Commercial Lease Tools & Resources

Enter your lease terms in per-square-foot format — how landlords actually quote space — and see your real annual cost year by year. Inputs: base rent $/sqft/year, square footage, lease term, annual escalation, CAM $/sqft/year, CAM growth rate. Output: year-by-year table plus total cost over the full lease term.

Already know your monthly rent and CAM in dollar terms? Enter base rent per month, annual escalation rate, monthly CAM charges, and lease term to see a full year-by-year cost breakdown and total occupancy cost over the lease. Useful when your lease or LOI quotes flat monthly amounts rather than per-sqft rates.
