Formula Used
Monthly Payment Calculation
The monthly payment is calculated using the standard mortgage formula:
M = P [i(1 + i)^n] / [(1 + i)^n - 1]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (15 years × 12 months)
Property Tax Calculation
Annual property tax = Property Value × Tax Rate
Monthly property tax = Annual property tax / 12
Total monthly payment includes both the mortgage payment and property tax.
Worked Example
Let's calculate a $200,000 mortgage at 4.5% interest with a 1.2% property tax rate on a $250,000 property value.
- Monthly interest rate = 4.5% ÷ 12 = 0.375%
- Number of payments = 15 × 12 = 180
- Monthly mortgage payment = $200,000 [0.00375(1.00375)^180] / [(1.00375)^180 - 1] ≈ $1,285.42
- Annual property tax = $250,000 × 1.2% = $3,000
- Monthly property tax = $3,000 ÷ 12 = $250
- Total monthly payment = $1,285.42 + $250 = $1,535.42
Over 15 years, you would pay approximately $1,535.42 per month, with $225,000 going toward principal and $17,400 in total interest.
Interpreting Results
The calculator provides several key metrics to help you understand your mortgage:

- Exact loan terms from your lender
- Changes in interest rates
- Property tax assessments
- Additional fees or closing costs
Frequently Asked Questions
What is a 15-year mortgage?
A 15-year mortgage is a home loan that's repaid over 15 years instead of the more common 30-year term. It typically has a higher interest rate but lower monthly payments.
How does property tax affect my mortgage?
Property taxes are additional monthly costs that add to your total mortgage payment. The calculator shows how much your property taxes will be based on your property value and tax rate.
Is a 15-year mortgage right for me?
Consider a 15-year mortgage if you can afford higher monthly payments and want to pay off your loan faster. It's particularly suitable if you plan to sell or refinance before the 15 years are up.
What's the difference between interest rate and APR?
The interest rate is the cost of borrowing, while APR (Annual Percentage Rate) includes all fees and costs associated with the loan. APR is typically higher than the interest rate.
