Percentage Rent Calculator

Enter your gross sales, lease breakpoint, percentage rate, and landlord billed amount to verify the right percentage rent and catch retail overpayments quickly.

Why this matters: Percentage rent errors often look small on a single statement, but they compound across high-volume retail periods. A bad breakpoint or inflated gross sales definition can shift thousands of dollars in rent.

Percentage rent errors usually come from one of three places: the breakpoint, the gross sales definition, or the billed amount itself. Use this calculator to confirm the math first, then trace the source of the variance in your lease and sales backup.

Frequently Asked Questions

How do you calculate percentage rent?
Percentage rent equals the percentage rate multiplied by gross sales above the lease breakpoint. If sales do not exceed the breakpoint, no percentage rent is owed for that period.
What is the breakpoint in a percentage rent lease?
The breakpoint is the sales threshold above which percentage rent starts. Some leases use a natural breakpoint based on base rent and rate, while others use an artificial negotiated breakpoint.
What causes a percentage rent overpayment?
The most common causes are a breakpoint set too low, a percentage rate applied incorrectly, or gross sales definitions that include excluded categories such as sales tax, returns, or employee discounts.
What if my landlord billed more than the calculator shows?
Compare the lease breakpoint, the gross sales definition, and the rate in your lease against what appears on the landlord statement. If the billed amount is higher than the correct amount, document the variance and pull your backup records before sending a dispute letter draft.
What should I read after using this calculator?
Start with the Percentage Rent Audit Guide for the full audit workflow, then review Percentage Rent Breakpoint Errors if the mismatch comes from the breakpoint itself.

Errors in the breakpoint definition or gross sales inclusion rules create overcharges that compound annually.

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.
