Commercial Lease Commission Calculator

Estimate brokerage commission from rent, term and commission rate. Replace every default with figures that apply to your property and location.

What this calculator estimates

Estimate brokerage commission from rent, term and commission rate. It combines the inputs below to produce Estimated lease commission. Every assumption remains editable so the estimate can reflect the property, financing and location being evaluated.

Worked example

Using the displayed sample assumptions, the calculator produces $24,000. This is an illustration, not a market quote. Change one input at a time to understand what drives the result.

Inputs and assumptions

• Leased area — sample input: 5000 sq. ft.
• Annual rent per area unit — sample input: 24 currency units per sq. ft.
• Lease term — sample input: 5 years
• Commission rate on base rent — sample input: 4 %

How to interpret the result

Use lease definitions and verified operating statements. Compare a conservative case with an expected case and keep a record of the assumptions used.

Common mistake to avoid

Do not compare properties using inconsistent NOI definitions. Local definitions, taxes, lending practices and measurement requirements can materially change the result.
