Pay attention that the result you will get is not final. As local governments are allowed to collect their own sales taxes in addition to the state-level sales tax rate in most states, the final tax could be much more. For an accurate calculation, you need to sum up the base (statewide) rate with the county-level and local, if any.
Select the state or territory you are interested in and click on it to go to a page with a calculator dedicated to that particular location. There you will find details, as well as be able to make more accurate calculation.
