Usaa Mortgage Calculator with Taxes and Insurance

This USAA mortgage calculator helps you estimate your monthly payments including property taxes and homeowners insurance. By including these costs, you'll get a more accurate picture of your total monthly mortgage obligation.

How the USAA Mortgage Calculator Works

The USAA mortgage calculator estimates your monthly payments by considering three key components: the principal loan amount, the interest rate, and the loan term. It then adds property taxes and homeowners insurance to give you a complete picture of your monthly mortgage costs.

Note: This calculator provides an estimate. Actual payments may vary based on your specific loan terms and local tax rates.

Key Components of Your Mortgage Payment

Your monthly mortgage payment consists of several parts:

Principal: The portion of your payment that reduces the loan balance
Interest: The cost of borrowing the money
Property Taxes: Annual property taxes divided by 12
Homeowners Insurance: Annual insurance premium divided by 12

Why Include Taxes and Insurance

Many mortgage lenders require borrowers to pay property taxes and homeowners insurance as part of their monthly mortgage payment. Including these costs in your calculation gives you a more accurate understanding of your total monthly obligation.

Formula Used

The calculator uses the following formula to estimate your monthly mortgage payment:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1) + (Property Taxes / 12) + (Homeowners Insurance / 12)

Where:

P = Principal loan amount
r = Monthly interest rate (Annual Rate / 12)
n = Number of payments (Loan Term in years × 12)

This formula calculates the principal and interest portion of your payment using the standard mortgage payment formula, then adds the monthly property taxes and insurance.

Worked Example

Let's walk through an example to see how the calculator works:

Example Calculation

Suppose you're taking out a $300,000 mortgage with a 4.5% interest rate over 30 years. Your property taxes are $12,000 annually and your homeowners insurance is $1,500 annually.

Calculate the monthly interest rate: 4.5% ÷ 12 = 0.375% or 0.00375
Calculate the number of payments: 30 years × 12 = 360 payments
Calculate the principal and interest portion:

P = $300,000, r = 0.00375, n = 360

Monthly Payment = $300,000 × (0.00375(1 + 0.00375)^360) / ((1 + 0.00375)^360 - 1)

≈ $300,000 × 0.00504 ≈ $1,512.00
Add property taxes: $12,000 ÷ 12 = $1,000
Add homeowners insurance: $1,500 ÷ 12 = $125
Total monthly payment: $1,512 + $1,000 + $125 = $2,637

This example shows that including taxes and insurance increases your total monthly payment by $2,125 compared to just the principal and interest portion.
