Navy Federal Credit Union Mortgage Calculator Formula
The monthly principal and interest (P&I) payment is calculated using the standard amortization formula:
$$ M = P \frac{r(1+r)^n}{(1+r)^n – 1} $$Where:
- \(M\) = Monthly Payment (P&I)
- \(P\) = Principal Loan Amount (Home Price – Down Payment)
- \(r\) = Monthly Interest Rate (Annual Rate / 12 / 100)
- \(n\) = Total Number of Payments (Loan Term in Years × 12)
The full monthly payment (PITI) is then calculated as: $PITI = M + (Annual Taxes + Annual Insurance) / 12$.

Understanding the inputs is key to an accurate estimate:
- Home Price: The total agreed-upon purchase price of the property.
- Down Payment: The upfront cash amount you contribute, reducing the loan principal.
- Annual Interest Rate (%): The rate charged on the loan balance, expressed as an annual percentage.
- Loan Term (Years): The duration over which you will repay the loan (e.g., 15 or 30 years).
- Annual Property Taxes: The yearly tax assessment on the property, which is usually escrowed and paid monthly.
- Annual Home Insurance: The yearly premium for homeowners insurance, also typically escrowed and paid monthly.

How to Calculate a Monthly Mortgage Payment (Example)
Let’s use a standard 30-year fixed-rate mortgage example:
- Determine Loan Principal ($P$): Home Price of $300,000 with a $60,000 down payment results in a principal of $240,000.
- Find Monthly Rate ($r$): An annual rate of $6\%$ is $0.06 / 12 = 0.005$ (or $0.5\%$).
- Find Total Payments ($n$): A 30-year term is $30 \times 12 = 360$ payments.
- Calculate P&I ($M$): Plug the values into the amortization formula: $M = 240,000 \times \frac{0.005(1+0.005)^{360}}{(1+0.005)^{360} – 1} \approx \$1,438.92$.
- Calculate PITI: Add monthly escrow costs. If annual taxes are $3,600$ and insurance is $1,200$, the monthly escrow is $(\$3,600 + \$1,200) / 12 = \$400$.
- Final PITI: $\$1,438.92$ (P&I) + $\$400.00$ (T&I) = $\$1,838.92$.
Frequently Asked Questions (FAQ)
What is PITI?
PITI stands for Principal, Interest, Taxes, and Insurance. It represents the full monthly cost of owning a home and is the figure most lenders use to assess affordability.
How does my credit score affect the calculation?
Your credit score directly impacts the Annual Interest Rate (%) you qualify for. A higher score typically results in a lower rate, significantly reducing your monthly interest payment.
Do I have to include taxes and insurance in the payment?
If your down payment is less than $20\%$, Navy Federal (like most lenders) will typically require you to escrow taxes and insurance, meaning these amounts are collected monthly and held by the lender to pay the bills when due.
What is Private Mortgage Insurance (PMI)?
PMI is a type of insurance required when the loan-to-value (LTV) ratio is greater than $80\%$ (i.e., less than a $20\%$ down payment). This calculator does not include PMI, so your actual payment may be higher if you put down less than $20\%$.
