E-commerce Economics Audit
Personalized Actionable Insights
What Your Result Means
Your ad campaign achieved a ROAS of 5x, yielding a net profit of $5,475 and a profit margin of 36.5%. ROAS below 2.0x indicates unsustainable ad costs or low gross margins.
Mathematically Verified Analysis
Recommended Next Steps
1
Optimize product sourcing: Negotiate unit costs (COGS) with suppliers or manufacture in bulk to improve your gross margins.
2
Raise Average Order Value (AOV): Implement cross-selling, post-purchase bundles, and free shipping thresholds to increase checkout revenue.
3
Improve ad conversions: Focus ad spend on high-converting audiences and test fresh creatives to lower customer acquisition costs.
Mathematical Formula & Equations
Understand the logic under the hood. Here is the formula and exact variable mappings utilized by the E-commerce Profit & RoAS Calculator to compile results.
The Equation
Gross = Price × Orders | Profit = Gross - (COGS + Shipping) × Orders - Ads - Fees%
Gross Revenue is product retail price multiplied by orders count. Net profit subtracts COGS, shipping, ad budgets, and transaction gateway percentages. Return on Ad Spend (RoAS) is gross revenue divided by ad spend.
Variable Definitions
COGS
Direct wholesale cost to purchase or manufacture each individual unit.
Shipping
Average fulfillment and postage packaging cost per unit.
Ads
Total monthly ad campaign budget spent to drive traffic and sales.
Fees%
Merchant transaction fees (Stripe, Paypal) as a percentage of gross revenue.
Methodology & Computational Scope
Our E-commerce Profit & RoAS Calculator integrates corporate accounting protocols (e.g. gross margin calculations, GST taxation equations) to output commercial business ratios with precise step-by-step example steps.

Step-by-Step Example Calculation
See the calculation in action. Below is a step-by-step mathematical example using default parameters to demonstrate how values are processed and generated.
Store Performance Economics Simulation
01Step 1
Product sells for $50, COGS is $15, shipping is $5, and transaction fees are 3.5%. Monthly orders are 300, and ad spend is $3,000.
02Step 2
Gross monthly revenue scales to 300 × $50 = $15,000.
03Step 3
Return on Ad Spend (RoAS) calculates to $15,000 / $3,000 = 5.0x.
04Step 4
Merchant gateway transaction fees are 3.5% of $15,000 = $525.
05Step 5
Total product expenses are ($15 + $5) × 300 = $6,000.
06Step 6
Net monthly profit is $15,000 gross - $6,000 COGS/shipping - $3,000 ads - $525 fees = $5,475 (with a net profit margin of 36.5%!)

Frequently Asked Questions
A "good" RoAS depends heavily on your product profit margins. Generally, a 4:1 RoAS ($4 revenue generated for every $1 spent on ads) is considered highly profitable, whereas a 2:1 RoAS is often the break-even threshold for typical retail margins.
Net profit is calculated by subtracting your product Cost of Goods Sold (COGS), shipping costs, payment processing fees (e.g. 2.9% + $0.30), and advertising spend from your gross retail revenue.
COGS stands for Cost of Goods Sold — the direct cost to manufacture, wholesale buy, or source your product. Keeping COGS low is essential to achieving high net margins and scaling advertising spend.
