Commercial Lease Formula
The basic commercial lease calculation multiplies the rentable area by the rent rate per unit of area.
Total\ Rent = Total\ Area * Rent\ Rate
To solve for total area:
Total\ Area = Total\ Rent / Rent\ Rate
To solve for rent rate:
Rent\ Rate = Total\ Rent / Total\ Area
- Total Rent is the lease amount for the selected time period, such as monthly rent or annual rent.
- Total Area is the size of the leased space, entered in square feet or square meters.
- Rent Rate is the price per unit of area, entered as dollars per square foot or dollars per square meter.
The calculator lets you enter any two values and calculate the third. If you enter area and rent rate, it calculates total rent. If you enter total rent and rent rate, it calculates the required area. If you enter total rent and area, it calculates the rent rate.
Area units are converted using:
1\ m^2 = 10.7639\ ft^2
Rent rate and total rent must use the same time basis. For example, if the rent rate is annual, the total rent result is annual. If the rent rate is monthly, the total rent result is monthly.
Common Commercial Lease Rate Time Bases
| Rate Quoted As | Usually Means | Example for 2,000 ft² |
|---|---|---|
| $25 per ft² per year | Annual rent rate | 2,000 × 25 = $50,000 per year |
| $2.50 per ft² per month | Monthly rent rate | 2,000 × 2.50 = $5,000 per month |
| $270 per m² per year | Annual rent rate using square meters | Area must be entered or converted consistently |
Area Unit Conversions for Lease Calculations
| Conversion | Value |
|---|---|
| 1 square meter to square feet | 10.7639 ft² |
| 1 square foot to square meters | 0.092903 m² |
| $/m² to $/ft² | Divide by 10.7639 |
| $/ft² to $/m² | Multiply by 10.7639 |
Commercial Lease Calculation Examples
Example 1: Calculate total rent
You lease 3,000 ft² at $18 per ft² per year.
Total\ Rent = 3000 * 18 = 54000
The total rent is $54,000 per year.
Example 2: Calculate rent rate
A 1,500 ft² space has total rent of $4,500 per month.
Rent\ Rate = 4500 / 1500 = 3
The rent rate is $3 per ft² per month.
Commercial Lease Calculator FAQ
Is commercial rent usually quoted monthly or yearly?
It depends on the market and property type. Many commercial leases quote rent as dollars per square foot per year, especially office, retail, and industrial leases. Some listings quote monthly rent or monthly price per square foot. Always keep the rent rate and total rent on the same time basis.
Does this calculate extra costs like CAM, taxes, or insurance?
No. This calculation only uses area and rent rate. It does not include common area maintenance charges, property taxes, insurance, utilities, percentage rent, parking, or other pass-through costs. If those costs apply, add them separately after calculating the base rent.
What area should I use for a commercial lease?
Use the area that matches the rent rate in the lease or listing. Commercial leases may use rentable square feet, usable square feet, gross leasable area, or square meters. If the quoted rate is based on rentable area, enter rentable area rather than usable area.
