Total Price = Net Price + VAT Amount

Removing VAT

Net Price = Gross Price ÷ (1 + VAT Rate)

VAT Amount = Gross Price − Net Price

Variables Explained

• Net Price = Original price before VAT
• Gross Price = Price including VAT
• VAT Rate = Applicable tax percentage
• VAT Amount = Tax component

These formulas are used by accountants and businesses across the UK to ensure accurate VAT reporting.

Example Calculation

Example 1: Add 20% VAT

Input:

• Net Price: £100
• VAT Rate: 20%

VAT = £100 × 20%

VAT = £20

Total = £100 + £20

Total = £120

• Net Amount: £100
• VAT Amount: £20
• Total Amount: £120

Example 2: Remove 20% VAT

Input:

• Gross Price: £120
• VAT Rate: 20%

Calculation:

Net = £120 ÷ 1.20

Net = £100

VAT = £120 − £100

VAT = £20

Result:

• Net Amount: £100
• VAT Amount: £20
• Gross Amount: £120

Example 3: Reduced VAT Rate

Input:

• Net Amount: £500
• VAT Rate: 5%
