Calculation Steps
- Enter the Loan Amount ($675,000).
- Enter the Annual Interest Rate (6.5%).
- Enter the Loan Term in Years (30).
$675,000 Mortgage Calculator Formula
Where:
- M = Monthly Payment (Principal and Interest)
- P = Principal Loan Amount
- r = Monthly Interest Rate (Annual Rate / 12 / 100)
- n = Total Number of Payments (Loan Term in Years × 12)
Variables
The calculation relies on three primary variables, corresponding to the inputs above:
- Principal (P): The initial amount of money borrowed, typically the purchase price minus the down payment. In this case, we are focusing on a principal of $675,000.
- Annual Interest Rate (R): The yearly cost of the loan, expressed as a percentage. This is converted to a monthly rate for the formula.
- Loan Term (T): The total duration (in years) over which you agree to repay the loan.

What is the $675,000 Mortgage Calculator?
The $675,000 mortgage calculator is a specialized financial tool designed to estimate the periodic payment required to fully pay off a fixed-rate loan of $675,000 over a specified period. It solves for the monthly payment amount, ensuring that by the final payment, both the principal loan amount and all accrued interest are fully retired.
This calculator uses the standard amortization formula, which accounts for the compound interest applied monthly. Early payments are heavily weighted towards interest, while later payments prioritize the reduction of the principal balance. This tool is essential for budgeting and understanding the long-term cost of borrowing.
How to Calculate Your Mortgage Payment (Example)
Let’s use an example with $675,000 Principal, 6.5% Rate, and a 30-Year Term:
- Determine Monthly Rate (r): Convert the annual rate to decimal and divide by 12. ($0.065 / 12 \approx 0.005417$)
- Determine Total Payments (n): Multiply the term in years by 12. ($30 \times 12 = 360$)
- Apply Formula Components: Calculate the monthly interest factor: $(1 + r)^n = (1.005417)^{360} \approx 6.9405$.
- Calculate Monthly Payment (M): Substitute all values into the formula and solve for M. ($675,000 \times \frac{0.005417 \times 6.9405}{6.9405 – 1}$)
Frequently Asked Questions (FAQ)
1. Does this calculator include property taxes and insurance (PITI)?No. This calculator exclusively calculates the Principal and Interest (P&I) portion of your payment using the standard amortization formula. Taxes, insurance, and HOA fees must be added separately to get your total monthly housing cost.
2. How does the interest rate affect my total payment?The interest rate is the most significant factor impacting your total payment and the amount of interest paid over the life of the loan. Even a small increase of 0.5% can result in tens of thousands of dollars more in interest over a 30-year term.
3. Why is the monthly payment so high in the beginning?Mortgages are structured so that a larger portion of your early monthly payments goes towards paying off the accumulated interest, while a smaller portion reduces the principal. This ratio gradually shifts over the loan term, with more of the payment going to principal later on.
4. What is the difference between Loan Term and Amortization Period?For a fixed-rate mortgage, they are often the same (e.g., 30 years). The Loan Term refers to the duration of the lending agreement, while the Amortization Period is the time required to pay the loan down to zero at the specified payment schedule.
