Why is my Net Margin lower than my Gross Margin?

Gross Margin only considers product manufacturing cost (COGS). Net Margin accounts for all additional operational overhead including shipping labels, packaging, payment processor fees (Stripe/PayPal), and advertising expenses.

What is considered a good profit margin for direct-to-consumer (DTC) stores?

In DTC e-commerce, a Gross Margin above 65% is ideal because it leaves sufficient room (30-40%) for paid acquisition channels like Meta and Google Ads while retaining a 15-20% Net Profit margin.

How do gateway fees (e.g. 2.9% + $0.30) impact low-ticket items?

On low-priced products (e.g. $10), a fixed $0.30 fee represents an extra 3% fee on top of percentage fees, eating directly into net margins. Bundling products or increasing average order value (AOV) protects margins.

1How to Use E-Commerce Profit Margin & ROAS Calculator

Profitable e-commerce and retail operations depend on healthy unit economics. Confusing Markup with Margin or underestimating transaction fees and advertising customer acquisition costs (CAC) is the most frequent cause of business failure.

Step 1.Select your preferred currency (₹ INR, $ USD, or € EUR).
Step 2.Enter your Cost of Goods Sold (COGS) and Retail Selling Price.
Step 3.Enter per-unit Shipping & Packaging costs and Platform/Gateway transaction fees (e.g. 2-3%).
Step 4.Enter target or average Ad Spend per unit sold (CAC).
Step 5.Review your Gross Profit Margin, Net Margin %, and your critical Break-Even ROAS metric.

2Formulas, Methodology & Key Features

Core E-Commerce Financial Formulas

These fundamental equations govern retail profitability:

Gross Profit = Selling Price - COGS Gross Margin % = (Gross Profit / Selling Price) × 100 Markup % = (Gross Profit / COGS) × 100 Net Profit = Selling Price - (COGS + Shipping + Fees + Ad Spend) Net Margin % = (Net Profit / Selling Price) × 100 Break-Even ROAS = Selling Price / (Selling Price - COGS - Shipping - Fees)

The Critical Difference Between Margin and Markup

Margin is profit expressed as a percentage of Selling Price. Markup is profit expressed as a percentage of Cost. A 50% markup on a $100 product ($50 profit on $150 sale) equals a 33.3% margin, not a 50% margin.

Common questions answered about E-Commerce Profit Margin & ROAS Calculator.

Break-Even ROAS (Return on Ad Spend) is the minimum multiple of revenue your marketing campaigns must generate for each ad dollar spent without losing money. For example, a 2.0x break-even ROAS means every $100 in advertising must generate at least $200 in gross revenue to break even.
