Mortgage Payment Formula
The standard formula for calculating the monthly payment (M) of a fixed-rate loan is:
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]
Sources: Investopedia – Mortgage Formula, CFPB – Loan Options
Variables Explained
- M (Monthly Payment): The required monthly payment (principal and interest).
- P (Principal Loan Amount): The total amount borrowed for the home purchase.
- i (Monthly Interest Rate): The annual interest rate divided by 12 and then by 100 (e.g., 6% becomes 0.06/12).
- n (Number of Payments): The total number of monthly payments over the loan’s term (Years × 12).

What is the Navy Federal Mortgage Calculator?
The Navy Federal Mortgage Calculator is a tool designed to estimate the monthly principal and interest payments for a potential home loan. While Navy Federal Credit Union offers various mortgage products (Conventional, VA, Fixed-Rate), this standard calculation provides a crucial starting point for budgeting. It allows members, especially those who are active duty, veterans, or their families, to determine affordability based on their desired loan amount, the current annual interest rate, and the chosen repayment term (e.g., 15 or 30 years).
Understanding your monthly payment is key to financial planning. Remember that the amount calculated here only covers principal and interest (P&I). Your actual monthly payment often includes escrow for property taxes and homeowner’s insurance (PITI), which can significantly increase the total obligation. Always consult with a Navy Federal loan officer for an official, final quote.
How to Calculate Mortgage Payment (Example)
Let’s calculate the monthly payment for a $200,000 loan at 5% interest over 30 years:
- Determine Monthly Interest Rate (i): Divide the annual rate by 12 and 100. (5 / 100) / 12 = 0.00416667.
- Determine Total Number of Payments (n): Multiply the loan term by 12. 30 years * 12 = 360 payments.
- Calculate the Numerator (N): $i * (1 + i)^n$. $0.00416667 * (1.00416667)^{360} \approx 0.026615$.
- Calculate the Denominator (D): $(1 + i)^n – 1$. $(1.00416667)^{360} – 1 \approx 4.3839$.
- Calculate the Monthly Factor (F): Divide the Numerator by the Denominator. $0.026615 / 4.3839 \approx 0.006071$.
- Calculate Monthly Payment (M): Multiply the Principal (P) by the Monthly Factor (F). $200,000 * 0.006071 = \$1,214.20$.
Frequently Asked Questions (FAQ)
Is the Navy Federal mortgage rate better than other banks?
Navy Federal, as a credit union, is member-owned and often offers competitive rates and lower fees than traditional banks. However, rates constantly change, so it’s always recommended to compare their quoted rate with at least two other lenders to find the best deal.
What is PITI?
PITI stands for Principal, Interest, Taxes, and Insurance. It represents the total cost of homeownership paid monthly. This calculator focuses only on the P&I portion.
Do I need a down payment for a Navy Federal loan?
Navy Federal offers several options, including VA loans (for qualified members) which typically require $0 down payment. Conventional loans, however, usually require a down payment ranging from 3% to 20%.
What term (years) should I choose?
A 30-year term offers lower monthly payments but results in significantly more total interest paid. A 15-year term has higher monthly payments but saves a substantial amount on interest over the life of the loan. The best choice depends on your budget and financial goals.
