Commercial Real Estate Principles

Understanding Percentage Rent & NNN

Key retail and restaurant commercial lease principles:

  • The 6% to 10% Occupancy Rule: Restaurants and retailers aiming for long-term survival must keep total occupancy costs under 10% of gross sales.
  • Natural vs. Artificial Breakpoints: A natural breakpoint aligns percentage rent with the exact point where sales overage equals base rent. Artificial breakpoints specify an arbitrary lower sales hurdle.
  • Triple Net (NNN) Pass-Throughs: CAM charges, property taxes, and insurance add $8 to $20+ per square foot on top of base rent.
  • Downside Protection for Landlords: Base minimum rent guarantees debt service coverage for landlords during recessions.

Mathematical Formulation

Commercial lease equations

Annual_Base_Rent = SqFt × Base_Rent_PSF

Annual_NNN_Expenses = SqFt × NNN_CAM_PSF

Natural_Breakpoint = Annual_Base_Rent / Percentage_Rent_%

Overage_Sales = max( 0, Gross_Sales - Natural_Breakpoint )

Percentage_Rent_Due = Overage_Sales × Percentage_Rent_%

Total_Occupancy_Cost = Base_Rent + NNN_Expenses + Percentage_Rent

Occupancy_Ratio_% = ( Total_Occupancy_Cost / Gross_Sales ) × 100%

FAQ

Commercial lease & percentage rent questions

What is Percentage Rent in commercial real estate?

Percentage rent is a lease provision where a tenant pays a base minimum rent plus a percentage of gross sales exceeding a specified sales threshold (breakpoint).

What is a Natural Breakpoint in a retail or restaurant lease?

A natural breakpoint is the exact gross sales level where the percentage rent rate equals the base minimum rent: Natural Breakpoint = Annual Base Rent ÷ Percentage Rent Rate.

What are Triple Net (NNN) CAM charges?

Under a Triple Net (NNN) lease, the tenant pays base rent plus their proportional share of Common Area Maintenance (CAM), real estate property taxes, and building insurance.

What is a healthy Occupancy Cost Ratio for restaurants and retail?

For full-service restaurants, a healthy occupancy cost ratio is 6% to 8% of gross sales. For fast casual and retail, 8% to 10% is typical. Exceeding 12% indicates severe financial risk.

Can I export the commercial lease audit and sensitivity matrix to CSV?

Yes. You can export complete base rent schedules, NNN pass-through expenses, natural breakpoints, and 6x5 sensitivity tables as a UTF-8 CSV spreadsheet with formula defense.
