About Office Space Cost Calculator
The Office Space Cost Calculator prices out workspace from the two figures commercial leases are quoted in: the area you need and the annual rate per square foot. It multiplies them to produce the yearly cost and also shows the monthly equivalent.
Because office rates are quoted per square foot per year, the total can surprise tenants who think in monthly terms — this calculator converts the quoted rate into both the annual and monthly dollar amounts before you commit to a lease.
Enter the space and the rate, press Calculate, and read the yearly cost with the monthly breakdown.
Formula & Mathematical Calculation
Annual Cost = Space (sq ft) × Rate ($/sq ft/year)
Monthly Cost = Annual Cost ÷ 12
Exactly the two fields on this form. The engine multiplies directly with no validation branch.
Calculation Example
For 1,200 sq ft of space at a rate of $28 per sq ft per year, the annual cost is 1,200 × $28 = $33,600, which breaks down to $33,600 ÷ 12 = $2,800 per month.
Key Benefits
- Converts a per-square-foot lease quote into actual annual and monthly dollar amounts.
- Uses exactly the two numbers a commercial listing provides, with no assumptions layered on top.
- Shows the monthly figure so the cost can be compared directly against a monthly budget.
- Computes a straight multiplication and division, so the output is fully determined by your inputs.

Enter the space
Type the square footage you need in the Space (sq ft) field, for example 1200. -
Enter the rate
Type the quoted annual rate in the Rate ($/sq ft/year) field, for example 28. Use the per-year figure the listing states. -
Press Calculate
