Understanding Sales Tax, VAT, and GST
Whether you are a shopper trying to figure out the final price at checkout, or a business owner calculating prices for your catalog, dealing with sales tax is part of daily life. This Sales Tax Calculator works for any percentage-based tax system, including US State Sales Tax, VAT (Value Added Tax) in Europe, and GST (Goods and Services Tax) in Australia/Canada.
How Calculations Work
1. Add Tax (Forward Calculation)
Used when you see a price on a shelf (Net Price) and want to know the total you will pay at the register (Gross Price).
Total = Price + Tax Amount
2. Remove Tax (Reverse Calculation)
Used when you have a total receipt amount and need to know the original price before tax was added. This is very common for business accounting.
Tax Amount = Total - Price
Common Tax Rates (Estimates)
- USA: Varies by state. Average combined rate is roughly 6% - 10%.
- UK/Europe (VAT): Typically around 20%.
- Canada (GST/HST): Ranges from 5% to 15%.
- Australia (GST): Flat rate of 10%.
