The fixed minimum monthly or annual payment a commercial tenant owes the landlord, before any additional charges for operating expenses, taxes, or insurance. Base rent is the starting point for calculating total occupancy cost.
Base rent is usually expressed as a dollar amount per rentable square foot (RSF) per year. For example, a lease at $30/RSF on a 5,000 RSF space means $150,000 per year, or $12,500 per month. Most commercial leases include scheduled increases to base rent over the term, either as fixed dollar bumps, fixed percentage increases, or CPI-linked adjustments. Accurate extraction of base rent is critical because it serves as the foundation for calculating holdover penalties, security deposit requirements, and overall lease value.
