Pricing products seems simple. However, many businesses see profits disappear due to a common oversight: Value Added Tax (VAT). If you miscalculate your profit by ignoring VAT’s effect on your price, it can silently drain your earnings.
Here is our free calculator to find the info you need:
How the Pricing & Margin Calculator Works
Step 1 → Enter Net Cost ($)
➡️
This is the cost per unit before taxes. Example: if each item costs you $50 to buy or make, type 50 here.
Step 2 → Add Target Margin (%)
➡️
This is how much profit you want as a percentage of the selling price. Example: if you want a 40% margin, type 40.
Step 3 → (Optional) Add VAT Rate (%)
➡️
If your product includes VAT/sales tax, add the percentage here (like 20). If not, leave it blank.
Step 4 → (Optional) Enter Quantity
➡️
If you want totals instead of single-item results, enter how many units you’re selling.
Step 5 → Click “Calculate Pricing & Profit”
➡️ .
The calculator will instantly show you:
- Net Selling Price (the price before tax, with your margin included)
- Final Price (incl. VAT) (if VAT was entered)
- Profit per unit and totals (if quantity entered)
Value Added Tax, often shortened to VAT, is a tax on consumption. It’s charged on most goods and services and collected by businesses before being passed on to the government.
For consumers, VAT is usually already included in the price they see on the shelf. For businesses, understanding how VAT works is important not only for staying compliant but also for setting prices and calculating margins with accuracy.
The Mathematics Behind Pricing and Profit
If you’re building a spreadsheet or just want to understand the numbers behind this tool, here are the core formulas. Unless otherwise noted, all figures should be calculated excluding tax.

Setting Your Selling Price
This method works when you know your costs and the profit margin you want to achieve.
Step 1: Calculate the Net Selling Price
Net Selling Price = Cost Price ÷ (1 – Desired Margin %)
Example: $10 ÷ (1 – 0.40) = $10 ÷ 0.60 = $16.67
Step 2: Calculate the Final Selling Price
Final Selling Price = Net Selling Price × (1 + VAT Rate %)
Example: $16.67 × (1 + 0.20) = $16.67 × 1.20 = $20.00

Finding Your Real Margin
Use this approach when you already have the final retail price and want to work backward to figure out the actual margin.
Step 1: Calculate the Net Selling Price
Net Selling Price = Final Selling Price ÷ (1 + VAT Rate %)
Example: $20.00 ÷ (1 + 0.20) = $20.00 ÷ 1.20 = $16.67
Step 2: Calculate the Profit Margin
Profit Margin = ((Net Selling Price – Cost Price) ÷ Net Selling Price) × 100
Example: (($16.67 – $10.00) ÷ $16.67) × 100 = ($6.67 ÷ $16.67) × 100 = 40%
