Sales tax calculator

Inputs

?
Enter your combined state and local sales tax rate as a percent (for example 8.25). This tool does not look up rates by address.

Estimated tax: $4.12

Total: $54.11

Common use cases

  • Estimate tax and total when you already know the combined rate from a receipt or policy table.
  • Check mental math at checkout for a single line item before paying.
  • Compare subtotal-plus-tax outcomes when toggling between two rate assumptions.

Common mistakes to avoid

  • Using one combined rate for every address

    Rates vary by city, county, and product type. This page does not look up jurisdiction-specific rules.
