Percentage Rent & Breakpoint Calculator
Enter the base rent, sales, exclusions, percentage rate, and breakpoint method to estimate percentage rent and total annual rent. The result also shows the occupancy cost ratio implied by the lease rent.

Assumes one annual measurement period and applies one percentage rate.
The negotiated breakpoint input is ignored because natural breakpoint is selected.
How to use this calculator
- Choose how the minimum base rent is quoted in the lease.
- Enter rentable area, annual gross sales, and any sales excluded by the lease definition.
- Enter the percentage rent rate and choose a natural or negotiated breakpoint.
- Read the percentage rent, total annual rent, effective rent per square foot, and occupancy cost.
How percentage rent is calculated
Percentage rent is additional rent tied to store sales. Most retail leases that use it start with minimum base rent, then apply a stated percentage only after adjusted sales pass a breakpoint. The breakpoint can be natural, meaning it is implied by the base rent and percentage rate, or artificial, meaning the lease states a negotiated sales amount.
This calculator first converts the entered base rent into annual base rent. If rent is quoted per square foot, it multiplies the rent by rentable area. If rent is quoted monthly, it multiplies by 12. If rent is already annual, it uses that amount directly.
The main formula is:
annual base rent = base rent amount x area when rent is quoted annually per square foot.
adjusted sales = max(0, gross sales - excluded sales)
natural breakpoint = annual base rent / percentage rate
percentage rent = max(0, adjusted sales - applied breakpoint) x percentage rate
total annual rent = annual base rent + percentage rent
occupancy cost = total annual rent / adjusted sales
What moves the result most
The percentage rate and breakpoint decide how much sales growth turns into rent. A higher rate raises percentage rent once the breakpoint is crossed. A higher breakpoint delays that rent. Base rent also matters twice in a natural breakpoint: it raises the fixed rent owed and raises the sales level required before percentage rent starts.
Sales exclusions can be just as important as the stated sales number. Returns, employee discounts, delivery sales, taxes collected from customers, wholesale transactions, and online sales may be included or excluded depending on the lease language. This tool treats exclusions as one annual amount because the lease definition controls the actual adjustment.
Natural versus negotiated breakpoint
A natural breakpoint is the sales level at which percentage rent equals base rent divided by the percentage rate. For example, $75,000 of annual base rent at 6% produces a natural breakpoint of $1,250,000. A negotiated breakpoint can be higher or lower than that amount. If it is lower, percentage rent starts sooner; if it is higher, the tenant needs more sales before additional rent is due.
What this calculator leaves out
The estimate uses one annual period, one rate, and one breakpoint. It does not model tiered percentage rent, breakpoint resets, caps, floors, co-tenancy clauses, partial-year proration, audit adjustments, or separate occupancy expenses such as CAM charges, property taxes, insurance, utilities, or sales taxes.
Worked example
Suppose a store leases 2,500 square feet at $30 per square foot per year, reports $1,250,000 of annual gross sales, excludes $50,000 of sales, and pays 6% percentage rent over a natural breakpoint. Annual base rent is $30 x 2,500, or $75,000. Adjusted gross sales are $1,200,000.
The natural breakpoint is $75,000 / 6%, or $1,250,000. Because adjusted sales are $50,000 below that breakpoint, percentage rent is $0. Total annual rent remains $75,000, effective monthly rent is $6,250, effective annual rent is $30 per square foot, and rent occupancy cost is 6.25% of adjusted sales.
Common questions
What is percentage rent in a retail lease?
Percentage rent is rent based on a tenant's sales, usually in addition to a fixed minimum base rent. The lease states the sales definition, exclusions, rate, measurement period, and breakpoint. The tenant generally pays percentage rent only on sales above that breakpoint.
How is a natural breakpoint calculated?
A natural breakpoint equals annual base rent divided by the percentage rent rate expressed as a decimal. If annual base rent is $75,000 and the rate is 6%, the natural breakpoint is $1,250,000. At that sales level, 6% of sales equals the base rent.
What is the difference between a natural and artificial breakpoint?
A natural breakpoint is implied by the base rent and percentage rate. An artificial, or negotiated, breakpoint is written into the lease as a specific sales amount. It can be higher or lower than the natural breakpoint, changing when percentage rent begins.
Which sales are commonly excluded from percentage rent?
Common exclusions can include returns, discounts, employee purchases, sales taxes collected from customers, certain online sales, delivery fees, or wholesale transactions. The exact list depends on the lease. Use the excluded sales input for amounts the lease removes from gross sales before applying the breakpoint.
Is percentage rent charged on all sales or only sales above the breakpoint?
In the common breakpoint structure, percentage rent is charged only on adjusted sales above the applied breakpoint. If the negotiated breakpoint is zero, the percentage rate applies to all adjusted sales. Some leases use tiered rates or other structures that this calculator does not model.
How do base rent and percentage rent affect occupancy cost?
Rent occupancy cost is total annual rent divided by adjusted gross sales. Base rent sets the fixed part of that ratio, while percentage rent increases it after sales pass the breakpoint. Other occupancy expenses can make the total occupancy cost higher than the rent-only percentage shown here.
