NYC Commercial Lease Cost Calculator
Estimate the total cost of your NYC commercial lease including base rent, operating expenses (NNN), utilities, and the NYC Commercial Rent Tax (CRT) where applicable.
Formulas Used
Annual Base Rent (Year N):
Base RentN = (Base Rent/sq ft) × (Sq Ft) × (1 + Escalation Rate)N−1
Annual Operating Expenses:
OpEx = (NNN Rate/sq ft) × (Sq Ft) — constant each year unless renegotiated
Annual Utilities:
Utilities = Monthly Utilities × 12
NYC Commercial Rent Tax (CRT):
— Applies only to Manhattan tenants below 96th St with annual base rent ≥ $250,000
— Full rate: CRT = Annual Base Rent × 3.9%
— Phase-in credit (rents $250,000–$300,000): CRT = Full CRT × [(Annual Rent − $250,000) / $50,000]

Annual Total Cost (Year N):
TotalN = Base RentN + OpEx + Utilities + CRTN
Total Lease Cost:
Total = Σ Annual TotalN for N = 1 to Lease Term
Net Cost After TIA:
Net Cost = Total Lease Cost − Tenant Improvement Allowance
Effective Cost per Sq Ft per Year:
= Net Cost / (Sq Ft × Lease Term)
Assumptions & References
- Base rent escalation is compounded annually beginning in Year 2 (Year 1 = stated rate).
- NNN / operating expenses are held constant over the lease term; actual leases may include expense stop provisions or caps.
- Utilities are estimated and held constant; actual costs vary by usage, season, and utility provider (Con Edison, National Grid).
- NYC Commercial Rent Tax rate of 3.9% applies to Manhattan tenants (below 96th St) with annual base rent ≥ $250,000. A phase-in tax credit reduces liability for rents between $250,000 and $300,000. Source: NYC Admin Code § 11-701 et seq.; NYC Dept of Finance CRT filing requirements.
- Tenants in Manhattan at or above 96th St and all outer-borough tenants are exempt from CRT per NYC Admin Code § 11-704(c).
- Tenant Improvement Allowance (TIA) is treated as a one-time upfront credit reducing total occupancy cost; it does not affect annual rent calculations.
- This calculator does not account for: NYC Real Property Transfer Tax, broker commissions (typically 3–6% of total lease value), legal fees, security deposits, or personal property taxes.
- Typical Manhattan Class A office rents: $70–$150/sq ft/yr; Class B: $45–$80/sq ft/yr (CBRE, Cushman & Wakefield market reports, 2024).
- Typical NNN charges in NYC: $15–$30/sq ft/yr depending on building class and location.
