Understanding Commercial Lease Rates (SF/Year)

Commercial real estate leasing operates differently from residential rentals. While an apartment lease typically quotes a flat monthly price (e.g., "$2,000 per month"), commercial spaces—including office, retail, and industrial properties—are usually quoted as an Annual Rate per Square Foot.

This Rental Rate SF/Year Calculator helps tenants, brokers, and landlords quickly convert these annual square-footage metrics into actual monthly budgets.

The Golden Formula:
(Total Square Feet × Annual Rate per SF) ÷ 12 = Monthly Base Rent

How to Read a Quote: $25.00/SF/Year

If you see a listing for an office space priced at $25.00/SF/Year, this does not mean the rent is $25 a month. It means you pay $25.00 for every square foot of space you occupy over the course of a full year.

Example Calculation:
If you are leasing a 2,000 sq. ft. office at $25.00/SF:

• Annual Base Rent: 2,000 sq. ft. × $25.00 = $50,000 per year.
• Monthly Base Rent: $50,000 ÷ 12 months = $4,166.67 per month.

Additional Costs: CAM and NNN

Base rent is often just the starting point. Many commercial leases are "Triple Net" (NNN) or involve "CAM" (Common Area Maintenance) fees. These are additional operating expenses passed on to the tenant, covering things like property taxes, insurance, and building maintenance.

In our calculator, you can input the estimated CAM/NNN per sq. ft. to see your true total monthly occupancy cost.

• Base Rent: Goes to the landlord as revenue.
• CAM/NNN: Reimbursements for building operations.
• Gross Rent: The sum of Base Rent + CAM, usually what you actually write on the check.

Commercial vs. Residential Calculations

Confusion often arises when moving from residential to commercial markets. In some regions (like California or parts of the industrial market), rent might be quoted as $/SF/Month rather than per year.

To convert a Monthly SF rate to an Annual SF rate, simply multiply by 12. For example, $2.00/SF/Month is equivalent to $24.00/SF/Year. Ensure you know which metric the landlord is using before signing a Letter of Intent (LOI).
