Thinking about opening a restaurant? Restaurant lease costs should be tested against realistic sales before you commit to a location. Convert the annual price per square foot into monthly rent, add NNN charges, and calculate the revenue needed to carry that obligation.  One of the biggest mistakes restaurant owners make is getting a lease that their restaurant sales cannot support. A beautiful space can become an expensive mistake when the sales do not support the lease.

It can feel like landlords are winning when rent payments take priority over your paycheck. Rent remains due during your strongest month and your slowest month. Your decision should account for both.

Restaurant Broker Tip: The yearly rent should be no higher than 10% of gross net sales. The best restaurants have 5%- 8% of gross net sales. Once the percentage is higher than 10%, it increases the chances of a restaurant closing.

How do you calculate restaurant lease costs

An advertised $48 per square foot usually refers to the base rent and does not include Common Area Maintenance (CAMS) expense.  Confirm the quote’s units and whether it includes operating expenses. For a 2,000-square-foot restaurant, the calculation is:

$48 × 2,000 square feet ÷ 12 months = $8,000 in monthly base rent.

Under a triple net, or NNN, structure, tenants generally pay additional charges for property taxes, building insurance, and common area maintenance. If those charges are $12 per square foot annually, add $2,000 monthly. Your combined base rent and NNN would be $10,000 per month, or $120,000 annually, before utilities and other operating costs.

Here is how different hypothetical base rates change the obligation for the same 2,000-square-foot space. These are calculation examples, not market quotes.

Annual base rate	Monthly base rent	Monthly sales at 10%*
$40/SF	$6,667	$66,667
$48/SF	$8,000	$80,000
$50/SF	$8,333	$83,333
$60/SF	$10,000	$100,000

How much should your restaurant sell to support the rent

For an initial affordability screen, EATS Broker recommends testing whether base rent plus NNN can stay at or below 10% of gross sales. Treat that as a ceiling to investigate, not a spending target or a promise of profit. Many concepts need a lower occupancy ratio to leave enough room for food, labor, debt service, and owner income.

The National Restaurant Association reported median occupancy costs of 5.7% of sales for full-service respondents and 5.2% for limited-service respondents in 2024. Those national survey results provide context, not a required operating standard for your restaurant.

Use this formula: Monthly sales target = (monthly base rent + monthly NNN) ÷ 0.10.

At $10,000 per month, you need $100,000 in monthly gross sales to reach that 10% screen. At a $25 average check, that means 4,000 checks per month, or approximately 134 daily if you open 30 days. A check may cover more than one guest; use consistent sales and transaction definition in your model.

Then test a slower month. At $75,000 in sales, the same $10,000 obligation consumes 13.3% of revenue. The extra pressure must come out of cash that could otherwise cover payroll, suppliers, repairs, or your income. Meeting the rent ratio alone does not establish your break-even point.

Does a second-generation restaurant space make the lease affordable

A second-generation restaurant space was previously used as a restaurant and may have valuable infrastructure such as a hood, grease interceptor, plumbing, or walk-in cooler. Reusing suitable systems can reduce opening costs. Confirm their condition, capacity, ownership, and compatibility with your concept before assigning value to them.

Whether you are searching Plano, Frisco, or Uptown Dallas, or considering Montrose, the Heights, or Rice Village in Houston, compare individual properties using the full monthly obligation. A busy address does not prove that your menu, average check, parking needs, or operating hours will generate enough revenue there.

Buying an existing restaurant also requires a lease review. A low business asking price may come with rising rent, limited remaining term, or uncertain renewal options. Verify landlord approval requirements and the terms available to you before committing to the acquisition. Build-out savings should not distract you from the obligation you will carry after closing.

What should you negotiate before signing a restaurant lease

Ask for the proposed lease, current NNN budget, and available expense reconciliation history early. Compare today’s payment with the scheduled increases over the term. Your financial model should include opening delays, realistic ramp-up sales, and adequate working capital.

The negotiation should address more than the starting rent:

• Rent commencement and concessions that account for delivery condition, improvements, and approvals.
• NNN definitions, reconciliation procedures, exclusions, and any negotiable expense caps.
• Responsibility for HVAC, roof, plumbing, grease systems, and equipment repairs.
• Remaining term, renewal options, permitted use, signage, parking, and assignment requirements.
• Personal guarantees and any negotiated limits or release provisions.

Have your broker evaluate the business terms and coordinate with your attorney on the lease language. If the required sales volume depends on an immediate perfect opening, revisit the rent, the space size, or the location before signing.

Why EATS Broker offers buyer representation

This is one reason EATS Broker offers buyer representation: to help protect restaurant buyers and prospective tenants from costly lease mistakes and give them an advocate when negotiating their interests. Finding an appealing listing is only one part of the decision. Understanding whether the business and lease fit your financial capacity is just as important.

Our representation can help you evaluate opportunities, identify lease concerns, assess the sales needed to support occupancy costs, and negotiate business terms within the agreed scope of the engagement. When purchasing an operating restaurant, that includes considering how the lease affects the acquisition and your future exit.

If you have additional questions or inquiries about buyer representation, contact EATS Broker to discuss your goals and the support available for your restaurant purchase or leasing search.

Does NNN include every expense

No. Review the lease and budget separately for utilities, maintenance obligations, percentage rent, insurance you must carry, and other charges. A quoted NNN estimate may change.

Can you negotiate a restaurant lease assignment

Potentially. The existing lease, landlord consent requirements, and parties’ willingness determine what can change. Identify the terms you need before committing to the business purchase.

Is rent at 10 percent of sales automatically affordable

No. Food and labor costs, royalties, financing, and other expenses can make a restaurant unprofitable even at that ratio. Test the complete operation and a downside sales scenario.
