How it works

Calculate sales tax, total price, or original price for any purchase. This tool helps you understand the impact of sales tax (or VAT) on your spending and budgeting.

The Formula

Sales Tax Amount = Original Price × (Tax Rate / 100)
Total Price = Original Price + Sales Tax Amount
Original Price = Total Price / (1 + (Tax Rate / 100))

Worked Example

Example: Calculating Total Price with Sales Tax
You're buying a new gadget for $150. The local sales tax rate is 6.5%. To find the total price you'll pay, input '150' for Original Price and '6.5' for Tax Rate (%). The calculator will show a Sales Tax Amount of $9.75 and a Total Price of $159.75.

Tips, Assumptions & Limitations

Enter any two values to calculate the third missing value.
Ensure the tax rate is entered as a percentage (e.g., 5 for 5%).
This calculator can be used for both US sales tax and UK VAT (Value Added Tax) calculations.

FAQ

Sales tax is a consumption tax imposed by a government on the sale of goods and services. It's typically added to the retail price at the point of sale. In the US, sales tax rates vary by state and local jurisdiction. In the UK, a similar tax is called Value Added Tax (VAT).

To calculate sales tax, multiply the original price of the item by the sales tax rate (expressed as a decimal). For example, if an item is $100 and the tax rate is 5%, the sales tax is $100 * 0.05 = $5. The total price would be $100 + $5 = $105.

Yes, this calculator can be used for VAT calculations. Simply enter the price before VAT as the 'Original Price' and the VAT rate as the 'Tax Rate (%)'. The calculator will then provide the VAT amount and the total price including VAT.

Our Sales Tax Calculator is designed to work backwards! If you know the total price (including tax) and the tax rate, you can input those two values, and the calculator will determine the original price before tax and the sales tax amount.
