Mortgage Calculator USA

Use our free Mortgage Calculator USA to estimate your monthly mortgage payment based on your home price, down payment, loan term, interest rate, property taxes, homeowners insurance, mortgage insurance, and other housing costs.

A mortgage payment is more than just principal and interest. Depending on the loan and property, your total monthly housing payment may also include property taxes, homeowners insurance, mortgage insurance, and other costs.

How Does a Mortgage Calculator Work?

A mortgage calculator uses the loan amount, interest rate, and loan term to estimate the principal-and-interest portion of your monthly payment.

For a standard fixed-rate mortgage, the monthly principal-and-interest payment is determined by a mathematical formula based on the amount borrowed, interest rate, and repayment period.

The basic formula is:

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

This formula calculates principal and interest. Your actual total monthly housing cost may be higher when taxes, insurance, mortgage insurance, or other applicable costs are included.

What Is Included in a Monthly Mortgage Payment?

Your total mortgage-related payment can contain several components.

Principal

Principal is the amount you borrowed to purchase the home. As you make payments, the principal portion reduces your remaining loan balance.

Interest

Interest is the cost charged by the lender for borrowing the money.

With a typical fixed-rate mortgage, the total principal-and-interest payment remains generally consistent, but the amount going toward principal and interest changes over time. Early payments generally contain more interest because the outstanding balance is higher.

Property Taxes

Property taxes are charged by state and local governments and are a cost of owning the property.

If taxes are collected through an escrow account, part of your monthly payment may be set aside for future tax bills. Property taxes can change over time.

Homeowners Insurance

Homeowners insurance protects the property against covered risks. When insurance is paid through escrow, the monthly mortgage payment can include an amount set aside for the insurance bill.

Mortgage Insurance

Mortgage insurance may apply depending on the loan type and down payment.

For conventional mortgages, private mortgage insurance (PMI) is commonly associated with smaller down payments. FHA and USDA loans have their own mortgage-insurance requirements and costs.

HOA Fees

If the property belongs to a homeowners association, you may have an additional HOA fee. This fee is often separate from the mortgage payment itself, so it is useful to consider it when estimating your total monthly housing expense.

Mortgage Payment Example

Suppose you purchase a home for $400,000 and make a $80,000 down payment.

Your estimated loan amount would be:

$400,000 − $80,000 = $320,000

If the mortgage has a fixed interest rate and a 30-year term, the calculator can estimate the monthly principal-and-interest payment.

Your total monthly housing cost could then be higher after adding applicable property taxes, homeowners insurance, mortgage insurance, and HOA fees.

This is why comparing only the principal-and-interest payment can give an incomplete picture of your monthly housing cost. The CFPB recommends considering the total monthly payment, including applicable taxes, insurance, mortgage insurance, and escrow amounts.

How Much House Can I Afford?

A mortgage calculator can estimate payments, but the amount a lender is willing to lend is not necessarily the same as the amount you can comfortably afford.

When evaluating a home purchase, consider your income, existing debts, regular expenses, savings goals, emergency savings, taxes, insurance, maintenance, and other household costs.

The CFPB specifically notes that the amount you qualify to borrow can differ from what fits comfortably within your overall budget.

How Does a Down Payment Affect a Mortgage?

A larger down payment generally means you borrow less money.

For example:

$400,000 home

$40,000 down payment → $360,000 loan

$80,000 down payment → $320,000 loan

$120,000 down payment → $280,000 loan

A smaller loan balance generally means less principal to repay and can reduce the principal-and-interest payment, assuming the other loan terms remain the same.

A larger down payment can also affect mortgage insurance requirements depending on the loan type.

15-Year vs. 30-Year Mortgage

The loan term affects both your monthly payment and the total interest paid over time.

15-year mortgage

A shorter term generally means:

• Higher monthly principal-and-interest payment

• Faster repayment of principal

• Less time paying interest

30-year mortgage

A longer term generally means:

• Lower monthly principal-and-interest payment

• Longer repayment period

• More interest paid over the full term if the loan is kept until maturity

Use the calculator to compare different loan amounts, interest rates, and terms rather than looking only at the monthly payment.

What Is Mortgage Amortization?

Mortgage amortization is the process of gradually paying down the loan balance through scheduled payments.

With a typical fixed-rate mortgage, the payment is calculated so the loan is paid off at the end of the agreed term if the required payments are made as scheduled. Over time, the amount of each payment going toward principal increases while the interest portion decreases.

An amortization schedule can show:

• -Beginning loan balance
• -Monthly payment
• -Principal paid
• -Interest paid
• -Remaining balance
• -Total interest
  
  

Mortgage Interest Rate vs. APR

The mortgage interest rate and APR are related but they are not the same thing.

The interest rate is used to calculate the interest charged on the mortgage.

APR, or annual percentage rate, is a broader measure that can reflect the interest rate plus certain loan costs and fees.

When comparing mortgage offers, look at the rate, APR, upfront costs, monthly payment, and other loan terms rather than relying on a single number. The CFPB recommends reviewing the Loan Estimate when comparing mortgage offers.

What Are Mortgage Closing Costs?

Buying a home can involve costs beyond the down payment and monthly mortgage payment.

Examples can include:

-Lender charges
-Origination fees
-Discount points
-Appraisal costs
-Title-related costs
-Government fees
-Prepaid interest
-Initial escrow deposits
-Homeowners insurance
-Other transaction costs

• The exact costs vary by transaction and loan.
  
  

Frequently Asked Questions

What is a mortgage calculator?

A mortgage calculator is an online tool that estimates mortgage payments using information such as loan amount, interest rate, and loan term. More detailed calculators can also estimate taxes, insurance, mortgage insurance, and other housing costs.

How is a monthly mortgage payment calculated?

For a typical fixed-rate mortgage, the principal-and-interest payment is calculated using the loan amount, interest rate, and number of payments. The total monthly payment may also include applicable taxes, homeowners insurance, mortgage insurance, and other costs.

Does a mortgage payment include property taxes?

It can. Property taxes are often collected through an escrow account and included in the monthly amount paid to the mortgage servicer, but the exact arrangement depends on the loan and lender.

Does a mortgage payment include homeowners insurance?

It can. Homeowners insurance is often collected through escrow, but the exact payment arrangement depends on the mortgage and lender.

What is PMI?

PMI (private mortgage insurance) associated with certain conventional mortgages. Mortgage insurance can also apply to government-backed loans under their specific program rules. It increases the cost of borrowing and may be included in the overall monthly payment.

Is a 30-year mortgage cheaper than a 15-year mortgage?

A 30-year mortgage generally spreads repayment over a longer period, which can reduce the required monthly principal-and-interest payment. However, keeping a mortgage for the full longer term generally results in more interest paid than a comparable shorter-term loan.

Can I use a mortgage calculator to determine how much I can afford?

A calculator can help estimate payments, but it cannot determine your personal affordability by itself. Consider your income, debts, expenses, savings, taxes, insurance, maintenance, and other financial obligations before deciding what payment fits your budget.

How accurate is a mortgage calculator?

A mortgage calculator provides an estimate based on the information entered. Your actual mortgage payment and borrowing costs depend on the specific loan, lender, property, taxes, insurance, fees, and other terms.
