Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Sales Per Sq Ft = Total Retail Sales / Total Store Selling Square Footage

Step-by-Step Mathematical Derivation

1
Selling Floor Area

Selling Space = 3,200 total sq ft × 75.0% = 2,400 sq ft customer showroom area.

2
Sales Per Selling Square Foot

Sales Per Selling Sq Ft = $1,450,000 / 2,400 sq ft = $604.17 per sq ft.

3
Sales Per Gross Footprint

Sales Per Gross Sq Ft = $1,450,000 / 3,200 sq ft = $453.13 per sq ft.

4
Occupancy Cost Burden

Rent to Sales Ratio = ($115,000 / $1,450,000) × 100 = 7.93% (well within healthy retail threshold of < 10%).
