Expense Stop Reconciliation Calculator

Calculate a tenant share of operating expenses above a base-year stop. Enter your own assumptions and local rates.

What this calculator estimates

Calculate a tenant share of operating expenses above a base-year stop. It combines the inputs below to produce Year-end reconciliation. 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 $2,000. This is an illustration, not a market quote. Change one input at a time to understand what drives the result.

Inputs and assumptions

• Tenant rentable area — sample input: 5000 sq. ft.
• Building rentable area — sample input: 50000 sq. ft.
• Current building operating expenses — sample input: 600000 currency units
• Base-year operating expenses — sample input: 500000 currency units
• Annual tenant cap — optional — sample input: 0 currency units
• Estimated recoveries already paid — sample input: 8000 currency units

How to interpret the result

Compare full lease economics rather than face rent alone. Compare a conservative case with an expected case and keep a record of the assumptions used.

Common mistake to avoid

Do not omit incentives, recoveries, commissions or escalation. Local definitions, taxes, lending practices and measurement requirements can materially change the result.
