Office Space Planning: How to Calculate Your True Cost per Seat

Office space is typically the second-largest expense for businesses after payroll. Accurately calculating your total cost per employee helps you make informed decisions about how much space to lease, where to locate, and whether alternatives like coworking spaces or remote work might be more cost-effective. Understanding the full picture goes beyond the quoted lease rate and includes operating expenses, buildout costs, and amenities like parking.

How Much Space Do You Need per Employee?

The amount of office space needed per employee varies significantly based on your industry, work style, and office layout. Traditional private offices typically require 200-300 square feet per person. Open-plan offices with assigned desks average 100-150 square feet per person. Hot-desking or hybrid arrangements can reduce this to 60-80 square feet per person since not all employees are in the office on any given day. When calculating total square footage, remember to account for common areas including conference rooms, break rooms, reception areas, and hallways, which typically add 30-40% to your usable workspace.

Cost per Seat Benchmarks by Market

Office costs vary dramatically by market. In major cities like New York and San Francisco, the total cost per seat (including all operating expenses) can exceed $1,500 per employee per month. Secondary markets like Austin, Denver, and Nashville typically range from $600 to $1,000 per seat per month. Smaller metros and suburban locations can offer costs as low as $300 to $500 per employee per month. These benchmarks include the lease rate, operating expenses, amortized buildout costs, and parking. Compare your calculated cost per employee to market benchmarks to determine if you are getting a competitive deal.

Tenant Improvements and Buildout Costs

Buildout costs for office space typically range from $50 to $200 per square foot depending on the scope of work. A basic refresh with paint and carpet might cost $20 to $40 per square foot, while a full buildout with new walls, electrical, plumbing, and high-end finishes can exceed $150 per square foot. Many landlords offer a Tenant Improvement (TI) allowance of $30 to $80 per square foot as part of the lease negotiation, which offsets a portion of buildout costs. Amortizing your out-of-pocket buildout cost over the lease term gives you a more accurate picture of your monthly occupancy expense.

How to Reduce Office Space Costs

• Implement hybrid work. If employees work from home 2-3 days per week, you can reduce your space needs by 30-40% through desk sharing and hot-desking arrangements.
• Negotiate aggressively on lease terms. In addition to the base rent, negotiate for a higher TI allowance, free rent periods, capped annual escalations, and flexible termination clauses.
• Consider subleasing unused space. If you have more space than you need, subleasing to another company can offset a significant portion of your costs.
• Evaluate coworking for small teams. For companies with fewer than 15-20 employees, coworking spaces often provide a lower total cost when you factor in furniture, internet, utilities, and common area amenities that are included in the membership.
• Choose the right market. If your workforce is remote-capable, consider locating your office in a secondary market where lease rates are 40-60% lower than major metros.
• Right-size your conference rooms. Conference rooms are often the most underutilized space in an office. Use booking data to determine how many you actually need, and convert excess rooms into workstations or collaboration areas.
