Introduction
Running an online store is not just about selling products — it’s about selling them profitably. Many new e-commerce owners set prices without truly understanding their profit margin, which can lead to hidden losses. In this post, I’ll explain what profit margin is, how to calculate it, and why it matters for your online store.
What is Profit Margin?
Profit margin shows the percentage of money you keep after deducting all costs from your sales. It’s one of the most important financial metrics for any business.
👉 Formula:
Profit Margin (%) = (Selling Price – Cost Price) ÷ Selling Price × 100
Example Calculation
- Cost Price: $50
- Selling Price: $80
Profit = $80 – $50 = $30 Profit Margin = (30 ÷ 80) × 100 = 37.5%
So, you’re making a 37.5% profit margin on each sale.
Why Profit Margin Matters in E-Commerce
- Keeps your business sustainable – ensures you’re not underpricing.
- Helps with growth decisions – you’ll know if you can afford discounts or ads.
- Attracts investors or partners – healthy margins = stronger business.
Quick Tips to Improve Your Profit Margin
- Negotiate with suppliers to lower costs.
- Bundle products to increase order value.
- Use smart pricing strategies (psychological pricing, seasonal offers).
- Automate operations (using custom CMS/CRM solutions to cut manual costs).
