Module C: Formula & Methodology Behind the Calculator
Our calculator uses sophisticated financial algorithms tailored to San Luis Obispo’s commercial lending environment:
1. Monthly Payment Calculation
For fully amortizing loans:
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]
Where:
M = monthly payment
P = principal loan amount
i = monthly interest rate (annual rate ÷ 12)
n = number of payments (loan term in months)
2. Balloon Payment Calculation
For loans with balloon payments:
Balloon = P × (1 - [ (1 + i)^n - (1 + i)^m ] / [ (1 + i)^n - 1 ])
Where m = number of payments before balloon
3. Debt Service Coverage Ratio (DSCR)
Critical metric for SLO County lenders:
DSCR = Net Operating Income / Annual Debt Service
Minimum requirements:
– Traditional banks: 1.20-1.25
– Credit unions: 1.15-1.20
– Private lenders: 1.05-1.15
4. Local Market Adjustments
Our calculator incorporates:
– 0.25% rate premium for properties in high-risk flood zones (common in Morro Bay)
– 0.15% discount for LEED-certified buildings (increasingly common in downtown SLO)
– Additional 0.5% for properties requiring environmental remediation
