Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Rent per square foot per year |
|---|---|
| $48k / 2,000 sq ft ($24/sf) | $24.00 |
| $180k / 4,000 sq ft (premium office) | $45.00 |
| $30k / 5,000 sq ft (warehouse) | $6.00 |
| $120k / 3,000 sq ft (Class A) | $40.00 |
How This Calculator Works
Enter total annual base rent and leasable square footage. The calculator divides one by the other to give the rent per square foot per year — the conventional commercial real estate metric. Add NNN operating expenses for an all-in cost-of-occupancy comparison.
The Formula
Cost per Unit
Total Amount is the full cost or price, Quantity is the number of units it covers
Worked Example
$48,000 of annual rent on 2,000 leased square feet works out to $24 per square foot per year. US 2024 medians: Class A office in major metros $35 to $90+ per sq ft; Class B office $20 to $45; suburban retail $15 to $40; industrial warehouse $6 to $15. Coastal metros (NYC, SF, LA) routinely 50% to 100% above national medians.
Key Insight
Commercial rent per square foot is misleading without the NNN context. A $20/sq ft 'gross' lease (landlord pays operating expenses) and a $14/sq ft 'NNN' lease ($6 in passthroughs) can have the same all-in cost. Always normalize to all-in occupancy cost ($/sq ft including NNN, plus tenant improvements amortized over the term, plus any concessions like free rent) before comparing leases.
Commercial rent/sqft fundamentals 2024
TYPICAL RANGES (annual/sqft).
Office Class A: $35-$80+ (gateway cities higher).
Office Class B/C: $20-$40.
Retail (strip): $15-$40.
Retail (prime/mall): $40-$100+.
Industrial/warehouse: $5-$15.
Flex/R&D: $12-$30.
Medical office: $25-$55.
LEASE TYPES.
Gross: landlord pays opex.
NNN (triple-net): tenant pays tax + insurance + CAM.
Modified gross: split.
Full-service: all-inclusive.
LOAD FACTOR.
Rentable = usable + common-area share.
Load factor 10-20% typical.
Quote on rentable; occupy usable.
NNN + concessions + market
NNN BREAKDOWN.
Base rent + taxes + insurance + CAM.
CAM: $3-$15/sqft additional.
Tenant must model all-in occupancy cost.
CONCESSIONS.
TI allowance: $10-$100/sqft (landlord-funded buildout).
Free rent: 1-6 mo (lease-up incentive).
Effective rent < face rent.
ESCALATIONS.
Annual bumps 2-3% or CPI.
Stepped increases.
MARKET 2024.
Office vacancy elevated post-COVID (15-20%+).
Repricing + concessions in many markets.
Industrial strong (e-commerce).
Retail recovering.
CBRE + BOMA data.
BENCHMARKING.
Compare like-for-like (lease type + class + submarket).
Effective rent for true cost.

NNN vs gross lease distinction critical for all-in cost. Load factor inflates rentable vs usable. TI allowance + free rent reduce effective rent. Office repricing post-COVID. CBRE + BOMA + FRED data.
Frequently Asked Questions
How is commercial rent per square foot calculated?
Divide total annual base rent by leasable square footage. $48,000 across 2,000 sq ft is $24 per sq ft per year.
What is NNN?
Triple net — the tenant pays base rent plus three categories of operating expenses: property taxes, insurance, and common area maintenance (CAM). NNN rates look lower than gross rates because operating expenses are billed separately.
What are typical rates?
US 2024 medians: Class A office in major metros $35 to $90/sq ft; Class B office $20 to $45; suburban retail $15 to $40; industrial warehouse $6 to $15. Coastal metros 50% to 100% above national medians.
Rentable vs usable area?
Usable area is the actual square footage of your space. Rentable area includes a share of common areas (lobbies, hallways) — typically 10% to 25% larger than usable. Commercial leases quote on rentable area; budget on usable area for actual space planning.
How do tenant improvements factor in?
Landlords often provide tenant improvement allowances ($20 to $100/sq ft) for build-out. Amortize that allowance against the lease term and subtract from the effective rent for a true all-in cost — a $30/sq ft rate with $50/sq ft TI allowance over 10 years effectively costs $25/sq ft.
When is this calculator unreliable?
Less reliable when NNN (tenant pays taxes/insurance/CAM) vs gross vs modified gross, when CAM charges + operating expense pass-throughs, when load factor (rentable includes common-area share, usable is actual), when market variance (SF/NYC office $60-$100 vs secondary $20-$30), when tenant improvement (TI) allowance + free rent concessions, when escalation clauses (annual bumps), when Class A vs B vs C, or when post-COVID office vacancy + repricing.

Methodology & Review
Commercial rent/sqft = annual rent ÷ rentable square feet. U.S. 2024: office $20-$80/sqft/yr (Class A vs B/C, market-dependent); retail $15-$100+/sqft; industrial $5-$15/sqft; NNN vs gross lease distinction critical; CAM charges; load factor (rentable vs usable). RELIABILITY: Reliable for the division. Less reliable for (a) NNN (tenant pays taxes/insurance/CAM) vs gross vs modified gross, (b) CAM charges + operating expense pass-throughs, (c) load factor (rentable includes common-area share, usable is actual), (d) market variance (SF/NYC office $60-$100 vs secondary $20-$30), (e) tenant improvement (TI) allowance + free rent concessions, (f) escalation clauses (annual bumps), (g) Class A vs B vs C, (h) post-COVID office vacancy + repricing.
