Understanding the Input Fields
Let's break down each input field in the calculator and what they mean for your investment:
Property Cost
What it is: The total purchase price of the storage facility.
Why it matters: This is your initial investment and forms the basis for calculating returns.
Example: $500,000 for a facility with 50 units
Formula Connection
Property Cost is used to calculate: Cap Rate, Cash on Cash ROI, and Total ROI
Number of Units
What it is: The total number of rentable storage units in the facility.
Why it matters: Determines your maximum revenue potential.
Example: 50 units of various sizes (5x5, 10x10, 10x20)
Pro Tip
Consider the mix of unit sizes. A variety of sizes can help maintain higher occupancy rates.
Average Monthly Rent
What it is: The average monthly rental price per unit.
Why it matters: Directly impacts your revenue. Higher rents mean higher income.
Example: $100 per month average across all unit sizes
Revenue Calculation
Monthly Revenue = Number of Units × Occupancy Rate × Average Monthly Rent
50 units × 85% occupancy × $100 = $4,250 monthly revenue
Occupancy Rate (%)
What it is: The percentage of units that are rented at any given time.
Why it matters: Higher occupancy means more consistent revenue.
Example: 85% occupancy means 42-43 of 50 units are rented
Industry Standard
Well-managed storage facilities typically maintain 85-90% occupancy. Rates below 80% may indicate management or marketing issues.
Monthly Operating Expenses
What it is: All costs to operate the facility excluding debt payments.
Why it matters: Lower expenses mean higher profit margins.
Example: $5,000 per month for utilities, insurance, management, maintenance
Includes: Property taxes, insurance, utilities, payroll, marketing, repairs, management fees
Loan Amount
What it is: The amount financed through a mortgage or loan.
Why it matters: Determines your monthly debt service and cash investment.
Example: $400,000 loan on a $500,000 property
Down Payment
Down Payment = Property Cost - Loan Amount
$500,000 - $400,000 = $100,000 down payment
Interest Rate (%)
What it is: The annual interest rate on your loan.
Why it matters: Lower rates reduce your debt service and increase cash flow.
Example: 5.5% annual interest rate
Rate Shopping
Even a 0.5% difference in interest rates can significantly impact your long-term profitability. Always shop for the best rates.
Loan Term (Years)
What it is: The length of the loan in years.
Why it matters: Longer terms mean lower monthly payments but more total interest paid.
Example: 30-year loan term
Annual Appreciation (%)
What it is: The expected annual increase in property value.
Why it matters: Adds to your total return through equity buildup.
Example: 3% annual appreciation
Real Estate Appreciation
Storage facilities typically appreciate 2-4% annually, though this varies by market and property condition.
Key Calculations and Formulas
Annual Revenue Formula
Annual Revenue = (Number of Units × Occupancy Rate × Average Monthly Rent) × 12
Example: (50 × 0.85 × $100) × 12 = $51,000
Net Operating Income (NOI)
NOI = Annual Revenue - Annual Operating Expenses
Example: $51,000 - ($5,000 × 12) = $51,000 - $60,000 = -$9,000
Note: A negative NOI indicates the property isn't covering its operating expenses at current rates and occupancy.
Cap Rate Formula
Cap Rate = (Net Operating Income ÷ Property Cost) × 100
Example: ($30,000 ÷ $500,000) × 100 = 6%
Cash on Cash ROI
Cash on Cash ROI = (Annual Cash Flow ÷ Cash Invested) × 100
Example: ($12,000 ÷ $100,000) × 100 = 12%
Mortgage Payment Calculation
Monthly Payment = P × [r(1+r)^n] ÷ [(1+r)^n - 1]
Where: P = Loan Amount, r = Monthly Interest Rate, n = Total Payments
Understanding the Results
Annual Revenue
Your total income from rented units before expenses. This shows the revenue potential of your facility.
Net Operating Income
Revenue minus operating expenses. This indicates how efficiently the property operates before financing costs.
Cash Flow
Your monthly profit after all expenses and loan payments. Positive cash flow is essential for a sustainable investment.
Cap Rate
The return on investment if you paid cash for the property. Higher cap rates generally mean higher returns but may indicate higher risk.
Cash on Cash ROI
Your return on the actual cash you invested. This accounts for leverage and shows how effectively your money is working.
Total ROI (5 Years)
Your estimated total return including cash flow and property appreciation over 5 years.
Frequently Asked Questions (FAQ)
Cap rates typically range from 5% to 9% for storage facilities. Higher cap rates often come with higher risk or properties needing improvement. Prime locations with stable occupancy usually command lower cap rates (5-7%), while secondary markets might see 7-9%.
The projections are estimates based on your inputs and standard industry growth assumptions (3% annual rent increase, 2% expense growth). Actual results will vary based on market conditions, management effectiveness, and economic factors.
Most investors target 8-12% cash-on-cash return for storage facilities. Returns below 6% may not adequately compensate for the risk and management effort involved.
Occupancy rate directly impacts revenue. A 10% drop in occupancy (from 85% to 75%) typically reduces revenue by about 12%. Maintaining high occupancy is crucial for profitability.
Include: property taxes, insurance, utilities, payroll, management fees, marketing, repairs/maintenance, office supplies, and professional services. Don't include debt service or capital improvements.
Very important. A diverse mix of unit sizes (small, medium, large) helps maintain occupancy by appealing to different customer needs. Facilities with only one size may struggle with occupancy fluctuations.
Most lenders offer 70-80% LTV for storage facilities. This means you'll typically need 20-30% down payment. Stronger properties with proven cash flow may qualify for higher LTV ratios.
Storage demand often peaks during summer months (moving season) and may dip in winter. Factor this into your occupancy rate estimates - use annual averages rather than peak or trough numbers.
Common overlooked costs include: property tax reassessments after purchase, insurance premium increases, regulatory compliance costs, security system maintenance, and unexpected repairs to doors, roofs, or pavement.
The 3% default is a reasonable historical average, but actual appreciation varies by market, property condition, and economic conditions. Conservative investors use 2%, while optimistic projections might use 4%.
Break-even occupancy is when NOI equals debt service. For our example: $60,000 annual expenses + $27,000 debt service = $87,000 needed revenue. With 50 units at $100/month, that's 72 units rented annually or about 60% occupancy.
Storage facilities are typically valued based on NOI and cap rate: Value = NOI ÷ Cap Rate. A facility with $50,000 NOI at a 7% cap rate would be valued at approximately $714,000.
Good storage investments typically have: strong location with high visibility, diverse unit mix, modern security features, well-maintained facilities, stable or growing occupancy, and manageable competition in the area.
