How the math works

Gross sales rent = max(% of sales, floor). Common in mall kiosks, pop-ups, and short-term licenses.

LLs always want a floor; tenants push for pure %. Compromise is a modest floor with escalating % above breakpoint.

How to Use

  1. Enter gross annual sales.
  2. Enter percentage rent rate.
  3. Enter minimum rent floor (optional).
  4. Read gross sales rent.

Frequently Asked Questions

When is % of sales used?

Pop-ups, kiosks, mall carts, food trucks, and short-term licenses. Tenant pays pure share of revenue — no base. LL gets upside but bears downside risk.

What rate?

Carts/kiosks: 10-25% of gross. Pop-ups (30-90 day): 15-30%. Licensed concessions: 8-20%. Lower for high-volume categories, higher for low-volume.

Is a floor common?

Yes — LLs often require a minimum monthly rent to avoid zero-rent months. Tenant pays the greater of floor or % of sales.

What documentation matters here?

Written leases, move-in/move-out inspections with photographs, ledger entries showing every payment and charge, served notices with proof of service, and contemporaneous emails or texts. Courts weigh written evidence heavily; informal understandings rarely stand. Institutional operators run a monthly file audit to catch gaps before they matter. Good paper trails recover most of what's owed.
