Commercial Rent Per Square Foot Calculator: Annual Rate From Total

Work out the rent per square foot per year on a commercial lease — the standard unit commercial brokers quote and the figure for comparing leases on equal terms.

Amount & Quantity
$
Total annual base rent (not including operating expenses or NNN charges).
Leasable square footage as defined in the lease. Some leases use rentable area (RA), which is larger than usable area (UA).

Compare Common Scenarios

How the numbers shift across typical situations for this calculator:

ScenarioRent 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

Unit Cost = Total Amount / Quantity

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).

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

Ugo Candido ✓ Editor
Founder & Editor-in-Chief at CalcDomain — responsible for the methodology, sourcing, and technical review of this calculator.

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.
