Recovery of past CAM overcharges depends on your specific lease terms, including any audit rights deadlines or ‘binding and conclusive’ provisions, and on applicable state law.

State statute of limitations periods apply to written contracts and range from 3 to 10 years. Your actual lookback window may be shorter based on your lease.

Percentage Rent vs Flat Rent

Last updated: April 2026

By Angel Campa, Founder

Percentage rent ties your rent to sales performance while flat rent stays constant. Neither changes your CAM audit needs, which depend on your pass-through structure.

Percentage Rent

Percentage rent requires the tenant to pay a base rent plus a percentage of gross sales above a specified breakpoint. Common in retail leases, this structure ties landlord revenue to tenant business performance, aligning incentives around foot traffic and property quality.

Advantages

  • ✓Lower base rent reduces fixed costs during slow sales periods
  • ✓Aligns landlord incentive to maintain property quality and drive traffic
  • ✓Scales with business success rather than imposing flat overhead

Disadvantages

  • ✗Successful tenants pay significantly more than under flat rent
  • ✗Requires sharing detailed sales data with the landlord
  • ✗Breakpoint calculations and reporting obligations add administrative complexity

Flat Rent

Flat rent is a fixed monthly amount that does not change based on tenant sales volume. The tenant pays the same rent regardless of business performance, with increases typically limited to scheduled escalations outlined in the lease.

Advantages

  • ✓No obligation to share sales data with the landlord
  • ✓Cost certainty allows precise financial forecasting
  • ✓High-revenue tenants keep 100% of sales above expenses

Disadvantages

  • ✗Higher base rent locks in costs during slow periods
  • ✗No built-in mechanism for rent relief during downturns
  • ✗Landlord has less financial incentive to invest in property improvements

How This Affects Your CAM Charges

Percentage rent does not directly affect CAM charges, but tenants paying percentage rent often also have NNN or modified gross CAM obligations. The combined burden of percentage rent and pass-through expenses makes CAM accuracy even more critical, since every dollar of overcharge compounds on an already variable cost structure.

Which Exposes You to More Risk?

For CAM overcharge risk specifically, both structures carry the same exposure because CAM charges are calculated independently from rent. However, tenants paying percentage rent already face variable costs from the sales-based component, so unexpected CAM overcharges on top of percentage rent create compounding budget uncertainty.
