The Mechanics of Sales Tax

Sales tax is a consumption tax imposed by the government on the sale of goods and services. Depending on your region, this rate can fluctuate wildly. Our calculator allows you to either add tax to a base price (exclusive) or extract the tax amount from a final total (inclusive).

Calculation Logic

Adding Tax: Total = Base Price × (1 + Tax Rate)

Extracting Tax: Base = Total ÷ (1 + Tax Rate)

FAQ

Adding tax takes a base price and adds the tax percentage on top of it to get the final total. Extracting tax takes a final total (which already includes tax) and works backwards to find the original base price and the tax amount.

To add a 5% tax, multiply the price by 0.05 to get the tax amount, then add it to the original price. Or, simply multiply the price by 1.05 to get the total directly.
