01

Multiply the taxable price by the rate

Convert the percentage rate to a decimal, multiply by the taxable price, then add the tax amount to that price.

$100.00× 0.0825= $8.25 tax$108.25 total
02

A checkout rate may combine jurisdictions

State, county, city, and special-district components can contribute to the rate. Some goods and services are exempt or treated differently.

InputMeaning
PriceThe taxable amount before tax
RateThe combined rate that applies to this purchase
TotalPrice plus calculated tax
03

Use an official current rate

Do not infer a current rate from an old receipt or a national average. Confirm the location, product category, and effective date with the relevant state or local authority.

Scope: Practical Atlas performs the math you enter; it does not determine taxability or provide tax advice.
