Formula Used in USDA Loan Calculation
This calculator uses a standard loan amortization formula, widely used in mortgage calculations.
1. Total Project Cost
Total Cost = Home Construction Cost + Land Cost
2. Loan Amount
Loan Amount = Total Cost − Down Payment
3. Monthly Interest Rate
Monthly Rate = Annual Interest Rate ÷ 100 ÷ 12
4. Loan Term in Months
Months = Years × 12
5. Monthly Payment Formula
The EMI (Equated Monthly Installment) is calculated using:
M=1−(1+r)−nP⋅r
Where:
- M = Monthly payment
- P = Loan amount
- r = Monthly interest rate
- n = Total number of months
If Interest Rate is 0
If no interest is applied:
Monthly Payment = Loan Amount ÷ Number of Months
Example Calculation
Let’s understand with a real-life example:
Inputs:
- Home Construction Cost = $200,000
- Land Cost = $50,000
- Down Payment = $30,000
- Interest Rate = 6%
- Loan Term = 25 years
Step 1: Total Cost
Total Cost = 200,000 + 50,000 = $250,000
Step 2: Loan Amount
Loan Amount = 250,000 − 30,000 = $220,000
Step 3: Monthly Interest Rate
6% ÷ 12 = 0.5% monthly = 0.005
Step 4: Loan Term
25 × 12 = 300 months
Step 5: Monthly Payment
Approximate Monthly Payment ≈ $1,415 (based on amortization formula)
