance.
However, putting more money down is not always the only consideration. Buyers should also think about closing costs, emergency savings, moving expenses, repairs, and other financial needs.
How Interest Rate Affects Your Mortgage
The interest rate can make a large difference in the total cost of a mortgage.
Consider the same $240,000 loan over 30 years:
| Interest Rate | Approx. Monthly Principal & Interest |
|---|---|
| 5.5% | $1,363 |
| 6.0% | $1,439 |
| 6.5% | $1,517 |
| 7.0% | $1,597 |
| 7.5% | $1,678 |
These are illustrative calculations for principal and interest only. Taxes, insurance, PMI and other costs are not included.
This example shows why even a relatively small change in the interest rate can affect your monthly budget.
How Loan Term Changes Your Payment
The loan term determines how long you have to repay the mortgage.
For example, a 15-year mortgage normally requires larger monthly principal-and-interest payments than a 30-year mortgage for the same loan amount and rate.
However, paying the loan over fewer years can significantly reduce the total interest paid.
| Loan Term | General Effect |
|---|---|
| 30 years | Lower monthly payment, longer repayment |
| 20 years | Higher payment, shorter repayment |
| 15 years | Higher payment, potentially much less interest |
| 10 years | Much higher payment, fastest repayment |
The best term depends on your budget, financial goals, interest rate, and loan options.
Mortgage Calculator With Taxes and Insurance
Looking only at principal and interest can make a home appear less expensive than it really is.
Your total monthly housing cost may also include property taxes and homeowners insurance.
For example:
| Monthly Cost | Example |
|---|---|
| Principal & Interest | $1,517 |
| Property Taxes | $300 |
| Home Insurance | $125 |
| PMI | $100 |
| HOA | $75 |
| Estimated Total | $2,117 |
These numbers are only an example. Your actual costs can be very different depending on the home, location, loan type, insurance policy, taxes, and lender.
This is why a calculator that lets you include additional costs can be more useful for budgeting.
What Is Amortization?
Amortization is the process of paying a loan over time through scheduled payments.
With a typical fixed-rate mortgage, the total principal-and-interest payment may remain the same each month, but the amount going toward principal and interest changes.
Early in the loan, more of the payment can go toward interest because the outstanding balance is larger.
As you pay down the loan, the balance decreases and more of the payment goes toward principal.
An amortization schedule can show this change month by month.
Mortgage Amortization Example
Here is a simplified example for a $240,000 mortgage at 6.5% for 30 years:
| Period | What Happens |
|---|---|
| Early payments | More payment goes toward interest |
| Middle of loan | Principal portion gradually increases |
| Later payments | More payment goes toward principal |
| End of loan | Remaining principal reaches zero |
The exact numbers depend on the loan terms and payment schedule.
How Much House Can I Afford?
A mortgage calculator can estimate a payment, but it does not automatically determine whether a home is affordable for you.
Before buying a home, consider your complete monthly budget.
Include:
- Mortgage payment
- Property taxes
- Home insurance
- PMI
- HOA fees
- Utilities
- Maintenance
- Other debts
- Emergency savings
- Everyday living costs
Your lender may also review your income, debts, credit profile, assets, and other financial information when evaluating a mortgage application.
The calculator should therefore be used as a planning tool, not as a final affordability decision.
Mortgage Calculator vs. Loan Estimate
These are not the same thing.
A mortgage calculator gives you an estimate based on the information you enter.
A lender’s loan estimate is based on a specific mortgage application and provides more detailed information about the proposed loan and costs.
Use the calculator for early planning and comparison. When you are seriously considering a mortgage, review the official documents provided by your lender.
How to Lower Your Monthly Mortgage Payment
There are several factors that can affect your monthly payment.
Increase Your Down Payment
A larger down payment can reduce the amount you borrow.
Compare Interest Rates
Even small differences in interest rates can affect the monthly payment and total interest.
Consider Different Loan Terms
A longer term can reduce the required monthly payment, while a shorter term can reduce the time you remain in debt.
Compare Property Prices
A lower home price naturally reduces the amount you need to finance.
Review Additional Costs
Taxes, insurance, PMI and HOA fees can add hundreds of dollars to your monthly housing cost.
Do not focus only on the advertised mortgage rate. Look at the complete cost of the loan.

Mortgage Calculator Tips
For a better estimate, try these tips:
- Use a realistic home price.
Do not calculate only the maximum amount a lender might approve. - Use the interest rate you expect to receive.
If you have a lender quote, use that rate. - Include taxes and insurance.
These costs can make a large difference to your monthly housing budget. - Test several down payments.
Compare the payment with 5%, 10%, 20%, and other possible down payments when relevant. - Compare loan terms.
Try 15-year and 30-year options to understand the trade-off between monthly payment and total interest. - Remember that estimates are not guarantees.
Your final mortgage costs depend on the actual loan, lender, property, location, and borrower information.
Common Mortgage Calculator Mistakes
Looking Only at the Monthly Payment
A low monthly payment does not always mean a cheaper mortgage.
You should also look at the total interest and total cost over the life of the loan.
Forgetting Property Taxes
Taxes can be a significant part of the total monthly housing expense.
Ignoring Insurance
Homeowners insurance should be included when estimating the real cost of owning a property.
Using an Unrealistic Interest Rate
A calculator result is only as useful as the information entered into it.
Spending Every Dollar on the Down Payment
A home purchase can involve closing costs, moving expenses, repairs, and unexpected expenses. Make sure your overall budget leaves room for these costs.
Frequently Asked Questions
What is a mortgage calculator?
A mortgage calculator is an online tool that estimates your monthly mortgage payment based on information such as the home price, down payment, interest rate, and loan term.
How accurate is a mortgage calculator?
A mortgage calculator provides an estimate. Your actual payment may be different because of lender terms, taxes, insurance, PMI, fees, interest rates, and other costs.
Does a mortgage calculator include taxes and insurance?
Some calculators include property taxes and homeowners insurance. If your calculator has these input fields, adding them can give you a more complete estimate of your monthly housing cost.
Does a mortgage calculator include PMI?
A calculator may include PMI if there is a PMI field. PMI requirements and costs depend on the loan type, down payment, lender, and borrower information.
What is the difference between a mortgage calculator and a home loan calculator?
In many cases, the terms are used for the same type of tool. Both can estimate the cost of borrowing money to purchase a home.
Is a 15-year mortgage better than a 30-year mortgage?
Neither is automatically better for everyone. A 15-year mortgage can mean higher monthly payments but may reduce total interest. A 30-year mortgage usually provides a lower required monthly payment but keeps the loan outstanding for longer.
Does a larger down payment lower my monthly payment?
Generally, yes. A larger down payment reduces the amount you need to borrow, which can reduce the principal-and-interest portion of your monthly payment.
Can I use this calculator to decide how much house I can afford?
You can use it as a starting point for budgeting, but it should not be the only factor. Consider your income, debts, savings, taxes, insurance, maintenance and other financial responsibilities.
Why is my mortgage payment different from the calculator result?
Your actual payment may include costs or loan terms that were not included in the calculator. Property taxes, insurance, PMI, HOA fees, lender fees, rate changes and other factors can affect the final amount.
Can I use a mortgage calculator before applying for a loan?
Yes. It can be useful before applying because you can compare different home prices, down payments, interest rates and loan terms before talking with a lender.
Final Thoughts
A mortgage is a long-term financial commitment, so understanding the numbers before buying a home is important. Our Mortgage Calculator gives you a simple way to estimate your monthly payment and explore how different loan choices can affect your budget.
Try different home prices, down payments, interest rates and loan terms. If available, include taxes, insurance, PMI and HOA costs for a more complete estimate.
