About My Sales Tax Calculator
My Sales Tax Calculator is a free web tool for estimating United States sales tax and the total price of a purchase. It is designed for shoppers and small sellers who know the pre-tax amount and want a quick planning estimate before checking out. The calculator covers all 50 states and the District of Columbia.
To use the main calculator, enter an amount before tax, select a state, and calculate. The results show the estimated sales tax and total including tax. The page also separates the statewide rate from the average local portion, making the combined rate easier to understand. Common purchase-amount shortcuts and a copy-result control are available on the main page.
The website explains the calculation instead of presenting the answer without context. Sales tax is the pre-tax amount multiplied by the combined rate expressed as a decimal; the total is the original amount plus that estimated tax. A linked reverse sales tax calculator handles the opposite direction when you already know the tax-inclusive total and want to work back to a pre-tax amount.
For reference, the site provides a sales-tax rate table, a full table for all 50 states and D.C., and dedicated calculator pages for ten states. Its rate information distinguishes statewide rates, population-weighted average local rates, and combined averages. An About and data-sources page explains how the rates are compiled, and the main page links to the cited Tax Foundation midyear update.
Optional city and ZIP inputs can use a sample city rate where one is available. They are not a guarantee of exact address-level tax accuracy: local districts, address details, and the circumstances of a purchase can change the applicable result. Users should confirm the correct rate before filing or collecting tax.
Calculations run in the browser. The website states that it does not save amounts, cities, or ZIP codes on a server. The tool is free to use, and its results are estimates rather than tax advice or a substitute for checking the relevant tax authority's requirements.
