How to Use This Tax Calculator
Whether you are a freelancer generating an invoice, a business owner pricing inventory, or a shopper trying to figure out how much tax you paid on a receipt, our free Tax Calculator makes the math instant and error-free. It works globally for Sales Tax, Value-Added Tax (VAT), and Goods and Services Tax (GST).
The Two Calculation Modes:
- Add Tax (Amount is Net Price): Use this when you have the base price of an item and need to know how much tax to add on top. Enter the base price, enter your local tax rate, and the calculator will instantly show you the final Gross Total you should charge.
- Extract Tax (Amount is Gross Total): Use this when you have a final receipt total and need to work backwards to find out what the original price was before taxes. Enter the total you paid, enter the tax rate, and the calculator will separate the Net Price from the Tax Amount.
The Math Behind the Tool:
To Add Tax, multiply the net price by the tax rate percentage, then add that amount to the original price.
To Extract Tax backwards from a total, the formula is: Net Price = Gross Total / (1 + Tax Rate). For example, to extract a 5% tax, you divide the total by 1.05.
