🧾 VAT & Margin Calculator

About the VAT & Margin Calculator

This free calculator brings together three everyday pricing calculations for French businesses: converting prices excluding VAT (HT — hors taxes) to prices including VAT (TTC — toutes taxes comprises) and back, working out a commercial margin (markup, margin on selling price and multiplier), and computing the VAT due on the margin by resellers of second-hand goods.

It is designed for freelancers, shopkeepers, e-merchants and second-hand dealers who need a quick, exact answer when preparing a quote, an invoice or a price list.

Key Features

• HT ↔ TTC: two-way conversion with the four French VAT rates — 20% (standard), 10% (intermediate), 5.5% (reduced), 2.1% (super-reduced) — or any custom rate (e.g. 8.5% in Guadeloupe, Martinique and Réunion). VAT is rounded to the cent and HT + VAT always equals TTC.
• Commercial margin: enter two values out of cost price, selling price and a target rate (markup on cost, margin on selling price or multiplier) to get the third, the margin in euros and all three ratios.
• VAT on the margin: VAT due by taxable dealers in second-hand goods under the margin scheme (CGI art. 297 A), with the margin and selling price excluding VAT.
• Direct links: open a tab directly with #margin or #vat-margin at the end of the address.

How to Use the Tool

• Step 1: Choose a tab: HT ↔ TTC, Commercial margin or VAT on margin.
• Step 2: HT ↔ TTC — pick a VAT rate, then enter an HT or a TTC price and click the matching button.
• Step 3: Commercial margin — enter two of the three values (in HT); results update as you type. VAT on margin — enter the purchase price and the TTC selling price.
• Step 4: Read the results; in the first tab, copy them to the clipboard in one click.

Common Use Cases

• Freelancers and companies preparing quotes and invoices.
• Shopkeepers setting a selling price from a purchase price and a target margin or multiplier.
• Second-hand dealers, antique dealers and car resellers working out the VAT due on each sale.
• Consumers checking the VAT included in a displayed price.

Tips & Best Practices

• French VAT rates: 20% for most goods and services; 10% for restaurants, passenger transport and renovation work; 5.5% for food, books, energy-efficiency renovation and heat from renewable sources (electricity and gas subscriptions have been taxed at 20% since 1 August 2025); 2.1% for reimbursable medicines and eligible press.
• Markup vs margin: the markup on cost (taux de marge) divides the margin by the cost; the margin on selling price (taux de marque) divides it by the selling price. Buying at €60 and selling at €100 gives a €40 margin, a 66.67% markup, a 40% margin on price and a 1.667 multiplier.
• Margin scheme: it only applies to goods bought without deductible VAT (from private individuals, for example). A zero or negative margin generates no VAT.
