How GST / VAT Calculation Works

Adding Tax (Tax-Exclusive Price)

Tax Amount = Base Price × (Tax Rate ÷ 100)

Total Price = Base Price + Tax Amount

gstVatCalcPage.howItWorks.example: £10,000 at 20% VAT

Tax = £10,000 × 0.20 = £2,000

Total = £10,000 + £2,000 = £12,000

Removing Tax (Tax-Inclusive Price)

Base Price = Total Price ÷ (1 + Tax Rate ÷ 100)

Tax Amount = Total Price − Base Price

gstVatCalcPage.howItWorks.example: £12,000 inclusive of 20% VAT

Base = £12,000 ÷ 1.20 = £10,000

Tax = £12,000 − £10,000 = £2,000

Frequently Asked Questions

How do I calculate GST on a price?+
To add VAT: Multiply the base price by (1 + VAT rate). For example, £1,000 at 20% VAT = £1,000 × 1.20 = £1,200. To find VAT in an inclusive price: VAT = Price × Rate / (100 + Rate).
