1. What is a Mortgage Rates Calculator?

Definition: This calculator estimates your monthly mortgage payment based on the loan amount, interest rate, and loan term.

Purpose: It helps homebuyers and homeowners understand their potential mortgage payments and compare different loan scenarios.

2. How Does the Calculator Work?

The calculator uses the standard mortgage formula:

Where:

• \( M \) — Monthly payment (USD)
• \( P \) — Loan principal (USD)
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• \( n \) — Number of payments (loan term in years × 12)

Explanation: The formula calculates the fixed monthly payment required to fully amortize (pay off) the loan over its term.

3. Importance of Mortgage Calculation

Details: Understanding your mortgage payment helps with budgeting, loan comparison, and determining how much house you can afford.

4. Using the Calculator

Tips: Enter the loan amount, current interest rate (check today's rates), and loan term (typically 15 or 30 years). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's included in a mortgage payment?
A: This calculates principal and interest only. Your actual payment may include taxes, insurance, and PMI if applicable.

Q2: How often do mortgage rates change?
A: Rates can change daily based on market conditions. Check with lenders for today's rates.

Q3: What's the difference between 15-year and 30-year mortgages?
A: 15-year loans have higher payments but lower rates and total interest. 30-year loans have lower payments but cost more overall.

Q4: How does a larger down payment affect my payment?
A: A larger down payment reduces your principal (P), resulting in a lower monthly payment.

Q5: Can I calculate payments for adjustable-rate mortgages?
A: This calculator is for fixed-rate mortgages only. ARM payments can change after the initial fixed period.
