How Percentage Rent Works

Base Rent

The guaranteed minimum rent amount, paid regardless of tenant sales performance.

Breakpoint

The sales threshold that triggers additional percentage rent obligations.

Percentage Rent

Additional rent calculated as a percentage of sales exceeding the breakpoint.

Percentage Rent Formula

  • Excess Sales = max(0, Gross Sales − Breakpoint)
  • Percentage Rent = Excess Sales × Percentage Rate
  • Total Rent = Base Rent + Percentage Rent

Example:

  • Base Rent = $5,000/month

  • Gross Sales = $120,000/month

  • Breakpoint = $100,000

  • Percentage Rate = 5%

  • Excess Sales = 120,000 − 100,000 = $20,000

  • Percentage Rent = 20,000 × 0.05 = $1,000

  • Total Rent = 5,000 + 1,000 = $6,000

Percentage rent adds a variable rent component based on sales performance. If gross sales exceed the breakpoint, a percentage of the excess is charged in addition to the fixed base rent.

How this percentage rent calculator works

The calculator compares gross sales to the breakpoint, computes excess sales (if any), multiplies by the agreed percentage rate to get percentage rent, and adds that to base rent for a clear total. Use it to model lease offers, forecast rent under different sales scenarios, and plan monthly cash flow.

When to use this percentage rent calculator

  • During lease negotiations to test different breakpoints and rates
  • Budgeting annual rent under seasonal sales patterns
  • Comparing base-heavy vs percentage-heavy lease structures
  • Validating natural vs negotiated (artificial) breakpoints
  • Planning rent accruals and reconciliations for accounting

Typical Percentage Rent Terms

Benchmarks vary by asset type and market, but these ranges are common:

Retail percentage rate

5%–7% of sales over breakpoint

Restaurant percentage rate

6%–10% of sales over breakpoint

Natural breakpoint (rule of thumb)

Base Rent ÷ Percentage Rate

Reconciliation

monthly accrual with annual true-up in many leases

Use your historical sales and traffic forecasts to set realistic breakpoints and negotiate fair percentage rates.

Frequently Asked Questions

What is percentage rent?

A rent structure where tenants pay base rent plus a percentage of sales over an agreed breakpoint.

What's a natural breakpoint?

A breakpoint implied by Base Rent ÷ Percentage Rate; many leases instead use a negotiated (artificial) breakpoint.

Is percentage rent calculated monthly or annually?

Depends on the lease; many track monthly and reconcile annually. Set the calculator period to match your lease.

What if sales don't exceed the breakpoint?

Only base rent is due; percentage rent = $0.

Are returns or taxes excluded from gross sales?

Leases usually define "gross sales" precisely—returns may be excluded; sales tax is usually excluded. Check your lease.

Can there be multiple rates or tiers?

Yes, some leases have tiered percentage rates at higher sales bands. Model each tier and sum.

Does this include CAM/NNN?

No. This calculator covers base + percentage rent. Add CAM/NNN separately if your lease requires them.

How do I annualize monthly results?

Multiply monthly totals by 12 (or use the annual mode in the calculator).
