#### Formulas Used
Monthly Payment (M):
M = P × [r(1 + r)n] / [(1 + r)n − 1]
- P = Loan principal ($)
- r = Monthly interest rate = Annual Rate / 12 / 100
- n = Total amortization months = Amortization Period × 12
Balloon Payment (B) — remaining balance after loan term months (nTerm):
B = P × (1 + r)nTerm − M × [(1 + r)nTerm − 1] / r
Loan-to-Value (LTV):
LTV = (Loan Amount / Property Value) × 100
Debt Service Coverage Ratio (DSCR):
DSCR = Annual NOI / Annual Debt Service (Monthly Payment × 12)
#### Assumptions & References
- Commercial mortgages in New Jersey typically feature a balloon payment at the end of the loan term (e.g., 5, 10, or 25 years) with a longer amortization period (e.g., 25–30 years).
- New Jersey commercial lenders generally require a minimum DSCR of 1.25x, meaning NOI must be at least 125% of annual debt service.
- Typical NJ commercial LTV ratios range from 65%–80% depending on property type and lender.
- This calculator does not include NJ-specific closing costs such as the New Jersey Realty Transfer Fee, mortgage recording fees, title insurance, or environmental assessments.
- New Jersey imposes a Commercial Mortgage Recording Tax on mortgages over $10,000 — consult a NJ real estate attorney for current rates.
- Formula reference: Standard mortgage amortization — Investopedia: Amortization; DSCR — FDIC Commercial Real Estate Lending Guidelines.
