Florida Commercial Lease Cost Calculator
Estimate your total monthly and annual commercial lease costs in Florida, including base rent, Common Area Maintenance (CAM) charges, Florida sales tax on commercial rent, insurance, and property taxes.
Formulas Used
Annual Base Rent (Year N):
Base Rent = Square Footage × Base Rate × (1 + Escalation%)^(N−1) − Free Rent Credit
Free Rent Credit:
Credit = (Monthly Base Rent) × Free Rent Months Applied in Year N
NNN Charges (annual):
NNN = Square Footage × (CAM + Insurance + Property Tax Pass-Through) per sq ft per year
Florida Sales Tax:
Sales Tax = (Net Base Rent + NNN) × (State Rate 2.0% + Local Surtax 1.0%) = × 3.0%
Per Florida Statute §212.031 — sales tax applies to total rent including NNN pass-throughs.
Total Annual Cost:
Annual Total = Net Base Rent + NNN + Florida Sales Tax
Security Deposit:
Security Deposit = (Base Rate × Sq Ft / 12) × Security Deposit Months
Effective Monthly Cost:
Effective Monthly = Total Lease Cost ÷ (Lease Term in Years × 12)
Assumptions & References
- Florida Sales Tax Rate: 2.0% state rate effective June 1, 2024 (reduced from 4.5% per HB 7073 / Florida DOR TIP #24A01-01). A representative 1.0% local county surtax is added for a combined 3.0% — actual local surtax varies by county (0%–1.5%).
- Sales Tax Base: Under Florida Statute §212.031, sales tax applies to total rent consideration, including NNN pass-throughs (CAM, insurance, property taxes).
- NNN Charges: CAM, insurance, and property tax pass-throughs are assumed flat (not escalated) over the lease term, which is common in Florida triple-net leases.
- Escalation: Annual rent escalation applies to base rent only, compounded annually from Year 1.
- Free Rent: Applied to base rent only (not NNN or sales tax), consumed from the start of the lease term.
- Security Deposit: Calculated on first-month base rent only; actual deposit terms vary by landlord.
- Lease Type: This calculator models a Triple-Net (NNN) lease structure, the most common commercial lease type in Florida.
