Important to know
Estimate sales tax and a tax-inclusive total using the rate you enter.
Rates and taxability vary by location and product. This performs arithmetic only; it does not determine which tax rules apply. Use one currency with two decimal places.
Formula and methodology
Estimated tax = pre-tax amount × entered rate ÷ 100, rounded to the nearest minor unit; total = pre-tax amount + tax.
Example
At 7.5%, a pre-tax amount of 100.00 produces tax of 7.50 and a total of 107.50.
