How the difference is calculated

Same arithmetic the calculator on every page runs.

Each combined rate is the sum of its listed state, county, city and special-district components — no rounding is applied before the total. The dollar gap is the rate difference (2.75%) applied to the pre-tax amount: 2.75% of $1,000 is $27.50. Neither figure includes product-specific exemptions; groceries, clothing and digital goods can be taxed at a different rate or not at all, which is covered on each state's rules page.
