Quickly calculate total cost with tax, or reverse calculate to find the pre-tax price.
Sales tax is a consumption tax imposed by the government on the sale of goods and services. It is usually calculated as a percentage of the purchase price.
Tax Amount = Price x (Tax Rate / 100)
Total Price = Price + Tax Amount
Sometimes you know the total price you paid, but need to find out what the price was before tax (e.g., for business expenses).
Original Price = Total Price / (1 + Tax Rate/100)
