fairway mortgage calculator Formula
Monthly Payment (M) Calculation:
M = P [ i(1 + i)ⁿ / ((1 + i)ⁿ - 1) ]
Where:
P = Loan Principal (Amount Borrowed)i = Monthly Interest Rate (Annual Rate / 1200)n = Total Number of Payments (Loan Term in Years * 12)

Variables Explained
- Loan Amount (Principal): The total amount of money you are borrowing from the lender for your home purchase or refinance.
- Annual Interest Rate: The yearly rate charged for borrowing the funds, expressed as a percentage. This rate is compounded monthly for payment calculations.
- Loan Term (Years): The total length of time over which you agree to repay the loan, typically 15 or 30 years.
- Monthly Payment: The fixed amount paid every month, consisting of both principal repayment and interest charges.

What is a Fairway Mortgage Calculator?
The fairway mortgage calculator is an essential financial tool used by prospective and current homeowners to determine the financial implications of a mortgage loan. At its core, it uses the standard amortization formula to calculate the fixed monthly payment required to pay off the principal and interest over the life of the loan. This calculation is crucial for budgeting and understanding the long-term cost of borrowing.
While the name “fairway” may be associated with a specific lending institution, the underlying mechanics of this calculator follow universally accepted real estate finance principles. It allows users to manipulate key variables—Loan Amount, Interest Rate, and Term—to run various scenarios, helping them find a monthly payment that comfortably fits within their budget.
How to Calculate Your Mortgage Payment (Example)
- Gather Inputs: Assume a Loan Principal ($P$) of $250,000, an Annual Interest Rate ($r$) of 4.5%, and a Loan Term ($t$) of 30 years.
- Calculate Monthly Interest Rate (i): Divide the annual rate by 1,200 (4.5 / 1200), yielding $i = 0.00375$.
- Calculate Total Payments (n): Multiply the term by 12 (30 years * 12 months), yielding $n = 360$ payments.
- Apply the Formula: Substitute the values into the monthly payment formula: $M = 250,000 \times [ 0.00375(1 + 0.00375)^{360} / ((1 + 0.00375)^{360} – 1) ]$.
- Determine Monthly Payment: The resulting fixed monthly payment ($M$) for Principal and Interest is approximately $1,266.71.
Frequently Asked Questions (FAQ)
Is the monthly payment shown inclusive of taxes and insurance?
No. The monthly payment calculated only includes the Principal and Interest (P&I) portion of your loan. It does not include Property Taxes, Homeowner’s Insurance, or Mortgage Insurance (PMI/MIP), often referred to as escrow payments (T&I).
What is the difference between Loan Term and Amortization Period?
In the US, these terms are often used interchangeably. Both typically refer to the full duration (e.g., 30 years) over which the loan is paid off. In some countries, the term is the duration of the interest rate contract, which is shorter than the full amortization period.
How can I save money on my mortgage?
You can save money by making extra principal payments, choosing a shorter loan term (like 15 years), or securing a lower interest rate through refinancing. Any extra money applied to the principal reduces the interest base immediately.
Why is the calculated amount different from my bank’s estimate?
Differences usually arise from compounding frequency (some lenders use semi-annual), inclusion of mortgage insurance (PMI), or fees. Always confirm final payment amounts with your lender.
