How to use this calculator
Enter the home price, interest rate, loan term, and yearly property tax and insurance. The calculator assumes the common USDA setup: no down payment, the 1% upfront guarantee fee financed into the loan, and the 0.35% annual fee divided into monthly payments.
The formula
Loan amount = price × 1.01 (1% upfront fee financed). Principal and interest use the standard amortization formula M = L × r(1+r)^n ÷ ((1+r)^n − 1), with r = annual rate ÷ 12. Monthly payment = P&I + loan × 0.35% ÷ 12 + tax ÷ 12 + insurance ÷ 12.
Example: $300,000 at 6.5% for 30 years
Loan with financed fee: $303,000 → P&I ≈ $1,915.26. Annual fee: $88.38/mo. With $300/mo tax and $100/mo insurance, total ≈ $2,403.64 per month.
