Business rent affordability guide
How Much Rent Can Your Business Afford?
A rent-to-revenue ratio shows how much of your business revenue goes toward rent, but it does not determine whether a lease is affordable.
A useful lease budget also considers your margins, other fixed costs, additional occupancy expenses, cash flow, and the amount of space your business actually needs.

Calculator disclaimer: This calculator is a budgeting tool, not financial, accounting, tax, or legal advice. A sustainable occupancy cost depends on your business’s complete financial circumstances.
Use the calculator above as a screening tool before comparing commercial properties.
Rent-to-Revenue Ratio
Rent ÷ Revenue × 100 = Rent-to-Revenue Ratio
Example
A business with $300,000 in annual revenue and $24,000 in annual rent has an 8% rent-to-revenue ratio.
$24,000 ÷ $300,000 × 100 = 8%
That calculation tells you that eight cents of every revenue dollar goes toward rent. It does not tell you whether 8% is affordable for your particular business.
Your margins, payroll, debt, insurance, utilities, taxes, other operating expenses, and cash requirements still matter.
What Is a Rent-to-Revenue Ratio?
A rent-to-revenue ratio compares the cost of renting business space with the revenue the business generates.
Rent-to-Revenue Ratio = Rent Expense ÷ Revenue × 100
Use matching periods for both numbers. Annual rent should be divided by annual revenue. Monthly rent should be divided by monthly revenue.
The ratio is useful because commercial rent is generally a fixed business expense. The U.S. Small Business Administration includes rental lease payments among fixed costs businesses should consider when analyzing their break-even point.
The limitation is equally important: two businesses with the same ratio can have very different financial circumstances.
A professional service firm, retailer, restaurant, medical practice, and technology company can have very different payroll, inventory, equipment, insurance, and operating costs.
For that reason, your rent-to-revenue ratio is a screening metric, not an automatic pass-or-fail test.
Is There a Good Rent-to-Revenue Percentage?
There is no single rent-to-revenue percentage that establishes whether a commercial lease is affordable for every business.
Industry, margins, location, business model, lease structure, and included expenses all affect the answer.
Published industry benchmarks can provide context, but they should be compared with businesses similar to yours rather than treated as universal limits.
A stronger analysis asks three questions:
- What percentage of revenue would go toward the proposed rent?
- What other occupancy expenses would the lease require?
- Can the business still cover payroll, operating costs, debt, taxes, reinvestment, and profit after paying for the space?
If you need an industry benchmark, compare your business with current data for your specific industry and market rather than relying on a single percentage intended for all businesses.
Calculate Total Occupancy Cost, Not Just Base Rent
Base rent may not represent your full cost of occupying commercial space.
Depending on the lease, additional expenses can include:
- Common-area maintenance charges
- Utilities
- Property-tax pass-throughs
- Insurance obligations
- Repairs or maintenance responsibilities
- Parking charges
- Build-out expenses
- Communications and data service
- Scheduled rent increases
The exact allocation depends on the lease.
That distinction matters when comparing properties. A space with a lower advertised base rent can cost more overall if the tenant is responsible for additional operating expenses.
For budget planning, calculate both numbers:
Base Rent Ratio = Base Rent ÷ Revenue × 100
Occupancy Cost Ratio = Total Occupancy Costs ÷ Revenue × 100
The second calculation gives you a more complete view of how the space affects your operating budget.
Work Backward From Your Business Budget
A lease should fit into the economics of your business, not the other way around.
Use the same discipline when evaluating office rent.
1. Estimate realistic revenue
Use actual recent revenue for an established business.
For a new business or expansion, test more than one revenue scenario rather than relying only on the most optimistic forecast.
2. Identify existing fixed costs
Include expenses that remain relatively stable regardless of sales volume.
Examples may include salaries, insurance, debt payments, equipment obligations, and existing lease commitments.
3. Estimate the complete occupancy cost
Include the proposed base rent plus any additional expenses the lease assigns to the tenant.
4. Calculate the rent-to-revenue ratio
Divide rent by revenue using matching monthly or annual periods.
5. Calculate the total occupancy ratio
Repeat the calculation using all anticipated occupancy expenses rather than base rent alone.
6. Test the result against your complete budget
Determine what remains after occupancy costs for payroll, supplies, insurance, taxes, debt service, marketing, technology, reinvestment, and profit.
A percentage that works comfortably for one company can be too high for another company with thinner margins or higher operating expenses.
How Commercial Rent Per Square Foot Affects Your Budget
Commercial office rent is commonly evaluated using both total rent and the amount of space being leased.
If a quoted rate is expressed annually per square foot, the basic calculation is:
Annual Rental Cost = Annual Rate per Square Foot × Rentable Square Feet
Then:
Monthly Rental Cost = Annual Rental Cost ÷ 12
Before comparing two properties, confirm what the quoted rate includes.
A rate that includes some operating expenses cannot be compared directly with a rate that requires the tenant to pay those expenses separately.
The lease structure and total occupancy cost matter more than the advertised rate alone.
Rentable Space Is Not Always the Same as the Space Inside Your Suite
Office tenants should understand what area their rent is based on.
The Building Owners and Managers Association’s current Office Standard, ANSI/BOMA Z65.1-2024, establishes standardized methods for measuring office buildings and calculating rentable area.
In a multi-tenant building, rentable area may account for more than the space located exclusively inside your office.
That makes two questions important when evaluating a suite:
How much space can my business actually use?
How much space does the lease use to calculate rent?
Ask how the property measures the suite and what shared building areas are included before comparing price-per-square-foot figures between buildings.
If you are still determining how much space you need, Atrium Properties’ Clifton Park Office Planning Guide walks through headcount, layout, meeting space, circulation, and growth considerations.
Example: Comparing Two Office Options
Suppose your business is considering two offices.
Option A
- Lower base rent
- Additional operating expenses billed separately
- More space than your business currently needs
Option B
- Higher quoted base rent
- More expenses included
- Smaller footprint that better matches your actual requirements
Looking only at advertised rent could make Option A appear less expensive.
A better comparison calculates the total annual occupancy cost of each option and then measures that amount against revenue.
The right question is not simply:
Which office has the lowest rent?
It is:
Which office gives the business the space it needs at a total cost the business can support?
Questions to Ask Before Signing a Commercial Lease
Use this checklist before committing to a space:
- What exactly is included in the quoted rent?
- Which operating expenses are paid separately?
- How is the rentable area measured?
- Are utilities included or separately metered?
- Are common-area charges fixed or variable?
- Does the lease include scheduled rent increases?
- Who pays for alterations or build-out?
- What costs are due before move-in?
- What renewal options are available?
- What happens if the business needs more or less space later?
Review the actual lease terms and your complete business budget before making a financial commitment.

Frequently Asked Questions
What is the rent-to-revenue ratio?
The rent-to-revenue ratio is rent expense divided by revenue, expressed as a percentage. Use rent and revenue from the same monthly or annual period. The result shows how much revenue is being allocated to rent, but it does not measure profitability by itself.
How do I calculate rent as a percentage of revenue?
Divide rent by revenue and multiply the result by 100. For example, $24,000 in annual rent divided by $300,000 in annual revenue equals 0.08, or 8%. Use the same time period for both figures.
What percentage of revenue should go toward commercial rent?
There is no universal percentage appropriate for every business. The sustainable amount depends on your industry, margins, payroll, operating costs, lease structure, location, and other obligations. Industry-specific benchmarks can provide context, but your full business budget should determine affordability.
Should CAM charges be included in a rent-to-revenue calculation?
Calculate base rent separately first. Then calculate a second ratio using all occupancy expenses the lease requires you to pay. This gives you both the base-rent ratio and a broader occupancy-cost ratio for comparing properties.
How do I compare commercial rents quoted per square foot?
Multiply the annual rate per square foot by the rentable square footage to estimate annual base rent, then divide by 12 for a monthly figure. Confirm what the rate includes before comparing properties because lease structures can allocate operating expenses differently.
What is the difference between usable and rentable office space?
Usable space generally refers to the area occupied directly by the tenant. Rentable-area calculations may also allocate portions of shared building areas. Ask how each property measures rentable area before comparing price-per-square-foot figures.
Know Your Number Before You Tour
A rent-to-revenue ratio gives you one useful number. A sound leasing decision requires the complete picture.
Calculate the ratio, identify the full occupancy cost, determine how much space your business actually needs, and test those costs against the rest of your operating budget.
When you have those numbers, Atrium Properties can help you compare office options in Clifton Park that fit your space requirements and budget.
