Margin & VAT Calculator

Calculate profit margin, markup, and VAT-inclusive pricing from cost price. Supports forward and reverse calculations with margin comparison tables.

About the Margin & VAT Calculator

Pricing products and services requires understanding the interplay between cost, margin, markup, and VAT (Value Added Tax). Margin and markup are often confused — margin is profit as a percentage of selling price, while markup is profit as a percentage of cost. When VAT is added on top, the final consumer price can be significantly higher than the ex-VAT selling price.

For businesses operating in VAT jurisdictions (EU, UK, Australia, India GST, and many others), correctly separating VAT from profit calculations is essential for pricing strategy, tax compliance, and profitability analysis. VAT is collected from the consumer but must be remitted to the tax authority — it's revenue that isn't profit.

This calculator handles both forward calculations (cost + desired margin → selling price with VAT) and reverse calculations (final price → extracted VAT and profit). It provides a margin comparison table to help optimize pricing at different margin levels.

Why Use This Margin & VAT Calculator?

Pricing decisions directly impact profitability and competitiveness. This calculator prevents the common error of confusing margin with markup and properly separates VAT from profit analysis, giving you accurate pricing at any margin level.

How to Use This Calculator

  1. Choose forward mode (set margin) or reverse mode (extract from selling price)
  2. Enter the cost price excluding VAT
  3. Set your desired profit margin percentage OR enter the final selling price
  4. Enter the applicable VAT rate for your jurisdiction
  5. Set quantity for bulk calculations
  6. Review the margin comparison table to optimize your pricing

Formula

Forward: Selling Price (ex-VAT) = Cost ÷ (1 − Margin%) VAT Amount = Selling Price × VAT Rate Selling Price (inc-VAT) = Selling Price + VAT Markup% = (Profit ÷ Cost) × 100 Margin% = (Profit ÷ Selling Price) × 100

Example Calculation

Result: $171.43 inc. VAT

Cost $100 at 30% margin: Selling price = $100 ÷ 0.70 = $142.86 (ex-VAT). Plus 20% VAT = $28.57. Final price = $171.43. Profit = $42.86, markup = 42.86%.

Frequently Asked Questions

What is the difference between margin and markup?

Margin is profit ÷ selling price (e.g., $30 profit on $100 sale = 30% margin). Markup is profit ÷ cost (e.g., $30 profit on $70 cost = 42.9% markup). Same dollar profit, different percentages.

How do I calculate VAT from a VAT-inclusive price?

To extract VAT: VAT Amount = Price ÷ (1 + VAT Rate) × VAT Rate. For example, $120 with 20% VAT: VAT = $120 ÷ 1.20 × 0.20 = $20. Ex-VAT price = $100.

What VAT rates should I use?

Standard VAT rates: UK 20%, EU varies (19-27%), Australia GST 10%, India GST 5-28%, Canada GST/HST 5-15%. Some goods have reduced or zero rates.

Does VAT affect my profit margin?

No — VAT is collected from customers and paid to the government. Your profit margin should be calculated on ex-VAT prices. VAT is a pass-through, not a cost to your business.

What is a good profit margin?

It varies by industry: retail 2-5%, SaaS 70-80%, restaurants 3-9%, professional services 15-40%. Compare to industry benchmarks rather than absolute numbers.

How do I convert markup to margin?

Margin = Markup ÷ (1 + Markup). For example, 50% markup = 0.50 ÷ 1.50 = 33.3% margin. Conversely, Markup = Margin ÷ (1 − Margin).
