What is the VA Mortgage Calculator?
This calculator is for United States VA home loans backed by the U.S. Department of Veterans Affairs. VA loans let eligible veterans, active-duty service members and surviving spouses buy a home with little or no down payment. Most borrowers pay a one-time VA funding fee, which is commonly rolled into (financed with) the loan rather than paid in cash. This tool estimates your monthly principal-and-interest payment, the financed loan amount, the funding fee dollar amount, and total interest over the life of the loan.
Note: estimates exclude property taxes, homeowners insurance and HOA dues. Funding fee percentages vary by service category, down payment and whether it is your first VA loan; check current VA rules for your exact rate.
How to use it
Enter the home price, your down payment, the annual interest rate, the loan term in years, and your VA funding fee percentage. The calculator subtracts the down payment to find the base loan, adds the financed funding fee, then amortizes the total.
The formula explained
First the financed principal is \(P = L + L \cdot f\), where L is the base loan and f is the funding fee rate. Then the monthly payment uses the amortization formula $$M = \frac{P \cdot r (1+r)^n}{(1+r)^n - 1}$$ with monthly rate \(r = \text{annual rate} \div 12\) and \(n = \text{years} \times 12\).
Worked example
Home price $300,000, $0 down, 6.5% interest, 30 years, 2.15% funding fee. Base loan = $300,000, funding fee = $6,450, so \(P = \$306{,}450\). With \(r = 0.0054167\) and \(n = 360\), the monthly payment is about $1,937.05.
FAQ
Is the funding fee always financed? No — you can pay it upfront in cash, but many borrowers roll it into the loan, which this calculator assumes.
Who is exempt from the funding fee? Veterans receiving VA disability compensation and certain surviving spouses are usually exempt; set the funding fee to 0% in that case.
Does this include taxes and insurance? No, it shows only principal and interest. Add escrow amounts separately to estimate your full payment.
