Lease Overage Calculator

In commercial real estate, especially in retail leasing, landlords often structure agreements to include not just a base rent, but also a share of tenant sales. This arrangement is known as overage rent or percentage rent.

The Lease Overage Calculator helps both landlords and tenants calculate how much additional rent will be owed once sales surpass a set threshold (known as the breakpoint). By using this tool, businesses can forecast costs, while landlords can estimate potential income from tenant success.

🔎 What Is Lease Overage Rent?

Overage rent is an additional rent payment owed by tenants when their sales exceed a predetermined breakpoint.

Key components include:

• Base Rent – Fixed rent paid regularly.
• Breakpoint – The sales threshold at which overage rent applies.
• Percentage Rent – The percentage of sales above the breakpoint that the tenant must pay.

This structure aligns landlord and tenant interests: tenants pay more only when they perform well, and landlords benefit from tenant success.

📊 Practical Examples

Example 1 – Retail Store with Fixed Breakpoint

• Base Rent: $120,000/year
• Breakpoint: $1,000,000 in sales
• Actual Sales: $1,200,000
• Percentage Rent: 5%

Result:

• Sales Above Breakpoint: $200,000
• Overage Rent: $10,000
• Total Rent: $130,000

👉 The landlord earns extra income while the tenant pays proportionally to their success.

Result:

• Sales Above Breakpoint: $700,000
• Overage Rent: $42,000
• Total Rent: $102,000

👉 High-performing tenants contribute significantly more rent.
