Brick & Mortar vs Online Cost Calculator
Compare monthly operating costs for physical and e-commerce business models
Brick & Mortar Costs (Monthly)
Online Store Costs (Monthly)
How to Use This Tool
Start by selecting your local currency from the dropdown to ensure all cost figures display correctly. Enter your average monthly sales revenue to calculate accurate net margin estimates for both models.
Fill in all applicable monthly cost fields for brick and mortar operations: include rent, utilities, in-store staff wages, POS system fees, physical marketing spend, and business insurance. Leave any non-applicable fields blank to treat them as zero costs.
Next, enter all monthly online store costs: platform subscription fees, hosting/domain costs, payment processing rates (as a percentage), remote staff wages, digital marketing spend, and e-commerce business insurance. Click Calculate Costs to generate a full breakdown.
Use the Reset Form button to clear all inputs and start a new comparison. The Copy Results to Clipboard button lets you save or share the full comparison breakdown.
Formula and Logic
Total Brick & Mortar Monthly Cost = Rent + Utilities + In-Store Staff Wages + POS Fees + Physical Marketing + Business Insurance
Total Online Monthly Cost = Platform Subscription + Hosting + (Monthly Sales × Processing Fee %) + Remote Staff Wages + Digital Marketing + Business Insurance
Estimated Net Margin = ((Monthly Sales - Total Monthly Cost) / Monthly Sales) × 100
Cost Difference = Brick & Mortar Total - Online Total. A positive value means brick and mortar is more expensive; a negative value means online is more expensive.
All processing fees are calculated as a percentage of monthly sales revenue, which reflects real-world payment processor pricing (e.g., Stripe, PayPal, Shopify Payments).
Practical Notes
Keep these trade and business benchmarks in mind when interpreting results:
- Average brick and mortar retail rent ranges from 3-8% of monthly sales revenue for most small businesses.
- Payment processing fees for online stores typically range from 2.4% to 3.5% per transaction, depending on your provider and sales volume.
- Physical marketing costs (flyers, local ads, in-store displays) usually account for 5-10% of monthly revenue for brick and mortar businesses.
- Digital marketing spend for e-commerce stores averages 10-20% of monthly revenue for growth-stage businesses.
- General business insurance for brick and mortar locations is typically 20-50% higher than equivalent online-only coverage due to liability risks.
- Net margins below 15% are considered tight for most retail businesses; margins above 25% are healthy for stable operations.
Why This Tool Is Useful
Small business owners and entrepreneurs often overestimate online store savings or underestimate hidden brick and mortar costs when planning expansion. This tool quantifies both fixed and variable costs (like payment processing fees tied to sales volume) to give a realistic comparison.
It helps e-commerce sellers evaluate if opening a physical pop-up or permanent location fits their budget, and helps brick and mortar owners assess if launching an online store would improve their margins. Sales and marketing teams can use it to allocate budget across channels based on actual cost data.
The detailed breakdown highlights which specific cost categories drive differences between models, so you can adjust spending in high-impact areas first.
Frequently Asked Questions
Should I include one-time setup costs in this calculator?
No, this tool calculates monthly recurring operating costs. One-time expenses like store build-outs, website development, or initial inventory purchases should be amortized over 12-24 months and added to the relevant monthly cost fields if you want to include them.
How do I estimate payment processing fees for my online store?
Check your payment processor's pricing page: most providers charge a percentage of each sale plus a small fixed fee per transaction. For simplicity, use the percentage rate (e.g., 2.9% for standard Shopify Payments) in the processing fee field; the fixed per-transaction fee is negligible for most monthly sales volumes.
What if I have seasonal sales fluctuations?
Run the calculator with your peak monthly sales volume and off-peak volume separately to see how cost differences change with revenue. Variable costs like payment processing fees will increase with higher sales, while fixed costs (rent, subscriptions) stay the same.
Additional Guidance
When comparing models, factor in non-monetary costs not included in this calculator: brick and mortar stores offer in-person customer service and local brand presence, while online stores provide 24/7 global reach and lower overhead. Use this cost data alongside your business goals to make a balanced decision.
If your net margin for either model is negative, reduce high-cost categories first: for brick and mortar, negotiate rent or reduce physical marketing spend. For online stores, audit digital marketing ROI or switch to a lower-cost platform if subscription fees are too high.
Revisit this calculation every 6 months as your business scales: rent may increase, sales volume will change, and you may add staff or marketing channels that shift cost balances between models.
