VAT Inclusive Margin Calculator

Calculate your real margin

This calculator shows your true profit and margin when your selling price includes VAT but your costs are net.

Many businesses overestimate their margins because they forget that VAT is not part of their revenue.

To calculate real profit, VAT must be removed from the selling price before comparing it to costs.

This tool helps you understand your actual margin so you can price correctly and avoid hidden losses.

Understanding your margin

The calculator removes VAT from your selling price to reveal the true revenue your business keeps.

Your profit is calculated using this net amount, not the VAT-inclusive price.

This often results in a lower margin than expected.

How the calculation works

First, VAT is removed from the selling price to get the net value.

Then profit is calculated by subtracting cost from the net selling price.

Margin is calculated as profit divided by the net selling price.

Why VAT reduces your margin

  • VAT is not revenue: It is paid to HMRC
  • Reduces effective selling price: Your real income is lower
  • Impacts pricing strategy: Must be included in calculations
  • Hidden margin loss: Many businesses overlook this

Ignoring VAT in margin calculations can lead to underpricing and reduced profitability.

Examples

Example 1:
£120 inc VAT → £100 net → £70 cost → £30 profit → 30% margin

Example 2:
£52.50 inc VAT → £50 net → £40 cost → £10 profit → 20% margin

Example 3 (Common mistake):
Using gross price instead of net overstates margin.
