Demystifying VAT: How to Calculate Tax Included and Excluded Prices
Value Added Tax (VAT) is a consumption tax assessed on the value added to goods and services. Businesses use it to account for taxes gathered from consumers and offset by taxes paid to suppliers. In many regions, including Saudi Arabia, a standard VAT rate (currently 15%) is applied to standard-rated supplies.
How VAT Calculations Work mathematically:
Two primary modes of tax estimation exist:
- Excluding Tax (Addition): To find the tax-added amount, multiply the base net figure by the VAT rate.
VAT Amount = Net Amount × (VAT Rate ÷ 100)Gross Amount = Net Amount + VAT Amount - Including Tax (Extraction): To extract the original price before VAT was added.
Net Amount = Gross Amount ÷ (1 + (VAT Rate ÷ 100))VAT Amount = Gross Amount - Net Amount
