Formula and Logic
This tool uses standard small business operating cost calculation methods tailored to dark store and quick-commerce operations:
- Total Monthly Operating Cost = Rent + Labor Costs + Inventory Restocking + Logistics & Delivery + Utilities & Maintenance + Marketing & SaaS + Other Expenses
- Labor Costs = (Full-Time Staff Count × Full-Time Average Monthly Salary) + (Part-Time Staff Count × Part-Time Average Monthly Salary)
- Cost Per Area = Total Monthly Operating Cost ÷ Store Size (adjusted for square feet or square meters)
- Cost Per Order = Total Monthly Operating Cost ÷ Average Monthly Order Volume (if order volume is provided)
- Annual Operating Cost Projection = Total Monthly Operating Cost × 12
- Category Percentages = (Category Cost ÷ Total Monthly Operating Cost) × 100
Practical Notes
Dark stores operate on thin margins compared to traditional retail, so accurate cost tracking is critical for profitability. Keep these industry-specific tips in mind:
- Typical dark store rent ranges from $15 to $45 per square foot per year in suburban markets, and up to $80+ per square foot in prime urban areas.
- Labor costs usually account for 25-40% of total operating expenses for dark stores with 5-10 staff members.
- Logistics and delivery costs can spike during peak hours or promotional periods; use your average monthly spend for steady-state estimates.
- Include hidden costs like payment gateway fees, insurance, and security in your Other Expenses category.
- Compare your cost per order to your average order value (AOV) to ensure you maintain a healthy contribution margin.

Frequently Asked Questions
What is a dark store?
A dark store is a retail warehouse or fulfillment center dedicated to online order fulfillment, with no customer-facing retail space. They are commonly used by quick-commerce companies to offer 30-minute to 2-hour delivery windows for groceries, essentials, and other goods.
How do I estimate part-time staff costs for variable hours?
Use the average monthly earnings for part-time staff based on your historical payroll data. If you're planning a new store, research local part-time wage rates for warehouse and fulfillment roles, and multiply by the average number of shifts per month.
Should I include one-time setup costs in this estimate?
No, this tool calculates recurring monthly operating costs. One-time expenses like racking, initial inventory, signage, and renovation costs should be tracked separately as capital expenditures (CapEx) rather than operating expenses (OpEx).
Additional Guidance
For the most accurate results, update your inputs monthly as expenses fluctuate. Pair this tool with a revenue tracker to calculate net profit margins for your dark store. If your cost per order exceeds 60% of your average order value, review your logistics and labor costs first, as these are the most common areas for overspending in quick-commerce operations.
