How to use the estimate
The calculator treats base and additional rent as annual amounts per unit of rentable area, then adds monthly recurring costs. One-time tenant costs are shown separately and spread across the entered term for a simple equivalent monthly view.
It does not model rent escalation, tax on payments, financing, depreciation, present value, operating-cost reconciliations or end-of-term restoration. Use the lease-comparison calculator for two scenarios and the escalation calculator for changing rent.
Planning estimate only: Verify lease definitions, measurement, tax, utilities, operating costs, incentives, dates and local legal treatment. Results are not a quotation or valuation.
