Profitability Calculation Methodology

Understanding how we calculate investment potential for container-based self-storage facilities

Beta Version Disclaimer

This profitability calculator is currently in Beta and provided for informational purposes only. The calculations are based on industry benchmarks and market research but should not be considered financial advice.

You must conduct your own due diligence and consult with qualified financial advisors, accountants, and industry experts before making any investment decisions.

Important: For SALE listings, our calculations do not include financing costs such as mortgage interest, loan fees, or down payment requirements. All projections assume full cash purchase.

Overview

Our profitability model evaluates commercial properties for conversion into container-based self-storage facilities. The system generates 5-year financial projections based on site characteristics, local demographics, traffic patterns, and competitive landscape.

We analyze two types of listings differently: LEASE properties (where you rent the land) and SALE properties (where you purchase the land). Each has distinct investment structures and profitability considerations.

Revenue Model

Container-Based Pricing

Revenue is calculated based on 20-foot shipping containers (160 sq ft each) with weekly rental rates determined by market conditions:

Low Competition Areas:£30/week (£130/month)
Average Competition:£35/week (£152/month)
High Competition Areas:£42/week (£182/month)

Regional Pricing Adjustments

Base rates are multiplied by regional factors reflecting local market conditions:

London
1.40× (£180-220/month)
South East
1.15× (£140-160/month)
West Midlands
1.00× (£120-140/month)
North East
0.85× (£105-125/month)

Income-Based Pricing

Affluent areas support premium pricing while lower-income areas require competitive rates:

High Income Areas (Score 80+):+20% premium
Average Income (Score 40-79):Standard pricing
Low Income Areas (Score <20):-15% discount

Insurance Surcharge: All rental rates include a 10% insurance surcharge, reflecting industry standard practice for customer storage insurance.

Cost Structure

One-Time Setup Costs

20ft Containers:£3,000 each
Planning Permission:£5,000
Access Control System:£8,000
CCTV Security:£6,000
Lighting:£4,000
Signage:£2,000
Fencing:£80/meter (scaled)
Groundworks:£0.50/sq ft (scaled)

* Fencing and groundworks costs scale proportionally with site size

Monthly Operating Costs

Site Rent (LEASE only):Annual rent ÷ 12
Insurance:£300 × size factor
Utilities:£200 × size factor
Marketing:£400
Maintenance:£200 × size factor
Business Rates:£500 × size factor

* No staffing costs included - assumes automated facility with remote management

SALE Listings - Finance Costs Not Included: For properties purchased outright, our calculations assume full cash payment. Mortgage interest, loan origination fees, and other financing costs are not factored into the profitability projections.

Occupancy Ramp-Up Model

Occupancy increases gradually over time based on competitive landscape. Markets with fewer competitors achieve higher occupancy rates faster:

Competition LevelMonths to MaxTarget Occupancy
Low Competition (Score 80-100)10 months85%
Medium Competition (Score 40-79)14 months80%
High Competition (Score 0-39)20 months75%

Year 1: Ramping from 0% to partial occupancy (average 35-40%)
Year 2: Continuing ramp-up if needed
Year 3-5: Steady state at target occupancy with 3% annual price increases

Profitability Score (0-100)

Our profitability score combines three key financial metrics to provide an overall investment rating:

1. ROI Score (0-40 points)

Measures 5-year return on investment relative to total setup costs.

• 200% ROI = 40 points
• 100% ROI = 20 points
• Formula: min(40, year5ROI ÷ 5)

2. Breakeven Score (0-30 points)

Rewards faster path to profitability. Shorter breakeven = higher score.

• 12 months = 30 points
• 24 months = 12 points
• 36+ months = 0 points
• Formula: max(0, 30 - (months - 12) × 1.5)

3. Profit Margin Score (0-30 points)

Evaluates operational efficiency through Year 5 net profit margin.

• 60% margin = 30 points
• 30% margin = 15 points
• Formula: min(30, (netProfit ÷ revenue) × 50)

LEASE vs SALE Listings

LEASE Listings

  • Lower upfront investment (setup costs only)
  • Annual rent included in monthly operating costs
  • Faster breakeven due to lower initial capital
  • No equity building or property appreciation
  • Ongoing rent expense reduces long-term profit

SALE Listings

  • Build equity and benefit from property appreciation
  • No ongoing rent expense (higher long-term profit)
  • Full control over property and exit strategy
  • Higher upfront investment (land + setup costs)
  • Financing costs NOT included in our calculations
